Syndr is a decentralized derivatives trading platform built on a Layer 3 rollup (Arbitrum Orbit) that targets institutional-grade traders. It aggregates crypto derivatives—options, perpetuals, and futures—into a single interface, offering a high-performance trading environment with low fees and ample liquidity. The platform works by operating on a secure Layer 3 rollup to process trades efficiently, and it supports portfolio-margining, enabling traders to use their entire portfolio to offset profits and losses to optimize margin requirements. This combination of Layer 3 scalability, institutional-grade infrastructure, and a unified interface differentiates Syndr from other venues by delivering fast, cost-efficient trading with advanced features for sophisticated users. Syndr’s goal is to provide a scalable, low-cost platform that appeals to both institutional and retail traders seeking advanced crypto-derivatives trading and optimized margin management.
