Technical Reference

This section provides a deep technical reference of the SynArc protocol architecture, transaction flows, security controls, and on-chain specifications.

Protocol Architecture

SynArc is designed as a modular, stablecoin-native governance layer on the Arc network. It decouples long-term asset management (Timelocked Treasury Vaults) from short-term operations (AI Agent Executors).

Core Security Principles

1. Gated Executions: Deployed AI agent contracts (SynArcAgent.sol) delegate task executions to hot keys but route asset withdrawal and major treasury updates through timelocked multi-sig transactions.
2. Deterministic Governance: Custom proposal templates are validated on-chain to prevent malicious state manipulation.
3. Reputation Registry: The ERC-8004 Registry incorporates a decentralized peer vouching system where agents can be penalized or rewarded based on execution accuracy.

ERC-8004 Identity Registry

The ERC-8004 standard defines how autonomous agents advertise their identity, owner, capabilities, and dynamic reputation index.

Interface Specification

interface IERC8004 {
    event AgentRegistered(address indexed agentAddress, address indexed owner, string name);
    event ReputationUpdated(address indexed agentAddress, uint8 newReputation);

    function registerAgent(string calldata name, string[] calldata capabilities, string calldata metadataUri) external;
    function vouch(address agentAddress) external;
    function disavow(address agentAddress) external;
    function getAgent(address agentAddress) external view returns (
        address owner,
        string memory name,
        string[] memory capabilities,
        string memory metadataUri,
        uint8 reputationIndex
    );
}

Treasury Escrow Flow

SynArc's Crowdfunding mechanism protects contributors by holding funds in campaign-specific escrows (SynArcCrowdfund.sol) that release tokens based on milestone approvals.

1. Campaign Creation: Creator deploys a SynArcCrowdfund contract.
2. Capital Contribution: Backers deposit USDC or EURC into the escrow.
3. Milestone Locks: Funds are partitioned into milestones (e.g., 30% / 40% / 30%).
4. Milestone Verification: The creator requests a release, triggering a DAO proposal.
5. Release / Refund: If the proposal passes, the milestone funds release to the creator. If the milestone fails, backers can trigger refund claims for the remaining escrow balance.
