PancakeSwap is a decentralized exchange that runs on the Binance Smart Chain (BSC) blockchain. BSC is a blockchain platform that is compatible with the Ethereum Virtual Machine (EVM), allowing it to support smart contracts and decentralized applications (dApps) similar to those on the Ethereum blockchain.
PancakeSwap uses the BSC blockchain to enable users to buy, sell, and trade digital assets in a decentralized manner, without the need for a central authority or intermediary. It also uses BSC's native BNB token for transactions and fees on the platform.
In short, PancakeSwap does not have its own blockchain, but rather uses the BSC blockchain for its operations.
