Meme Liquid

MemeLiquid is a decentralized perpetual futures trading protocol built on the Solana blockchain that enables leveraged trading on meme coins. The protocol allows users to open long and short positions with up to 10x leverage on tokens such as SOL, LIQUID, and other meme tokens deployed through Pump.fun that have graduated to PumpSwap AMM. MemeLiquid operates through an on-chain risk engine deployed as a Solana program, which handles position management, collateral accounting, and liquidation logic transparently on-chain. Price feeds are sourced from decentralized oracles that track real-time AMM reserves via WebSocket subscriptions to ensure accurate and timely pricing. The protocol features a permissionless token listing system where any project can register their token for perpetual futures trading by paying a listing fee that covers on-chain account rent, initial trading collateral, and a LIQUID token buyback-and-burn mechanism. MemeLiquid uses a slab-based account architecture for capital-efficient storage of user positions and market state on Solana.
