By scanning, you agree to our Terms of Service. Results are an automated scan, not a security audit.
Free scans run on our own engine and your code isn't saved. Signed-in scans go only to your private history. We never use your code to train AI models. How we handle code
Analyzing smart contracts across
Three Steps to Secure Contracts
Get professional-grade smart contract analysis in minutes, not weeks
Upload Your Contract
Paste your Solidity, Vyper, or Rust smart contract code or upload a file. No setup or registration required.
AI Scans for Threats
Our AI analyzes 13 high-impact vulnerability classes including reentrancy, access control flaws, and integer overflow in seconds.

Powerful Audit Features
Everything you need for comprehensive smart contract security analysis
Instant Contract Breakdowns
Plain English explanations of what your contract does, its functions, and attack surface.
Pre-Deployment Security
Catch vulnerabilities before they go on-chain — when fixing costs dollars, not millions.
Shareable Security Reports
Clear PDF reports to share with your team, investors or DAO, labelled as automated scans, not audits.
Built for Web3 Founders
Web3 developers use SmartContractAuditor.ai to catch vulnerabilities before hackers do
Tested on Known Bugs, Not Promises
We plant real exploit patterns (The DAO, Parity, BeautyChain, Poly Network) in test contracts and check the scanner catches them without flagging safe code.
Small single-bug contracts measure whether each detector works. A scan is a first pass before a manual audit, not a replacement for one.

Simple, Transparent Pricing
Professional smart contract security for every budget
Frequently Asked Questions
Everything you need to know about smart contract audits
What is a smart contract audit?
A smart contract audit is a comprehensive security review that examines blockchain smart contract code for vulnerabilities, bugs, and security flaws. Our AI-powered audit delivers instant analysis in seconds, detecting reentrancy attacks, access control flaws, and the other high-impact bug classes we check (13 in total). It is an automated first pass, not a substitute for a manual audit: for contracts that will hold real funds, we recommend a manual audit before mainnet.
How long does a smart contract audit take?
With SmartContractAuditor.ai's AI-powered analysis, you get instant results in seconds rather than weeks. Traditional manual audits can take 2-8 weeks.
What types of vulnerabilities can you detect?
Our AI detects 13 high-impact vulnerability classes including reentrancy attacks, access control flaws, integer overflow, oracle manipulation, signature replay, unprotected initializers and denial-of-service loops.
How much does a smart contract audit cost?
We offer a 14-day free trial with 3 daily tokens. Our Pro plan starts at $100/month for 150 tokens. Traditional manual audits cost $5,000–$50,000+ and take weeks to complete.
What blockchains and languages do you support?
We support Ethereum (Solidity), Vyper, and Solana (Rust) smart contracts. Our AI is trained on thousands of contracts across these languages.
