eth_getBalance on Sonic
Returns the native-token balance (in wei) of an address at a given block. The standard way to read a wallet's balance.
This returns the native coin only — for ERC-20 balances use eth_call against the token's balanceOf. Pass an explicit block number for point-in-time reads; latest moves every block.
