Check out nostr:npub1rxysxnjkhrmqd3ey73dp9n5y5yvyzcs64acc9g0k2epcpwwyya4spvhnp8 for all of his awesome hardware wallets, especially the many applications of the nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n #Jadewallet .

I created a Vault in #Bluewallet w 2 Jadewallets as stateless (QR code only) signing keys, and 1 mnemonic key.

You can also use the Jadewallet as an air gapped key w/ #Nunchuckwallet
