So this actually seems to be a Popular Opinion. Let's retire "Bitcoin Hardware Wallet" and adopt "Bitcoin Signing Device" from now on.Let's retire "Bitcoin Hardware Wallet" and adopt "Bitcoin Signing Device" from now on.

Someone posted the other day that their device screen died, so they bought a new one to "move their coins into." The coins were never in the device. They're on-chain, and the seed derives the keys that move them.

A signing device is not long-term storage. It signs. We hope it lasts, but it's the metal backup of the seed that matters.

The work ahead is difficult, but it has to be done. If anything good can come from the Coldcard tragedy, let it be this.

Some feedback on my post and my comments:

➡️ slush and Trezor tried this in 2016 and sales dropped.

I think this is a different time and the industry/users have matured. If there was ever a time to do it, it's now.

➡️ No one knows what a "signing device" is and we're making it harder for people new to BTC to understand.

There are basic things people need to learn to self-custody correctly. Secure cold storage isn't easy. It's not hard, but it's not easy.

➡️ Some devices can generate keys, store them, some are stateless, etc.

Yes, but the lowest common denominator is they all sign.

➡️ Why not call them Key Management Tools, Keychain, Authorization Device, etc?

Keychain isn’t a good description. Your keys could be or could not be in the BSD. Also, Keychain is Apple's built-in credential store for passwords, certificates, and keys, and since iOS 16 it also acts as a passkey provider. "Signing" is perfectly in line with "multisig" terminology.

I'll stop calling them HWWs now and use the Bitcoin Signing Device / BSD term.
