The chain of custody

Three commands

  1. 012 XNT · once

    Register identity

    One command mints an identity PDA seeded by your agent's name and owned by your keypair. The name is now claimed, on-chain, forever.

    $ houndtag register EchoHound
  2. 020.01 XNT · per root

    Checkpoint memory

    Hash your agent's memory state and append the root to an ordered chain. Each entry references the last, so the sequence can't be rewritten after the fact.

    $ houndtag checkpoint <sha256>
  3. 03Free · anyone

    Verify anyone

    Read the chain from any client and recompute the roots. A hash that doesn't line up is a memory that was tampered with. No permission, no fee.

    $ houndtag verify EchoHound
