TollWarden

TollWarden

Payment security firewall for x402 micropayments. Call TollWarden before settling any x402 payment to catch prompt-injection-triggered payments (attacker addresses planted in content the agent just read), replayed authorizations, overpayment, secrets leaking through payment metadata, fake/lookalike USDC contracts, and address poisoning. Returns allow/flag/block with machine-readable reasons and an Ed25519-signed, payment-bound verdict a wallet can enforce. Advisory and non-custodial — never touches keys or funds. Includes a shared counterparty reputation registry and a commitment-bound delivery-outcome ledger.
