A reputation passport for x402 payer wallets. We read an address's public USDC history on Base and distil it into a 0–100 Trust Score: age, volume, frequency, counterparty diversity and recency.

How to use

  1. Paste an agent (payer) wallet address.
  2. Click <strong>Get passport</strong> to read its public USDC history.
  3. Review the 0–100 Trust Score and its five factors: age, volume, frequency, diversity and recency.
  4. Use the tier (new → platinum) to decide whether to transact.
