Solidity Bugs in Yul

This repo is a reference of many Solidity vulnerabilities compiled to Yul, an intermediate language for the EVM. It is meant to be a reference for auditors that are dealing with Yul codebases as opposed to Solidity codebases.

The examples are taken from the following references:

• Not So Smart Contracts
• Solidity Security: List of known vulnerabilities and anti-patterns

Note that due to the experimentation nature of Yul, many smart contracts written in Solidity to not compile yet.

TODO:

• Add explainer of vulnerability and how it translates to Yul
• Add compilable examples for certain vulnerabilities in folders that only contain a .sol file
