What is the 21 app?
The 21 app is an interface that gives anyone access to DeFi strategies, without handling the technical steps themselves.
Decentralized finance opens up access to financial products that used to be reserved for institutions.
1/3
Using them still takes wallets, networks, signatures and constant monitoring.
At 21, we believe DeFi should not be this complicated. With our app, you choose a strategy and invest in a few clicks. Your funds stay in an account you own. We document, you decide.
2/3
Two USD savings strategies. Instant withdrawal. No minimum.
The 21app is now in beta.
