Inspiration

Smart contracts are widely used in blockchain operations, but a small coding mistake can lead to serious security vulnerabilities and financial losses. we wanted to build a simple tool that helps developers identify common solidity security issues before deploying their contracts.

What it does

Smart contact vulnerability Scanner analyzes solidity smart contract code and automatically identifies common security vulnerabilities before the contract is deployed.

How we built it

The project uses "Python Flask backend" for processing requests and running the security analysis. The frontend provides an easy interface where users can submit Solidity code and view the scan results.

Challenges we ran into

One of the main challenges was detecting vulnerabilities without generating too many false positives. Solidity contracts implement the same functionality in different ways, so designing reliable detection rules required careful testing.

Accomplishments that we're proud of

Built a functional smart contract scanner that detects common solidity vulnerabilities and provides clear severity levels, explanations, and recommended fixes.

What we learned

Through this project, we learned how smart contracts work, how common Solidity vulnerabilities occur, and how static analysis can be used to detect potentially dangerous code patterns.
