Native ETH balance (eth_getBalance):
exec command="curl -s -X POST https://eth.llamarpc.com -H 'Content-Type: application/json' -d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_getBalance\",\"params\":[\"0xADDRESS\",\"latest\"],\"id\":1}'"
ERC-20 token balance (eth_call with balanceOf):
exec command="curl -s -X POST https://eth.llamarpc.com -H 'Content-Type: application/json' -d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_call\",\"params\":[{\"to\":\"0xTOKEN_CONTRACT\",\"data\":\"0x70a08231000000000000000000000000WALLET_NO_0x\"},\"latest\"],\"id\":1}'"
