Bundle keys

Derived from your wallet signature. Stored locally.

Key actions are irreversible

Rotating a key re-encrypts the current bundle and invalidates all outstanding access grants. Buyers will lose access until the seller hands over the new key. You will be asked to sign twice before any key-sensitive action proceeds.
