QuickSwap is a fork of Uniswap, the original Automated Market Maker. Polygon (formerly known as Matic Network) is a sidechain instead of on the Ethereum blockchain. Users can trade with a number of coins and cryptocurrencies at a fraction of the cost and speed, compared to other Ethereum-based DEXs like Unswap. Users are able to earn passive income by providing liquidity to various liquidity pools. Every trade on Polygon costs 0.3% of the amount, a fee is split equally among liquidity providers.
