heimdall-rs

Overview

Heimdall is an advanced EVM smart contract toolkit specializing in bytecode analysis and extracting information from unverified contracts. Heimdall is written in Rust and is designed to be fast, modular, and more accurate than other existing tools.

Currently, Heimdall supports the following operations:

• EVM Bytecode Disassembly
• EVM Smart-Contract Control Flow Graph Generation
• EVM Smart-Contract Decompilation
• Smart-Contract Storage Dumping
• Raw Transaction Calldata Decoding
• Raw Transaction Trace Decoding

Installation & Usage

Ensure that Rust & Cargo are installed:

curl https://sh.rustup.rs -sSf | sh

Heimdall's update and installation manager, bifrost, can be installed using the following command:

curl -L http://get.heimdall.rs | bash

If you want to manually install bifrost, you can download the latest release from here.

Once you have installed bifrost, you can use it to install Heimdall using the following command from a new terminal:

bifrost

After compilation, the heimdall command will be available to use from a new terminal. For advanced options, see the bifrost documentation.
