  1. 🔐Chosen Features

Emergency Lockdown Button

To defend against attacks where the user is physically coerced, the Casa app features an Emergency Lockdown Button. Once activated on the mobile app, all functions that depend on the Casa app or the Casa API will no longer function. This prevents the app from making new transactions or from using the Casa signing portal to add a signature to an existing transaction. The lockdown can only be removed by a customer service representative after the customer requests a removal of the lockdown and the representative verifies the customer’s identity.

It is important to note that the Emergency Lockdown can never be used to block a client from making transactions because our clients always control the majority of keys. When the Emergency Lockdown is activated, a client can still access their funds using Electrum or other software.
