How this service works
Smart Contract Audit — Security review of a single contract
Output
Returns a job ID and status URL immediately after submission; once complete, delivers a detailed security report accessible via a report URL (and optionally POSTed to a callback URL), covering identified vulnerabilities, severity levels, and recommendations for the audited contract.
Example use cases
Pre-deployment DeFi contract audit
“Before I deploy my new liquidity pool contract, can you audit the Solidity source code I pasted below and flag any critical vulnerabilities or common DeFi attack vectors?”
Third-party token contract review
“I'm about to invest in this project — can you audit the token contract at 0xabc123... on Etherscan and tell me if there are any backdoors, rug pull mechanisms, or security issues?”
NFT minting contract security check
“I just wrote an NFT minting contract and I want to make sure it's safe — here's the source code. Can you do a security audit and highlight anything that could be exploited?”
Technical details
Endpoint
POSThttps://www.onedollaraudit.com/api/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, affordable ($1) automated security audit of a single Ethereum or Base smart contract, either by verified on-chain address or by pasting source code directly. Ideal for pre-deployment checks, third-party contract reviews, or any time you want a fast vulnerability scan without engaging a full manual audit firm. Best suited for EVM-compatible contracts verifiable on Etherscan or Basescan.
Side effects
- Contract address not verified on Basescan/Etherscan — audit cannot proceed without verified source
- Source code too short (under 10 characters) — rejected as invalid input
- Invalid callback URL format — must be a valid HTTPS URL
- Payment failure — $1 USDC x402 payment not completed
- Unsupported contract language or chain — may not cover non-EVM contracts
- Timeout on complex contracts — large contracts may take longer to process
