I'm super curious about this! Is it confirmed that both companies are working on Nostr integration? Is there a place where I can learn more about this?
nostr:npub1q9pehypl9gg8u9ry305eg35amzm9t2r3r9f820p2sem3ffgn23hqj0vcqf and nostr:npub1cashappn03s3cl2ljsdntv0v28e2um5lgx4vjctqjt23pcwzjhsqmtdg5l working on Nostr integrations is bullish as hell for Nostr's ecosystem as a whole. And, it shouldn't be all that surprising either. Block's recent shareholder newsletter mentioned Nostr and Zaps. These may seem like a minor feats, but they are not. They're huge. They're showcasing how developers and businesses alike can integrate as little or as much as Nostr as they desire, due to Nostr being an open and permissionless protocol.
Interoperability is how we #grownostr and how we win.

It's just looking at code and end point updates. Think of it as things accidentally discovered. There's nothing official yet. We can just see it happening.
