## What is Zengo

Zengo is a self-custodial mobile crypto wallet for iOS and Android that replaces the seed phrase with MPC (multi-party computation): the signing key is split into a share on the phone and a share on Zengo's servers. It is made by Zengo Ltd. and has operated since 2018.

## How voting works

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
