Swaps and Bridges
Non-custodial services for swapping between On-chain Bitcoin, Lightning, and Liquid Network (Submarine Swaps).
Swap-Out Service - Building a Reverse Submarine Swap for Lightning Network Channels
This article explains how to build a reverse submarine swap service that moves funds from a Lightning Network channel to an on-chain Bitcoin address in a trustless manner.
