Kobe is a lightweight cryptocurrency wallet toolkit written in Rust. It provides both a CLI tool and reusable libraries for Bitcoin and Ethereum wallet generation with full no_std support for embedded environments.

Features

Multi-Chain Support — Bitcoin (Legacy, SegWit, Native SegWit) and Ethereum
BIP39/BIP32/BIP44 — Standard mnemonic and HD wallet derivation
no_std Compatible — Use in embedded systems and WebAssembly
Secure by Default — Memory zeroization, no unsafe code
Minimal Dependencies — Small binary size, fast compilation

Installation

CLI Tool

cargo install kobe

Quick Start

CLI Usage

Generate a Bitcoin wallet:

kobe btc new

      Network      mainnet
      Address Type P2WPKH (Native SegWit)
      Mnemonic     sunny elephant wink holiday renew retire oak lady trial car develop giggle

      Path         m/84'/0'/0'/0/0
      Address      bc1qkwxmjfssd8vft2q8hpsvkqlehs8sawqjec3zlg
      Private Key  KwLNMJLXHawRxuPT7iEvcqoXc8rAc4QsXLpuMx98ekkpXwnZ2tNY

Generate an Ethereum wallet:

kobe eth new

      Mnemonic     clean uniform crush friend dog episode message essay monitor phone left miracle

      Path         m/44'/60'/0'/0/0
      Address      0xD09FF64A19C37cc39d86EcCB9915ef0df0628146
      Private Key  0xb70cd395aba0e5a6ee3aee6956413b23b45e4505da590ec00839db7ade993d49

More options:

kobe btc new --words 24 --count 5 --testnet
kobe eth new --passphrase "secret" --count 3
kobe btc import --mnemonic "your twelve word mnemonic phrase here"
kobe eth import-key --key 0x...

Library Usage

use kobe_core::Wallet;
use kobe_eth::Deriver;

// Generate a new wallet
let wallet = Wallet::generate(12, None)?;
println!("Mnemonic: {}", wallet.mnemonic());

// Derive Ethereum addresses
let deriver = Deriver::new(&wallet);
let account = deriver.derive(0, false, 0)?;

println!("Address: {}", account.address);
println!("Private Key: 0x{}", account.private_key_hex);
