Building https://npub.cash 🥜 Working on awesome nostr, cashu and Lightning stuff 💜⚡️

This is one of the coolest nostr related things that I have seen in a long time! Cant wait to play around with it! 🔥🥜 nostr:note1u3qvwqcdtf0fwv0lxt3rd6tfkjlye8rkl3gdw3zrevlhmqa378sqhex7ht

Thank you 🙏 TBF reading through cbor-js code base and a long conversation with ChatGPT about bitwise operators was a huge help though haha

We are so close to finally (after months) release Cashu-ts v1.0

If you use Cashu in your JavaScript / TypeScript project, please do me a favor and test the latest RC.

https://www.npmjs.com/package/@cashu/cashu-ts

That would be really cool! Bring her along

I understand that. What exactly is missing to make it a delight? DMs doesn’t count, as it’s not part of the API ^^

npub.cash does not do this, because I did not get to implement it yet.

Also it was always meant to be an API service that is more hidden from the user. Like giving a Lightning address to a Cashu wallet and claiming the nuts automatically

This is the first time in a couple of years that I set up an nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct and I have to admit that this is pretty close to top-tier UX. If all Bitcoin apps / tech feel like this in a couple of years, I am not really worried about the entry barrier at all.

I built a thing 🙌🏻 Did actually expect this to come out as nice as it did.

Helped a friend of mine with some photos for his restaurant…

What a pleasure 👀🥩

I paid my first BOLT12 offer in 2021… C Lightning already had it back then.

What’s with the recent hype?

Great idea! Especially when most zaps are from custodial wallets 🤡

Not a fan of using general purpose hardware for my savings

Actually I always thought the same. However when trying the Safe 5 I noticed that for a touch screen to properly work it needs to be big enough aswell. I really didn’t like the Safe 5 UX.

Maybe this could be something for a larger future model though

This dev device accepts custom firmware… I don’t know much Rust, but I guess I could make it create schnorr signatures on arbitrary data.

Arbitrary data like nostr events, or Cashu token đź‘€ nostr:note18qc0qzz2f83f6cmh2pex2yecthj6t3g98q50y7gca6dd8wrfpyrsjsqm0s
