Open Source

Advanced EVM bytecode toolkit for decompilation, disassembly, and analysis. Reconstructs Solidity-like source from deployed bytecode.

About

Heimdall is an advanced EVM smart contract toolkit written in Rust that provides decompilation, disassembly, and CFG generation from deployed bytecode. It can reconstruct Solidity-like source code from on-chain contracts, making it invaluable for analyzing unverified contracts, investigating exploits, and reverse-engineering protocol logic. Heimdall supports all EVM-compatible chains and integrates with Etherscan-like APIs.
