nostr Still in the danger zone but you can issue your own payment card. #nostr #safebox… Tim Bouma Jun 4, 2025, 1:00 PM
nostr Here is a close-up demo of the nfc payment. Still lots of dev cruft in the UI but bear with me. The wallet holder presses Pay with NFC, the payer taps their card (not shown). The payment amount and card data is sent for processing. The wallet returns to… Tim Bouma Jun 4, 2025, 12:23 PM
nostr This also looks super similar to the Bolt Payment Cards. I recall playing around with those schemes a few years ago. In essence, a Bolt Payment Card is linked to someone else’s accounting system storing your funds. Although it looks the same and the Bolt Payment Card, this scheme… Tim Bouma Jun 4, 2025, 11:41 AM
nostr This payment scheme approach has been long established. It used to be called ‘tokenized payment scheme’, until the word ‘tokenized’ became stupid. The most important part of the scheme is that the payer can be ‘offline’ - so long as the acquirer can get the data, they can fire it off… Tim Bouma Jun 4, 2025, 11:27 AM
nostr For the user, this will look like a boring tap payment at a terminal with their card. Behind the scenes, it’s an unsurveillable private payment system using the Lightning network with funds blindly transferred using native ecash wallets. The user issues their own payment card for the network. No. Tim Bouma Jun 4, 2025, 10:01 AM
nostr Proof of work. Payment of 21 sats using NFC card on Android with #nostr #safebox on left. Updated balance and transaction are shown in Nostr Wallet Connect in #damus iOS client on right. Instantaneous.… Tim Bouma Jun 4, 2025, 3:52 AM

nostr Well, holy shit I got nfc payment working end to end with Nostr Wallet Connect! The #nostr #safebox issues a payment card - an encrypted payment token that is written to a nfc card. When that card is read by another wallet, it generates the lighting invoice, extracts the vault url, Tim Bouma Jun 4, 2025, 3:00 AM
nostr Payment by NFC with #nostr #safebox I have the secure plumbing figured out. Still more to implement but here is the gist: Reader acquires encrypted token from card and amount Generates lightning invoice. Acquited sends encrypted token and invoice to token vault endpoint Vault decrypts token and issues nwc command… Tim Bouma Jun 3, 2025, 6:53 PM
nostr I’m excited about this next mini-project of mine for #nostr #safebox. I’ve been studying card payment networks, specifically, how a digital copy of your payment card gets into your Google, Apple or Samsung Wallet. I have the same card in three different wallets and wondered how that… Tim Bouma Jun 3, 2025, 10:21 AM
nostr Now that I've tackled a critical bug, I'm starting to take the training wheels off. I am now keeping amounts of cash that I would typically have in my day wallet. #nostr #safebox… Tim Bouma Jun 2, 2025, 7:59 PM

nostr Putting this out there… Following from what I’ve learned from @nosfabrica , I am planning to do a Community Pilot,in late 2025 or early 2026. I am looking for a community who wants to use #nostr #safebox in a healthcare setting. Physicians who want to issue health records to… Tim Bouma Jun 2, 2025, 4:04 PM

nostr Yup. And the two really boring things I am implementing behind the scenes for #nostr #safebox that users won’t care about until they need to care about. A constrained custodial option, that not even the service provider can access or see the user data, if they get tapped on… Tim Bouma Jun 2, 2025, 12:48 PM
nostr People just take for granted that their emails go to their inbox. People should also take for granted that their emergency funds and important records should be stored in their safebox. This is what I am trying to build with #nostr #safebox… Tim Bouma Jun 2, 2025, 10:38 AM

nostr Yeah, this is super-cool. I can do this with #nostr #safebox - the lightning address is also a NIP-05 address so you can send cashu tokens directly to another #safebox. I also plan to make this capability completely invisible to the user - the sending safebox determines that the lightning… Tim Bouma Jun 1, 2025, 12:02 PM
