# HD Wallets Overview

The Komodo DeFi Framework now is able to activate coins in Iguana and HW modes simultaneously!

For example, you can activate RICK with seed phrase private key like usual, and also activate MORTY with Hardware wallet at the same time.

To get started, configure and launch the Komodo DeFi Framework, then plug in your Trezor hardware wallet device.
