# Setting up Coldcard for use with Casa

Coldcard is one of our **[supported hardware devices](https://support.casa.io/knowledge/supported-platforms-and-hardware-device-firmware?hsLang=en)** for Casa BTC vaults. It does not support Casa ETH vaults.

We recommend a Coldcard Mk4 or higher.

For the latest setup instructions, see **[Coldcard's guide on how to initialize the device.](https://coldcard.com/docs/quick)**
