Part 3/10:
How to Enable Tap-to-Broadcast:
Navigate to Settings > Hardware On/Off > NFC Sharing.
Select Enable NFC.
Further down, select NFC Push Transaction.
Choose your relay method—mempool.space is a popular, easy-to-use option—or input a custom relay URL.
Practical Use:
Enabling this feature allows you to sign a transaction on Sparrow Wallet, generate a QR code, and then broadcast it by tapping your NFC device. This process significantly reduces transaction time and minimizes manual steps, especially useful when speed is crucial or if your device's camera isn't optimal.
Example:
Create a transaction in Sparrow Wallet.
Tap "Show QR" to encode the transaction.
Use the Cold Card Q's QR scanner to sign.
