Comprehensive smart contract security
From vulnerability detection to detailed remediation reports — everything you need to ship secure smart contracts.
Deep Vulnerability Detection
AI-powered detection of reentrancy, flash loan attacks, oracle manipulation, signature replay, and 20+ vulnerability categories in Solidity contracts.
Multi-Chain Support
Audit contracts on Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, Avalanche, and Fantom. Fetch verified source code directly from block explorers.
Real-Time Analysis
Watch your audit progress in real-time with live status updates. Get comprehensive results in minutes, not weeks.
Comprehensive Reports
Detailed findings with severity ratings (Critical/High/Medium/Low), exact code locations, CWE references, and actionable fix recommendations. Export to PDF.
Multiple Input Methods
Submit via Etherscan URL, GitHub repo, pasted Solidity code, or ZIP upload. Flexible workflows for any development setup.
AI-Powered Analysis
Multi-phase audit methodology: map contract structure, hunt for attack surfaces, simulate exploits, and verify findings using expert security heuristics.
How it works
Three steps to secure smart contracts
Submit your contract
Paste an Etherscan URL, GitHub repo link, raw Solidity code, or upload a ZIP archive. Supports 8 EVM-compatible networks.
AI analyzes for vulnerabilities

Why smart contract auditing matters
Smart contract exploits have cost the industry billions. Automated security analysis helps you catch vulnerabilities before attackers do.
Ship secure code
Catch reentrancy, access control flaws, and logic bugs before they reach mainnet. Deploy with confidence knowing your contracts have been thoroughly analyzed.
Save time and money
Get results in minutes instead of weeks. Automated AI analysis at a fraction of traditional audit costs — without sacrificing depth or accuracy.
Continuous protection
Audit every contract update. Subscription plans give your team ongoing security coverage so you can iterate fast without compromising safety.
Built for every Web3 use case
Whether you're building DeFi, NFTs, DAOs, or tokens — audit your contracts before deployment.
DeFi Protocols
Audit lending pools, AMMs, yield vaults, and liquidity protocols. Detect oracle manipulation, flash loan vectors, and economic exploits before mainnet deployment.
Start audit→NFT Projects
Secure minting contracts, marketplaces, and royalty systems. Catch access control flaws and reentrancy in mint and transfer functions.
Start audit→DAOs & Governance
Audit governance contracts, treasury management, and voting mechanisms. Identify privilege escalation and proposal manipulation risks.
Start audit→Token Launches
Pre-launch security review for ERC-20, ERC-721, and ERC-1155 tokens. Find overflow bugs, approval issues, and supply manipulation vectors.
Start audit→Trusted by Web3 teams shipping secure code
Join hundreds of teams using audit.new to find vulnerabilities before attackers do
We caught a critical reentrancy bug 2 days before our mainnet launch. audit.new saved us from what could have been a multi-million dollar exploit.
Alex Kim
CTO, DeFi Protocol
Traditional audits took 4 weeks and cost $50K. audit.new found the same class of issues in 30 minutes for a fraction of the cost. Game changer for our dev cycle.
Maria Santos
Lead Developer, NFT Marketplace
We run an audit on every PR that touches our contracts. The subscription plan makes continuous security affordable for our team.
