Looking up a token on CoinGecko gives me the exchanges where a token is being exchanged at. When I query for Axie-Infinity, in the exchanges table there's a row that says "Binance AXS/USDT". Now the questions comes, what is this swap? Is it the Binance Liquid Swap? If so is this a fork of Uniswap? Furthermore, where can I find the address of the factory?
