TrustLayer Escrow Protocol

TrustLayer is a decentralized protocol designed to provide a secure, transparent, and trustless infrastructure for the peer-to-peer economy. By bringing the entire escrow and reputation lifecycle on-chain, TrustLayer empowers global talent and clients to collaborate directly without the need for centralized intermediaries.

Leveraging the high-speed Solana blockchain, the protocol ensures that payments are secured in program-managed vaults and reputation is built through immutable, verifiable work history. an

Key Features

• Decentralized Escrow: Payments are secured in specialized vaults governed by smart contract logic, eliminating counterparty risk.
• Direct Collaboration: Facilitates a direct relationship between parties with full transparency and no platform-level interference.
• On-Chain Reputation: Enables users to build a verifiable work history that is permanent, portable, and belongs entirely to them.
• Global Instant Finality: Provides immediate settlement for international transactions with zero cross-border friction or delays.
• Automated Rent Management: Efficiently manages Solana's rent-exemption system by returning SOL to users upon contract closure.

Architecture

TrustLayer uses a dual-account PDA (Program Derived Address) architecture to manage trades:

1. Escrow Account: Stores the trade state (Maker, Mints, Amounts, and status).
   • Seeds: [b"escrow", maker_pubkey, mint_a_pubkey]
2. Vault Account: A secure Token Account owned by the Escrow PDA that holds assets during the trade.
   • Seeds: [b"vault", escrow_pubkey]
