No known hardfork for execution on historical block

[MarcBickel]

Version of Hardhat

2.22.3

What happened?

Forked arbitrum sepolia with npx hardhat node, when trying to run a typescript script that calls any function on-chain (even simple view function), I get the error
ProviderError: No known hardfork for execution on historical block 42324641 (relative to fork block number 42324641). The node was not configured with a hardfork activation history.

The block number is the block at which the chain has been forked I believe (didn't specify so should be latest).

Minimal reproduction steps

Fork arbitrum sepolia with npx hardhat node with an alchemy endpoint.

I also encountered it, it should be a problem with v2.22.3, I downgraded the version to v2.22.2 and it ran normally.

[MarcBickel]

I still get it with v2.22.2, forking the same network as above.

I still get it with v2.22.2, forking the same network as above.

Sorry I saw it wrong, I reverted to v2.19.4

[MarcBickel]

Can confirm this error goes away with v2.19.4, but I am relying on features introduced later (and get other errors), so can't really use that version. Thanks for the input though!

[MarcBickel]

As additional input: my script works with anvil running the local fork, so error should be on the node task side

[6xiaowu9]

You can try to roll back to the previous version from v2.22.3

Hi, I can't reproduce this. I'm forking sepolia and running a call with some random ERC-20:

const blockNumber = await ethers.provider.getBlockNumber()
const mockDai = await ethers.getContractAt(["function totalSupply() public view returns(uint256)"], "0xd6a17186e7bde277ad70e5d5c99d042acf30990c")
console.log(await mockDai.totalSupply())
console.log(await mockDai.totalSupply({blockTag: blockNumber - 10}))

Could someone give us a minimal reproducible example?

[MarcBickel]

Steps to reproduce:

1. Have a hardhat config file

defaultNetwork: "arbitrumSepolia",
  solidity: {
    version: "0.8.25",
    settings: {
      viaIR: true,
      optimizer: {
        enabled: true,
        runs: 10,
        details: {
          yulDetails: {
            optimizerSteps: "u",
          },
        },
      },
      evmVersion: "cancun",
    },
  }
networks: {
    hardhat: {
      forking: {
        enabled: true,
        url: `https://arb-sepolia.g.alchemy.com/v2/<APIKEY>`,
      },
    }

2. Run npx hardhat node --fork https://arb-sepolia.g.alchemy.com/v2/<APIKEY>
3. Run npx hardhat run --network localhost scripts/testMultiContract.ts (or any script).
   The first lines of the script are (after getting the accounts) as follows. Most likely hangs with any eth_call though.

const currencyContract = "0xB28bbA1a16eB2aB0B0E4396f90BFbC04B6e344dC";
  const USDT = await ethers.getContractAt("TestnetERC20", currencyContract);
  const currencyDecimals = Number(await USDT.decimals());

4. Get an error

ProviderError: No known hardfork for execution on historical block 44273914 (relative to fork block number 44273914). The node was not configured with a hardfork activation history.

I downgraded the version to v2.20.1 and it worked on optimistic network

"devDependencies": {
    "@nomicfoundation/hardhat-toolbox": "^4.0.0",
    "hardhat": "^2.20.1"
  }

Testcase code :

import hre from "hardhat";
//USDC 合约地址
const USDC_ADDRESS = "0x0b2c639c533813f4aa9d7837caf62653d097ff85";
//USDC ABI 
const USDC_ABI = ["function totalSupply() public view returns (uint)"];

describe("Optimistic USDC", function () {
  describe("Balance", function () {
    it("Get usdc balance by address", async function () {
      const usdcToken = await hre.ethers.getContractAt(USDC_ABI, USDC_ADDRESS);
      const block = await hre.ethers.provider.getBlockNumber();
      console.log("Optimistic Block Number", block);
      //获取 USDT 总发行量
      const totalSupply = await usdcToken.totalSupply();
      console.log("Optimistic USDC totalSupply", hre.ethers.formatUnits(totalSupply, 6));
    });
  });
});

Run command:

fork:
npx hardhat node --fork https://opt-mainnet.g.alchemy.com/v2/...
run:
npx hardhat test --network localhost

Result:

  Optimistic USDC
    Balance
Optimistic Block Number 120288014
Optimistic USDC totalSupply 169377140.604314
      ✔ Get usdc balance by address (3721ms)

@noodlespan I can confirm this fixes the error as well with v2.20.1. I get strange other errors in my script afterwards, but that's most likely on me (reverts for unkown reason, works with anvil). Most likely bug in the rust rework then

[MarcBickel]

@fvictorio Is that enough or do you need more info?

[fvictorio]

Confirmed and important, thanks!

[fvictorio]

I hope we can fix this soon, but in the meantime: a workaround seems to be to immediately mine a block after starting the node. For example, adding this at the beginning of the script:

import * as helpers from "@nomicfoundation/hardhat-network-helpers";

await helpers.mine()
// rest of the script

[MarcBickel]

@fvictorio Thanks for the workaround, can confirm this does fix the problem, at least temporally 👍
(I put the await helpers.mine() in main() if someone else also needs the workaround)
