Mango Markets is a decentralized derivatives exchange and money market built on Solana, operated by the Blockworks Foundation. Mango v4 introduces unified margin accounts that combine spot trading, perpetual futures, and borrow/lend in a single risk engine, settled by the on-chain Mango v4 program. Beyond the on-chain program and the TypeScript client, the project exposes low-latency public market-data feeds through the mango-feeds geyser services - the Fills Feed (service-mango-fills, fills.mngo.cloud) and the Orderbook Feed (service-mango-orderbook, orderbook.mngo.cloud) - which stream fill events and L2/L3 orderbook state for Mango V4 Perp markets and Openbook spot markets over WebSocket.
