Uniswap V2 vs. V3 Volume over the past 6 months
Since the introduction of V3 in May 2021, Uniswap V2 has seen a slight decline in volume, bar the occasional spike. With the migration of liquidity from V2 to V3, this is to be expected. Uniswap V2 introduced ERC20-ERC20 token pools. V3 introduced Uniswap's concept of concentrated liquidity - 'liquidity that is allocated within a custom price range', amongst other new features. Trading volume was calculated by aggregating the daily USD value of all trades in V2 and V3 over the past 6 months.
