Maximum Wallet Security Part 2: Improving Casa Multi-Sig (Watch Only , Sovereign Recovery, Coldcard)

This video runs through how to create both a watch-only wallet in Electrum (Allowing for address verification), how to fully recreate a working wallet in Sparrow and how to fully register the multi-sig wallet on a Coldcard (Full hardware address verification). This basically uses the documentation from Casa for Sovereign Recovery and also looks and some small bugs and issues that you might strike trying to do this. (Particularly with a Coldcard) Overall, re-creating your wallets like this can not only give you maximum security, but also help you understand how all the tools work so that you are better equipped to secure your wallet and possibly move to a DIY multi signature setup.
