The Perp DEX leverages a hybrid on-chain/off-chain architecture, decoupling order matching from settlement to reduce gas costs and latency. Orders are matched off-chain but settled on Ethereum, ensuring security while enabling fast execution and low-cost trading$1m on the Line: Synthetix Mainnet Trading Competition^[3].
