This is super interesting! What do I need on client side to use it? Is a LoRa connected Android phone able to post through this gateway?

2026-03-28 16:03:16 CET

- reply

Yes, with signalling over Nostr.

2026-03-28 11:52:22 CET

Yes, voice and and video calls are planned. But signalling over Nostr is a bit tricky.

You're correct, this should be NIP-55. All good.
I added some safeguards to the initial history sync. If you want you can test them now on the web version: https://nospeak.chat
Android will follow in next version.

2026-01-12 14:00:54 CET

- reply

You can use Amber as a remote signer (NIP-46) or offline / same device (NIP-55). Only the NIP-55 variant is fast enough to decrypt a large quantity of messages. I just checked: It decrypted about 1000 messages in 40 seconds for me.

2026-01-12 13:43:01 CET

- reply

Ah, makes sense. :) I'll build in some safeguards to the initial sync which lets the user skip the full sync if he wants to. Next version - I'll ping you.
For Amber: Can you try the offline Amber? I use it and it's superfast.

2026-01-12 13:00:54 CET

- reply

This is fixed now. Next version will have it.

2026-01-12 11:33:07 CET

Hey Derek! 10 minutes are by far too long. It should load history messages for 1 month in this stage. Could it be that one of your messaging relays was slow at this time? Otherwise try to logout (settings/security) and try again.
- Do you have a lot of NIP-17 messages?
- Are you using Amber over relays? (that will be very very slow)

2026-01-12 11:25:35 CET

Hey, nice find! That will be easy to fix. Stay tuned for v0.9.22

Happy new year!
I created a new Nostr based messaging client over the last weeks: nospeak. It supports NIP-17 completely (messages, file messages and reactions), but only 1-on-1 now.
Platform is either Web/PWA or Android. The Android app uses an own background notification task which works fine and (I hope) does not stress the battery too much.
It has NIP-05 verification for users, Blossom support for encrypted media and profile images, location sharing and much more.
Login is possible via NIP-55 (Amber), NIP-07 signer or NSec.
Check it out here:
https://nospeak.chat
Android app via Obtanium, Zapstore or GitHub directly. F-Droid is waiting for review.
Github: https://github.com/psic4t/nospeak
Test it a bit and write with me if you want. 😃

Anyone here with deeper knowledge of #LND? My lightning node can't send payments to Alby and says "no_route" all the time. My node is well connected to large nodes so that should not be an issue.
How can I debug this? The "no_route" error appears imedately - maybe some weird caching issue? Restarting LND didn't help.
