You can add Sparrow Wallet to the list for Sending :)

I think one of the barriers to greater Payjoin adoption is the need for a
server endpoint on the receiving side. Ideally, all wallets should be able
to conduct Payjoin transactions with each other. This would require a
different mechanism to exchange the PSBTs, but otherwise the specification
should need no amendment. Samourai has implemented their Soroban protocol
to do this over Tor, but as far as I know it's not yet documented.

Given Payjoin is fee efficient (much more so than coinjoin) and relatively
simple to implement, it appears to hold great promise in disrupting
blockchain analysis. I'd love to see a standard that wallets can adopt to
receive Payjoin transactions without a server endpoint.
