They hold the power.
Exchanges control your private keys. Apps expose keys to online environments. One breach, freeze, or outage can wipe you out—because the assets were never truly yours.
Take control
with KEYVAULT
Four principles of true self-custody.
Keys stay offline
Private keys never go online. Hackers can't steal what they can't reach.
Verify transactions
Check every transfer on the screen before you sign. Real protection should be visible.

Your questions, answered
Exchanges are already safe. Do I still need a hardware wallet?
Hacks and account freezes still happen. Custody on an exchange means the platform controls your assets. A hardware wallet keeps keys in your hands.
If I lose the device, are my assets gone?
No. Keep your wallet backup (seed phrase) safe and you can fully restore on a new device.
Can I still use DeFi and NFTs?
Yes. Connect major dApps via WalletConnect. Transactions still require on-device confirmation—keys never leave the device.
Is it worth buying for a small amount?
Yes. Crypto is often held long-term, and small amounts can grow. Building self-custody habits from day one is safer.
