If I want to send ecash as payment for freelancing on [SatShoot](https://satshoot.com) I want to do it with p2pk so it is easy to build Reputation from provable zaps, published to nostr but tied to the recipient pubkey.

The problem is when the zap cannot reach the recipient which could be due to multiple causes but I want to have a safe path for clients to get back the p2pk ecash that was never redeemed by the recipient freelancer.
