Built on ULTRADE infrastructure
PEX uses a modular architecture that combines real order-book trading, native multi-chain support, and gas-abstracted UX to give traders a seamless on-chain experience, built entirely around performance and security.
System Architecture
Smart Contract Engine (per chain):
All trading logic is deployed natively on supported L1/L2s. This includes order placement, matching, settlements, and fee logic - all on-chain and non-custodial.
Order Book Matching Layer:
An off-chain order book engine enables low-latency matching. Orders are placed via on-chain intents, matched off-chain, and settled on-chain, similar to dYdX v4 and Hyperliquid architecture.
Gas-Abstraction Layer
Traders sign orders off-chain, and PEX minimizes or eliminates their need to pay gas by integrating relayers and transaction batching. Settlement is still on-chain, but the user experience feels gasless, optimized for speed and simplicity.
MEV-Resistant & Slippage-Free Execution
Orders are processed through deterministic, transparent logic. This protects users from front-running and slippage while ensuring fair and predictable trade outcomes.
Native Multi-Chain Deployment
Unlike typical DEXs that operate on a single chain, PEX is deployed across multiple L1s and L2s. Traders can access deep, native liquidity on each chain, with no bridging or asset wrapping required.
