How to add and use Taproot and other Bitcoin address types in imKey hardware wallet?

In imToken version 2.16.0, the imKey hardware wallet officially supports Taproot and Native SegWit Bitcoin accounts. Before making transfers with these accounts, please ensure that the imKey firmware is upgraded to version 1.9.05. For detailed information on the firmware upgrade process, please refer to imKey Manager User Guide: How to Perform COS Upgrade.

Note: When creating or importing a Bitcoin wallet, the default address type is Taproot, with the derivation path m/86'/0'/0' (starting with "bc1p"). After adding an account, you can choose other address types based on your needs (Legacy, Nested SegWit, or Native SegWit).

How to Reconfigure the Device After the Firmware Upgrade?

1. Open your phone settings, go to the "Bluetooth" option, find the corresponding imKey device name, and tap "Forget this Device."
2. Open the imToken app and re-pair the imKey device. If you are prompted with "Device pairing information has changed, please unpair first, and then re-pair it.

• Bitcoin tokens are not interoperable between different address types. If you need to transfer assets between different address types, simply do so through a standard transaction.
