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
What's in the box
Everything you'd expect — and a lot you wouldn't
Wallet sign-in
Sign in with Ethereum (SIWE) or any WalletConnect-compatible wallet. No email, no phone number, no custody.
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.
Privacy by default
Messages are encrypted on your device with libsignal. Sudo operates the relay; we cannot read your conversations.
Account abstraction ready
ERC-4337 smart wallets and session keys mean you can sponsor gas, bundle actions and onboard non-crypto friends.
