1. Overview

Wagyu is a feature-rich command-line utility to generate a cryptocurrency wallet.

Wagyu enables developers to build their own cryptocurrency application using the following modules.

Library	Standard Wallet	HD Wallet	Mnemonic	Network
wagyu-bitcoin	P2PKH P2SH-P2WPKH Bech32	BIP-32 BIP-44 BIP-49 Custom	BIP-39	Mainnet Testnet
wagyu-ethereum	Standard	Ethereum Ledger Trezor Keepkey Custom	BIP-39	All
wagyu-monero	Standard Integrated Subaddress	N/A	Electrum	Mainnet Testnet Stagenet
wagyu-zcash	P2PKH Sprout Sapling	ZIP-32	N/A	Mainnet Testnet

Wagyu can support new cryptocurrencies by implementing the model as outlined in this module.

Library	Standard Wallet	HD Wallet	Mnemonic	Network
wagyu_model	Address Public Key Private Key	Derivation Path Extended Public Key Extended Private Key	Mnemonic Wordlist	Network

2. Build Guide

2.1 Install Rust

We recommend installing Rust using rustup. You can install rustup as follows:

• macOS or Linux:

  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
  

• Windows (64-bit):

  Download the Windows 64-bit executable and follow the on-screen instructions.

• Windows (32-bit):

  Download the Windows 32-bit executable and follow the on-screen instructions.

2.2a Build from Homebrew (for macOS)

For macOS users, we recommend installing wagyu via Homebrew as follows:

brew install wagyu

2.2b Build from Crates.io

We recommend installing wagyu this way. In your terminal, run:

cargo install wagyu

Now to use wagyu, in your terminal, run:

wagyu

2.2c Build from Source Code

Alternatively, you can install wagyu by building from the source code as follows:

# Download the source code
git clone https://github.com/AleoHQ/wagyu
cd wagyu

# Build in release mode
$ cargo build --release

This will generate an executable under the ./target/release directory. To use wagyu, run the following command:

./target/release/wagyu
