Online Solidity Decompiler
There are many contracts deployed on the Ethereum network with no source or ABI publicly available.
This makes verifying their security and understanding their behaviour a difficult task without the right tools, such as a decompiler.
This tool decompiles Ethereum contract bytecode into more readable Solidity-like code, allowing for better understanding of such contracts.
