What is ai-contractauditor?

SMART_AUDIT, also called AI-ContractAuditor, is a web app that checks Solidity smart contract code for common security problems and suggests fixes. You paste your contract code into the editor, run an audit, and within about two seconds it reports which vulnerabilities it found, gives the contract a security score from zero to one hundred with a letter grade, and can generate a corrected version of the code with comments explaining the changes. It looks for six specific kinds of problems: reentrancy attacks, unsafe use of tx.origin for authorization, missing access control, integer overflow, unsafe external calls, and unchecked low level calls. After an audit, you can compare the original and fixed code side by side, download the full report as a PDF, or generate a shareable link that encodes the report so others can view it without needing your account. The app also has a documented API, reachable at a single POST endpoint, that returns the same audit results as structured JSON. This is meant to let other tools or AI agents send contract code and get findings back programmatically, without needing an API key or external service. Past audits are saved to the browser's local storage so you can look back at your history and see stats over time. The project was built as an assignment submission for a forward deployed engineer role and is built with Next.js and TypeScript. It works out of the box: after cloning the repository and running the install and start commands, you can open it locally without setting up any API keys. It is aimed at Solidity developers and smart contract teams who want a quick first pass security check before deeper manual review.
