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. 417: Bump curve25519-dalek from 3.0.2 to 3.1.0 r=thomaseizinger a=dependabot[bot] Bumps [curve25519-dalek](https://github.com/dalek-cryptography/curve25519-dalek) from 3.0.2 to 3.1.0. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/dalek-cryptography/curve25519-dalek/blob/main/CHANGELOG.md">curve25519-dalek's changelog</a>.</em></p> <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.

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
- Download the latest
swap
binary release for your operating system - 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 anasb
instance on testnet. You can swap with to get familiar with theswap
CLI. Our peer id is12D3KooWCdMKjesXMJz1SiZ7HgotrxuqhQJbP5sgBm2BwP1cqThi
and our multiaddress is/dns4/xmr-btc-asb.coblox.tech/tcp/9876
- 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.
For details on how to run the ASB please refer to the ASB docs.
