I see verified contacts as the most important feature to develop right now. It may not seem revolutionary on its own, but I believe it is a fundamental building block for a resilient P2P network.

- You verify your contact’s identity (npub) in your hardware wallet.

— This is best done offline. You don’t need many contacts, just ones you fully trust.

- When sending an on-chain transaction, you use an address signed by that contact.

— This means you don’t need to check the address on your HWW, just the human-readable name tag.

- The verified contact’s address can be automatically retrieved in the background.

— We tested this using Nostr in our prototype, and it worked well.

- The same approach can be used to verify anything else.

— For example, LN invoices or Ark addresses.

- This could also enable:

— P2P marketplaces

— Social backup

— Trust-based scaling nostr:note174qkw0ujwx3z8867sceg8fd7h9kf0w7j8te6a4a6qd76sap0gksqf7d5y4

Ideally, a high-quality standard would emerge that various HWWs could adopt. This would allow deriving backups for any hot wallets, and verified contacts could be used consistently across all applications.
