The Rise of Dark Pools on Solana

  • Dark pools like HumidiFi use proprietary automated market makers (prop AMMs) to quote prices privately and route trades through aggregators, reducing slippage.
  • This attracts large traders who want privacy and cost-efficient swaps, sometimes achieving negative spreads.
  • HumidiFi, despite lacking public front-end hype, draws significant flow from professional market participants due to deep liquidity and private routing.

Competition Remains Fierce

  • Raydium remains a leader with robust liquidity and community incentives.
  • Meteora holds strong market share through integrations and partnerships.
  • PumpSwap caters to retail traders looking for quick Solana meme coin opportunities.

The broader decentralized space is growing, with decentralized-to-centralized exchange trading volumes holding an 18.5% share. On Solana, weekly decentralized trading increased by 6%, reaching $2.7 billion as of September 29.
