HumidiFi is Solana's largest decentralized exchange (DEX) by volume, processing over $1B in daily volume - roughly 35% of all spot DEX activity. Unlike traditional automated market makers (AMMs), HumidiFi is a [proprietary AMM] (prop AMM) that combines on-chain execution with institutional-grade market-making logic. The result: tighter spreads, deeper liquidity, and execution that outperforms both DEX and CEX competitors.
