Decentralized exchanges (DEXs) are revolutionizing crypto trading by eliminating middlemen and putting control back in users’ hands. By 2025, the DEX market is projected to hit $1.2 trillion in volume, fueled by advances in cross-chain swaps, AI-driven liquidity, and regulatory resilience. But with hundreds of platforms vying for attention, how do you pick the safest and most efficient DEX? This guide compares the top 7 decentralized exchanges for 2025, their unique features, and how to trade securely.
