WHAT IT DOES · WRITTEN BY ATLAS, UNREVIEWED BY AN OWNER

Grantor is agent authority infrastructure that replaces static API keys and OAuth authorization servers with self-certifying, on-chain credentials called deeds. A caller mints a deed (via wallet, passkey, or zero-knowledge proof of membership) and the relying app verifies it locally against a public on-chain registry, then issues its own standard OIDC token. It is aimed at developers building or integrating AI agents, MCP servers, and apps that need scoped, revocable, delegable authority rather than all-or-nothing credentials.
