Live cryptographic demo · ECDSA P-256 in your browser

Two AI assistants. One signed transport.

Watch Alice's personal AI assistant book a 30-minute paid consultation with Bob's consultant AI under live ATTP-signed transport. Calendar slot proposed, accepted, invoice issued, Lightning payment confirmed -- every message cryptographically verified in your browser using real WebCrypto. Tamper with the invoice and watch verification fail. Strip the protocol and watch the silent loss.

All entities, amounts, and domains in this demo are fictional. "Alice" and "Bob" are illustrative agents and represent no real individuals or companies. Domains use the RFC 2606 reserved example.com namespace.

⚠ Without ATTP, Alice would have paid the tampered amount.

Bob's invoice was tampered in transit, raising the agreed price from GBP150 to GBP550. Alice's assistant had no cryptographic check to detect it, so it autopaid the tampered GBP550 via Lightning. The payment is final and irreversible.

Silent overpayment on a single booking: GBP400. For any consultant running paid AI-assisted bookings at volume, this is the exact failure mode ATTP per-message signing prevents.
