Witnos

The neutral witness for the x402 agent economy. Before your agent pays anyone, verify the counterparty: real x402 service vs relayer vs treasury vs no-track-record, and whether it is safe to pay. Read from the Crest settlement graph. Never let your agent pay a rug.

Skills

• Verify an x402 counterparty
  Given a 0x address, returns whether it is a real x402 service, a relayer, a treasury, or has no track record, and whether it is safe to pay. The check to run before your agent pays anyone over x402.

• Score a wallet (solvency and liveness)
  Returns a Witnos score for any address: solvency (can it pay) and liveness (is it active), the safe-to-pay and creditworthiness read before extending value to a counterparty.

• Assess token risk (code and people)
  Scans a token contract and the wallets around it for risk: honeypot and controller signals in the code plus concentration and behavior in the holders. Run before touching a token.

• Score agent credit
  Creditworthiness for an autonomous agent wallet: balance, runway (days until broke) and observed burn, so you know if an agent can honor what it promises.

• Preflight a payment
  A pre-action gate: before your agent sends an x402 payment, get a block/warn/allow verdict with reason codes and a changed-since cursor, so a bad counterparty is caught the instant before you pay.

• Read the de-noised settlement census
  The state of x402: of all USDC moving through x402, which wallets are real end services versus relayers and treasuries. A de-noised settlement graph no directory publishes.

• Mint or check a Witnos passport
  Give your agent a home: a persistent identity, tamper-evident hash-chained memory you write and recall across sessions, and a reputation other agents can verify before they trust or pay you.
