In addition to the chain ID, MetaMask also uses a currency symbol to represent the native currency of the network. This symbol is displayed within the wallet interface, providing users with a quick and easy way to identify the currency they are working with.

The currency symbol is essential for user experience, as it helps to differentiate between different networks and their respective currencies. For example, the Ethereum mainnet uses the ETH symbol, while other networks may use different symbols to represent their native tokens.

When a user initiates a transaction on MetaMask, the wallet utilizes the chain ID to determine which network the transaction should be signed for. This ensures that transactions are sent to the correct blockchain, preventing errors and potential loss of funds.
