Describe the Problem

Hello,

👁 Context

I am trying to get the return value of a method at a specific block following the next documentation:

  • https://docs.ethers.io/v5/api/providers/types/#providers-BlockTag
  • https://docs.ethers.io/v5/api/providers/provider/#Provider--transaction-methods

💻 System setup

  • OS: Windows 10
  • node: v18.2.0
  • npm 8.9.0
  • ethers: 5.6.9

🔁 Reproduction

// We require the Hardhat Runtime Environment explicitly here. This is optional
// but useful for running the script in a standalone fashion through `node <script>`.
//
// When running the script with `npx hardhat run <script>` you'll find the Hardhat
// Runtime Environment's members available in the global scope.
const { ethers } = require("hardhat");
const hre = require("hardhat");

async function main() {
  console.log(`💻 Network: ${hre.network.name}`);

  // 👁‍🗨 Address we retrieve the data from
  let userAddress = "0xd0a111d4349aad1f8ce82e61d5c8c2beac6b2e92";
  console.log(`👀  Retrieving data from ${userAddress}...`);

  // 👉 Contracts
  const nbuContract = await hre.ethers.getContractAt(
    "NBU",
    "0x5f20559235479F5B6abb40dFC6f55185b74E7b55"
  );

  const gnbuContract = await hre.ethers.getContractAt(
    "GNBU",
    "0xA4d872235dde5694AF92a1d0df20d723E8e9E5fC"
  );

  // 🔨 Get accounts
  let [hacker, _, tester] = await hre.ethers.getSigners();
  hacker = tester;

  // 👁‍🗨 Get data from contract (alt1)
  if (false) {
    let gnbuBalanceAlt1 = await hre.ethers.provider.call(
      await gnbuContract.populateTransaction.balanceOf(userAddress),
      (blockTag = 20260300)
    );
    console.log(`📗 GNBU balance (alt1):\n ${gnbuBalanceAlt1} \n`);
  }

  // 👁‍🗨 Get data from contract (alt2)
  if (false) {
    let gnbuBalanceAlt2 = await gnbuContract.balanceOf(userAddress, {
      // blockTag: 3412629,
      blockTag: 20260300,
    });
    console.log(`📗 GNBU balance (alt2):\n ${gnbuBalanceAlt2} \n`);
  }

  // 👁‍🗨 Get data from contract (alt3)
  if (false) {
    let gnbuBalanceAlt3 = await ethers.provider.getStorageAt(
      gnbuContract.address,
      1,
      (blockTag = 3412629)
    );
    console.log(`📗 GNBU balance (alt3):\n ${gnbuBalanceAlt3} \n`);
    gnbuBalanceAlt3 = ethers.utils.parseBytes32String(gnbuBalanceAlt3);
    console.log(`📗 GNBU balance (alt3):\n ${gnbuBalanceAlt3} \n`);
  }
}

// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

❌ Problem

For the next cases I am getting an error in BSC using a NodeReal archive node (https://meganode.nodereal.io/app/dashboard):

  • blockTag: 3412629
  • blockTag: 20260300
  • blockTag: "earliest"
  • blockTag: -1000

The error response I am getting:

I just tried to reproduce using https://meganode.nodereal.io, seems to work with plain ethers.js. Are you still facing this issue? How are you running the hardhat script and how is the network specified in the hardhat config?

Hello @zemse ,

Thanks for helping. I am using the next code:

const gnbuContract = await hre.ethers.getContractAt(
    "GNBU",
    "0xA4d872235dde5694AF92a1d0df20d723E8e9E5fC"
);

let gnbuBalanceAlt2 = await gnbuContract.balanceOf(userAddress, {
      blockTag: 3412629,
});
console.log(`📗 GNBU balance (alt2):\n ${gnbuBalanceAlt2} \n`);

My hardhat.config.js setup is the next one:

require("@nomiclabs/hardhat-waffle");
require("@nomiclabs/hardhat-etherscan");
const { task } = require("hardhat/config");
require("dotenv").config();

// This is a sample Hardhat task. To learn how to create your own go to
// https://hardhat.org/guides/create-task.html
task("accounts", "Prints the list of accounts", async (taskArgs, hre) => {
  const accounts = await hre.ethers.getSigners();

  for (const account of accounts) {
    console.log(account.address);
  }
});

// You need to export an object to set up your config
// Go to https://hardhat.org/config/ to learn more

/**
 * @type import('hardhat/config').HardhatUserConfig
 */
module.exports = {
  defaultNetwork: "bsc_mainnet",

  mocha: {
    timeout: 120000,
  },

  networks: {
    bsc_mainnet: {
      url:
        "https://bsc-mainnet.nodereal.io/v1/" +
        process.env.ARCHIVE_NODE_API_KEY,
      chainId: 56,
      gasPrice: 20000000000,
      accounts: [process.env.DEPLOYER_PRIVATE_KEY],
    }
  },

  solidity: {
    compilers: [
      {
        version: "0.8.10",
        settings: {
          optimizer: {
            enabled: true,
            runs: 1000,
          },
        },
      },
    ],
  },
};

For executing I am not defining the network so I am taking the default one: npx hardhat run scripts/archiveBalanceOf.js . I want to get the balanceOf at block 3412629 in the BSC, that is, here https://bscscan.com/block/3412629.

Thanks in advance for helping me out.

Best regards, Pedro Reyes.
