The inheritance plan relies on the Block/Bitkey server to fulfill claims. If we were to go out of business, we'd aim to give 6 months' notice so customers can sweep their bitcoin. After that, they’d need new arrangements to manage inheritance. If you’re using Bitkey and see us go out of business, you could move your funds to another wallet.
If you're concerned about Block going out of business before your beneficiary completes a claim, consider setting up a backup method. You can add their fingerprint to your Bitkey and share a copy of your Emergency Access Kit to ensure they have access to your funds if needed.
