Set up imKey and create its addresses with imToken on your phone first. Use the Rabby Chrome extension 0.92.36 or later and a USB data cable. Enter the PIN on imKey and check the recipient, amount and fee on the device before pressing OK.
Activate and bind imKey in imToken, and save the binding code for a new phone. Allow Bluetooth access; Android may also need location access. Taproot and Native SegWit need imToken 2.16.0 or later and COS 1.9.05 or later. For Bitcoin, imKey displays one default receiving address per account. It does not display every receiving address listed in imToken.
