# 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](https://arxiv.org/abs/2101.12332) paper.

More information about the protocol in this [presentation](https://youtu.be/Jj8rd4WOEy0) and this [blog post](https://comit.network/blog/2020/10/06/monero-bitcoin).

Currently, swaps are only offered in one direction with the `swap` CLI on the buying side (send BTC, receive XMR).
We are working on implementing a protocol where XMR moves first, but are currently blocked by advances on Monero itself.
You can read [this blogpost](https://comit.network/blog/2021/07/02/transaction-presigning) for more information.

## Quick Start

1. Download the [latest `swap` binary release](https://github.com/comit-network/xmr-btc-swap/releases/latest) for your operating system.
2. Find a seller to swap with:

```shell
./swap --testnet list-sellers
```

3. Swap with a seller:

```shell
./swap --testnet buy-xmr --receive-address <YOUR MONERO ADDRESS> --change-address <YOUR BITCOIN CHANGE ADDRESS> --seller <SELLER MULTIADDRESS>
```

For more detailed documentation on the CLI, see [this README](./docs/cli/README.md).

## Becoming a Market Maker

Swapping of course needs two parties - and the CLI is only one of them: The taker that occasionally starts a swap with a market maker.

If you are interested in becoming a market maker you will want to run the second binary provided in this repository: `asb` - the Automated Swap Backend.
Detailed documentation for the `asb` can be found [in this README](./docs/asb/README.md).
