From 4a52381ae22d312b98dadc7382ef51dc52a4da51 Mon Sep 17 00:00:00 2001 From: markankamaransheogarat-sys <279850453+markankamaransheogarat-sys@users.noreply.github.com> Date: Mon, 19 Oct 2026 14:26:07 +0000 Subject: [PATCH 1/2] feat(contract): implement anti-frontrunning commit-reveal mechanism for competitive payroll bounties (#212) - Add BountyData and BountyCommitment contract types for competitive task escrows - Add DataKey variants: NextBountyId, Bounty(u64), BountyCommitment(u64, Address) - Implement create_bounty to escrow reward tokens against a target solution hash - Implement commit_bounty_claim storing commitment hash binding claimant address, proof, and secret salt - Enforce BOUNTY_CHALLENGE_DELAY_LEDGERS (5 ledgers) delay window to eliminate mempool copy-paste frontrunning - Implement reveal_bounty_claim to verify preimage, validate solution hash, and dispatch payout to claimant - Implement reclaim_bounty for creator recovery of expired unclaimed bounties - Add public getters get_bounty, get_bounty_commitment, and pure helper compute_bounty_commitment_hash - Implement comprehensive unit test suite in test.rs covering happy path, early reveal rejection, frontrunning resistance, tampered preimages, invalid solutions, double-claim protection, and expired reclaim - Fix baseline test delimiters and lending pool client address call so all 134 soroban tests pass cleanly --- contracts/soroban/src/lib.rs | 301 ++++++++++++++++++- contracts/soroban/src/test.rs | 551 ++++++++++++++++++++++------------ 2 files changed, 650 insertions(+), 202 deletions(-) diff --git a/contracts/soroban/src/lib.rs b/contracts/soroban/src/lib.rs index 1236019..92a8bb6 100644 --- a/contracts/soroban/src/lib.rs +++ b/contracts/soroban/src/lib.rs @@ -54,6 +54,9 @@ pub const MAX_OVERDRAFT_PERCENTAGE: u32 = 20; /// Challenge period between recovery initiation and execution. pub const RECOVERY_TIMELOCK_SECONDS: u64 = 14 * 24 * 60 * 60; +/// Minimum ledgers (~25 seconds) that must pass between commit and reveal (#212) +pub const BOUNTY_CHALLENGE_DELAY_LEDGERS: u32 = 5; + /// Calculates (threshold, extend_to) in ledgers for vault persistent storage /// and contract instance storage based on interval_seconds. pub fn calculate_ttl_params(interval_seconds: u64) -> (u32, u32) { @@ -188,6 +191,30 @@ pub struct MerklePayrollData { pub expiration_timestamp: u64, } +/// Competitive payroll bounty data (#212): escrows reward tokens for tasks solved on-chain. +#[contracttype] +#[derive(Clone, Debug, Eq, PartialEq)] +pub struct BountyData { + pub id: u64, + pub creator: Address, + pub token: Address, + pub amount: i128, + pub solution_hash: BytesN<32>, + pub expiration_timestamp: u64, + pub claimed: bool, + pub claimant: Option
