Limitations
audit.new has limits to keep the platform fast and fair. Most limits depend on your audit tier.
File size limits#
- Pasted code: maximum 2MB of source code
- ZIP upload: maximum 10MB per archive
Runtime caps by tier#
| Tier | Credits | Max Runtime | Vulnerability Categories |
|---|---|---|---|
| Quick | 1 | 20 minutes | Reentrancy, overflow/underflow, access control |
| Standard | 3 | 45 minutes | Quick + oracle, flash loans, signature replay, logic bugs |
| Deep | 8 | 90 minutes | Standard + proxy risks, token integration, cross-contract, economic attacks |
If an audit reaches its runtime cap, results are returned for the analysis completed so far.
Supported networks#
Etherscan URL submission supports these EVM-compatible networks:
- Ethereum (Etherscan)
- Binance Smart Chain (BscScan)
- Polygon (PolygonScan)
- Arbitrum (Arbiscan)
- Optimism (Optimistic Etherscan)
- Base (BaseScan)
- Avalanche (SnowTrace)
- Fantom (FTMScan)
Other chains
For contracts on unsupported chains, use the paste code or ZIP upload method to submit your source code directly.
Accuracy considerations#
- AI analysis — May produce false positives or miss some vulnerability types
- Not a replacement — For production protocols, complement with a manual audit
- Solidity focus — Currently optimized for Solidity smart contracts
Not a guarantee
A clean audit result does not guarantee a contract is free of vulnerabilities. AI-powered analysis is a valuable tool in a broader security strategy.
