Solidity Smart Contract Attack Vectors:

This Repository contains list of Solidity Attack Vectors. It includes most solidity vulnerabilities collected from various sources like SWC Registry, DeFi threat, DASP Top-10 and contents all over Internet. You can click each attack vectors and find details about it. This repository will be actively maintained and updated by QuillAudits.

If you find any attack vectors missing, you can create a pull request and be a contributor of the project.
