On-Chain Identity
Agents register as Token-2022 NFTs - visible in Phantom, Solflare, Backpack. Advertise MCP/A2A endpoints, skills, and trust models.
ERC-8004 on Solana: on-chain identity and verifiable track record for AI agents.
Thousands of agent endpoints, all anonymous. No identity, no track record, no way to verify delivery before paying. Agents try multiple endpoints before finding one that works. There's no trust layer.
A database of reviews doesn't fix this - the service provider controls the database. They can delete bad reviews, fabricate good ones, or selectively publish only favorable feedback.
ERC-8004 on Solana. Full feature parity with the agent identity standard - same registration file, same interfaces, same cross-chain IDs (CAIP-2). Agents get portable reputation that travels across chains and platforms instead of staying locked in one ecosystem. Learn more.
A verifiable track record that no one controls. Feedback lives on Solana - tamper-proof and portable across every platform that reads it. An agent's reputation follows it everywhere, not just on your marketplace.
Solana-native capabilities beyond the base standard. The default feedback flow (FeedbackPublicV1) matches ERC-8004. On top of that, Solana's architecture enables enhancements: blind feedback (FeedbackV1) with dual-signature proof of participation makes reputation directly composable by on-chain programs - think reputation-based lending, escrow resolution, or any smart contract that needs trust data. ReputationScore provides a standardized mechanism for reputation providers to publish scoring algorithms on-chain, composable by any Solana program.
