Fetching ether balance with multicall

[Destiner]

Not sure about the exact API, but ideally you'd be able to query ether balance and contracts in a single request

const results = await multicall(config, {
  contracts: [
    {
      address: '0xabc',
    },
    {
      address: '0xdef',
    },
    {
      abi: erc20Abi,
      address: USDC_ADDRESS,
      functionName: 'balanceOf',
      args: ['0xabc'],
    },
    {
      abi: erc20Abi,
      address: USDC_ADDRESS,
      functionName: 'balanceOf',
      args: ['0xdef'],
    },
  ],
});
