# XMR to BTC Atomic Swap
2020-10-07 18:12:17 -04:00
2021-03-04 23:47:16 -05:00
This repository hosts an MVP for atomically swapping BTC to XMR.
2021-03-15 19:28:51 -04:00
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 ).

## Limitations

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

## How it works
2020-10-08 18:34:24 -04:00
2021-03-04 23:47:16 -05:00
This repository primarily hosts two components:
2020-10-07 18:12:17 -04:00
2021-03-04 23:47:16 -05:00
- the `swap` CLI
2021-03-23 04:42:25 -04:00
- the [`asb` service ](/docs/asb/README.md )

### 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
2020-10-07 18:12:17 -04:00
2021-03-04 23:47:16 -05:00
`asb` is short for **a**utomated **s**wap **b**ackend (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 ](/docs/asb/README.md ).
