HumidiFi, the Solana-based Prop AMM DEX, recorded a 24-hour trading volume of $5.57 billion on Sept. 29, according to COINOTAG citing Defillama data, placing it level with Raydium and second only to Meteora.

Unlike conventional automated market makers that permit outside liquidity provision, HumidiFi restricts access to the creator’s internal liquidity, a design that delivers tighter slippage characteristics and enhanced MEV protection for routed trades.

The protocol’s integration into the Jupiter routing stack has translated into material throughput, representing nearly one-third of Jupiter’s Prop AMM activity and reflecting its growing significance within Solana’s DEX routing topology.
