BlueWallet and ColdCard seem to go together like Peanut butter and jelly, Kool-Aid and water, or even Ham and Cheese. It’s super simple to manage Multisig from your mobile device while having the security of cold storage. Has anyone else put together a better setup than these two tools, especially for a Multisig for a family-office or small business? Let me know!

Almost forgot! The icing on the cake is connecting this setup to your own Bitcoin node on Umbrel, and verifying transactions using Mempool.
