description Keystone Overview

Keystone is a unique hardware wallet that operates as an air-gapped device. It does not connect to the internet via Bluetooth or USB; instead, it communicates with your computer or phone using QR codes. This 'air-gap' provides a high level of security against remote hacking. It features a large screen and supports a wide range of assets, making it a favorite for those who want maximum isolation without sacrificing usability.

help Keystone FAQ

Is Keystone a cryptocurrency exchange?

No. Keystone is a hardware wallet, not an exchange, so it is used to store and sign crypto transactions rather than to trade order books. Its key selling point is air-gapped QR-code signing.

What does air-gapped mean on a Keystone wallet?

Air-gapped means the wallet is designed to avoid direct USB, Bluetooth, or Wi-Fi transaction connections. Keystone devices typically sign transactions through QR codes shown between the wallet and a companion app.

Can Keystone work with MetaMask?

Keystone has promoted compatibility with MetaMask for Ethereum-style wallets through QR-based workflows. That makes it useful for DeFi users who want hardware-wallet signing without plugging the device into a computer.

How is Keystone different from Ledger or Trezor?

Ledger and Trezor commonly use USB, and some Ledger models also support Bluetooth. Keystone's main distinction is the QR-code air-gap approach, which appeals to users worried about remote connection attack surfaces.
