Oddbean new post about login | logout What about making static invoices for cashu mints where people can redeem the same QR code for a set of payments connected to an inventory of products. So a cashu token pays out a small amount of satoshis for each product sold but uses the same pay string address? Is this possible? A non custodial static invoice for AMP on lightning still does not exist. This seems like it could be a feature for Phoenix server launching soon, But what about cashu?

I think what I am imagining would be a feature of locktime. A set amount of payments would be associated with the cost of a good, So the mint can pay to pubkeys associated with customer wallets. I think this demands additional features in the e cash codebase. A P2PK with a fixed value associated with an inventory, Where the cashu nut does not expire until the transactions are all fulfilled and the token can expire.
Sorry the customer pubkeys can pay to an owner pubkey to fufill a token.
Each product can have a pubkey and you receive it as a nuts11 token can be filtered by each product.
Huh.
I am imagining being at a Bitcoin event with products to sell, And having an invoice that accepts payment for items. Each product could be a single token, And when this scales out, A business with tokens that have year or multiple year lifespans.
