Will the compound finance cannot connect my wallet after use mobile version ? Thank you.
You'll need to save / backup your seed words (12 random english words that are in your Metamask settings) from your desktop, and import them into your mobile metamask.
Better yet, ask Compound to support a web wallet that is backed up remotely (e.g. Portis, Fortmatic, Torus, or Democracy)
