walleth

A (WIP) Rust library for easily create, manage, use and protect Ethereum accounts. Interacting with keys and signing transactions securely (will be) made as easy as breathing.

Warning

This library is under development and APIs are rapidly changing iIncluding this README!). Make sure to lock to a specific crate version to avoid updates.

Features

  • 💳 Multiple BIP39 HD wallets management
  • 🔐 Built-in encryption for all keys managed
  • ✨ Built-in bytes serialization / deserialization for the entire keychain
  • 🚧 Customizable wallet classes (HD, single, etc..)
  • 🌎 Built-in network scraper
  • 🛒 Built-in transaction manager
  • ⚡️ Built-in JSON-RPC Provider engine

Usage

Create a new keychain

use walleth::keychain::Keychain;
use walleth::hdkey::HDKey;

let mut keychain = Keychain::<HDKey>::new();

Add a new HD Wallet to the keychain

use walleth::keychain::Keychain;
use walleth::hdkey::{HDKey, hdkey_factory};

let mut keychain = Keychain::<HDKey>::new();
let hdwallet = keychain.add_multi_keypair(hdkey_factory, None).unwrap();

Add a new HD Wallet to the keychain with a specific mnemonic

use walleth::keychain::Keychain;
use walleth::hdkey::{HDKey, hdkey_factory};

let mnemonic = "grocery belt target explain clay essay focus spatial skull brain measure matrix toward visual protect owner stone scale slim ghost panda exact combine game".to_string();
let mut keychain = Keychain::<HDKey>::new();
let hdwallet = keychain.add_multi_keypair(hdkey_factory, Some(mnemonic)).unwrap();

Derive keys and sign

use walleth::{
  keychain::Keychain,
  hdkey::{HDKey, hdkey_factory},
  identity::{
    MultiKeyPair,
    AccountDeriver,
    signer::{Signer, Signable}
  },
};

let mut keychain = Keychain::<HDKey>::new();
let hdwallet = keychain.add_multi_keypair(hdkey_factory, None).unwrap();

// Derive an account at path
let account = hdwallet.account_at(0).unwrap();

// Sign a message
let signature = hdwallet.sign(&account, "Hello".as_bytes()).unwrap();

// Verify signature
hdwallet.verify(&account, "Hello".as_bytes(), &signature);

Note
