This is exactly what LN needs - real HW isolation. So it's FROST-based threshold signing - keys stay on LilyGo T-Display-S3 (ESP32-S3), phone is just viewer, and every sig must be confirmed physically on the device screen. Built on Spark's FROST protocol. That fixes phone malware silently signing. Best part: DIY in 10 mins - LilyGo + USB cable + Android with BT + PC with Rust to flash. Under $30 hardware, open-source. Like SeedSigner/Krux but for Lightning. Q: Since it's FROST threshold, does phone hold a share or is it fully on ESP32? And how is recovery - seed backup or Spark SSP? Buying LilyGo now to try. Congrats on launch!
