@@ -34,8 +34,8 @@ When a sender wants to pay the recipient, the sender initiates a swap-in payment
* The sender generates a 32-byte random element `rand`
* The sender calculates a tweaked pubkey for the recipient: `R' = hash(s*R, rand)*G + R`.
* The sender generates a shared preimage secret for the recipient : `P = hash(rand)*G + R`
* The sender `S` then sends a [NIP-04](https://github.com/nostr-protocol/nips/blob/329cd8d8a19fd1dcb12df7eb7a5d640b2a5b6bf8/04.md) encrypted DM to the recipient containing rand and payment value.
* The recipient `R` can locally construct his tweaked pubkey `R'` and preimage `P` from the rand value, and the sender's npub `S`.

Although it seems similar to keysend due to the sender generating the preimage, the proof of payment here is not the revealed preimage but the on-chain transaction (swap factory) itself.
