DAU Key is an innovative hardware cold wallet that is powered by Tangem, which you can use with the DAU Vault application for receiving, storing and transferring your digital assets on blockchains. The DAU Vault application is equivalent to MetaMask wallets, which support both hot and cold wallets, while DAU Key is the cold wallet, equivalent to a Ledger hardware device.

DAU Key looks similar to a bank card, which stores your private keys to your digital wallets. Unlike other hardware wallets like Ledger:

• You don't need to use a cable to connect it to the interface platform, but simply by tapping it to your phone using the NFC module when authorising a transaction or other sensitive actions.

• It is extremely resistant to dust, water, and extreme temperatures.

• There is no "recovery phrase” required which could inadvertently result in loss of your assets.
