What’s New with Keystone in 2025?

In 2025, Keystone introduced its Ultimate model, taking security and usability to the next level. The upgraded design features a durable aluminium body, a fingerprint sensor, and an improved touchscreen. Firmware updates have also added passphrase-on-device support and fully customizable workflows for Bitcoin multisig setups — making Keystone one of the most advanced hardware wallets available today.

Core Features

Keystone focuses on uncompromising security while keeping the user experience smooth. Its main features include:

Air-gapped Security: sign transactions with QR codes — no USB or Bluetooth risks.
Open-Source Firmware: fully transparent, verifiable builds for maximum trust.
Touchscreen UI: a large 4-inch colour display makes navigation and confirmations simple.
Multisig Friendly: excellent compatibility with Spectre, BlueWallet, and other Bitcoin multisig tools.
MicroSD Recovery: secure backup of encrypted seed or firmware via MicroSD card.

How It Works

Keystone ensures private keys never leave the device. Transactions are created on your desktop or mobile wallet, converted into QR codes, and scanned by the Keystone device. You confirm directly on the touchscreen before signing. This air-gapped workflow keeps your funds safe from network-based attacks.

Keystone Pro vs Ultimate

Keystone offers two main models to fit different needs and budgets:

Pro: plastic body, excellent value, includes full feature set with QR signing.
Ultimate: premium aluminium build, fingerprint authentication, and longer-lasting battery.
