Expand original in3 example interacting with contracts but through web3. Extends https://gist.github.com/simon-jentzsch/48fd7a5e9fd59e6d3a0c00815d37d24d

in3-test-web3.js

// import in3-Module
const In3Client = require("in3").default;
const Web3 = require("web3");

// use the In3Client as Http-Provider
const web3 = new Web3(
  new In3Client({
    proof: "standard",
    signatureCount: 1,
    requestCount: 2,
    chainId: "mainnet",
    replaceLatestBlock: 50
  }).createWeb3Provider()
);

const myTokenContract = "0xdac17f958d2ee523a2206206994597c13d831ec7";
const myAccount = "0x5754284f345afc66a98fbb0a0afe71e0f007b949";
const erc20Abi = [
  {
    constant: true,
    inputs: [{ name: "_owner", type: "address" }],
    name: "balanceOf",
    outputs: [{ name: "balance", type: "uint256" }],
    payable: false,
    stateMutability: "view",
    type: "function"
  }
];
const tokenContract = new web3.eth.Contract(erc20Abi, myTokenContract);

tokenContract.methods
  .balanceOf(myAccount)
  .call()
  .then(balance => console.log("balance:", balance), console.error);

This is an interessting error, since this is what happens:

1. incubed is updating its nodelist (which worked)
2. the client is now sending out the eth_call

{"jsonrpc":"2.0","id":1,"method":"eth_call","params":
[{
    "data":"0x70a082310000000000000000000000005754284f345afc66a98fbb0a0afe71e0f007b949",
   "to":"0xdac17f958d2ee523a2206206994597c13d831ec7"
},
"latest"
],"in3":{
  "latestBlock":50,
  "verification":"proofWithSignature",
  "signatures":["0x591761898ba2dfcf3b230bd3ab7d0de0c4ef168f"],
  "version":"2.1.0"
}}

The result looks good, so now we are trying to verify it.

1. Signature and blockheader is correct
2. MerkleProofs for all the contracts and storage-values can also be verified
3. But now we verifiy the result by executing the code in the evm and here I ghet an exception (comming from ethereumjs-vm ) : base fee exceeds gas limit
