Paxos' USDG stablecoin generated $21.8 billion in trading volume on Uniswap during September, equal to 98% of its total decentralized exchange activity. The surge follows Uniswap's September 10 launch of a new dynamic fee mechanism for stablecoin pairs, and pushes USDG's monthly turnover to nearly seven times its circulating supply.
USDG, also known as Global Dollar, racked up $21.8 billion in trading volume on Uniswap during September. That figure represents 98% of the stablecoin's total activity on decentralized exchanges. USDG's circulating supply sits at roughly $3.2 billion, so the token turned over nearly seven times its entire supply on a single DEX in a single month.
The StablePair Hook effect
The volume jump traces directly to Uniswap's launch of its StablePair Hook on September 10, a Uniswap v4 feature that introduced dynamic fee structures for stablecoin trading pairs such as USDC/USDG on Ethereum. USDG currently holds over $600 million in total value locked across DEX liquidity pools. That base could help explain how the token absorbed the trading activity without significant price deviation from its dollar peg, the report noted.
From zero to $3.2 billion in under a year
Paxos Digital Singapore launched USDG in November 2024, backed 1:1 by liquid US dollar assets and regulated by Singapore's Monetary Authority. Paxos built the Global Dollar Network, a consortium of partners that share in the economics generated by USDG's reserve assets.
By mid-2026, that network had expanded to over 150 partners, including Robinhood and Kraken. USDG is now live across Ethereum, Solana, Robinhood Chain, X Layer and, most recently, Mantle, where native issuance was introduced to capture additional DeFi trading activity.
What the volume means for stablecoins
Uniswap's total monthly decentralized exchange activity has surpassed $70 billion, meaning USDG pairs accounted for roughly 31% of the platform's entire volume in September. Uniswap v4's hook system lets developers customize pool behavior with modular smart-contract add-ons, and it is turning into a competitive advantage for stablecoins that embrace it early. USDG's volume surge suggests that technical integration with cutting-edge DeFi infrastructure can matter as much as raw market cap.
