seedgen

A small CLI for generating BIP39 mnemonics and BIP32 seeds.
Useful for setting up hot wallets or providing a BIP32_SEED to other services.

Installation

Build from source

Requires Rust 1.88+.

git clone https://github.com/SovaNetwork/seedgen
cd seedgen
cargo build --release
./target/release/seedgen

Run with Docker

Images are published to GitHub Container Registry:

docker run --rm ghcr.io/sovanetwork/seedgen:latest

To output only the raw hex seed (e.g. for BIP32_SEED):

docker run --rm ghcr.io/sovanetwork/seedgen:latest --seed-only

Usage

Generate mnemonic + seed + xprv/xpub:

./seedgen

Generate seed only:

./seedgen --seed-only

Security

This tool uses the zeroize crate to wipe sensitive data (entropy, seeds, private keys) from memory after each run. Without zeroization, those secrets could remain in memory until overwritten, potentially exposing them via crash dumps or memory leaks.
