Uniswap extended its dominance in decentralized exchange volume, processing $70.6 billion in trades over the latest 30-day period. UNI token climbed 4.55% to $6.39 on September 13 as the broader crypto market remained relatively flat.
The monthly volume figure represents a 38% increase above Uniswap's $51.1 billion average from January through July. The total exceeded the combined activity of PancakeSwap ($29.8 billion), BisonFi ($8.9 billion), and Meteora ($5.9 billion) during the same period.
Volume Concentration Across Networks
Robinhood Chain supplied approximately $26 billion of Uniswap's monthly volume, marking its largest source of activity. Ethereum followed with roughly $23 billion, while Base, Binance Smart Chain, and Arbitrum provided the remaining share. Since launching in 2018, Uniswap has accumulated approximately $3.7 trillion in total trading volume and $5.1 billion in cumulative fees as of early August.
StablePair Hook Adjusts Stablecoin Trading Fees
Uniswap Labs launched StablePair Hook on September 10 with USDC/USDG and USDC/USDT pools on Ethereum mainnet. The v4 protocol feature adjusts pool fees as prices drift from a reference rate, targeting repeated arbitrage opportunities common in stablecoin markets.
Within a narrow price band, the hook quotes a fixed bid-ask spread. Swaps that push prices farther from parity incur no fee, while corrective swaps enter a Dutch auction beginning at a higher fee that decreases each block. This design routes more value to liquidity providers compared to static-fee structures. According to Uniswap Labs, stablecoin-to-stablecoin swaps reached $43.4 billion during the second quarter, exceeding the next three onchain venues combined. StablePair Hook is upgradeable through Uniswap Governance.
Price Levels and Market Drivers
UNI faces immediate resistance between $6.45 and $6.50 on the daily chart. A close above $6.50 would strengthen recovery momentum, while a drop below $6.10 could expose $5.82, the 38.2% retracement level. The Federal Reserve's rate decision scheduled for September 16 represents the next major macroeconomic event that could influence digital asset risk appetite.
