542: More resilient `MoneroWalletRpc` startup in the harness r=da-kami a=da-kami

Recently we se this problem on CI quite often:

```

May 27 01:27:00.858  INFO testcontainers::core::wait_for_message: Found message after comparing 2 lines

May 27 01:27:14.482  INFO testcontainers::core::wait_for_message: Found message after comparing 16 lines
thread 'alice_punishes_after_restart_if_bob_dead' panicked at 'called `Result::unwrap()` on an `Err` value: error sending request for url (http://127.0.0.1:49177/json_rpc): operation was canceled: connection closed before message completed
```

Given the message `connection closed before message completed` it is likely that the `monero-wallet-rpc` is not fully started yet.

Unfortunately we cannot wait to see a different message in the logs upon container startup, because there are just no further deterministic messages after the one we are currently listening on.

To overcome this problem without extending testcontainers we introduce a retry mechanism when creating the wallet.

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

From version 0.6.0 onwards the software default to running on mainnet. It is recommended to try the software on testnet first, which can be achieved by providing the --testnet flag. This quickstart guide assumes that you are running the software on testnet (i.e. Bitcoin testnet3 and Monero stagenet):

  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 --testnet 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

For running the software on mainnet you just omit the --testnet flag. Running on mainnet will automatically apply sane defaults. Be aware that this software is still early-stage. Make sure to check --help and understand how the cancel and refund commands work before running on mainnet. You are running this software at your own risk. As always we recommend: Verify, don't trust. All code is available in this repository.

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.
