First, from a product point of view, Double complements Uniswap protocol and significantly enhances the capabilities for the liquidity provider (LP) side of the Uniswap product ecosystem. 

Second, Arbitrum token projects are dying for liquidity on Uniswap. Double solves the liquidity challenges for these token projects, which are key community members and growth drivers for both Arbitrum and Uniswap ecosystems. As a result, more Arbitrum token projects will list their tokens on Uniswap and increase the liquidity for their token LP pools on Uniswap.

Double makes AMM LPing profitable, which impacts hundreds of thousands of Uniswap LPs that want to earn high yield from Uniswap. By doing so, more LPs will want to use Uniswap to earn high yields and to deploy massive capital into Uniswap in the Arbitrum ecosystem.
