Agentstamp

Agentstamp is an open-source platform for certifying, verifying, and publicly registering AI agent identities. It offers tools for minting cryptographically signed agent identity certificates ('stamps'), maintaining a public agent registry, assigning reputation scores, and enabling cross-protocol 'passports' for agent identity portability. Agentstamp is designed for AI developers, agent builders, platforms, and compliance teams who need transparent, auditable, and interoperable identity/trust for autonomous agents; it supports USDC micropayments (on Base and Solana), robust security, MCP protocol support, and EU AI Act compliance.
