Your wallet, unlocked by your face.
Marvii is a wallet you open with Face ID or your fingerprint. Let apps act for you, within limits you set, and take that permission back any time.
Three taps. Nothing to write down.
Create a passkey
Face ID, a fingerprint or your screen lock. Nothing to write down.
Approve what the app may do
For example: "Protean may stake and vote for you." Plain words, one tap.
Done
The app handles everyday actions, and network fees are covered.
You hold the key. Apps just get a visit.
No seed phrase
Your key lives in your phone's secure chip. It can't be copied or phished.
You stay the owner
Apps get limited helper keys, never your wallet.
Revoke any time
Take an app's permission back in one tap.
One address everywhere
The same wallet on Base, Monad and HyperEVM. 0x140f…AfDD
No gas to buy
Network fees are covered, so you don't need ETH to get started.
Risky actions need you
Big moves, like treasury transfers or changing settings, always need your tap.
What an app can and can't do
Calm by design
- 01
Passkeys only work on wallet.marvii.xyz, so a fake site can't use them.
- 02
App keys are held by Marvii's signer and boxed in by on-chain rules.
- 03
Built on open-source, audited smart-account contracts (Kernel by ZeroDev).
Let your app request limited, revocable permissions instead of holding user keys.
