Architecture

Technical overview of VeilSwap's privacy-preserving infrastructure

System Overview

VeilSwap is built on a privacy-first architecture that ensures no personally identifiable information is ever stored or transmitted. Our system comprises three main layers: the Privacy Layer, the Exchange Layer, and the Settlement Layer.

Privacy Layer

The Privacy Layer is the cornerstone of VeilSwap. Every request passes through our Zero-Knowledge Gateway which ensures complete anonymity.

IP Anonymization

All incoming requests are routed through multiple proxy layers. Your real IP address never reaches our exchange engine or any third-party service.

Request Sanitization

Browser fingerprints, device information, and other metadata are stripped from requests before processing. We only retain the minimum data required to execute your swap.

Session Isolation

Each swap operates in a completely isolated context. There's no way to link multiple swaps to the same user.

Ephemeral Storage

Swap data is stored only in encrypted memory during execution. Once completed, all data is cryptographically shredded and cannot be recovered.

Exchange Layer

The Exchange Layer handles rate calculation, order routing, and liquidity aggregation while maintaining complete separation from user identity.

Rate Engine

Real-time rate aggregation from multiple liquidity sources with automatic best-rate selection.

Order Router

Intelligent routing that splits orders across providers for optimal execution and minimal slippage.

LP Aggregator

Deep liquidity pools aggregated from DEXes, CEXes, and market makers for competitive rates.

Settlement Layer

The Settlement Layer executes swaps across multiple blockchains with support for native privacy coin protocols.

Privacy Coin Integration

VeilSwap natively supports privacy-focused cryptocurrencies including Monero (XMR), Zcash (ZEC), and Dash. When swapping to these assets, you benefit from their built-in privacy features on top of VeilSwap's anonymity layer.

Direct on-chain settlement for EVM-compatible chains
Cross-chain bridges for non-EVM assets (BTC, XMR, etc.)
Atomic swap protocols where available

Data Flow

Here's exactly what happens when you initiate a swap:

  1. 1User submits swap request (amount, from/to currencies, destination address)
  2. 2Request passes through Privacy Layer — IP stripped, metadata removed
  3. 3Exchange Layer calculates best rate across liquidity providers
  4. 4Unique deposit address generated (one-time use, isolated)
  5. 5User sends crypto to deposit address
  6. 6Settlement Layer executes swap via optimal route
  7. 7Destination crypto sent directly to user's address
  8. 8All temporary data cryptographically deleted

Security Measures

End-to-End Encryption

All communications use TLS 1.3 with perfect forward secrecy.

No Central Database

There's no database of user information to hack or subpoena.

Cold Wallet Storage

Liquidity reserves are held in cold storage with multi-sig protection.

Regular Audits

Smart contracts and infrastructure undergo regular security audits.
