The Pancakeswap clone is a pre-made solution that allows the user to launch their own DeFi-based Decentralized Exchange (DEX) platform. This DEX platform allows one to trade or exchange cryptocurrencies in a decentralized way, where no central authority or intermediary is involved in the exchange process. One can also build their DEX platform from scratch, but many opt for this clone script as they are cost-effective, time-saving, and offers customization options.
