Repository-specific x402 payment attack pack. PayGuard reviews one public or sanitized payer flow and returns five adversarial payment fixtures, expected ALLOW/BLOCK/REQUIRE_APPROVAL decisions, the exact pre-sign integration point, runnable test instructions, and risk notes. No wallet keys or private credentials.

The agreement

Buyer supplies one public repository URL or sanitized payer-flow code plus rail/network, currency, signer boundary, and one expected normal payment example. Delivery must include five custom adversarial JSON fixtures covering duplicate/replay, price anomaly, new endpoint or payee, budget breach, and prompt-injection-to-payment; expected PayGuard decisions and reason codes; the exact pre-sign insertion point; runnable test instructions; and a concise risk note. No custody, signing, secrets, or claims of complete security.
