I will upgrade pancakeswap from version1 to version2 in 1 day.
PancakeSwap is a decentralized exchange for swapping BEP20 tokens on Binance Smart Chain. PancakeSwap uses an automated market maker (AMM) model where users trade against a liquidity pool. Such pools are filled with users’ funds. They deposit them into the pool, receiving liquidity provider (or LP) tokens in return. They can use those tokens to reclaim their share, plus a portion of the trading fees.
