# Technology Overview

### Singularity’s Darkswap – Technical FAQ

### **1. How does private execution work in Darkswap?**

Darkswap submits orders through Singularity’s zero-knowledge execution layer.\
Users generate encrypted intents locally, and the settlement contract verifies validity via zk-proofs — ensuring trades execute correctly without exposing asset, size, or direction.

### **2. How does the matching engine operate without revealing order details?**

Obfuscated orders are sent to the matching coordinator.\
The matcher pairs compatible orders and produces proofs attesting that:

* Price conditions were respected
* Balances were sufficient
* Counterparty matching was valid\
  These proofs are then verified on-chain before settlement occurs.

### **3. How does non-custodial settlement work if trade data is private?**

The settlement contract sees only:

* Validity proof
* Token movement outcome\
  It never sees the input order metadata.\
  This achieves **auditable settlement** while preserving **transaction confidentiality**.

### **4. How are market makers integrated into Darkswap without leaking inventory signals?**

Market makers run a **local Maker API server**:

* They stream bulk orders privately
* Manage inventory without exposing order flow
* Receive fills through encrypted channels, then settlement happens on-chain via proofs

A GUI version is planned to support professional trading workflows without needing local infra.

### **5. How does Darkswap prevent MEV and order leakage?**

Orders never enter the public mempool.\
Because no asset/size/side metadata leaks, searchers cannot detect or frontrun execution — removing sandwiching, liquidity probing, and footprint tracking.

### **6. How can trades be verified if nobody sees the orderbook?**

Verifiability moves from inspection to **provability**:

* The matching engine generates proofs
* Settlement verifies them\
  This replaces transparent mempool visibility with cryptographic correctness guarantees.

### **7. How will matching decentralize in the roadmap?**

Darkswap moves toward a **P2P matching network** where:

* No node sees the full orderbook
* Peers hold partial encrypted state
* Matching is coordinated through zk-validated interactions

This eliminates reliance on a central coordinator while preserving privacy.

### **8. What happens when assets exit the darkpool?**

Withdrawals send tokens back to a public address.\
Balances are visible again, but **trade history remains unrecoverable** — observers cannot see how deposits evolved into outputs.
