LNbits Nostr Signing Device. Working on my 3rd PR which supports signing over BLE 😁👍
Very interesting sir.
Keep building. 💪
What is BLE? Like Bluetooth?
niiice
Bluetooth Low Energy
😍
New Bluetooth-based signing devices need a NIP for their BLE protocol, but otherwise 🚀
Oh man! This is fun.
Pra que serve isso?
That's cool 😎, what exactly does it do?
It holds your nostr private keys and allows you to sign notes and encrypt/decrypt them from a client which only has the public key. The current version only supports over USB but this build does it over BLE too.
That sounds dope 😎
Great job! I have two of these devices lying around, it would be excellent to turn them into signers.
Check out this PR that implements support for the T-Display-S3. This build doesn’t implement BLE, but I’ll be raising that PR next.
