How do I secure my key? It’s easy to secure bitcoin private key with hardware wallet, how about Nostr private key? If I lost it and leak it how do I reset?
Discussion
Coinstr is compatible with hardware wallets.
Nostr Connect may also expand to include hardware or air-gapped signing (QR-code only communications) CC: #[3]
Often key loss can be addressed through the spending policy though. You will have a stash wallet or vault that is 2 of 3 of your own hardware wallets for your big stack. Single sig for your day-to-day, and lightning for shopping and zapping.
If a key becomes compromised, the coins can be swept to a new vault with an updated policy that has the new key. (you technically don't 'reset the key', you 'reset the policy')
A simple 3 of 5 looks like this. If any 1 (or even 2) people lose their key, they notify the others and the policy gets reset and the coins moved to the updated policy.
