Quickstart
This guide walks through a minimal single-signature flow on Liquid testnet: create a signer, open a wollet, sync, send, sign, and broadcast.

For installation options see Installing LWK. For deeper explanations see How LWK Works.
1. Install
Pick your language binding (see Installing LWK for all platforms):
pip install lwk# Cargo.toml
[dependencies]
lwk_wollet = "0.17.0"
lwk_signer = "0.17.0"
lwk_common = "0.17.0"npm install lwk_wasm2. Create a signer
use lwk_signer::{bip39::Mnemonic, SwSigner};
let mnemonic = Mnemonic::generate(12)?;
let is_mainnet = false;
let signer = SwSigner::new(&mnemonic.to_string(), is_mainnet)?;from lwk import Mnemonic, Signer, Network
mnemonic = Mnemonic.from_random(12)
signer = Signer(mnemonic, Network.testnet())const mnemonic = lwk.Mnemonic.fromRandom(12);
const network = lwk.Network.testnet();
const signer = new lwk.Signer(mnemonic, network);3. Open a wollet
Derive a CT descriptor from the signer and create a watch-only wollet:
use lwk_wollet::{Network, WolletBuilder, WolletDescriptor};
let desc = signer.wpkh_slip77_descriptor()?;
let wd = WolletDescriptor::from_str(&desc)?;
let mut wollet = WolletBuilder::new(Network::TestnetLiquid, wd).build()?;desc = signer.wpkh_slip77_descriptor()
wollet = Wollet(network, desc, datadir=None)const desc = signer.wpkhSlip77Descriptor();
const wollet = new lwk.Wollet(network, desc);4. Sync and check balance
Connect a blockchain client and scan the chain. Fund the wallet with testnet L-BTC from liquidtestnet.com/faucet if needed.
See Blockchain Scan for client setup.
5. Send, sign, broadcast
- Create an unsigned PSET with Transaction Creation.
- Sign it with Transaction Signing.
- Broadcast via Transaction Broadcast.
