Casa Multi-Signature Cold Wallet
I am interested in knowing if anyone has ever used the Casa Multi-Signature Cold Wallet. At the most basic level, this system uses three keys in the form of:
1. Key #1 – Held by you via your own storage device (i.e. Ledger, Trezor, Cold Card, etc.);
2. Key #2 – Held by you via your mobile phone’s Casa application/program; and
3. Key #3 – Held by the company Casa themselves.
What has your experience been using Casa? What are the risks (i.e. Casa becomes bankrupt, Casa loses your third key, Casa does not respond to your request to give you your third key, etc.)? What do you recommend?[https://keys.casa/services/multisig-wallet-casa/](https://keys.casa/services/multisig-wallet-casa/)
Seems to me like you only truly own one key and the other 2 belong to Casa, no? Can you extract the key from the application on your phone?
