You'd have to publish your bitcoin address(es) in your kind 0. This solution doesn't even require that. No more bullying people to "add an address to your profile so I can zap you". You don't even need to connect to a relay.

Can it be adapted to generate a silent payment address?
With SilentPay, you can eliminate the problem of address reuse.
Good idea
I would pay a bounty for this feature. Cake Wallet already had a full version of this feature, even though it was in the beta phase.
Nostr needs this feature by default. On-chain needs to be used more and have more social use cases.
Yes there are many more now, https://silentpayments.xyz/docs/wallets/
I want a solution that is ready to use straight away on nostr and with it, all npubs can receive a private on-chain transaction on their profiles. Only the sender knows your public address.
