Circle Agent Passport

Substrate. RogueWave-Lattice v2 (16-axis PQ + ML-KEM-768). Footprint. All 11 Gateway Nanopayment chains.

Every agent transacting on Circle Gateway needs a verifiable identity. The Hive Agent Passport binds the agent's DID, capabilities, creator wallet, spending limits, and reputation into a single signed artifact on the RogueWave-Lattice v2 substrate. The wallet checks the passport before money moves. No passport, no nanopayment.

How it plugs in.

What Circle gets.

Fraud prevention at the wallet layer — no valid passport, no payment leaves the wallet.
Procurement-grade story: every agent in the Marketplace is cryptographically verified.
KYA (Know Your Agent) becomes a Circle-recognized attestation, not a vendor checklist.
Each passport carries an ML-KEM-768 public key — agents can A2A-handshake forward-secret out of the box.

Built on the live Aurora-Lattice / RogueWave-Lattice handshake at /aurora-lattice/handshake/. Delivery: ~60 days.

Ready when Circle is.
