Your keys, anywhere.
The KeepKey companion app lets you view your portfolio and review requests from anywhere — every transaction is confirmed on your KeepKey, where your private keys stay locked.
Mobile visibility.
Hardware control.
Everything the app does, your hardware device approves. You can see everything. Nothing moves without your KeepKey.
Portfolio at a glance
See your full balance across every chain in one view — BTC, ETH, Cosmos, and more. Always current, never custodial.
Review requests
Initiate and review requests on your phone. Every transaction is confirmed on your KeepKey device — the phone never signs.
Watch-only mode
Monitor any address without connecting hardware. Track holdings, incoming transfers, and historical activity read-only.
Open source
Every line of the mobile app is publicly auditable on GitHub. No hidden telemetry. No vendor lock-in.
Clean. Focused. Secure.
Self-custody in your pocket.
Monitor balances and stay connected to your portfolio from anywhere. Your keys remain on the device. Always.
