Simplify code within BobState::XmrLockProofReceived 
To achieve this, we decompose `watch_for_locked_xmr` into two parts:

1. A non-self-consuming function to construct a `WatchRequest`
2. A state transition that can now consume `self` again because
it is only called once within the whole select! expression.

Ideally, we would move more logic onto this state transition (like
comparing the actual amounts and fail the transition if it is not
valid). Doing so would have an unfortunate side-effect: We would
always wait for the full confirmations before checking whether or
not we actually receive enough XMR.

This allows us to have state transitions that consume self.

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.
