Tell me why my idea sucks so we can make it better:

Fedimint Ded Drp

- Allow a user to send ecash to npub

1. Encrypt using nostimint’s npub and send to nostimint

a. npub of recipient

b. ecash is encrypted with npub of recipient

2. deddrp creates contract (similar to LN gateway)

3. Recipient queries for any outstanding contracts for their npub

4. Receives encrypted ecash after “unlocking” contract

5. decrypt, then use ecash as normal

Was thinking about nostr and fedimint and thought that a whitelist of npubs just creates an account model that is no bueno for privacy. The cryptographic primitives don't have to be nostr either, you could encrypt Step 1.b with any sort of key material. (I think)
