Bitcoin Plebs: Coldcard really fucked up. I want a simple way to store my Bitcoin using a multi-vendor setup that requires approval from two different hardware wallets - especially for the stash I'm not planning to touch for the next 10 years.

Bitcoin Devs: You should use a 4-of-5 multisig where one of the keys is held by a third party, with a Miniscript decaying timelock that switches to a 2-of-5 policy after six months. Just remember to rotate the UTXOs every ~5 months. Oh, and use Taproot to obfuscate the full vault mechanism - most hardware wallets already support it.
AND DON'T FORGET TO BACK UP THE DESCRIPTOR. YOUR FAMILY WILL NEED IT IF SOMETHING HAPPENS TO YOU!

For simple + two vendors: 2-of-3 multisig โ€” two signers from different vendors (e.g. Coldcard + Jade), 3rd key stored elsewhere. One compromised vendor cannot spend, any 2 of 3 recovers. 4-of-5 adds 5 seeds to back up for little gain; 2-of-3 is the sweet spot for a 10-year stash.
