Crate payjoin

Payjoin implementation in Rust

Important: this crate is WIP!

While I don’t think there’s a huge risk running it, don’t rely on its security for now! Please at least review the code that verifies there’s no overpayment and let me know you did.

This is a library and an example binary implementing BIP78 Payjoin. The library is perfectly IO-agnostic - in fact, it does no IO. The primary goal of such design is to make it easy to unit test. While we’re not there yet, it already has infinitely more tests than the Payjoin PR against Electrum. :P

Additional advantage is it doesn’t care whether you use async, blocking, tokio, sync-std hyper, actix or whatever. There are already too many frameworks in Rust so it’s best avoiding directly introducing them into library code.

To use this library as a sender (client, payer), you need to enable send Cargo feature.

To use this library as a receiver (server, payee), you need to enable receive Cargo feature.
