Monarch wallet is a multi-cryptocurrency, non-custodial wallet. It is available for major mobile operating systems and desktop Windows and Mac OS. The wallet offers a form of staking which they call interest accounts. Users can deposit an amount of a specified cryptocurrency and get interest, at a specific rate. Each coin has a different interest rate.
The wallet supports many coins, including all ERC20 tokens. Much of those coins too are available for earning interest for holding on Monarch. The user experience is good enough but the user interface is what i am not much of a fan of. The wallet has a 4/5 rating on google play store with over 50k installs so its trusted by a good number of people.
