# Private Escrow Messaging

ZK-Escrow Messaging is Vizor’s private, built-in chat system that lets buyers and sellers communicate directly during a trade — fully encrypted and handled on-chain. No external apps, no exposed messages, and no central moderators.

***

### What Makes It Different

####  1. End-to-End Encrypted Chat

Messages are encrypted and stored securely during the trade. Only the two parties involved can read them. No third-party access — not even Vizor.

####  2. Zero-Knowledge Proof of Delivery

If needed, the system can **prove a message was sent or received**, without revealing what it said. This protects your privacy, but gives you evidence in case of a dispute.

####  3. Temporary by Design

Once the trade is completed or cancelled, all messages are deleted automatically. Nothing is stored long-term. No clutter, no history, no leaks.

***

### Why It’s Useful

* **Avoid misunderstandings**: Ask questions, confirm details, or request proof — directly inside the trade.
* **Dispute protection**: If something goes wrong, you can prove your side of the story without screenshots.
* **Stay secure**: No need to move to Telegram or Discord just to talk — everything happens inside Vizor.

### Use Case Example

You’re buying tokens OTC. You ask:

> “Just sent payment. Can you confirm?”

The seller replies:

> “Received. Sending tokens now.”

If a dispute comes up, both parties can cryptographically prove these messages were exchanged — without ever revealing what was actually said.
