Project Serum is a fully functional decentralized derivatives exchange with trustless cross-chain trading, all at the speed and price that customers want. It's a fast DEX; it has cross-chain support, stablecoins, wrapped coins, orderbooks, and futures; and while having all of those, it's fully decentralized. There are no oracles to centralized price feeds; no tribunals whose honesty you rely on. Serum is pure DeFi. SRM is the utility token of the Serum ecosystem.
