A simple script demonstrating how to atomically exchange Cashu payments for Nostr event signatures using Schnorr adaptor signatures.

This project implements a cryptographic scheme using Schnorr signatures that enables Cashu payments conditioned on the signing of specific Nostr events. Using adaptor signatures, it allows a Payer to make a Cashu payment that can only be unlocked when the recipient provides a valid signature over a specific Nostr event ID.
