15 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Complete AI-powered smart contract security audit - analyzes code against checklist and provides detailed findings with severity levels. Returns immediately (202 Accepted) with a polling URL. Poll GET {jobStatusUrl} ever...
AI-powered smart contract audit checklist matching - analyzes contract code and returns relevant security checklist items. Returns immediately (202 Accepted) with a polling URL. Poll GET {jobStatusUrl} every 5-10 seconds...
Quick Solidity pre-audit check, $0.90 USDC on Base: send source or a verified contract address + chain; the same automated engine returns the verdict (grade, score, security and owner-trust risk), severity counts, the to...
IBAN validator: validate an IBAN's length for its country, permitted character classes per field, and the ISO 7064 mod-97-10 check digits. Returns the verdict with a specific failure reason, the electronic and print form...
Solidity function selector and event topic: compute the Keccak-256 hash of a function or event signature and derive the 4-byte selector and the 32-byte topic. Normalises the signature first — strips parameter names, expa...
Compile Solidity contracts with the Remix compiler, supporting multiple files, custom versions, and optimization settings
Deterministic static pattern scan of Solidity smart-contract source text - a fixed ruleset flagging tx.origin authentication, delegatecall, selfdestruct, unchecked low-level calls, unchecked .send(), floating pragmas, bl...
Fetch the verified Solidity source files and compiler metadata for a contract address from an open verified-contract repository. Covers 8 EVM mainnets (ethereum, base, polygon, arbitrum, optimism, bsc, gnosis, celo). Con...
pactlint (Tanod) source lookup: verified Solidity source, ABI and compiler settings of a contract (Sourcify) Use when an agent needs the verified source, ABI and compiler settings of a contract at a known address.
Use when an agent is building something Ethereum will hash and must get the same digest the chain gets: Keccak-256 of any string or hex payload, with the byte count. It is NOT SHA3-256, and that confusion is the usual re...
Payment flow verification for agents integrating x402: confirms your wallet and payment channel work before you spend on a real endpoint. Category: infra.
ABI and readable function/event signatures of a verified smart contract from Sourcify, with contract name, compiler, licence, proxy implementation and deployer. Use before calling or decoding a contract.
Autonomous smart contract security auditor — 20+ vulnerability classes, PoC exploits
EVM Watchdog: npm/Foundry dependency advisories split by on-chain vs toolchain surface, plus known Solidity bug-class leads, for a public GitHub repo. A scan, not an audit.
Use this before adding or upgrading an npm dependency (OpenZeppelin, solmate, hardhat…), or to triage a lockfile: GitHub/OSV advisories affecting a whole package-lock.json or yarn.lock (or up to 100 listed packages) at t...
