Identity

One signature. Every device. Every chain.

Your wallet is your account. A single signature unlocks Sudo on macOS, Windows, Linux, iOS, Android, and the browser. Lose a device and the keys never left it.

Multi-device E2EE sync via per-device subkeys
Hardware wallet & multisig sign-in supported
Per-app spending limits — apps can't drain you
Optional .sudo username NFT for human-readable identity

Mint a username NFT

What's in the box

Everything you'd expect — and a lot you wouldn't

Wallet sign-in

End-to-end encrypted

Messages encrypted on your device using libsignal — even Sudo cannot read them.

Resolves any address

ENS, Lens, .sudo, Farcaster, Unstoppable Domains, Basenames — paste any handle, we'll route the message.

Token-aware chat

Drop tokens, NFTs and contract calls into any message — settled on the chain you choose.

Spam-resistant

First DM costs a tiny gas-only stake — bots vanish, friends arrive.

Cross-chain rooms

Channels that aggregate identities across L1s & L2s into a single conversation.

How it works

From signature to first message

No sign-up form. No verification email. No 6-digit code. Just a quick signature and you're in.

01
Connect a wallet
Tap Connect and pick MetaMask, Rainbow, Coinbase or any WalletConnect wallet. Sign a Sign-In-with-Ethereum challenge — gas-free.
02
Generate session keys
Sudo creates a per-device encryption key under your wallet, signed once. Keys never touch our servers.
03
Resolve your contacts
We index any wallet you've ever transacted with, resolved against ENS, Lens, .sudo and friends. You pick who to message.
04
Send & earn
Type, ship a payment in-line, react with an NFT. Eligible interactions mine SUDO into your wallet automatically.

Wallets supported

Bring the wallet you already trust

Sudo never asks you to migrate, import a seed, or hand over a private key. We support every major signer over WalletConnect v2 — including hardware wallets and Safe multisigs.
