Progress update on phase 2 -> all code still getting unit tested since I skipped them last time. Have reached 25% code coverage. This time there are two gateways for accepting UPI INR and transferring as sats.

2026-05-12 03:12:31 UTC

The external vendor API service is still down. So @256D cannot function without it. Its been two weeks now. Will keep you updated.
The phase 2 development work is going great. Here #indian merchants will be able to stack #bitcoin sats even from their regular #UPI customers in #india. Few more days for tests before we can open the experiment. Also the phase2 used a different API vendor.

256D users can now also join the telegram group https://t.me/Bitcoin256D for support. Just be careful not to share any personal information within the telegram public group. You can always use nostr DMs here for tracking or any issues.

The phase 2 work is progressing. UPI API is still not working. Hold on.

Yes. That requires a compliance flow coming later.

256D is going down for maintenance. Will be back in two hours.

256D in action. Paying #INR 150 to a Paytm #UPI QR Code by #Bitcoin Lightning in #India. Amazing!

Price of Rs.500 movie ticket, whatever movie hall, 3 weeks back was 8993 sats. this week same thing is 8950 sats.

Would you spend you #bitcoin with 256D in #India if guarantees that price of anything you buy will keep reducing every day? No exceptions, no volatility whatsoever.

Hello folks. Working on a new update where vendors can start collecting #INR #UPI payments. Vendor gets them directly into their #Bitcoin #lightning ⚡ wallet as sats.
This will be huge for all bitcoiners running small businesses, now they can start stacking without any extra work.

2026-02-15 05:14:44 UTC

256D is now officially in @Fedi Mini apps list. Quickly pay the #Bitcoin lightning invoice from within the Fedi app and the following #UPI payment gets transferred .

This is where we are going. Will take most of this year. Small steps.

Hello there 👋
Quick update on the 256D #Bitcoin #INR #UPI bridge:
We’re still down, but real progress has been made with our API provider. We’re now in the final stages of their compliance process. Every step keeps revealing new requirements, so timelines remain tricky to pin down.
We’re pushing hard and will keep you posted. Thank you for your patience — we’re now sure to be back within the next 2 weeks.
Appreciate you sticking with us ❤️

2026-01-30 02:22:13 UTC

The 256D app is down. This is due to vendor Infrastructure not worling. And we dont know when it will be repaired. We are looking for other vendors for payment processing.

Hello day 3 of 256D live. This experiment with UPI connecting with #Bitcoin #LightningNetwork is going wonderful. Thank you for the early feedback from our first users! Amount limits will be gradually relax.

Hello world.
Another #bitcoin product experiment This is from #India.
The first #UPI payment bridge for #LightningNetwork. This will help settle UPI payments instantly at vendors by using #Lightning sats. Simply scan the UPI QR, pay the lightning invoice and instantly the vendor gets his #INR. The web/PWA app is currently in beta, so does not allow large UPI payments. All feedback welcome.

Remember: This is experimental software so use only the funds you're prepared to lose entirely. You have been warned.
