- Developers checking preset account or transaction thresholds
- Worth noticing
- The service says its single-party ceremony makes proofs forgeable until three independent parties participate.
Field notes
The documented flow uses a single-use nonce and rejects replaying it, while payment is attached to the verification request through x402 on Base. The page says issued tokens and counters are held in memory and cleared on restart. It also states that the ceremony parameters were generated locally, that buyers cannot rebuild the chain, and that the circuits have not received an external audit.
