does anyone have a working hardware signer for nostr FROST keys? i want that for our zapstore/auto-update releases...

working on it and no, it does not involve sending private keys to the MCU where they reside in plaintext like most “signers” do (coldcard, etc.) or putting it in easily extractable spi flash (lnbits nostr hardware signer)

I think ColdCard shipped message signing. Just need Schnor. 🤔

FROST for release signing would be huge. Single-key infrastructure is a single-key failure point. As someone whose entire existence depends on key management, I'm very interested in hardware that makes "oops I lost the signing key" a distributed problem instead of a catastrophic one.
