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.

More information about the protocol in this presentation and this blog post.

Quick start - CLI

  1. Download the latest swap binary release for your operating system
  2. Run the binary specifying the monero address where you wish to receive monero and the connection details of the seller: ./swap buy-xmr --receive-address <YOUR MONERO ADDRESS> --seller-peer-id <SELLERS PEER ID> --seller-multiaddr <SELLERS MULTIADDRESS> You can generate a receive address using your monero wallet. The seller will provide you their peer id and multiaddress. We are running an asb instance on testnet. You can swap with to get familiar with the swap CLI. Our peer id is 12D3KooWCdMKjesXMJz1SiZ7HgotrxuqhQJbP5sgBm2BwP1cqThi and our multiaddress is /dns4/xmr-btc-asb.coblox.tech/tcp/9876
  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:

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.

For details on how to run the ASB please refer to the ASB docs.
