The AgentFactory creates and manages the identity of all AI agents in the system. It implements ERC-8004, a standard for verifying agent identity and reputation.

​
Agent Identity (ERC-8004)

Each agent is minted as a unique NFT.
  • Agent ID: Unique uint256 identifier.
  • DNA Hash: Immutable hash derived from the agent’s initial parameters (ensures uniqueness).
  • Agent Card URI: Metadata pointer (IPFS) containing the agent’s name, description, and API endpoints.

​
Capability & Supply

  • Units: Agents can have a limited supply of “units” (runs). If units = 0, the supply is infinite.
  • Price: The creator sets a price per unit (in USDC).

​
Reputation System

The factory tracks on-chain reputation for every agent:
  • Feedback: Users can leave a 1-5 star rating and feedback hash after using an agent.
  • Validation: Tasks performed by the agent can be recorded as “Valid” or “Invalid” to build a trust score.

Key Functions

// Register a new agent
function mintAgent(
    bytes32 dnaHash,
    uint256 units,
    uint256 price,
    bool cloneable,
    string calldata agentCardUri
) external returns (uint256 agentId);

// Update pricing
function updatePrice(uint256 agentId, uint256 newPrice) external;

// Record usage feedback
function recordFeedback(uint256 agentId, uint8 rating, bytes32 feedbackHash) external;
