140,00 

Coldcard is a well-known Bitcoin-only, air gapped hardware wallet that you can use to store bitcoin.

Description

Coldcard is a well-known Bitcoin hardware wallet. As an air-gapped hardware wallet, Coldcard keeps your private keys completely isolated from the internet. This significantly reduces the risk of theft.

You can connect your Coldcard with a computer via USB, or you can use SD cards in order to take advantage of the Air-gap mode that Coldcard supplies. Like this, you sign your transactions fully offline.

Coldcard Features

The Coldcard hardware wallet is geared towards security-conscious users. It prioritizes security over ease of use, incorporating a tamper-proof design, secure microchip, and air-gapped signing process.

It is a Bitcoin-only wallet with advanced features such as duress wallets, watch-only wallets, 2FA, multi-signature, SegWit, NFC, PayJoin, Taproot, and legacy addresses. Furthermore, it features a USB-C connector, QR code scanner, microSD card slot, and physical keypad.

Notably, it integrates with popular wallets like BlueWallet, Electrum, Sparrow, Specter, and Wasabi.

Although the Coldcard lacks Bluetooth, a camera, a battery, and a mobile app, its emphasis on security makes it a compelling choice if you are seeking maximum protection for your funds. Its price of $157 reflects its advanced security features.
