Integrate Liquid Network

This guide walks you through adding Liquid Network support to your exchange, broker, or fintech platform. By the end, you'll know how to create wallets, generate deposit addresses, track balances, send and receive LBTC and Liquid assets, query blockchain data, and optionally support AMP2 managed assets like regulated securities and stablecoins.

No prior Liquid experience required. We'll start from zero.

Who this is for

Exchanges adding Liquid deposits and withdrawals
Brokers settling trades on Liquid
Fintech platforms integrating LBTC or Liquid issued assets (USDt, securities, etc.)
Custodians managing Liquid wallets on behalf of clients

Core path (most integrations): Your backend uses LWK to manage wallets and talks to Esplora or Waterfalls for blockchain data. That's it.

AMP2 path (optional): If you want to support issuer controlled assets (regulated tokens, securities), you additionally register as a venue with AMP2 and handle cosigned transactions through their proxy.

What you'll need

Component	Purpose	Required?
LWK (Liquid Wallet Kit)	Wallet creation, address derivation, tx building, signing	Yes
Esplora API	Blockchain queries, tx broadcast, fee estimates	Yes (public or self hosted)
0-Conf	Mempool visibility signal for zero-confirmation acceptance	Optional (swap / low-latency flows)
Waterfalls	Fast wallet sync (single request full scan)	Recommended
AMP2 Proxy	Register wallets and cosign for AMP2 managed assets	Only for AMP2 assets

Understanding Liquid: What Liquid is, why it matters for your business, and how it works under the hood.
Use LWK: Install LWK, create wallets, derive addresses, sync balances, send and receive transactions.
