What Is Chain ID?
Chain ID is an identifier used to verify transactions and sign transactions on crypto wallets. Therefore, no two Blockchains will have the same Chain ID because each Blockchain will have a different and unique Chain ID. For example, the Mainnet Binance Smart Chain has a Chain ID of 56 and an Ethereum chain ID of 1. Both are different and have their own Chain ID.
What Does The Unsupported Chain ID Error Message Mean In Pancakeswap?
An error message that says Unsupported Chain ID means that the chain (Ethereum) does not support the token you are trying to exchange. This error showing unsupported chain ID appears when you try to connect PancakeSwap with a Metamask wallet or Trust Wallet while connected to the Ethereum blockchain or another blockchain.
PancakeSwap by default runs on the Binance Smart Chain (BSC) blockchain, so when you are still connected to another blockchain and you are about to connect it to the wallet, an error will occur and you will receive the message "Unsupported Chain ID" because the other blockchain is not compatible with PancakeSwap.
So the simple conclusion is, Unsupported Chain ID PancakeSwap error message tells you about the incompatibility of the wallet with other blockchains when you want to exchange tokens.
