OK I did it. Instead of a P2TR address for your npub, I implemented Silent Payments.

I managed to:

  1. Create a Silent Payment address from my npub,
  2. Send a Silent Payment from Cake Wallet (the only wallet I could find that supported it)
  3. Detect the valid transaction outputs that containthe Silent Payment
  4. Swept the funds from the Silent Payment to a fresh bitcoin address that I control using the corresponding nsec (redacted in diagram, below, of course)

So the bottom line, I have shown that any npub can receive silent payments and sweep those funds to another wallet. Total privacy on the public blockchain. No one know I received or sent the funds.

I have the command line working and I will figure how to wire this into the web app in the coming days. That should put an end to the debate of using your social nsec as a wallet.

The command line looks like:

$>openetr sweep-silent-payment NSEC TXID DESTINATION_ADDRESS
