Delta chat does this, without the micropayment.

I wonder if one could run Delta Chat on top of yggmail[1] (very much an alpha software release) for a truly P2P IM chat. yggmail runs over IPv6 with a tun interface same as yggdrasil. Might test this out at some point for fun.

Not quite the discoverable, user-friendly experience of Briar, Bitchat etc. but it can be combined with online links (Briar can technically go online, but only via Tor; both Briar and Bitchat are only for smartphones).

Delta Chat can already run on top of iroh [0]. No need to find some other server implementation - it can already do "truly" P2P - devices can end up running their own STUN and TURN servers, etc.

Delta Chat can transfer messages using a Bluetooth Mesh Network? That's new to me.
