It would be great if your NSEc derived a Border Wallet. From the Border Wallet, pick one 11-word seed and one for the checksum. That child PK would make a public paynyms/silentpay address.
Rotate your keys as you wish.
Shakespeare on-chain wallet experiment: https://nostr-to-bitcoin.shakespeare.wtf/
Your Nostr identity is your Bitcoin wallet. You can send Bitcoin to any npub. No setup is required by either party. It "just works"
Discussion
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.
