SeedSigner

Jade is good but be sure to flash the firmware before generating a seed (or ideally importing your own rolled seed) and then keep it airgapped after that, since there is no physical security to prevent a supply chain attack and nostr:npub17777777tpz9x2dcvvlw37sgk5gmpffexl0u30gjjgcd59ty92vrs0atnu0 has been able to compromise the Jade by opening, inserting a compromised

chip and closing the device such that you’d never know, and it still works with

Green wallet (Jades companion software wallet).

Wish they’d add better physical security (like making plastic parts break

upon opening) because I like that it’s a more affordable for those who need

such ✌️
