How does the Breez SDK - Liquid work?
The Breez SDK - Liquid uses submarine swaps and reverse submarine swaps to send and receive payments, enabling funds to move frictionlessly between the Lightning Network and the Liquid sidechain.
When sending a payment the SDK performs a submarine swap, converting L-BTC from a user’s Liquid wallet into sats on the Lightning Network, and sends them to the recipient.
When receiving a payment, the SDK performs a reverse submarine swap, converting incoming sats into L-BTC, and then deposits them in the user’s Liquid wallet.
