The eth_getBalance method is an Ronin JSON-RPC method that allows you to retrieve the Ether balance of a specified address.
This method can be used to query the balance of any Ronin address, whether it is a contract or an externally owned account (EOA).
A common use case for this method is to display the current balance of a user's account in a wallet application or a decentralised application (DApp).
