SushiSwap (SUSHI) is an example of an automated market maker (AMM). An increasingly popular tool among cryptocurrency users, AMMs are decentralized exchanges which use smart contracts to create markets for any given pair of tokens.

SushiSwap launched in September 2020 as a fork of Uniswap, the AMM which has become synonymous with the decentralized finance (DeFi) movement and associated trading boom in DeFi tokens.

SushiSwap aims to diversify the AMM market and also add additional features not previously present on Uniswap, such as increased rewards for network participants via its in-house token, SUSHI.

Uniswap is a decentralized exchange (DEX) which first introduced the automated market maker (AMM) model. Unlike with an order book, traders are provided with constant liquidity thanks to the “constant product” formula. The V2 version was first based on Ethereum, before branching out to other blockchains that support ERC-20 tokens.

While the V1 version of Uniswap only supported swapping ETH-ERC-20 token pairs, the V2 version did away with this bridging problem and introduced flash swaps. These allowed users to swap between different ERC-20 tokens without incurring too much slippage. It also introduced protocol fees, which contributed to the platform's ongoing development. Furthermore, the V2 version began using wrapped Ether over native Ether for its core contracts.

The exchange’s popularity gave birth to a V3 version with concentrated liquidity and more flexible fees, which improved the user experience for traders and liquidity providers alike.()

Baes on these are some key differences between these two DEXs:

In this bounty we were asked to compare the market share(measures such as number of trade or number of swaps, etc.) of Sushiswap and Uniswap on the following L2 chains(Polygon, Arbitrum, Optimism).

For this purpose, I have used ==arbitrum.core.fact_event_logs==, ==optimism.core.fact_event_logs== and ==polygon.core.fact_event_logs== tables to calculate count of pools, swaps and swappers on each DEX.
