Bitcoin Wallet Library in Rust

This is a library to build Bitcoin wallets with Rust. It uses BIP32 key derivation, BIP39 mnemonics and BIP44 key hierarchy which makes it compatible to TREZOR, Ledger and many other wallets.

Goal

Offer a standalone wallet in conjunction with rust-bitcoin-spv. I plan to add TREZOR and Ledger support.

Status

This is work in progess, far from production quality. It aims to serve parallel development of an SPV client and a Lightning Node.

Basic Usage

Install docker, docker-compose and rustup.

Optionally install electrumx. Run in some tmp directory:

git clone https://github.com/romanz/electrs
cd electrs
git checkout a61e1b3b7a150c52188fc7c412233068c156c56b
cargo install --debug --path .

Launch electrumx:

electrs --network=regtest --jsonrpc-import --cookie=user:password --daemon-rpc-addr=127.0.0.1:18332

Install the wallet:

git clone https://github.com/LightningPeach/rust-wallet.git
cd rust-wallet/rust-wallet-grpc
cargo install --debug --path .

If the wallet already installed the last command should be:

cargo install --debug --force --path .

in order to rewrite the binary.

Launch the wallet:

docker-compose up
wallet

It is possible to run wallet with electrumx:

wallet --electrumx

See wallet --help for more information.

Generate some money to bitcoind and send to the wallet

docker exec -ti rust-wallet_bitcoind_1 sh
bitcoin-cli -regtest -rpcuser=user -rpcpassword=password generate 110
wallet-cli newaddress

bitcoin-cli -regtest -rpcuser=user -rpcpassword=password generate 1
wallet-cli sync_with_tip
wallet-cli walletbalance

Send money back to the bitcoind

Contributions and Vision

The goal is a library for key derivation, storage, serialization and account management.
