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.
