Agents need to prove who they are and what they're allowed to do. .agentauth is the namespace for the auth layer of the agentic era — keys, scopes, delegation, and consent.
Own the entire .agentauth namespace. SLD registration returns at a later date.
Handshake is a decentralized, permissionless naming protocol — there's no ICANN, no registrar middlemen. Your SLD is truly yours.
