Are my keys ever at risk?

No — your private keys are never at risk.

When you use Prove, you sign a message with your wallet or device to verify ownership of your Bitcoin. This is a standard process called message signing, supported by most wallets and hardware devices. It's secure, non-invasive, and keeps you in full control.

At no point do we ask for or have access to your private keys. You approve the signature from your wallet or device, and that’s it. Nothing sensitive is ever shared with us.

We don’t take custody. We don’t initiate transactions. And we never see your keys.

Your device stays your device.
