Emergency Recovery Key
In order to reduce the chance of user error leading to the loss of funds, Casa holds one of the signing keys in the user's multisig setup for use only in emergency recovery scenarios. The recovery transaction is used to transfer the client's funds to a new key set.
Casa will only use the Recovery Key after a client has verified private data that they provided to us during setup. This signing of a single Recovery Key must be combined with enough signatures from the client to complete a recovery transaction. This ensures that Casa (or a malicious actor attempting to compromise Casa) can never block or access client funds.
