Unlocking achievements is enjoyable, but earning more interest is even better. So, we arrived at a feature that combined both: Boosts. With boosts, we reward certain actions in and out of the app with bonus APY for a period of time
The first available Boost is called "Refer a friend" and more are on the way. It's super simple: share Donut with your friends, earn +1% APY for 30 days after they make a deposit.
