All pre-funded address balances drop to 0 after running a transaction

[BarneyChambers]

I am running a forked instance of Arbitrum using ganache like so:

ganache-cli --fork https://arb-mainnet.g.alchemy.com/v2/MYAPIKEY --db ./ganache-data -h 0.0.0.0 --chainId 42161 --mnemonic "my cool mnemonic"

I receive my prefunded wallets each with 100 ETH, but when I run any smart contracts on my forked instance, afterwards all of my ether balances on my funded accounts drop to 0.

Is this intended behavior or a bug?

[davidmurdoch]

There is a bug when starting with an existing --db. It doesn't validate that the start up params given match the ones that created the db in the first place, the mnemonic you are giving it is likely different than the mnemonic that was given when the db was first initialized.

Another perspective of this bug: ganache should re-fund the mnemonic's accounts with 100 eth every time it starts up, but doesn't.

That's probably what is happening here.

Here is the issue: #1030

[BarneyChambers]

Thank you. I have rm -rf ./ganache-data but I am still having the issue. Are there any other config files etc I might need to try deleting to reset my ganache back to default?

[davidmurdoch]

What version of ganache?

[BarneyChambers]

Ganache CLI v6.12.2 (ganache-core: 2.13.2)

[davidmurdoch]

Oh. Uninstall that. It's deprecated. Install ganache via npm install ganache -g

[BarneyChambers]

Thanks, I updated to latest using npm install ganache -g and it seems that I am still having the issue after I delete my db folder, and make a fresh instance of my blockchain, after running a couple of scripts, it seems that my funded balances all go to 0

I am now using ganache v7.9.0 (@ganache/cli: 0.10.0, @ganache/core: 0.10.0)

[davidmurdoch]

Can you paste the ganache output?

Hm, it seems that no transactions are being sent here. Can you provide a reproduction script?

[BarneyChambers]

Sure, if I run these two scripts, afterwards I will lose my ETH in the funded accounts. For reference, I am using hardhat in typescript mode. The way to run these in hardhat is npx hardhat run scripts/theScriptYouWant --network arbitrumFork where arbitrumFork is one of the chains in my hardhat-config.ts that points to my ganache instance:

wrapETH.ts

import { ethers } from "hardhat";
//import "@uniswap/v3-periphery";


const main = async () => {
  const [owner, ...accounts] = await ethers.getSigners();

    console.log("owner address: ", owner.address);
    let WETHAddress = '0x82aF49447D8a07e3bd95BD0d56f35241523fBab1';


    //wrap 50 ETH into WETH
    let WETH = new ethers.Contract(WETHAddress, ['function deposit() public payable'], owner);
    let depositTx = await WETH.deposit({value: ethers.utils.parseEther('50')});
    await depositTx.wait();

    console.log(`Wrapped ETH!`);
};

main()
  .then(() => process.exit(0))
  .catch((error: Error) => {
    console.error(error);
    process.exit(1);
  });

SwapETHForUSDC

import { ethers } from "hardhat";
//import "@uniswap/v3-periphery";
const main = async () => {
  const [owner, ...accounts] = await ethers.getSigners();

    console.log("owner address: ", owner.address);

    //define uniswap v3 router
    let uniswapV3RouterAddress = '0xe592427a0aece92de3edee1f18e0157c05861564';
    let usdcAddress ='0xff970a61a04b1ca14834a43f5de4533ebddb5cc8';
    let WETHAddress = '0x82af49447d8a07e3bd95bd0d56f35241523fbab1';

    let ExactInputSingleParams = {
        tokenIn: WETHAddress,
        tokenOut: usdcAddress,
        fee: 500,
        recipient: owner.address,
        deadline: 1913450590, //2030
        amountIn: ethers.utils.parseEther('50'),
        amountOutMinimum: 65000000000, //65k
        sqrtPriceLimitX96: 0
    }


    console.log('approving...');
    //approve uniswap v3 router to spend WETH
    let WETH = new ethers.Contract(WETHAddress, ['function approve(address spender, uint256 amount) public returns (bool)'], owner);
    let approveTx = await WETH.approve(uniswapV3RouterAddress, ethers.utils.parseEther('50'));
    await approveTx.wait();

    console.log('swapping...');
    let uniswapV3Router = await ethers.getContractAt('ISwapRouter', uniswapV3RouterAddress);
    let swapTx = await uniswapV3Router.exactInputSingle(ExactInputSingleParams);
    await swapTx.wait();
    console.log(`Swapped 50 ETH for USDC!`);
};

main()
  .then(() => process.exit(0))
  .catch((error: Error) => {
    console.error(error);
    process.exit(1);
  });

[davidmurdoch]

I haven't run this yet, but are you sure your hardhat mnemonic matches your ganache mnemonic? And that the accounts they are using are the same (your logged "owner address" should match the first account in ganache's list).

[BarneyChambers]

Yes I am 100% sure they are the same

I have made a video reproducing the issue:
