Spend from wallet that does not pick up transactions 
The code on this branch was used to publish a transaction that spends from a wallet that was created during a swap using `generate_from_keys` but did not pick up the lock transaction of the swap correctly. The transaction could be decoded properly with the view-key, so for now we assume there must be a problem in the `monero-wallet-rpc` when handling certain wallets. Further investigation is needed to reproduce this problem.
This branch was used to spend them the lock transaction, to validate that the transaction can be spent. This was successfully achieved, however, the spending transaction that was published is unfortunately faulty (there is a problem with the outputs). The monero daemon accepted and included the transaction, but the monero wallet (through `monero-wallet-rpc`) is unable to process the transaction properly.

Original Monero Stagenet lock transaction ID: `09e361acb3e6e71d627a945a30672776a6f8fec7c97f4cae5e09b0780b75c158`
Stagenet Transaction ID that spends from the lock tx (the tx published through the integration test on this branch): `f111e906fd4ea3c25ae34d5c8ec68342bbed258c546ce74a839e14f34b591641`

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-addr <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 /dnsaddr/xmr-btc-asb.coblox.tech
  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.
