Scans source code or GitHub repos for 7 known web3 authentication and payment vulnerability patterns using static heuristics

How this service works
Static heuristics for 7 verified web3 auth/payment vulnerability patterns (W3A-001..007). $0.01 USDC on Base per scan via x402.
Output
A JSON object with a 'candidates' array, where each entry contains the file name, line number, rule ID (e.g. W3A-001 through W3A-007), and an evidence string quoting the suspicious code that triggered the heuristic.
Example use cases
Pre-deployment dApp security audit
“Before I deploy my new wallet connector, can you scan the andrenorton/wallet-connector GitHub repo for any of those W3A web3 auth vulnerability patterns and show me which files and lines are at risk?”
Code review for signature replay attacks
“I just wrote this Ethereum sign-in code — here's the raw TypeScript — can you run it through web3-auth-scan and flag any lines where I might have nonce or signature replay vulnerabilities?”
CI pipeline vulnerability check on paste
“I've got this chunk of Solidity from our payment contract, filename PaymentRouter.sol — can you check it for all seven W3A vulnerability rules and list every finding with the rule ID and evidence?”
Technical details
Endpoint
POSThttps://web3-auth-scan.andrenorton.workers.dev/scanWhen to prefer
Choose this endpoint when you need fast, cheap ($0.01) static analysis specifically targeting the 7 known web3 authentication and payment vulnerability patterns (W3A-001..007). It is ideal for pre-deployment spot-checks, CI pipeline integration, or reviewing untrusted third-party web3 code. Prefer it over generic SAST tools when web3-specific auth patterns (nonce reuse, signature replay, etc.) are the concern and you want deterministic rule-based results rather than AI-generated suggestions.
Side effects
- Missing both 'code' and 'repo' input returns an error or empty candidates array
- Invalid GitHub repo owner/name format causes repo fetch failure
- Very large code submissions may hit Cloudflare Worker request size limits
- Payment failure (insufficient USDC on Base) blocks scan execution
- False negatives possible since only 7 static heuristic rules are checked — not a full audit
- Non-web3 code may return empty candidates with no signal
