OKX State of DEX 2025 report now live: Solana retail at 48% of DEX volumes, Ethereum preferred for trades of USD50k+

DEXs are rapidly evolving from alternative venues to become a central force in DeFi, driving innovation, accessibility and decentralization. Our report explores the critical challenges of liquidity and market structure, while examining how derivatives, AI integration (Crypto X AI) and the competitive dynamics between Solana and Ethereum are shaping the future of decentralized trading. This analysis aims to help onchain traders and builders navigate opportunities while understanding key technical and operational challenges ahead.

Most notably, we found that Solana-based DEXs, driven by retail trader activity, have surged to command 48% of total DEX volume, while Ethereum maintains its stronghold among whales and institutional traders for large-scale trades exceeding $50,000, revealing a split in how different chains serve distinct trading needs.

• DEXs as the backbone of DeFi, establishing themselves as the cornerstone of the decentralized financial ecosystem through enhanced accessibility, decentralization and technological advancements

• How Solana and Ethereum 2.0 are fighting for dominance in the battle for liquidity, efficiency and scalability in the DEX landscape

• Critical liquidity challenges and innovative solutions, from Raydium's market-making models to Uniswap's evolving design, with a focus on maintaining depth and stability

• The transformative intersection of blockchain and AI (Crypto X AI), where onchain AI agents create new opportunities while raising crucial security and IP considerations

Key findings include:

• Solana is dominating retail DEX volume, while Ethereum has a stranglehold on high-value trades

  • Solana leads in overall DEX volume with 48% market share, with approximately 60% of this volume coming from pump.fun activity

  • Ethereum and its Layer 2s dominate high-value trades, particularly those exceeding $50,000

  • In terms of liquidity pool quality, Ethereum holds 10 of the top 20 spots, followed by Base (5 spots), Arbitrum (2), BSC (2) and Solana (1)

• Asia leads Europe and North America in the developer wars with AI integration a key focus of the industry's builders

  • Builder preferences show Ethereum leading at 20.8%, followed by Solana (11.2%) and Base (10.7%)

  • AI integration dominates builder activity at 33.9%, with focus on Blockchain Infrastructure (20.1%) and DeFi (14.2%)

  • Geographic distribution of developers shows Asia leading at 32%, followed by Europe (31%) and North America (24%)

• DEX derivatives break new ground while familiar TradFi yield instruments enter DeFi

  • While DEX spot volumes still exceed decentralized derivatives by 10x, Hyperliquid and dYdX's appchain innovations signal a path toward CEX-level performance

  • Tokenized T-Bills and basis trading assets (USDe, USR) emerge as yield-bearing base currencies, fundamentally changing the derivatives landscape
