The Zengo Wallet is a smartphone crypto wallet that works without a seed phrase. Instead of a private key that you have to write down as 12 or 24 words, Zengo creates two separate key shares: one sits on your phone, the other on Zengo's servers. A transaction is only created when both shares compute together, without either ever seeing the other. This technique is called multi-party computation, or MPC.
For you, that means less paperwork but a different kind of dependency. You hold your coins yourself, but to recover them you need your email address, a file in your cloud and Zengo's servers. This guide explains exactly how that works, what it costs and where the limits are. Our software wallet comparison shows the alternatives.
