Working on a Coldcard's PushTX implementation for StartOS:
PSBT ==[SD|QR|NFC]==> COLDCARD signed TXN ==[NFC tap]==> Phone Browser ==> TXN Broadcast to your own node
Discussion
- Created tx in Sparrow
- Scanned using Coldcard Q
- Signed
- Tap my phone on the Colcard
- Transaction published to my node, running on StartOS
(this is on testnet4)
