XMR to BTC Atomic Swap

This repository hosts an MVP for atomically swapping BTC to XMR. It implements the protocol described in section 3 of this paper.

Quick start

  1. Download the latest release for your operating system
  2. Run the binary: ./swap buy-xmr --receive-address <YOUR MONERO ADDRESS>
  3. Follow the instructions printed to the terminal

Limitations

For now, the MVP is limited to testnet3 on Bitcoin and stagenet on Monero.

How it works

This repository primarily hosts two components:

  • the swap CLI
  • the asb service

swap CLI

The swap CLI acts in the role of Bob and swaps BTC for XMR. See ./swap --help for a description of all commands. The main command is buy-xmr which automatically connects to an instance of asb.

asb service

asb is short for automated swap backend (we are open to suggestions for better names!). The service acts as the counter-party for the swap CLI in the role of Alice. It provides the CLI with a quote and the liquidity necessary for swapping BTC into XMR.
