Hum.. is it possible to send funds on-chain to a new address that is controlled by a nostr private key?
In other words, can I unilaterally assemble a UTXO that unlocks itself with a simple NIP98 event of the receiver?
🤔

That’s some 2030 shit right there. 🤯
Honestly this is what I'm waiting for.
That would be so awesome
Every nsec is an onchain wallet, when creating a nostr account you could create an xpub for the user, the user could keep it private in a nsec bunker, other user would send an event asking the npub for an address and the bunker would give it. Or the xpub can just be public if the user wants.
No, without the xpub step. My idea was just to use the regular nostr pubkey to send sats to people that are not Bitcoin ready yet.
You could hide all that from the user, users would only know npubs. Otherwise maybe you can have a look at paynyms in bitcoin, don't know the inner workings but maybe it would be possible to use npub instead of a paynym code.
Would be more useful to accumulate Sats for someone not yet on #nostr.
Usecase: someone’s external post gets shared here but they’re not on nostr. They can join and collect those Sats
Yep, that's the goal. Or if they are here, but they just haven't setup their ln address yet.
Here is a solution for this scenario: AcceptLN.com a service to Type any email address — instantly send it using Bitcoin Lightning
#lightning #email #service
When tipping people that are not ready to be tipped by bitcoin I usually shared private keys with them, together with a disclaimer that these funds may get taken by me if they don't use them within 3 months. I printed that on paper wallets and so far I did not take any back but I fancy to believe I keep the backup somewhere in case I need to. I've seen waitresses throw away extra tips in Bitcoin right in front of me and I know that less than 5% did redeem the coins a year after I left them as tips, so by keeping a backup I can mathematically be 20 times more generous with my tips if I collect the lost coins later.
The same will apply to nostr users. They might not be that unlikely to "get" Bitcoin but I'm sure half of them will lose their nsec or not care about bitcoin ever.
You could use Bitcoin Script.
// Main script
OP_OVER OP_HASH160
OP_IF
OP_VERIFY
OP_ELSE
OP_RETURN
OP_ENDIF
//
OP_VERIFY
OP_BOOLAND
//
// Example condition: check if the event content contains a specific string
//
// Example: Unlock the UTXO by sending the funds to a specific address
Yes Supertestnet built a tool similar to what you're requesting I believe
Could modify one of his repos if needed check his github
Nice, can we use something like that to setup addresses, lightning channels or maybe cashu mints where people can receive noncustodial (or self custodial) sats without having to setup their lightning address in their Nostr account?
Disclaimer: I have no idea what I'm talking about.
But my guts tell me that nostr can become THE global payments network.
On chain is for savings. And ecash over nostr is for spending. Npubs could be stores/stalls for small businesses, rather than a twitter like profile it could be a storefront.
Yes for sure. I think there's a way to use his whisper address and lightning box to self-host your own lightning address, serverless, and be able to send/receive at will
The brilliant thing is that its serverless, using only a key which the user would have when setting up their nostr.
It'd be like their first DM
- "Here is your secret phrase for your #zaps. Keep it safe like your nsec!"
Something like that maybe. Maybe even better if thought more deeply upon.
I support anything with default npub bitcoin, whether on-chain, lightning, or ecash!
Not meant to be cold storage but zero setup nostr hot wallet. 🤓
That would be so awesome.
Please work with nostr:npub1mhcr4j594hsrnen594d7700n2t03n8gdx83zhxzculk6sh9nhwlq7uc226 on building this in #amethyst
