Introduction

Sign in with Google, Apple, Facebook, or passkeys. No seed phrases. No extensions. No gas tokens to get started. Just log in and you’re ready to trade, swap, send, and interact across Sui, Ethereum, Bitcoin, Solana, and more - all from one place. Behind the scenes, Umi uses Sui as the coordination layer and Ika’s zero-trust technology to give you full custody of your assets. Neither Umi nor the network ever has complete access to your keys. You’re always in control.

Why Umi exists

Most crypto apps force you to choose: easy UX or real custody. Centralized exchanges are simple but you don’t own your keys. Self-custody wallets give you control but the experience is painful - seed phrases, gas on every chain, different wallets for different networks. Umi gives you both. The experience of a centralized app with the security of true self-custody. Your keys are split between you and the Ika network using zero-trust cryptography. Neither party can act alone. Your money stays yours. This is only possible because of Sui. zkLogin removes seed phrases. Sponsored transactions remove gas friction. And Sui coordinates everything across chains so the complexity disappears.
