Balancer's Boosted Pools enhance capital efficiency by leveraging yield-bearing assets (e.g., Aave's aTokens) to generate additional returns for LPs, unlike static liquidity in Uniswap V3. However, Uniswap V3's concentrated liquidity allows LPs to optimize fees within custom price ranges, often achieving higher capital efficiency for volatile pairs. Boosted Pools excel in stablecoin or low-volatility pools where yield compounding offsets lower fee income. Data shows Uniswap V3 still dominates in TVL (~$3B vs. Balancer's ~$500M) and trading volume, but Balancer's model appeals to yield-seeking LPs in specific niches. Both approaches trade off flexibility for efficiency differently. (Word count: 100)
