Paxos-issued stablecoin USDG has generated $21.8 billion in decentralized exchange volume so far in September, with nearly all of that activity flowing through Uniswap. The month-to-date figure represents more than half of USDG’s $40.6 billion in cumulative DEX trading volume recorded up to September 21, highlighting a sharp acceleration in on-chain turnover during the current month.
According to the USDG data available through Token Terminal, Uniswap V3 and V4 accounted for approximately 98% of September’s DEX volume. That implies roughly $21.4 billion of the reported $21.8 billion flowed through the two Uniswap versions, leaving only a small fraction distributed among other decentralized venues. Token Terminal identifies USDG as a dollar-pegged stablecoin issued by Paxos and operating natively across several blockchain networks.
Uniswap Dominates USDG Trading in September
The scale of the current month stands out against USDG’s historical activity. With $21.8 billion representing approximately 53.7% of its $40.6 billion lifetime DEX volume, more than half of all recorded USDG decentralized trading had occurred during the first three weeks of September alone as of the Token Terminal snapshot. That comparison measures gross trading activity, however, rather than net capital entering USDG.
The concentration on Uniswap is similarly striking. V3 and V4 are separate protocol versions with different liquidity architecture, but both belong to the same Uniswap ecosystem. Routing 98% of September activity through those two versions makes Uniswap the dominant execution layer for USDG during the measured period, although it does not establish that the same market share will persist as liquidity conditions and incentives change.
High stablecoin turnover can also occur without equivalent growth in supply. The same units can change hands repeatedly through liquidity pools, arbitrage routes and other trading strategies, causing cumulative DEX volume to substantially exceed the amount of stablecoins outstanding. The $21.8 billion figure therefore measures executed swap volume, not $21.8 billion of new USDG issuance, deposits or unique user demand.
Volume Concentration Remains a Snapshot
The routing pattern provides useful information about where USDG liquidity is currently clearing, but it does not reveal who generated the trades or why. Concentrated volume can reflect liquidity depth, routing efficiency, incentives or specific pool configurations rather than a permanent preference for one DEX. It also does not establish how many independent traders participated or how much net capital was committed during the period.
That distinction matters because September is not yet complete. Token Terminal’s September 21 update explicitly said volume had “already” reached $21.8 billion, meaning subsequent trading can change both the monthly total and Uniswap’s 98% share. The next meaningful milestone will be the finalized September volume and whether Uniswap maintains a similarly dominant share once the full-month dataset is available. Longer-term liquidity, repeat volume and distribution across competing venues will provide stronger evidence of whether the current concentration represents a durable USDG market structure.
