Eth-Mnemonic-to-Keystore (emtk)

A simple CLI utility for generated an encrypted keystore from a mnemonic.

This tool has not been audited by Sigma Prime. Use at your own risk.

Features

• Based on alloy.
• Minimal dependencies.
• Builds a stand-alone binary, ideal for air-gapped generation.
• Easy cross-compilation.

Limitations

• Only supports English mnemonics. Submit a PR for more languages.

Usage

1. Install the binary to your ~/.cargo/bin (or equivalent)

make install

2. Generate a keystore

emtk --index 0 \
    --password meow \
    --output-dir ./ \
    --mnemonic "wear crucial left gorilla zebra child similar salmon seed survey artwork invite digital giggle enjoy"

The --index'th address will be derived from the --mnemonic. The resulting keystore will be saved to --output-dir with a UUID filename (without a .json extension). The keystore will be encrypted with --password.

The UUID filename will be output to stdout.

Cross-Compilation

Cross-compilation is provided via cross and therefore uses Docker.

# x86_64 (Intel)
make build-x86-64
# aarch64 (ARM)
make build-aarch64

Binaries will be compiled to ./emtk/target/<PLATFORM>/release/emtk.
