Modules

This page outlines the general documentation for all modules in the heimdall-rs toolkit.

Shared Options

These options are shared by nearly all modules on heimdall-rs, and have the same functionality across all modules.

Option	Description
-v, --verbose	More verbose output per occurrence
-r <RPC_URL>, --rpc-url <RPC_URL>	The RPC provider to use when connecting to an RPC node
-o <OUTPUT>, --output <OUTPUT>
-h, --help	Show the help message

Verbosity

The -v option can be used to increase the verbosity of heimdall-rs. This can be useful for debugging issues with heimdall-rs. The -v option can be used multiple times to increase the verbosity of heimdall-rs.

Option	Level
-v	Warn
-vv	Info
-vvv	Debug
-vvvv	Trace
-vvvvv	Full

RPC URL

The -r option can be used to specify the RPC URL to use when connecting to an RPC node. This RPC URL can theoretically be used on any EVM compatible chain, as long as the data it is fetching is from the same chain.

This option is used for interacting with the RPC node within the module.

Output

The -o option can be used to specify the output file or directory to use when writing output from heimdall-rs.

$ heimdall disassemble <TARGET> [OPTIONS]

Options

Option	Description
TARGET	The target to disassemble, either a file, bytecode, contract address, or ENS name

Decode

This module allows you to decode raw calldata into readable types, without the need for an ABI.
