Okay we are getting somewhere! A NIP57 zap to my profile shows up in my Olas wallet pretty much instantly. Of course some of the zaps metadata gets lost, but at least the message stays. I will probably add a pointer to the Zap Receipt event in the NutZaps content field.

Bridging the gap between Zaps and NutZaps: nut-bridge!
Nut-Bridge provides a Lightning Address that forwards all received payments via NutZaps to you. With this you can have a nostr-native Cashu Wallet and still be compatible with Lightning-only clients. I had this idea this morning and hacked together an MVP, so be very careful when testing ;)

I saw a few posts here dunking on Dan for his anti-Nostr posts on Twitter/X.
I'm grateful for them. Happy to treat it as a marketing/education opportunity. If life gives you lemons, see if there's a way to make lemonade.

Bitcoin-denominated Cashu tokens have been transmitted via sound, qr codes, stenography, rf radio, satellites in space, nfc cards, bluetooth, emojis, text messages, nostr posts, api calls, and even bank transaction memo fields.
The reason why this is happening is not only because it's extremely fun. It's also because Bitcoin is natively digital money. Bitcoin and the people using it are exploring all possibilities to transact between each other. This is the real digital energy.
Cashu makes Bitcoin light as a feather and transacting with it as easy as it can be. This is what it looks like when a new electronic money is starting to permeate our world. Bitcoin will be literally everywhere and in every corner of the world, just like the internet already is. This is what it looks like when that happens.

Because I received a coupe of DMs pointing out a bug in this code: in JavaScript “this” is implicitly defined in every function scope. If there is no object attached (function is not a method) it points to the global object (window or globalThis).
There is no bug in this code. ecash fixes it globally.

I have spent several weeks trying to replace the Blink API wrapper of npub.cash with a Cashu native alternative and its been a wild ride.
While Cashu mints do support WebSockets for realtime updates, it turned out that WebSockets are pretty difficult to work with, when you are trying to keep them and the subscriptions alive for long periods (in my case days).
But there is a second issue: You see Cashu mints enfore rather strict rate limits on their users. This is important as Cashu is account-less and preventing spam attacks is difficult. Usually this is no issue, as regular users interacting with a mint do not hit these limits. But npub.cash is a funnel. Instead of every user using their own IP to hit the mint, with npub.cash every user "proxies" through the services server.
Turns out this second issue is much

Npub.cash Update
It's been just over eight months since I started working on npub.cash, and it's been an incredible journey! During this time, the project has evolved significantly, with its goals and requirements shifting along the way. Originally, npub.cash was designed as a tool for wallet and Nostr client developers, but it has unexpectedly become a popular day-to-day wallet for many users to receive zaps on Nostr. I absolutely love seeing this, but I must admit that the frontend I built was intended as a demo to showcase how the API could be integrated, not as a fully-featured wallet.
Instead of focusing solely on backend development, I spent considerable time trying to adapt the frontend to this new use case, keeping pace with the rapid advancements in the Cashu and Nostr ecosystems. In hindsight, this was a mistake. Npub.cash functions best when integrated into a comprehensive

Dear npub.cash users,
npub.cash is currently experiencing some issues with all lightning operations. Withdrawals are not affected.
This seems to be caused by a downtime in the Blink API. I will share an update once this has been resolved 💜

I wonder what would be a better way to solve this issue…
npub.cash will hold many many proofs for its users. If someone wants to withdraw, the server needs to send all those proofs over in a big response.
The obvious choice is to run clean up and consolidation jobs that merge proofs together, but once P2PK is adopted this will no longer work (as the server cannot do anything with the proofs)…
I’ll keep thinking about this, but maybe one of you has a bright idea ✌️

PSA: npub.cash just had a small change in its public API!
While /claim used to return a token containing all pending proofs, it now returns a token containing max. 100 proofs! Additionally there are two new keys in the payload:
- count: how many proofs are included
- total pending: how many proofs are pending in total for the user
This change makes sure that the token does not get too long for handling it and lets API users now if there are more proofs pending.
I am not perfectly happy with this yet and I will continue looking into other ways to handle these edge cases. 🫡💜

After being delayed for over a week I finally managed to finish the new release for npub.cash. It is now in staging and if everything goes as planned I will manage to release it tomorrow.
This release took a while to complete, because it changes the way how the server keeps track of the token spending-state. It used to check all pending claims all the time when user accessed the wite, which cause much traffic for mints and also caused issues when users had many proofs pending (Some had over 1000...)
npub.cash will now assume a token as spet as soon as you create the token / qr code. If anything goes wrong, you can resurface the token at any time from your withdrawal-history tab.
Also npub.cash will check how many proofs are pending and will paginate the result if there are too many.

Pretty close to releasing the biggest update to npub.cash so far.
Most changes are under the hood, optimising the way npub.cash handles token state in order to reduce the amount of requests.
Also I am adding support for nostr-based cashu wallets like nutsack 👀 Users will be able to withdraw their balance to their nostr-cashu-wallet. Furthermore you can setup a "redirect" so that all transactions land in your nostr-cashu-wallet automatically, essentially adding a npub.cash address to every nostr-cashu-wallet out there.
These changes do not only require a lot of work on npubcash-server, but also on the website and the SDK. I hope to get it out by early next week 💜

Thanks to @Rusty Russell calling me out on the ease of use of npub.cash, I am working on a OTP type login.
The user will enter their pubkey to login. The server generates an one-time-password and send it to this pubkey in an encrypted DM. The user can then enter the OTP in the browser window and obtain a session token.
This will dramatically increase the UX on mobile devices and offer a more sure way to login vs. raw nsec.

Doxxing an anonymous developer is a disgraceful act and has no place in investigative journalism. It's simply wrong, especially when the intent is to undermine an open protocol that champions free speech and its supporters.
This is an attack on the freedom of speech and the right to privacy. Everyone involved in this article should be ashamed of themselves.

I recently started to invest a lot of time in the npub.cash testing suite. It's a painful process as I am still new to test design and the original code was strongly coupled, but I am getting there.
Vitest comes with a UI that will let you inspect not only coverage, but also your codes module graph, which is a great help when trying to decouple.

I switched to a ortho/ergo split keyboard with 36 keys two weeks ago and I absolutely love it.
It forced me to drastically improved my touch typing. After two weeks I am now back at 55 wpm, but I feel like the ceiling got raised quite a bit and I should be able to hit 70wpm soon. Navigation is also quicker because mods are very easily reachable and even harder combos like Option + CTRL + Shift + 2 (My window manager uses that one) are a breeze.
My posture has improved greatly. It’s way easier to sit straight when your arms are body wide apart and not cramped right in front of you. Of course my wrists are straight and there is no reach (I use a reduced layout where the outer most column is unused so every key is maximum one key away).

It can be used to encrypt / decrypt messages (for e2ee messages like email), but also for signing data. For example code I commit to repositories is signed using my gpg key. If you want to verify that a commit was indeed pushed by me, you can verify the signature on it.
Many developers sign their releases as well. For example when you download Sparrow Wallet you can get an additional signature file to verify that the release was indeed created by @craigraw
