Multi-vendor multisig. Any vendor may be compromised at any time. The chances that multiple vendors are compromised at the same time is significantly lower.

Agreed, this is a very good option but it can get expensive or tricky to set up if youâre going DIY. Itâs important to think about how those youâll leave your stack to will be able to access it after youâre gone.

One way to reduce cost is to do, say, 2-of-2 where one is your hardware wallet, and the other is software. For example, Sparrow calls these keystores and makes it easy to set up a wallet with a mix of hardware and software keystores. The software seed would be encrypted in the wallet file. This would still be significantly better security than single hardware sig.

Sparrow is the way to go here.

Bitcoin is the worldâs premier value transfer system. Passing keys to heirs is unnecessary. Instead, use long-dated, pre-signed transactions (Deadmanâs Transactions, DMTX) to ensure your heirs can receive coin after you depart.
This requires your heirs to have their own wallets. But this is inescapable. In order to inherit Bitcoin, one must be competent in Bitcoin. Thereâs no substitute for competence.
