Instead of creating a hodl invoice, we can use a regular invoice from a user's configured federation. A lightning gateway for that federation will be running 24/7 to settle the payment instantly and in an atomic way. Our LNURL Address server, called Blinded-Hermes, will create an ecash contract that spends to a pubkey-locked ecash note. We use the user's registered pubkey for this. Once the lightning gateway processes the payment, the federation will complete the contract and provide the user with the new ecash.
As always Mutiny team keeps on knocking it out of the park. Great Job
