408: Improve error reporting of failed protocols r=thomaseizinger a=thomaseizinger

Instead of forwarding every error, we deliberately ignore certain
variants that are not worth being printed to the log. In particular,
this concerns "UnsupportedProtocols" and "ResponseOmission".

To make this less verbose we introduce a macro for mapping a
`RequestResponseEvent` to `{alice,bob}::OutEvent`. We use a macro
because those `OutEvent`s are different types and the only other
way of abstracting over them would be to introduce traits that we
implement on both of them.

To make the macro easier to use, we move all the `From` implementations
that convert between the protocol and the more high-level behaviour
into the actual protocol module.

<blockquote>
<h3>3.1.0</h3>
<ul>
<li>Add support for the Elligator2 encoding for Edwards points.</li>
<li>Add two optional formally-verified field arithmetic backends which
use the Fiat Crypto project's Rust code, which is generated from
proofs of functional correctness checked by the Coq theorem proving
system.</li>
<li>Add support for additional sizes of precomputed tables for basepoint
scalar multiplication.</li>
<li>Fix an unused import.</li>
<li>Add support for using the <code>zeroize</code> traits with all point types.
Note that points are not automatically zeroized on Drop, but that
consumers of <code>curve25519-dalek</code> should call these methods manually
when needed.</li>

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-multiaddr <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 /dns4/xmr-btc-asb.coblox.tech/tcp/9876
  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.
