StatusUnknown
Output
An audit report detailing detected security vulnerabilities, potential exploits, code quality issues, and recommendations for the submitted smart contract. May include severity ratings and suggested fixes for identified problems.
Example use cases
DeFi protocol security review
“I just wrote a lending protocol in Solidity — can you audit the contract code for reentrancy attacks, flash loan exploits, and any access control issues before I deploy it to mainnet?”
NFT contract vulnerability scan
“Can you check my ERC-721 NFT smart contract for security vulnerabilities? I want to make sure there are no minting exploits or ownership bugs.”
Pre-deployment safety check
“I'm about to deploy this ERC-20 token contract — can you run a full audit on it and flag any issues with integer overflow, unauthorized minting, or other common Solidity security problems?”
Technical details
Endpoint
GEThttps://gpt.558686.xyz/v1/audit/contract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need automated GPT-powered smart contract security auditing without setting up a local analysis environment. Best suited for Solidity/EVM contracts where you want a quick AI-driven vulnerability scan before deployment or code review. Prefer over manual review tools when speed and accessibility are priorities.
Side effects
- Empty or invalid contract code returns no useful analysis
- Rate limiting or payment failure returns 402 error
- Malformed input schema returns 400 error
- Very large contracts may be truncated or return incomplete results
- Non-Solidity or non-EVM contract code may produce inaccurate results
