Circle Agent Passport
Every agent transacting on Circle Gateway needs an identity that can be checked. The Hive Agent Passport ties the agent's DID, capabilities, creator wallet, spending limits, and reputation into one signed artifact on the RogueWave-Lattice v2 substrate. The wallet checks the passport before any money moves. No passport, no nanopayment.
How it plugs in.

What Circle gets.
- Fraud protection right at the wallet layer. No valid passport means no payment leaves the wallet.
- A procurement-grade pitch: every agent in the Marketplace can be checked cryptographically.
- KYA (Know Your Agent) becomes a Circle-recognized attestation, not a vendor checklist.
- Each passport carries an ML-KEM-768 public key, so agents can do a forward-secret handshake with each other out of the box.
Ready when Circle is.
