cae4b1c73d68f1b9f6a2e76e93422ec1fd5e2472 Mon Sep 17 00:00:00 2001 From: Michael Turner Date: Thu, 17 Sep 2026 14:30:32 -0400 Subject: [PATCH 021/125] feat(bridge-sdk): Ethereum connection with three signer forms and fake JSON-RPC web3 double Adds aleo_bridge.eth.Ethereum (rpc_url+private_key, w3+signer, or bare w3 read-only/default-account forms), cached chain_id, send_transaction (local signer or default-account path), wait_for_receipt/get_receipt, and Ethereum.from_env. web3/eth_account stay lazily imported so the package still imports without the evm extra. Adds tests/fakes/fake_web3.py: a real Web3 over a hand-rolled JSON-RPC provider so tests exercise real signing/calldata against fake transport state, reusing tests.conftest.FakeAleo rather than a second Aleo fake. Updates the two plan-1 placeholder assertions in test_client.py that anticipated this change (Bridge.eth / Bridge.from_env now construct a real Ethereum connection instead of raising MissingExtraError). --- bridge-sdk/python/aleo_bridge/__init__.py | 4 +- bridge-sdk/python/aleo_bridge/_calls.py | 7 +- bridge-sdk/python/aleo_bridge/eth.py | 166 ++++++++++++++ bridge-sdk/tests/fakes/__init__.py | 0 bridge-sdk/tests/fakes/fake_web3.py | 225 +++++++++++++++++++ bridge-sdk/tests/test_client.py | 14 +- bridge-sdk/tests/test_eth_connection.py | 126 +++++++++++ bridge-sdk/tests/test_import_without_web3.py | 28 +++ 8 files changed, 563 insertions(+), 7 deletions(-) create mode 100644 bridge-sdk/python/aleo_bridge/eth.py create mode 100644 bridge-sdk/tests/fakes/__init__.py create mode 100644 bridge-sdk/tests/fakes/fake_web3.py create mode 100644 bridge-sdk/tests/test_eth_connection.py create mode 100644 bridge-sdk/tests/test_import_without_web3.py diff --git a/bridge-sdk/python/aleo_bridge/__init__.py b/bridge-sdk/python/aleo_bridge/__init__.py index c5566adf..207be0c7 100644 --- a/bridge-sdk/python/aleo_bridge/__init__.py +++ b/bridge-sdk/python/aleo_bridge/__init__.py @@ -21,10 +21,11 @@ MintReceipt, Plan, PreparedTx, PrivacyReceipt, Progress, Quote, Receipt, SolanaHyperlaneQuote, Status, Step, to_progress, ) -from ._calls import AleoCall # noqa: E402 +from ._calls import AleoCall, EvmCall # noqa: E402 from .checkpoint import Checkpoint, CheckpointStore, FileCheckpointStore, create_checkpoint # noqa: E402 from .circle import CircleClient # noqa: E402 from .client import Bridge # noqa: E402 +from .eth import Ethereum, EthModule # noqa: E402 from .freezelist import EMPTY_MERKLE_PROOF_PAIR, FreezeList # noqa: E402 from .hyperlane import HyperlaneModule # noqa: E402 from .privacy import PrivacyModule # noqa: E402 @@ -45,4 +46,5 @@ "AleoCall", "Bridge", "CircleClient", "DEFAULT_ENDPOINT", "EMPTY_MERKLE_PROOF_PAIR", "FreezeList", "HyperlaneModule", "PrivacyModule", "Profile", "XReserveModule", "Checkpoint", "CheckpointStore", "FileCheckpointStore", "create_checkpoint", + "EthModule", "Ethereum", "EvmCall", ] diff --git a/bridge-sdk/python/aleo_bridge/_calls.py b/bridge-sdk/python/aleo_bridge/_calls.py index d1735c99..e9c89b0e 100644 --- a/bridge-sdk/python/aleo_bridge/_calls.py +++ b/bridge-sdk/python/aleo_bridge/_calls.py @@ -209,4 +209,9 @@ def submit_prepared(self, prepared: PreparedTx, *, wait: bool = True, wait_timeo return self._build(prepared.transaction_id, root_outputs(decoded, self.program_id, self.function_name)) -__all__ = ["AleoCall", "extract_tx_id", "is_duplicate_submission", "output_values", "payload_transitions", "root_outputs"] +class EvmCall: + """Completed in Task 2.""" + + +__all__ = ["AleoCall", "EvmCall", "extract_tx_id", "is_duplicate_submission", "output_values", "payload_transitions", + "root_outputs"] diff --git a/bridge-sdk/python/aleo_bridge/eth.py b/bridge-sdk/python/aleo_bridge/eth.py new file mode 100644 index 00000000..0925ccc3 --- /dev/null +++ b/bridge-sdk/python/aleo_bridge/eth.py @@ -0,0 +1,166 @@ +"""Ethereum connection and the ``bridge.eth`` module (Hyperlane + xReserve, Ethereum origin). + +``web3`` and ``eth_account`` are imported lazily so ``import aleo_bridge`` works +without the ``evm`` extra; the first call that needs them raises +``MissingExtraError("evm", ...)``. +""" +from __future__ import annotations + +import os +from typing import Any, Mapping + +from .errors import ConfigurationError, MissingExtraError + + +def _web3(): + try: + import web3 + except ImportError as exc: # pragma: no cover - exercised by test_import_without_web3 + raise MissingExtraError("evm", "Ethereum connections") from exc + return web3 + + +def _eth_account(): + try: + from eth_account import Account + except ImportError as exc: # pragma: no cover + raise MissingExtraError("evm", "Ethereum signing") from exc + return Account + + +class Ethereum: + """Transport + optional signer for Ethereum-origin bridge actions. + + Three interchangeable forms:: + + Ethereum(rpc_url, private_key=key) # SDK builds Web3(HTTPProvider(rpc_url)) + Ethereum(w3=my_w3, signer=local_account) # caller's Web3, caller's eth_account signer + Ethereum(w3=my_w3) # signs via w3.eth.default_account + caller middleware, + # else read-only + + Sending: with a ``LocalAccount`` the SDK fills nonce/gas/fee fields, signs, and + ``send_raw_transaction``s; in default-account mode it calls + ``w3.eth.send_transaction`` so the caller's middleware signs.

fake_web3._decode_raw now keeps nonce/gas/gasPrice/maxFeePerGas/maxPriorityFeePerGas from the signed raw tx instead of discarding them, so tests can assert send_transaction's exact fee-filling arithmetic (gas = estimate * 1.2; EIP-1559 maxFeePerGas = baseFee * 2 + tip). - FakeRpcProvider gains a legacy=True knob that omits baseFeePerGas from eth_getBlockByNumber, exercising eth.py's previously-unreachable legacy gasPrice branch. - FakeRpcProvider gains receipt_delay/receipt_poll_counts so a receipt can stay pending for N polls per hash; test_evm_call's ordering test now proves each checkpoint fires with zero receipt polls for its own hash, that polling only starts after, and that approvals fully confirm before the main call is broadcast. No production code changes: eth.py's fee formula and _calls.py's checkpoint-before-poll ordering were both already correct; the gap was in test strength only. --- bridge-sdk/tests/fakes/fake_web3.py | 44 ++++++++++++++++++------- bridge-sdk/tests/test_eth_connection.py | 25 ++++++++++++++ bridge-sdk/tests/test_evm_call.py | 39 +++++++++++++++++++++- 3 files changed, 96 insertions(+), 12 deletions(-) diff --git a/bridge-sdk/tests/fakes/fake_web3.py b/bridge-sdk/tests/fakes/fake_web3.py index 290f5f63..d9aae648 100644 --- a/bridge-sdk/tests/fakes/fake_web3.py +++ b/bridge-sdk/tests/fakes/fake_web3.py @@ -74,7 +74,13 @@ def deposited_log(xreserve: str, *, local_token: str, depositor: str, remote_rec def _decode_raw(raw: bytes) -> dict: - """Signed raw tx → {to, value, data, from}.

feat(bridge-sdk): wire the Solana connection into Bridge (sol property, from_env, status) - Bridge.__init__ eagerly wraps a bare solana-py client into Solana(client=...) and builds a SolModule up front, so bridge.solana is always Solana | None and bridge.sol never lazily imports solders. - solana_from_env() now delegates to Solana.from_env(), picking up the BRIDGE_SOLANA_PRIVATE_KEY/BRIDGE_LIVE_SOLANA_RPC_URL aliases it already supports. - status() appends a solana ChainStatus (address, can_sign, solana/sol balance) when configured. - Export SolModule, SolCall and DEFAULT_SOLANA_RPC_URL from the package alongside Solana. - sol.py: _AsyncClientAdapter.close() stops its private event-loop thread (idempotent); Solana.close() duck-types the wrapped client's close() and Solana is now a context manager. - Fix two from_env/from_profile tests that didn't clear the Solana env aliases, so the dev shell's BRIDGE_SOLANA_PRIVATE_KEY no longer leaks into their bridge.solana is None assertions. --- bridge-sdk/python/aleo_bridge/__init__.py | 6 +- bridge-sdk/python/aleo_bridge/client.py | 45 ++++++------ bridge-sdk/python/aleo_bridge/sol.py | 24 +++++++

A returned id that differs from the signed one raises rather than checkpointing an id that follows the wrong transaction. The fakes now echo the real id (keccak of the raw EVM tx, the transaction's own Solana signature) instead of an invented one, so the echo check is exercised for real; tests read hashes back with provider.hash_at(n) / fake.sent_signature() and arm the pending/reverted/receipt_delay knobs by send order. --- bridge-sdk/python/aleo_bridge/eth.py | 17 ++++- bridge-sdk/python/aleo_bridge/sol.py | 17 ++++- bridge-sdk/tests/fakes/fake_solana.py | 18 +++++- bridge-sdk/tests/fakes/fake_web3.py | 38 +++++++++-- bridge-sdk/tests/test_eth_connection.py | 42 +++++++++++-- .../tests/test_eth_hyperlane_execute.py | 28 ++++----- bridge-sdk/tests/test_eth_xreserve_execute.py | 26 ++++---- bridge-sdk/tests/test_evm_call.py | 63 ++++++++++++------- bridge-sdk/tests/test_sol_send.py | 62 +++++++++++++----- 9 files changed, 229 insertions(+), 82 deletions(-) diff --git a/bridge-sdk/python/aleo_bridge/eth.py b/bridge-sdk/python/aleo_bridge/eth.py index dd4e7bf7..addbf3d5 100644 --- a/bridge-sdk/python/aleo_bridge/eth.py +++ b/bridge-sdk/python/aleo_bridge/eth.py @@ -182,7 +182,22 @@ def send_transaction(self, tx: dict) -> str: tx["maxPriorityFeePerGas"] = tip tx["maxFeePerGas"] = int(base_fee) * 2 + tip signed = self._signer.sign_transaction(tx) - return Web3.to_hex(self._w3.eth.send_raw_transaction(signed.raw_transaction)) + # The hash is fixed by the signature, so it exists before the broadcast.

Aleo legs prove (DPS or local), checkpoint the exact prepared transaction BEFORE broadcasting it, submit with wait=False and checkpoint the id; EVM and Solana legs go through the modules' own plan= surface so the route, registry version, sender and every plan field are re-validated where the transaction is built. A private xReserve mint now requires its own secret_nonce (never the 0scalar default), the Hyperlane hook payment is re-quoted at the last moment unless pinned, and a destination-balance baseline is captured only when the destination connection is the recipient. _Emitter feeds both checkpoint channels: a module's already-reduced Checkpoint and execute()'s own post-send emission reduce to the same value, so the caller sees each boundary once and the bound store keeps exactly one record per transfer, superseding the id it replaces. The write-side fakes gain the real plan= signatures, and lifecycle.quote now calls bridge.sol.quote_transfer_remote(plan=plan) without the positional recipient workaround. --- bridge-sdk/python/aleo_bridge/lifecycle.py | 248 ++++++++++++++++++++- bridge-sdk/tests/fakes/fake_bridge.py | 136 ++++++++--- bridge-sdk/tests/test_execute.py | 244 ++++++++++++++++++++ 3 files changed, 593 insertions(+), 35 deletions(-) create mode 100644 bridge-sdk/tests/test_execute.py diff --git a/bridge-sdk/python/aleo_bridge/lifecycle.py b/bridge-sdk/python/aleo_bridge/lifecycle.py index b2c700e2..3d3ed4f3 100644 --- a/bridge-sdk/python/aleo_bridge/lifecycle.py +++ b/bridge-sdk/python/aleo_bridge/lifecycle.py @@ -15,8 +15,10 @@ import re from dataclasses import dataclass, replace +from typing import Any, Callable from ._plan import build_plan +from .checkpoint import Checkpoint, create_checkpoint from .errors import ( CheckpointInvalidError, ConfigurationError, @@ -27,7 +29,8 @@ UnsupportedRouteError, ) from .registry import Asset, Chain, Registry, Route -from .types import AleoHyperlaneQuote, AleoXReserveQuote, Fee, Plan, Quote +from .types import (TERMINAL, AleoHyperlaneQuote, AleoXReserveQuote, Fee, Plan, Progress, Quote, + Receipt, Status, to_progress) from .units import format_decimal_amount, parse_decimal_amount, resolve_amount MINT_MODES = ("public", "record", "private") @@ -181,10 +184,7 @@ def quote(bridge, *, source, destination, amount=None, amount_atomic=None, recip q = _module(bridge, "eth").quote_transfer_remote(plan=plan) return replace(q, plan=plan) if plan.protocol == "hyperlane" and family == "solana": - # Unlike EthModule's quote methods, SolModule.quote_transfer_remote's ``recipient`` has - # no default — it is a required positional argument even though it is fully overwritten - # from ``plan`` on the real module's plan branch. - q = _module(bridge, "sol").quote_transfer_remote(plan.recipient, plan=plan) + q = _module(bridge, "sol").quote_transfer_remote(plan=plan) return replace(q, plan=plan) if plan.protocol == "hyperlane" and family == "aleo": gas = bridge.hyperlane.quote_gas_payment(plan.source_asset_id) @@ -219,4 +219,240 @@ def quote(bridge, *, source, destination, amount=None, amount_atomic=None, recip f"Unsupported {plan.protocol} source chain family: {family} ({plan.route_id})") -__all__ = ["MINT_MODES", "ResolvedRoute", "prepare", "quote", "resolve_route"] +# ── Checkpoint emission ─────────────────────────────────────────────────────── + +def _persist(bridge, checkpoint: Checkpoint, receipt: Receipt | None, *, previous_id: str | None = None) -> None: + """Mirror *checkpoint* into the bound store: supersede the previous id, drop terminal ones. + + ``receipt`` is ``None`` for a boundary the protocol module reduced and saved itself: the + supersede still runs (a module only ever saves — it never deletes the checkpoint its own + next boundary replaces), the save does not. + """ + store = getattr(bridge, "checkpoints", None) + if store is None: + return + if previous_id is not None and previous_id != checkpoint.id: + store.delete(previous_id) + if receipt is None: + return + if receipt.status in TERMINAL: + store.delete(checkpoint.id) + else: + store.save(checkpoint) + + +class _Emitter: + """Turns receipts into checkpoints: caller callback first, then the bound store. + + Two channels feed it — a protocol module's own ``on_checkpoint`` (which hands over a + ``Checkpoint`` it has already reduced and saved) and ``execute``'s own emission once the + send returns.

The mismatch branch now carries broadcast_id, so EvmCall refuses a resend instead of signing a second transfer. R2: _AsyncClientAdapter.close() bounds the wrapped client's close() by the timeout, swallows its failure and stops the loop in a finally, setting _closed only once that stop is issued — a third-party transport that cannot close no longer leaves the private loop thread running with a second close() turned into a no-op. R3: comments the default-account path, where the hash is not knowable until the node answers, so none of these protections apply; a local signer is the right choice for funds-moving calls. --- bridge-sdk/python/aleo_bridge/eth.py | 13 ++++++++- bridge-sdk/python/aleo_bridge/sol.py | 29 ++++++++++++------- bridge-sdk/tests/test_evm_call.py | 16 +++++++++++ bridge-sdk/tests/test_sol_connection.py | 38 +++++++++++++++++++++++++ 4 files changed, 84 insertions(+), 12 deletions(-) diff --git a/bridge-sdk/python/aleo_bridge/eth.py b/bridge-sdk/python/aleo_bridge/eth.py index 9be39dc4..a5df0962 100644 --- a/bridge-sdk/python/aleo_bridge/eth.py +++ b/bridge-sdk/python/aleo_bridge/eth.py @@ -168,6 +168,12 @@ def send_transaction(self, tx: dict) -> str: tx.setdefault("chainId", self.chain_id) tx.setdefault("value", 0) if self._signer is None: + # Default-account mode: the caller's middleware signs, so the hash only exists once the node + # answers.

20:11:11 -0400 Subject: [PATCH 073/125] fix(bridge-sdk): save-then-delete checkpoints, gate Aleo legs on the connected address, and make destination-balance reads best-effort Task 4 review carry-overs: _persist now saves (or drops, if terminal) the new checkpoint before deleting the id it supersedes, never the reverse, so a crash between the two steps can't leave the store holding neither. A module-emitted checkpoint's supersede is deferred on the _Emitter (_pending_supersede) until the module has actually saved it -- flushed at the next emission or via execute()'s new finalize() call. Aleo hyperlane/xreserve legs now call _assert_sender against a guarded bridge.aleo_address() before proving, refusing a plan built for a different account. _read_destination_balance wraps its RPC read in try/except so an advisory baseline read never blocks funds movement. --- bridge-sdk/python/aleo_bridge/lifecycle.py | 103 ++++++++++++++++----- bridge-sdk/tests/test_execute.py | 81 ++++++++++++++++ 2 files changed, 160 insertions(+), 24 deletions(-) diff --git a/bridge-sdk/python/aleo_bridge/lifecycle.py b/bridge-sdk/python/aleo_bridge/lifecycle.py index 37289c09..511bc4d1 100644 --- a/bridge-sdk/python/aleo_bridge/lifecycle.py +++ b/bridge-sdk/python/aleo_bridge/lifecycle.py @@ -223,41 +223,48 @@ def quote(bridge, *, source, destination, amount=None, amount_atomic=None, recip # ── Checkpoint emission ─────────────────────────────────────────────────────── -def _persist(bridge, checkpoint: Checkpoint, receipt: Receipt | None, *, previous_id: str | None = None) -> None: - """Mirror *checkpoint* into the bound store: supersede the previous id, drop terminal ones. - - ``receipt`` is ``None`` for a boundary the protocol module reduced and saved itself: the - supersede still runs (a module only ever saves — it never deletes the checkpoint its own - next boundary replaces), the save does not. +def _persist(bridge, checkpoint: Checkpoint, receipt: Receipt, *, previous_id: str | None = None) -> None: + """Mirror *checkpoint* into the bound store: save (or drop, if terminal) BEFORE superseding + the previous id — never the reverse, so a crash between the two steps still leaves a valid + record for the transfer rather than a moment where the store holds neither.

An Aleo leg rebroadcasts the checkpointed bytes byte-for-byte after checking the serialized payload's own id, and treats the node's duplicate answer as success (plan 1's is_duplicate_submission, re-exported as is_duplicate_broadcast_error rather than reimplemented) - so the transfer can only ever exist once on chain.

Solana legs have no resumable state and say so instead of guessing. complete() submits the one user-signed Aleo transaction a private USDCx mint needs: it rebroadcasts an already-proved destination transaction, or builds the mint (the module re-verifies that (recipient, secret_nonce) opens the attested commitment, so a wrong nonce never reaches proving), proves it, checkpoints the exact bytes BEFORE broadcast, then broadcasts. secret_nonce is mandatory for a private resume/complete and is refused before any RPC; it is never written to a receipt, a checkpoint or a Progress. --- bridge-sdk/python/aleo_bridge/lifecycle.py | 243 ++++++++++++++- bridge-sdk/tests/test_resume_complete.py | 346 +++++++++++++++++++++ 2 files changed, 585 insertions(+), 4 deletions(-) create mode 100644 bridge-sdk/tests/test_resume_complete.py diff --git a/bridge-sdk/python/aleo_bridge/lifecycle.py b/bridge-sdk/python/aleo_bridge/lifecycle.py index 25be306a..1ba69707 100644 --- a/bridge-sdk/python/aleo_bridge/lifecycle.py +++ b/bridge-sdk/python/aleo_bridge/lifecycle.py @@ -20,23 +20,26 @@ from typing import Any, Callable from . import _sealevel +from ._calls import is_duplicate_submission from ._plan import build_plan from .checkpoint import Checkpoint, create_checkpoint from .errors import ( + AttestationError, BridgeError, CheckpointInvalidError, ConfigurationError, DeliveryUnknownError, InvalidAmountError, InvalidRecipientError, + NotResumableError, PollingTimeoutError, RegistryVersionMismatchError, RouteUnavailableError, UnsupportedRouteError, ) from .registry import Asset, Chain, Registry, Route -from .types import (CALLER_BOUNDARIES, TERMINAL, AleoHyperlaneQuote, AleoXReserveQuote, Fee, Plan, - Progress, Quote, Receipt, Status, to_progress) +from .types import (CALLER_BOUNDARIES, TERMINAL, AleoHyperlaneQuote, AleoXReserveQuote, Attestation, + Fee, Plan, Progress, Quote, Receipt, Status, to_progress) from .units import format_decimal_amount, parse_decimal_amount, resolve_amount MINT_MODES = ("public", "record", "private") @@ -860,8 +863,9 @@ def wait(bridge, progress: Progress, *, until=None, poll_seconds: float = 15.0, time.sleep(interval) -__all__ = ["MINT_MODES", "ResolvedRoute", "aleo_transaction_status", "execute", "get_status", "prepare", - "quote", "recover", "resolve_route", "wait"] +__all__ = ["MINT_MODES", "ResolvedRoute", "aleo_transaction_status", "complete", "execute", "get_status", + "is_duplicate_broadcast_error", "prepare", "quote", "recover", "resolve_route", "resume", + "submit_serialized", "wait"] # ── recover ─────────────────────────────────────────────────────────────────── @@ -1026,3 +1030,234 @@ def recover(bridge, checkpoint) -> Progress: protocol_state={**receipt.protocol_state, "preparedDestinationTransaction": prepared_dest["serializedTransaction"]}) return _finish(bridge, plan, receipt, cp.id) + + +# ── Idempotent Aleo rebroadcast (invariant 3) ───────────────────────────────── + +#: Plan 1's duplicate-broadcast classifier, re-exported under the lifecycle's own name. +#: +#: It is deliberately NOT reimplemented here: ``AleoCall.submit_prepared`` already applies exactly +#: this rule to every prepared broadcast, and two rules that could ever disagree about "is this a +#: duplicate?" is one rule too many for a funds-critical path.

requires the checkpointed xReserve hook; complete never persists secrets (store-level test) The hook-equality guard in resume's xReserve branch only ran when protocol_state carried a hookData string, so a receipt without one passed it vacuously and the deposit could be re-hooked to a freshly derived commitment. Require the hook to be present and a 65-byte 0x hex string (encoding.HOOK_DATA_BYTES, the same shape EthModule._recover_xreserve enforces) in the pre-RPC block, before the history scan, so a transfer resume() cannot finish is not even scanned; the equality guard below is now unconditional. Every receipt recover() produces already carries hookData, so this only refuses hand-built, truncated or legacy ones. Also: assert at the store level that complete() writes neither the secret nonce, Circle's attestation nor the committed hook into any checkpoint file, and say in resume's docstring that a SOURCE_APPROVAL_PENDING receipt needs recover() first. --- bridge-sdk/python/aleo_bridge/lifecycle.py | 17 +++++++-- bridge-sdk/tests/test_resume_complete.py | 43 ++++++++++++++++++++++ 2 files changed, 57 insertions(+), 3 deletions(-) diff --git a/bridge-sdk/python/aleo_bridge/lifecycle.py b/bridge-sdk/python/aleo_bridge/lifecycle.py index 5e9d37b5..cecfef0b 100644 --- a/bridge-sdk/python/aleo_bridge/lifecycle.py +++ b/bridge-sdk/python/aleo_bridge/lifecycle.py @@ -21,6 +21,7 @@ from . import _sealevel from ._calls import is_duplicate_submission +from .encoding import HOOK_DATA_BYTES from ._plan import build_plan from .checkpoint import Checkpoint, create_checkpoint from .errors import ( @@ -1079,7 +1080,9 @@ def resume(bridge, progress: Progress, *, on_checkpoint: Callable | None = None, """Finish the source leg an interruption left unsubmitted — never repeats an irreversible step.

Reads are open; every write needs confirm=true and otherwise returns the quote (or recovered progress / built call) plus how_to_confirm, having moved nothing. bridge_execute takes the quote inputs, never a plan, and re-quotes internally; confirmed writes hand back {progress, checkpoint} so the model can feed the checkpoint to bridge_get_progress / bridge_resume / bridge_complete later. Three safety rules on top of the plain surface: - a private mint never gets a defaulted secret: mint_mode=private without a secret_nonce (and bridge_complete without one, unless the mint is already proved) is a structured error that quotes nothing and moves nothing; - secrets never leave the process: rendered receipts drop the private-mint secret, record plaintext, the Circle attestation body and the proved transaction bytes, and no tool echoes its own arguments back; - BridgeErrors come back as {error, error_type, how_to_fix} instead of crashing the model's loop - unconfigured Ethereum/Solana connections are probed up front, and an ambiguous source send also carries next="recover" with the last checkpoint, since these calls are single-use. EvmXReserveQuote renders a synthetic "xReserve max fee" fee entry from max_fee_atomic, which its empty fees tuple would otherwise hide. Also lands the exports task 9 deferred: bridge_tools, dispatch_tool and agent_guide() (the packaged AGENTS.md, or a pointer at codegen/gen_context.py until task 12 generates it), with the export-pinning test extended. --- bridge-sdk/python/aleo_bridge/__init__.py | 23 ++ bridge-sdk/python/aleo_bridge/agent.py | 412 ++++++++++++++++++++++ bridge-sdk/tests/fakes/fake_bridge.py | 12 +- bridge-sdk/tests/test_agent.py | 291 +++++++++++++++ bridge-sdk/tests/test_client_lifecycle.py | 21 +- 5 files changed, 751 insertions(+), 8 deletions(-) create mode 100644 bridge-sdk/python/aleo_bridge/agent.py create mode 100644 bridge-sdk/tests/test_agent.py diff --git a/bridge-sdk/python/aleo_bridge/__init__.py b/bridge-sdk/python/aleo_bridge/__init__.py index ca61c7e7..7d2aabb1 100644 --- a/bridge-sdk/python/aleo_bridge/__init__.py +++ b/bridge-sdk/python/aleo_bridge/__init__.py @@ -6,6 +6,8 @@ """ from __future__ import annotations +from pathlib import Path + __version__ = "0.1.0" from .errors import ( # noqa: E402 @@ -30,6 +32,7 @@ from .hyperlane import HyperlaneModule # noqa: E402 from . import lifecycle # noqa: E402 from .lifecycle import prepare # noqa: E402 +from .agent import bridge_tools, dispatch_tool # noqa: E402 from .privacy import PrivacyModule # noqa: E402 from .profile import DEFAULT_ENDPOINT, Profile # noqa: E402 from .sol import DEFAULT_SOLANA_RPC_URL, Solana, SolModule # noqa: E402 @@ -52,4 +55,24 @@ "EthModule", "Ethereum", "EvmCall", "DEFAULT_SOLANA_RPC_URL", "Solana", "SolCall", "SolModule", "lifecycle", "prepare", + "agent_guide", "bridge_tools", "dispatch_tool", ] + +AGENTS_FILE = "AGENTS.md" + + +def agent_guide() -> str: + """The packaged agent guide: the prose a model reads alongside :func:`bridge_tools`. + + ``AGENTS.md`` is generated from the registry and the lifecycle docstrings by + ``codegen/gen_context.py`` and shipped inside the wheel.

The same `secret_nonce` is required by `complete`; the SDK + **never stores** it and checkpoints exclude it (and every other secret). + Tell the user to keep it (the default `0scalar` needs no storage but adds + no entropy). Only the recipient's Aleo key can complete a private mint — + make sure the recipient IS the configured Aleo address before depositing. +7. Aleo-origin Hyperlane transfers spend PUBLIC balances: `unshield` a private + record first. Hyperlane delivers into public balances; `shield` afterwards + if the user wants privacy. Private xReserve burns spend records directly. + +### While acting + +8. Writes are slow (proving + confirmation ≈ a minute or two on Aleo; Circle + attestation and Hyperlane relay take minutes). Never re-submit because a + call seems slow — `status()` / `recover` first. +9. Confirm, act, report ids. Errors name their own fix — read the exception + message and do what it says. + + +## Tier 2 — the protocol modules (building your own flows) + +Every Aleo write returns an `AleoCall`: nothing touches the network until +`.simulate()` (free), `.prove()` / `.delegate_prepared()` (proved, not +broadcast — checkpoint it), `.submit_prepared()`, `.transact()` (local +proving + broadcast) or `.delegate()` (DPS + broadcast). EVM and Solana +writes return `EvmCall` / `SolCall` with `.build()` (unsigned) and `.send()`. +The lifecycle verbs above compose these; use them directly only when you +need a single leg.

The private-mint secret nonce is new relative to veil: it is generated once per case, written to .secret with O_CREAT|O_EXCL and mode 0600, and the state JSON records only secretNoncePresent, so a state file can be shared without leaking the commitment secret. tests/test_live_helpers.py mirrors veil's helpers.test.ts (gating truth table, state round-trip and fail-closed cases, one-atomic-unit formatting, bytea hashes, rejected Aleo transactions) and adds the secret-file mode/exclusivity checks and the explorer 429/5xx tolerance. --- bridge-sdk/tests/live/config.py | 141 +++++++++ bridge-sdk/tests/live/helpers.py | 393 +++++++++++++++++++++++++ bridge-sdk/tests/test_live_helpers.py | 407 ++++++++++++++++++++++++++ 3 files changed, 941 insertions(+) create mode 100644 bridge-sdk/tests/live/config.py create mode 100644 bridge-sdk/tests/live/helpers.py create mode 100644 bridge-sdk/tests/test_live_helpers.py diff --git a/bridge-sdk/tests/live/config.py b/bridge-sdk/tests/live/config.py new file mode 100644 index 00000000..e0572fe5 --- /dev/null +++ b/bridge-sdk/tests/live/config.py @@ -0,0 +1,141 @@ +"""Gates and paths for the funded live cases — a port of veil's `test/integration/live/config.ts`. + +Every function here only READS the environment.

5d67bc1c70ff92611a7a1b7a1d5592237b2a1ef5 Mon Sep 17 00:00:00 2001 From: Michael Turner Date: Fri, 18 Sep 2026 15:01:11 -0400 Subject: [PATCH 088/125] feat(bridge-sdk): live cases + rehearse CLI over the public lifecycle verbs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit tests/live/cases.py ports veil's five mainnet cases as functions the pytest suite (13b) and the operator CLI both call, so the two cannot drift. Each case loads its route-qualified state file, quotes, prints the route/amount/fee table, prechecks balances (Underfunded carries the shortfall so callers can skip), and — only when the caller passes execute=True — executes once, drops the in-memory progress, recovers from the checkpoint on disk and drives wait/resume/complete to done. execute is never retried after a broadcast. Case parametrization covers every registry route per case, in both directions, with non-active routes reported as skipped-by-registry rather than dropped. veil's literals are kept: '2' USDC for the private mint, '2.000001' USDCx for the private burn, one atomic unit elsewhere, signer mode for Aleo Hyperlane. The Aleo Hyperlane IGP payment comes from our own quote rather than veil's operator-supplied fee variable. scripts/rehearse.py runs one case over its routes with --case/--route/ --quote-only/--recover/--report and exits 0/1/2 (ok/failed/pending). It only reads the acknowledgement variables, prints no line that would set one, and prints the --recover command for anything left pending. --- bridge-sdk/scripts/rehearse.py | 230 +++++++++++++ bridge-sdk/tests/live/cases.py | 460 ++++++++++++++++++++++++++ bridge-sdk/tests/test_live_helpers.py | 444 +++++++++++++++++++++++++ 3 files changed, 1134 insertions(+) create mode 100644 bridge-sdk/scripts/rehearse.py create mode 100644 bridge-sdk/tests/live/cases.py diff --git a/bridge-sdk/scripts/rehearse.py b/bridge-sdk/scripts/rehearse.py new file mode 100644 index 00000000..5efb224b --- /dev/null +++ b/bridge-sdk/scripts/rehearse.py @@ -0,0 +1,230 @@ +#!/usr/bin/env python3 +"""Operator front-end over the live cases in ``tests/live/cases.py``. + + python scripts/rehearse.py --case evm-hyperlane --quote-only # price every route, submit nothing + python scripts/rehearse.py --case evm-hyperlane --route hyperlane:ethereum/eth->aleo/eth + python scripts/rehearse.py --recover # continue one interrupted transfer + python scripts/rehearse.py --case solana-hyperlane --report run.json + +The CLI and the pytest suite call the SAME case functions, so a rehearsal and a test cannot drift. + +This script never sets, exports, prints or suggests a value for an acknowledgement variable.

Never keys, record plaintext, `secret_nonce`, +attestations, payloads or hashes. `recover` re-resolves the route from the live +registry and refuses a registry-version mismatch. Idempotent rebroadcast: a +duplicate-transaction response from the node is success. `FileCheckpointStore` +writes mode-600 files via an atomic rename; profile checkpoints (under +`~/.aleo-bridge/`) get the same treatment. `Bridge(checkpoints=store)` also +auto-saves through every lifecycle call, the same channel Ethereum, Solana and +Aleo writes all use — you don't have to pass `on_checkpoint=` yourself unless +you want a second sink. + +## Private USDCx mints + +`mint_mode="private"` commits `(recipient, secret_nonce)` on Ethereum; only the +recipient's Aleo key can `complete` the mint, with the same `secret_nonce`.

absence tolerated). - source_status turns a checkpointed hash the node has forgotten, whose nonce the account has moved past, into EXPIRED with sourceError/dropped. recover_source stays history-first: a dispatch found in the logs wins, and only a scan that ran and matched nothing makes a dropped hash resumable (SOURCE_SUBMISSION_PENDING);

From: Michael Turner Date: Tue, 22 Sep 2026 13:38:06 -0400 Subject: [PATCH 107/125] fix(bridge-sdk): recovery log scans survive a lagging RPC head MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The live run's recovery scan died on publicnode with -32602 'block range extends beyond current head block' for blocks 26034459-26034469 — a range its own eth_blockNumber had just handed out. The endpoint is load-balanced, so the node answering eth_getLogs was behind the node that reported the head. - eth.HEAD_RACE_RE matches only head-block phrasings ('beyond current head', 'head block', 'exceeds ... head'), so a genuine range-too-large or too-many-results error still fails loudly. - _scan_logs retries such a chunk up to LOG_SCAN_HEAD_RACE_RETRIES (5) times, pausing LOG_SCAN_HEAD_RACE_SLEEP_SECONDS (0.5, via the injectable EthModule.sleep) and re-reading the head each time. The scan's upper bound only ever moves DOWN to the answering node's head, which also clamps the initial one. Exhausting the retries still raises BridgeError: a scan that cannot finish must never read as an empty history. - lifecycle._is_transient_error matches the same message, so wait() polls again instead of aborting the transfer. --- bridge-sdk/python/aleo_bridge/eth.py | 69 ++++++++++++++++++---- bridge-sdk/python/aleo_bridge/lifecycle.py | 5 ++ bridge-sdk/tests/test_eth_recover.py | 63 ++++++++++++++++++++ 3 files changed, 126 insertions(+), 11 deletions(-) diff --git a/bridge-sdk/python/aleo_bridge/eth.py b/bridge-sdk/python/aleo_bridge/eth.py index 66209ebc..695cdf88 100644 --- a/bridge-sdk/python/aleo_bridge/eth.py +++ b/bridge-sdk/python/aleo_bridge/eth.py @@ -8,6 +8,7 @@ import os import re +import time from dataclasses import dataclass, fields from typing import Any, Mapping @@ -53,6 +54,26 @@ def _web3(): """ +HEAD_RACE_RE = re.compile(r"beyond current head|head block|exceeds.*head", re.IGNORECASE) +"""A JSON-RPC error that means "your ``toBlock`` is ahead of the block I have", not a bad request. + +A load-balanced endpoint answers ``eth_blockNumber`` and ``eth_getLogs`` from different nodes, so a +range bounded by one node's head can be beyond another's: on 2026-09-22 publicnode answered a +recovery scan with ``-32602 block range extends beyond current head block`` for a range it had +itself just handed out.

The live suite builds a fresh Ethereum per phase and per leg — exactly the incident's topology — so a per-instance counter reset precisely where the replacement happened. Per process, not across processes or machines; last_broadcast_nonce stays per instance. - A dropped verdict now needs TWO eth_getTransactionByHash misses, separated by DROPPED_REPROBE_SLEEP_SECONDS, so one lagging backend of a load-balanced endpoint cannot declare a live transaction dead. The verdict carries the head it was taken at, and recover_source only calls a transfer resumable when the history scan ran AND its (clamped) head reached that far; otherwise EXPIRED with 'retry recover()'. - A terminal receipt carrying dropped is kept in the checkpoint store, not deleted (lifecycle._keeps_checkpoint, honoured by _persist and _finish); the pair is allowlisted into the checkpoint so an offline pending() listing shows it as failed-and-explained instead of still confirming. - The sourceError says what to do: with approvals, recover() then resume(); with none, inspect the sender's transactions at that nonce — a fresh execute is required. Every EXPIRED one ends with 'the checkpoint is kept'. - min_priority_fee_wei is a validated property, also read from BRIDGE_MIN_PRIORITY_FEE_WEI by from_env. - HEAD_RACE_RE is word-bounded, so 'max header size' and 'overhead block cache' are not head races. --- bridge-sdk/README.md | 25 ++- bridge-sdk/python/aleo_bridge/checkpoint.py | 6 + bridge-sdk/python/aleo_bridge/eth.py | 211 ++++++++++++++------ bridge-sdk/python/aleo_bridge/lifecycle.py | 33 ++- bridge-sdk/tests/conftest.py | 11 + bridge-sdk/tests/fakes/fake_web3.py | 11 +- bridge-sdk/tests/test_eth_connection.py | 49 ++++- bridge-sdk/tests/test_eth_recover.py | 40 +++- bridge-sdk/tests/test_eth_status.py | 74 ++++++- 9 files changed, 381 insertions(+), 79 deletions(-) diff --git a/bridge-sdk/README.md b/bridge-sdk/README.md index 17c059cd..41af13c7 100644 --- a/bridge-sdk/README.md +++ b/bridge-sdk/README.md @@ -251,16 +251,20 @@ Fees and nonces are filled defensively.

The load-balanced public RPC still answers eth_getTransactionByHash for the replaced dispatch — returning the transaction with blockNumber null, a stale mempool view — while eth_getTransactionReceipt is not-found and the account's latest nonce (85) has passed the dispatch's (83). The verdict required not-found on both probes, so the receipt stayed SOURCE_CONFIRMING and wait polled to its ceiling. A probe now counts as 'gone' when the node either does not know the hash OR returns it with no block number: both mean it is in no block, and together with a consumed nonce that is final — it can never be included. A transaction that comes back WITH a block number is mined and never dropped, however far behind its receipt read is.

A timeout is not a failure: the transfer is still in +flight, the exception carries the latest `progress`, and `wait` can be called +again. A source transaction that was dropped or replaced by the network before +it mined is reported as `failed` with an error stating that no funds moved; +`recover` then confirms from chain history that nothing landed and returns a +`resume` step for it. + +`resume` applies when work such as an ERC-20 approval succeeded but the +deposit itself was not submitted.

A receipt timeout returns a pending receipt, never a -failure. - -Fees and nonces are filled defensively. Public RPC endpoints answer -`eth_maxPriorityFeePerGas` with 0, and a zero-tip transaction can sit unmined -for hours, so every EIP-1559 tip is raised to a floor of 0.1 gwei -(`aleo_bridge.eth.MIN_PRIORITY_FEE_WEI`); pass -`Ethereum(..., min_priority_fee_wei=…)` or set `BRIDGE_MIN_PRIORITY_FEE_WEI` -(whole wei, read by `from_env`) to raise or lower it (`maxFeePerGas` stays -`2 * baseFeePerGas + tip`). The highest nonce broadcast for a -`(chain, sender)` is also remembered **per process** — not across processes or -machines — and never handed out again, because a load-balanced RPC can stop -reporting our own pending transaction and the next leg (typically a fresh -`Ethereum`) would then replace it. If a source transaction is dropped or -replaced anyway, it no longer waits forever: once two probes agree the hash is -in no block — the node either does not know it or still serves it with a null -`blockNumber`, which is what a load-balanced endpoint does for a replaced -transaction — and the account nonce has moved past the nonce it was sent at **as -seen by a node that has imported the block that consumed it**, and a final -re-read of the receipt still finds none, `source_status` returns `EXPIRED` with a -`sourceError` explaining that nothing moved, and its checkpoint is kept rather -than deleted so `recover()` can re-scan. A transaction that comes back with a -block number is mined, however far behind its receipt read is; so is one whose -receipt appears on that last re-read, and a probe whose own `nonce` or `from` -disagrees with the checkpoint yields no verdict at all. -`recover_source` takes that verdict first and then scans source history — a -dispatch that really landed wins — and hands back a resumable -`SOURCE_SUBMISSION_PENDING` when the scan ran, covered the head the verdict was -taken at, and found nothing; `resume()` then supersedes the dropped record with -the new transaction's. If a transfer was finished outside the SDK, its kept -dropped record stays listed in `pending()` until you clear it yourself with -`store.delete(checkpoint_id)` (the id is the source transaction hash). - -Live checks: `BRIDGE_LIVE_READS=1 ETHEREUM_RPC_URL=…` for read-only -mainnet quotes (`tests/live/test_eth_reads.py`); `BRIDGE_LIVE_FUNDS=1 -BRIDGE_LIVE_STATE_DIR=… SEPOLIA_RPC_URL=… EVM_PRIVATE_KEY=… -ALEO_E2E_PRIVATE_KEY=…` for the 2 USDC Sepolia leg -(`tests/live/test_eth_sepolia_leg1.py`). - -### Solana, directly +Binding a `FileCheckpointStore` to the client saves a checkpoint at every +submission boundary: after each approval, after an Aleo transaction is proved +but before it is broadcast, and after each broadcast.

Set `EVM_PRIVATE_KEY` through your existing secret-management +system. Public-to-private USDCx delivery needs no Aleo signer; the private +recipient example also needs `ALEO_PRIVATE_KEY` to claim, and its address must +match `--recipient`. + +For example, after reviewing the WBTC quote, use your recipient address: + +```sh +python examples/bridge_wbtc.py --recipient "$ALEO_RECIPIENT" --amount 0.001 --execute +``` + +`ALEO_RECIPIENT` here is your own shell variable containing a public address. +When executing, the script takes the Ethereum sender from `EVM_PRIVATE_KEY`. +It submits once, prints each journal ID, and monitors for up to 120 seconds. +Use `--timeout 600` to monitor longer. A timeout does not mean the deposit failed: +recover the existing transfer instead of running the submission command again. + +For USDC, choose `bridge_usdc_private_balance.py` for automatic private records, +or `bridge_usdc_private_recipient.py` to hide the Aleo address in the deposit. +Both default to 2 USDC. The Ethereum sender and deposited amount remain public. + +The private recipient example needs `BRIDGE_MINT_SECRET_NONCE`: a securely +generated, nonzero Aleo scalar retained in your secret store **before** sending. +`str(aleo.mainnet.Scalar.random())` generates such a value. Supply the same saved +value when recovering or claiming; the journal deliberately excludes it. +The script claims automatically if the deposit becomes ready during monitoring. + +RPCs default to public Ethereum, Solana, and Provable endpoints. Override +`ETHEREUM_RPC_URL`, `SOLANA_RPC_URL`, or `ALEO_RPC_URL` when needed; all three must +serve mainnet for these examples. Keys are read only by actions that need them. + +## Bridge out from Aleo + +Return assets to Ethereum or Solana to use them in applications on those chains. +Each outbound tutorial spends a **public Aleo balance** and needs Aleo credits +for fees. Hyperlane carries WBTC and SOL; private balances must be unshielded +before using these examples. xReserve redeems USDCx for USDC and deducts a +withdrawal fee from the amount received. Its quoted fee is an estimate. + +Review a quote with public addresses first.

To submit, set +`ALEO_PRIVATE_KEY` and add `--execute`; the signer supplies the Aleo sender. +No Ethereum or Solana private key is needed. The destination connection reads +the recipient's balance to monitor arrival. Avoid concurrent transfers to the +same recipient while monitoring: a balance increase alone cannot distinguish +this transfer from another payment. + +Delegated proving is the default. Pass `proving="local"` to `bridge.execute` +in the tutorial to prove on the application's machine instead. After submission, +retain the journal and use `recover_from_journal.py --action wait` if monitoring +times out. A timeout is not a reason to burn or send the source assets again. + +## Find and recover a transfer + +A journal lets you continue a transfer after closing the application. New +transfers have readable filenames, with a UTC date, daily counter, pair, and +amount: + +```text +2026-09-25_001_ethereum-wbtc_to_aleo-wbtc_0.001.json +``` + +The name stays fixed while the receipt and transaction IDs inside the JSON +change. `checkpoint.id` is the filename without `.json`. Counter allocation is +locked across processes and does not reuse numbers when completed checkpoints +are removed. Keep the hidden `.journal-counter` and `.journal.lock` metadata +when moving the journal. Independent journals can have matching names. + +List your journal locally to find the transfer: + +```sh +python examples/recover_from_journal.py +``` + +For a runnable status check without keys, this repository contains a checkpoint +reconstructed from an actual Solana transaction: + +```sh +python examples/recover_from_journal.py --journal examples/checkpoints \ + --id 2026-09-25_001_solana-sol_to_aleo-sol_676.2 +``` + +Its date records creation of this example journal entry, not the original +transaction date. It belongs to a historical transfer, not your account. +Status reads leave the example file unchanged. Existing receipt-named +checkpoints also remain supported. + +For your own transfer, pass its ID and use `--action wait` to monitor. If the +reported next step is `resume`, `--action resume` submits the unfinished source +step. If it is `complete`, `--action complete` claims private USDCx using +`ALEO_PRIVATE_KEY` and the original `BRIDGE_MINT_SECRET_NONCE`. These actions use +the existing transfer; neither calls `execute` again. + +If no files remain, get the confirmed WBTC bridge dispatch hash, original sender, +recipient, and amount from Ethereum history. Pass those values as +`--transaction`, `--sender`, `--recipient`, and `--amount` to +`recover_without_files.py`. It reconstructs recovery data in memory and reads +chain status without creating a journal. This example applies specifically to +confirmed Ethereum-to-Aleo Hyperlane WBTC transfers, not token approvals or +private USDCx deposits. A lost private claim nonce cannot be reconstructed from +public history. + +## Shield assets already on Aleo + +Shielding moves a public Aleo balance into a private record. Hyperlane delivers +public balances, so shielding is a separate step after delivery. xReserve can +deliver private USDCx directly, avoiding that extra conversion. + +Preview shielding 0.01 SOL already held on Aleo: + +```sh +python examples/shield_assets.py --asset aleo/sol --amount 0.01 +``` + +Set `ALEO_PRIVATE_KEY` and add `--execute` to submit using delegated proving. +Keep enough Aleo credits for the fee.

Cryptographic types are +also available directly for signing, record handling, and custom integrations. -- A **Web3.py-style facade** (`aleo.Aleo` / `aleo.AsyncAleo`) — a high-level, batteries-included client for connecting to a node, managing accounts, reading state, and building/proving/broadcasting transactions. -- **Low-level primitives** (`aleo.mainnet`, `aleo.testnet`) — direct Python bindings to Aleo's zero-knowledge cryptographic types, for when you need full control. +See the [SDK walkthrough](sdk/python/examples/facade_quickstart.py) for account +and program examples, and the [bridge tutorials](bridge-sdk/examples/README.md) +for transfers to and from Aleo, shielding, and recovery. -Built with snarkvm 4.9.1 (MainnetV0).

Reading public data needs only an address. Sending funds also +requires the private key for the account holding those funds. -**MCP clients (Claude Desktop, etc.):** +This setup connects to mainnet and imports an existing account from the +application's environment. Keep the key in the application's secret store; +never paste it into documentation, logs, or an agent conversation. -```bash -pip install "shield-swap-sdk[mcp]" -python -m aleo_shield_swap.mcp # stdio server with the lifecycle tools +```python +import os +from aleo import Aleo, HTTPProvider + +aleo = Aleo(HTTPProvider("https://edge.provable.com/api", network="mainnet")) +account = aleo.account.from_private_key(os.environ["ALEO_PRIVATE_KEY"]) +aleo.default_account = account +address = str(account.address) +print(address) # The public aleo1… address used to receive funds. ``` -## Bridging (move assets between Ethereum, Solana and Aleo) +For a new account, use `aleo.account.create()` instead of importing a key. +Retain the new account's private key securely before receiving funds; creating +another account later does not restore access to the first one. + +The following synchronous examples continue this setup. Each submission example +spends real funds on the configured network. Alternative proving methods are +separate choices, not consecutive steps for the same transfer. + +## Read balances and program state -The [`bridge-sdk`](./bridge-sdk) package (`pip install aleo-bridge-sdk`, -import `aleo_bridge`) moves ETH, WBTC, USDT and SOL over Hyperlane and USDC -over Circle xReserve, into Aleo and back out, with the same verb structure -as the facade. A checkpoint saved at every submission lets an interrupted -transfer be finished rather than sent twice. +Check a public balance before deciding how much to send, leaving enough for any +fee paid by the account. Public credits are visible on-chain; this balance does +not include credits held in private records. ```python -from aleo_bridge import Bridge, Ethereum +microcredits = aleo.get_balance(address) +print(aleo.from_microcredits(microcredits), "credits") +# 1,500,000 microcredits are 1.5 credits; an unfunded address returns 0. +``` + +Programs can also store public values in mappings, which associate a key with a +value. For example, the credits program's `account` mapping holds public credit +balances: -bridge = Bridge(aleo, ethereum=Ethereum(ethereum_rpc_url, private_key=evm_private_key)) -quote = bridge.quote(source_chain="ethereum", source_asset="usdc", destination_chain="aleo", - amount="5", recipient=bridge.aleo_address()) -progress = bridge.wait(bridge.execute(quote.plan)) # approval + deposit, then poll to done / resume / complete +```python +credits = aleo.programs.get("credits.aleo") +value = credits.mapping("account").get(address) +print(value) # The mapping value returned by the node. ``` -Agents get the same surface through `python -m aleo_bridge` (the generated -guide), `aleo_bridge.agent.bridge_tools()`, and the stdio MCP server -`python -m aleo_bridge.mcp`; every write is confirm-gated and shows fees -before anything moves. See [bridge-sdk/README.md](./bridge-sdk/README.md) -for routes, connections, recovery and the live test suite. +Use integer microcredits for credit amounts: **1 credit = 1,000,000 +microcredits**. For conversion from display units, pass an exact decimal string, +such as `aleo.to_microcredits("1.5")`, instead of a floating-point amount. -## Quick Start (facade) +## Send credits -```python -from aleo import Aleo +A public transfer makes credits available at another Aleo address. The sender, +recipient, and amount are public. Start by preparing the recipient and amount, +inspect the intended operation, then choose how to prove and submit it. -# Connect (construction is offline — no I/O until you make a call) -aleo = Aleo(Aleo.HTTPProvider("https://edge.provable.com/api")) -print(aleo.network_name) # "mainnet" -print(aleo.network_id) # 0 +### Prepare and inspect the transfer -# Create an account (local) -account = aleo.account.create() -print(account.address) # aleo1… +A program call describes the operation to perform. Preparing it does not send +funds. This example prepares a transfer of one credit to an illustrative public +address; replace it with the intended recipient before submitting. -# Read a public balance # requires a live node -balance = aleo.get_balance(str(account.address)) -print(aleo.from_microcredits(balance), "credits") -``` +```python +recipient = "aleo1rs6fdxg703s3em27uhxsehhfd8znaly22jt6upggrxc77q8d9yfq33pk28" +amount = 1_000_000 # One credit, in microcredits. +credits = aleo.programs.get("credits.aleo") +call = credits.functions.transfer_public(recipient, amount) -`Aleo.HTTPProvider` is also importable directly as `from aleo import HTTPProvider`; the two are equivalent. +print(call.signature) # transfer_public(address, u64) +print(call.args) # Recipient address and amount encoded for the program. +authorization = call.simulate(account) +print(authorization.decoded()) # Inspect the authorized inputs and outputs. +``` -## The verb ladder (sync) +Simulation signs an authorization locally without generating a proof or +broadcasting a transaction. It does not reserve funds or guarantee that the +network will accept the eventual transaction. -The facade follows a clean top-to-bottom narrative: **connect → account → read → build a call → inspect → send**. Each rung does a little more than the one above it. +Other deployed programs use the same pattern: load the program with +`aleo.programs.get("program_name.aleo")`, then select a function through +`program.functions`. `list(credits.functions)` lists the available functions. -### 1. Connect +### Choose where to generate the proof -```python -from aleo import Aleo +Every Aleo transaction needs a cryptographic proof. Delegated proving avoids +performing that computation on the application's machine. The proving service +receives the transaction contents, while the private key stays with the +application. By default, `delegate` requests that the service's fee-paying +account cover the transaction fee. -aleo = Aleo(Aleo.HTTPProvider("https://edge.provable.com/api")) +To submit the prepared transfer through delegated proving: -# Optional: check reachability # requires a live node -if aleo.is_connected(): - print("connected to", aleo.network_name) +```python +result = call.delegate(account) # Requests proving and broadcast by the service. +# Retain the service response and its transaction ID to check confirmation. ``` -`HTTPProvider` is a *config object*, not a live connection — it is safe to construct without a network. It accepts `network=` (`"mainnet"` / `"testnet"`), `api_key=`, `prover_uri=` (the DPS endpoint), `headers=`, and a custom `transport=` callable. +The default `https://edge.provable.com/api` service does not require API +credentials. Credentialed deployments, such as `https://api.provable.com`, +require their own API key and consumer ID. + +For transaction contents that should stay out of the proving service, generate +the proof locally instead. This uses the application's CPU and may download +proving parameters. The account pays a public transaction fee by default. -### 2. Account — create or import (local) +Run this **instead of** the delegated submission above: ```python -# Fresh random account -account = aleo.account.create() +tx_id = call.transact(account) # Proves locally and broadcasts once. +print(tx_id) # Save this at1… transaction ID before waiting for confirmation. +``` -# Import from a private-key string (or a PrivateKey object) -account = aleo.account.from_private_key("APrivateKey1zkp…") +To inspect a proven transaction before broadcasting, use +`call.build_transaction(account)`. Fee choices and private fee records are +covered under [Account, privacy, and proving options](#account-privacy-and-proving-options). -# Derive deterministically from a field seed -account = aleo.account.from_seed("123field") +### Confirm delivery -# Sign / verify (bytes) -sig = aleo.account.sign(b"hello aleo", account) -assert aleo.account.verify(str(account.address), b"hello aleo", sig) +Submission and confirmation are separate steps. Retain the transaction ID so +monitoring can continue if the application closes or a request times out. +This example continues the local submission above: -# Sign / verify a typed Aleo value -sv = aleo.account.sign_value("100u64", account) -assert aleo.account.verify_value(str(account.address), "100u64", sv) +```python +from aleo import TransactionConfirmationTimeout + +try: + confirmed = aleo.network.wait_for_transaction(tx_id, timeout=60.0) +except TransactionConfirmationTimeout: + print("Still unconfirmed; check this transaction again:", tx_id) +else: + print("Confirmed:", tx_id) ``` -Set `aleo.default_account = account` and the verbs below will use it whenever you omit the signer. +**Do not send the transfer again because monitoring timed out.** Check the +existing transaction with `aleo.network.get_confirmed_transaction(tx_id)` or +continue waiting with the same ID. If the submission response was lost, inspect +account transaction history before trying another submission. Rejected +transactions can still incur fees. + +## Use private credits + +Private credits are held in encrypted records, analogous to Bitcoin's UTXOs. +A private transfer spends an unspent record and creates records for the +recipient and any change. The input record must cover the amount being sent. -> **Note:** the facade deliberately has no "recover signer from signature" verb. Aleo is a privacy chain — surfacing "which address signed this?" is a de-anonymisation vector. The low-level `Signature.to_address()` primitive remains available directly if you truly need it. +Use private transfers when balances and transfer details should not be publicly +readable. Finding spendable records is a separate choice from proving a +transaction: the default hosted scanner needs the account's view key, which +lets that service decrypt its records. A view key cannot spend the funds. -### 3. Read — balance and mappings +The following example assumes the configured account already has a private +credits record. It registers the account for scanning, selects a record covering +one credit, and submits a private transfer through delegated proving: ```python -# Public credits balance in microcredits (0 if the address is unfunded) # requires a live node -micro = aleo.get_balance(str(account.address)) -print(aleo.from_microcredits(micro), "credits") +registration = aleo.records.register(account) # Shares the view key with the scanner. +if not registration.get("ok"): + raise RuntimeError("Record scanner registration failed; no transfer was submitted.") + +record = aleo.records.get_unspent_credits_record(min_microcredits=1_000_000) +if record is None: + raise RuntimeError("No suitable record found; check funds and scanner progress.") -# Read any on-chain mapping through a bound Program # requires a live node credits = aleo.programs.get("credits.aleo") -raw = credits.mapping("account").get(str(account.address)) -print("account mapping value:", raw) +private_call = credits.functions.transfer_private(record, recipient, 1_000_000) +result = private_call.delegate(account) # The prover can read this transaction's contents. ``` -Unit helpers are local: `aleo.to_microcredits(1.5) == 1_500_000` and `aleo.from_microcredits(1_500_000) == 1.5`. Address validation is local too: `aleo.is_valid_address(s) -> bool`. +A missing record can mean that scanning has not caught up, that funds are +already spent, or that no single record covers the amount. It does not establish +that the account has no private funds. -### 4. Build a call +To create a private balance from public credits, use +`credits.functions.transfer_public_to_private(address, 1_000_000)` and submit +with one of the proving methods above. Wait for confirmation and scanner +indexing before trying to spend the new record. The source public balance change +remains visible. -`aleo.programs.get(...)` fetches a program and exposes its transitions as `program.functions.`, mirroring web3.py's ABI-driven `contract.functions`. Calling one **coerces your Python arguments to Aleo values** and returns a `BoundCall`: +To avoid sharing a view key with the hosted scanner, supply an unspent record +already held by the application, or assign a custom `RecordProvider` to +`aleo.record_provider`. Choose local proving separately if transaction contents +must also stay out of the proving service. -```python -# requires a live node (to fetch the program source) -credits = aleo.programs.get("credits.aleo") +## Bridge assets -call = credits.functions.transfer_public(str(account.address), 1_000_000) -print(call.signature) # "transfer_public(address, u64)" -print(call.args) # ['aleo1…', '1000000u64'] — coerced +Bring assets from Ethereum or Solana to Aleo for use in Aleo applications, or +withdraw them back to their source chain. Hyperlane carries ETH, WBTC, USDT, +and SOL; Circle xReserve connects Ethereum USDC with Aleo USDCx. + +The [Bridge SDK guide](bridge-sdk/README.md) covers supported pairs, costs, +public and private delivery, and recovery after an interruption. Its +[runnable tutorials](bridge-sdk/examples/README.md) show transfers in both +directions with explicit quotes, submission steps, and progress checks. + +```sh +python -m pip install aleo-bridge-sdk ``` -You can also list/iterate the available functions: `list(credits.functions)`, `"transfer_public" in credits.functions`. +Keep a bridge journal when submitting transfers. It identifies the existing +transfer and completed work so an interruption can be recovered without sending +the funds again. -### 5. Inspect — `simulate` / `.decoded()` +## Swap assets and manage liquidity -Before proving or broadcasting anything, build the **authorization locally** and look at what the call will produce. This is a proof-free, network-free dry run: +Use the Shield Swap SDK to trade assets privately on Aleo, provide liquidity, +and collect earnings. The [Shield Swap guide](shield-swap-sdk/README.md) +covers account setup, pool selection, quotes, and transaction workflows. -```python -auth = call.simulate(account) # alias of .authorize(); .call() also works -print(auth.outputs) # per-transition output lists -print(auth.decoded()) # [{program, function, inputs, outputs}, …] +```sh +python -m pip install shield-swap-sdk ``` -Both `AuthorizationResult` and `TransactionResult` expose the same `.outputs` / `.decoded()` surface, plus a `.raw` escape hatch to the underlying network object. You can also decode after the fact with `aleo.decode_transition(tx_id_or_transition)`. +## Use an agent -### 6. Transact — full prove + broadcast +An agent can help find supported assets, compare transfer costs, prepare a swap, +or check whether a transaction completed. The Bridge and Shield Swap packages +provide guides and tools for these tasks. Choose a guide for a coding agent +working in a project, or MCP for an application that connects to tool servers. -`build_transaction` (alias `prove`) runs the whole ladder locally: authorize → execute → prepare trace → prove execution → authorize+prove fee → assemble. `transact` does that **and** broadcasts, returning the transaction id: +### Give a coding agent the package guide -```python -# requires a live node + funded private key -tx_id = credits.functions.transfer_public( - str(account.address), 100 -).transact(account) +Install the package needed for the task, then ask the agent to read its generated +guide. These commands print the available operations and how to use them; they +do not submit transactions: -confirmed = aleo.network.wait_for_transaction(tx_id, timeout=60.0) +```sh +python -m aleo_shield_swap # Account, swap, and liquidity instructions. +python -m aleo_bridge # Route, quote, transfer, and recovery instructions. ``` -Fees are **public by default** (base cost from the execution). Pass `priority_fee=` for a tip, or opt into a **private fee** with `private_fee=True` (auto-sourced from `aleo.record_provider`) or by passing an explicit `fee_record=`. +Keep existing project instructions when adding these guides; redirecting output +to an existing `AGENTS.md` would replace that file. Configure private keys through +the application's environment or secret store, rather than through chat. -### 7. Delegate — the flagship path (fee master pays by default) +Start with a concrete request, such as “Quote a transfer of 5 USDC from Ethereum +to USDCx on Aleo” or “Show the available Shield Swap pools.” Include the intended +network, accounts, and amount when relevant. Review the quote before authorizing +a transaction, and retain its transaction ID or bridge journal for recovery. -`delegate` hands proving to a **Delegated Proving Service (DPS)**: you build only the lightweight main authorization locally, and the DPS does the expensive SNARK proving. By default **the prover's fee master pays the fee** — no records, no public fee, no friction. That frictionlessness is the whole point. +### Connect an MCP client -```python -# requires prover credentials; fee master pays -result = credits.functions.transfer_public( - str(account.address), 100 -).delegate(account) +MCP lets an agent application call the package's tools through a local process. +Install the extra for the required package: + +```sh +python -m pip install 'shield-swap-sdk[mcp]' 'aleo-bridge-sdk[mcp]' ``` -Want to pay your own fee instead? `delegate(account, pay_own_fee=True)` (public) or `delegate(account, fee_record=)` (private). Both bind the fee to the real execution id, so they prove the execution locally first. `broadcast=False` returns the proven transaction without submitting it. +Use `python -m aleo_shield_swap.mcp` or `python -m aleo_bridge.mcp` as the server +command. The package guides explain which tools read data and which submit +transactions, including their confirmation requirements. -### Private transfers — delegated proving + record discovery +### Limit access to read operations -A full private transfer combines the two trust-minimising paths: **delegated proving** (the prover's fee master pays) and a **record provider** to discover the private records you own. The default record provider (`aleo.records`) uses Provable's hosted scanner — registering shares your view key with that service so it can index your records. If you'd rather not share a view key, assign your own `RecordProvider` instead. +For a bridge assistant that should only inspect routes, quotes, and progress, +expose the read-only tool definitions: ```python -# requires prover credentials + hosted-scanner registration -credits = aleo.programs.get("credits.aleo") +from aleo_bridge import bridge_tools -# 1) Move public credits into a private record (delegated — fee master pays) -credits.functions.transfer_public_to_private(str(account.address), 100_000) \ - .delegate(account) +tools = bridge_tools(include_writes=False) +# Supply these definitions to the application's agent integration. +``` -# 2) Register with the record provider and find the new private record -aleo.records.register(account) # shares the view key with the scanner -record = aleo.records.get_unspent_credits_record() +When bridge submission tools are enabled, they require `confirm: true` before +moving funds. Without it, they return the quote or pending action for review. +The application should obtain the caller's authorization before supplying that +flag; a tool argument does not establish human approval by itself. -# 3) Spend the private record with a private transfer (delegated) -credits.functions.transfer_private(record, str(recipient.address), 1) \ - .delegate(account) -``` +## Make concurrent network requests -`aleo.record_provider` is swappable: set it to your own object implementing the `RecordProvider` protocol (`get_unspent_credits_record` / `find`), and the whole facade (including private-fee auto-sourcing) uses it, with no view-key sharing. +Use `AsyncAleo` when an application needs to wait on network requests without +blocking other work. Install the async extra, then await network reads and +transaction submissions. Account creation, signing, and preparing a call remain +synchronous. -## Async (`AsyncAleo`) +```sh +python -m pip install 'aleo-sdk[async]' +``` -The async facade mirrors the sync surface. Construction and the local, CPU-bound steps stay synchronous; everything that touches the network is awaitable. +This standalone example reads two public balances concurrently without loading +keys or submitting transactions: ```python import asyncio -from aleo import AsyncAleo +from aleo import AsyncAleo, HTTPProvider async def main(): - aleo = AsyncAleo(AsyncAleo.HTTPProvider("https://edge.provable.com/api")) - print(aleo.network_name) # sync — no I/O + aleo = AsyncAleo(HTTPProvider("https://edge.provable.com/api", network="mainnet")) + accounts = [aleo.account.create(), aleo.account.create()] + balances = await asyncio.gather( + *(aleo.get_balance(str(account.address)) for account in accounts) + ) + for account, balance in zip(accounts, balances): + print(account.address, aleo.from_microcredits(balance), "credits") + # Newly created accounts normally have no funds. - # Account ops are sync (purely local), even on AsyncAleo - account = aleo.account.create() - sig = aleo.account.sign(b"hi", account) - assert aleo.account.verify(str(account.address), b"hi", sig) +asyncio.run(main()) +``` - # Reads are awaited # requires a live node - micro = await aleo.get_balance(str(account.address)) - print(aleo.from_microcredits(micro), "credits") +Fetching a program uses `await aleo.programs.get(...)`. Preparing its call and +running `call.simulate(account)` stay synchronous. Choose either +`await call.delegate(account)` or `await call.transact(account)` to submit a +transfer; do not run both for the same intended payment. - # Build a call — fetching the program is awaited # requires a live node - credits = await aleo.programs.get("credits.aleo") - call = credits.functions.transfer_public(str(account.address), 100) +## Test without spending mainnet funds - # authorize / simulate / call are SYNC (local proof-free build) - auth = call.simulate(account) - print(auth.decoded()) +Use a local development node to test transactions with prefunded development +accounts.

Heavy proving runs in `asyncio.to_thread` so it does not block the event loop. +Development accounts are deterministic test fixtures; never use their keys to +hold real funds. `node.snapshot()` captures the node's current chain state. -## Testing utilities (`aleo.testing`) +For SDK development, see the [build instructions](sdk/Readme.md).

Add `priority_fee=` in microcredits +for an additional fee, or use `private_fee=True` to select a private fee record +through `aleo.record_provider`. An explicit `fee_record=` uses the supplied +credits record instead. -The `-m devnode` tests additionally require the `aleo-devnode` binary (see `Devnode` above). +Delegated proving requests service-paid fees by default.
