In a dramatic shift on the Solana blockchain, dark pool decentralized exchange (DEX) HumidiFi has surged to become the network’s largest trading protocol by volume. On the 20th, the platform recorded a staggering $1.1 billion in 24-hour trading volume, surpassing established giants like Meteora, Raydium, and Pump.fun.
This milestone is part of a meteoric rise. HumidiFi’s weekly volume stands at approximately $9.7 billion, and its 30-day volume has reached $34 billion, outpacing Meteora’s $31 billion and Raydium’s $21 billion over the same period.
The HumidiFi Model and the Secret to Its Rapid Growth
Launched in mid-June 2025, HumidiFi is a dark pool DEX that employs a proprietary Automated Market Maker (AMM) model, setting it apart from traditional AMMs that rely on public liquidity pools.
As a dark pool protocol, HumidiFi has no public order book interface. Instead of external liquidity providers depositing assets into public pools, trades are executed privately through aggregators like Jupiter. This structure allows traders, particularly those making large orders or managing significant liquidations, to execute trades without revealing their positions or strategies to the broader market.
According to Dune analytics data, since its launch, about 1 million unique traders have executed over 41 million transactions on the platform.
Privacy as a Prevailing Market Trend
HumidiFi’s rapid ascent signals a notable market shift within DeFi, where execution efficiency and privacy are becoming prioritized over the total transparency of public liquidity pools.
The protocol’s success is largely attributed to its ability to offer narrower spreads and reduced slippage, especially for large trades. This effectively solves a key challenge faced by traditional DEXs and is proving highly attractive to institutional investors and professional traders who wish to keep their strategies confidential. Solana’s high-speed, low-cost infrastructure is the ideal foundation for such a demanding trading environment.
HumidiFi’s efficient model has triggered a significant liquidity migration from traditional public platforms like Raydium and Orca toward its more private trading environment.
Despite its explosive growth, the HumidiFi operation remains fully anonymous, with the development team’s identity still unknown. However, its official X account has hinted at a forthcoming reveal, suggesting that increased transparency may be on the horizon as the platform matures, a move likely aimed at building further trust and expanding its user base.
