🛡️ Smart Contract Audit

Pre-payment verification, not post-payment trust scores. We audit the contract, the token, and the endpoint's payment logic before your agent spends USDC.

From $2 · Base Instant Smart Contract Audit Two tiers — a $2 static pre-check (reentrancy, access control, integer overflow) or a $20 AI deep audit across Solidity / Rust / Move. Severity-ranked findings in minutes, paid in USDC. First audit free per signed wallet while the shared daily pool lasts. Run an audit → 9 Vulnerability Classes What Our AI Detects — the Vulnerability Library Reentrancy, signature replay, storage collision, access control, unsafe calls, tx.origin, overflow, delegatecall, selfdestruct — each with a worked case study. Browse the library → Real Projects · Anonymized Real-Project Audit Results by Category AI-agent protocols, lending, escrow — vulnerability classes found and report pricing ($200–$1,000). Names withheld under responsible disclosure. See the results → First free · $5 x402 Payment Trust Check Is that endpoint really verifying payment? Black-box probe sends forged txHash / signature / replay and reports SAFE · RISK · NOT_X402 — before your agent pays. First check free per wallet. Check an endpoint → We verify ourselves first Self-Verified Endpoints We run our own forged-payment probe against minia2a endpoints — these pass SAFE before anything is delivered. Proof, not claims.
