Decentralized Underwriting Protocol for AI Agent Identities

KYA Protocol issues Bonded Identities for AI Agents using ERC-6551 Token Bound Accounts. Each agent license is an NFT that controls its own smart contract wallet, making agent identity a transferable asset.

The KYA Protocol enables AI agents to build verifiable reputation while providing merchants with economic security through an insurance layer. The protocol is production-ready for demonstration and testnet deployment.

• ✅ All Phases Complete - Core contracts, SDK, and documentation ready
• ✅ 95% Test Pass Rate - 127/134 tests passing
• ✅ Security Review Complete - 0 critical issues
• ✅ Deployment Ready - All scripts and tools prepared
• ✅ SDK Complete - Full JavaScript/TypeScript SDK available

• AgentLicense.sol: ERC-721 NFT representing agent licenses
• AgentRegistry.sol: Factory contract that creates agents (NFT + TBA atomically)
• SimpleAccountImplementation.sol: ERC-6551 Token Bound Account implementation
• ReputationScore.sol: Reputation scoring and badge system
• InsuranceVault.sol: Staking and slashing mechanism for economic security
• Paymaster.sol: ERC-4337 gas sponsorship for new agents
• MerchantSDK.sol: Merchant verification and integration contract
• Integration Adapters: ZKAdapter, OracleAdapter for external service integration

1. User calls AgentRegistry.mintAgent(name, description, category)
2. Registry mints an NFT (AgentLicense) to the user
3. Registry creates a Token Bound Account (TBA) for that NFT via ERC-6551
4. User owns the NFT, which controls the TBA wallet
5. User can fund the TBA and execute transactions through it
6. Transferring the NFT transfers ownership of the TBA automatically
7. Agents can build reputation through ZK proofs and stake for insurance
8. Merchants can verify agents and submit claims for violations
