Bisq2: Liquid Wallet Integration (Elements)

[alvasw]

This is a Bisq Network project. Please familiarize yourself with the project management process.

Description

We want to implement atomic swaps between Bitcoin and L-BTC/Liquid Assets in Bisq 2. To do that, we need to implement a Liquid Wallet backend first. In this project, I'll implement the backend for the Elements Wallet (https://blockstream.com/elements/).

Rationale

This is needed to implement atomic swaps between Bitcoin and L-BTC/Liquid Assets.

Criteria for delivery

This project is complete when the needed RPC calls to Elements are implemented and merged into Bisq 2 (including integration tests).

Measures of success

We have a liquid wallet in Bisq 2.

Risks

None.
