USDC DEX Trading Volume Highlights
USDC, a popular stablecoin, recorded a significant $81.2 billion in decentralized exchange (DEX) trading volume over a 30-day period ending around October 12, 2026. This volume accounted for roughly half of all stablecoin trading on DEX platforms. Uniswap's v3 and v4 deployments handled $26.4 billion of the total, with Uniswap's v4 platform capturing 47.2% of total stablecoin DEX activity, amounting to $76.2 billion. USDC's circulating supply was approximately $74.6 billion at the end of September 2026, with $40.2 billion in weekend DEX trading volume during the third quarter of 2026. The article notes that some DEX volume is inflated by flash loans, and Uniswap's v4 release introduced lower fees and enhanced routing options.
