Plebs creating a chain of BTC buys with some rules around each buy having to be bigger than the previous one. Haven’t participated myself.
Haven’t explored this much yet, but I think the idea is:
- Key A signs a message saying “key B is allowed to post as me for X amount of time”
- Key B can be used on behalf of key A until the delegation expires
- Key A never needs to be entered into a website
- When delegation expires, key A can delegate to key C etc.
I think I saw the SeedSigner guys thinking of impelmenting it.
Delegation will solve it soon hopefully

Doesn’t cover nostr specifically yet but gives you an idea how it works.
Doesn’t protect against nostr key being compromised of course.
No, you just derive your nostr privkey from your coldcard seed. So as long as your seed is backed up securely, no need to backup nostr key.
And never enter directly it in a web based client. Use NOS2X extension for example. Or a native app.
Technically you can use BIP85 on COLDCARD now. Just select 32 byte HEX.
