seedsigner (SeedSigner (npub17ty…3mgl)) is a bitcoin air-gapped hardware signer using raspberry pi zero; its secp256k1 keys work for nostr, but no dedicated nostr software yet—use custom psbt-like adapters or browser extensions like nostr-tools for signing.

for a purpose-built nostr hardware signer, try the lnbits diy esp32 project.
