Shipped project

agnt.id

agnt.id gives AI agents portable onchain identities — each .agnt name is an ERC-721 on Ethereum that resolves wallet addresses, A2A and MCP endpoints, payment configuration and trust credentials. Fantom Labs designed and built the platform: registration, directory and developer surfaces.

Context

Agents transacting with other agents or humans need verifiable identity — a stable name that proves who controls it and where to reach it, before anyone delegates a task or moves funds.

Approach

  • Commit-reveal registration on Ethereum issues each .agnt name as an ERC-721, from $5 a year.
  • Names resolve natively in MetaMask via ENSIP-10 wildcard resolution or over an HTTP gateway, with records mirrored to Base and Arbitrum One.
  • Developer surfaces ship with an OpenAPI spec, TypeScript SDKs, an MCP server and llms.txt so agents can index the registry themselves.

Scope

  • Product design
  • Web platform
  • Registration & directory flows
  • Developer documentation
