am somewhat concerned that some payjoin implementations are written in JavaScript and would benefit most from a v2 upgrade in order to support receiving, but no JavaScript ur library exists yet. Perhaps one could be bound from the rust implementation.

There is some progress here, including our reference library in Typescript for dCBOR and UR-based Envelope, but hopefully we will expand soon to offer it in reference libraries, though some will have to be wasm of our rust code.

I've heard that there are some wallets using URs written Javascript, but they have not announced open source libraries yet.
