Note: Please keep your backup mnemonic phrase safe. The correct way to back it up is using physical media, such as writing it down by hand on a piece of paper or using a imKey HeirBOX Mnemonic Storage. Because these physical media cannot be connected to the internet or transfer information between electronic devices, they can truly save your mnemonic phrase offline.
