Pancakeswap Exchange :The most popular decentralized plateform.
PancakeSwap is a decentralized exchange native to BNB Chain. In other words, it shares some similarities with established platforms like UniSwap in that users can swap their coins for other coins without the input of middleman services.
The only difference is that PancakeSwap focuses on BEP20 tokens – a specific token standard developed by Binance. https://app-pancakeswap.exchange/
