Not on Nostr, and not decentralized :)
Yet.

Yep. Yet. I believe its heading that waysoon tho for both.
How about building a Bisq like Bitcoin/Fiat on-ramp on top of Nostr? https://n3xb.io
Sounds great. Centralised tho?
Basically a giant global & open order book shared through Nostr relays. Meant to be a protocol so anyone can build a client and interop on an open global liquidity pool. Just like Nostr, and as decentralized as the Nostr architecture allows.
Also realised bisq sort of does this but not really!!
This is really just Bisq and RoboSats onto an open protocol and an open liquidity pool. Instead of pure P2P it becomes a Nostr relay based architecture. The problem with pure P2P is it requires the peers to be always on - this makes mobile usage impossible.
The problem Nostr solved is allowing relays to just be a dumb information hub as so things won’t be centralized, but still allow clients to come on only when the user demands - which is critical for mobile usage.
