Smart Contract Audit in Seconds, Not Weeks

Six integrated tools covering every phase of a smart contract's lifecycle — plan securely, develop safely, deploy with confidence. Free to try, five chains supported, instant reports.

The six tools

• Secure Development Checklist — 40 architecture, documentation and design decisions to get right before writing Solidity.
• Rekt Test — 12 critical questions based on Trail of Bits' secure development guidelines, scored into a security maturity benchmark.
• Solidity Code Scanner — paste Solidity source for instant AI vulnerability analysis of a single .sol file.
• Transaction Simulator — preview what a contract function will do before signing it: asset movements, gas costs and risk rating.
• Contract Audit by Address — a full AI audit of any deployed contract, with vulnerability report, trust score and deploy-readiness verdict.
• Threat Intelligence — real-world exploits tracked across major chains, matched against the patterns found in your own contract.

15 vulnerability patterns checked automatically

Before every AI audit, a deterministic pre-scanner runs all 15 patterns against the contract source. Findings are injected into the AI prompt so the model validates, refutes or expands on each one.

• Missing reentrancy guard and unchecked low-level calls
• tx.origin authentication and single-step ownership transfer
• delegatecall usage, selfdestruct and inline assembly
• Block timestamp dependence and ecrecover malleability
• Unbounded loops, unchecked arithmetic, floating pragma and abi.encodePacked collisions

Supported chains

Ethereum, Polygon, Arbitrum, Base and BNB Chain. Per-chain security guides: Ethereum, Polygon, Arbitrum, Base and BNB Chain.

Buying a token?

Paste a contract address into the token checker and see what the people holding the keys can do to the people holding the token: create new supply, block transfers, raise the sell tax or replace the contract logic. Read live from the chain, with the controlling addresses named. Free, no signup.
