Voting power in governor and token balance on erc20 contract is different

Smart Contracts

I deployed governor contract on Amoy testnet.
Then I am going to call castVote function in governor but although an address has balance in my erc20 token, the voting power was zero.

I checked the token address, timepoint and set the ERC20Votes.
But I can't find reason.
Plz help me if you have experience.
Kind regards,
Peter

Hi Peter,

So I (and others) can better understand could you please post the code for both contracts? FYI - using ``` before and after the code (this helps convert the code to a readable format).

Is your issue:

  1. you have deployed a contract on a testnet (presumably importing a custom token);
  2. you've loaded an address with these tokens; and
  3. you call castVote, however this does not appear to represent a vote cast in the context of the contract?

Let me know if I've misunderstood.

Thank you for your response.

Here is detailed code.

Token contract

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol";

contract MyToken is ERC20, ERC20Votes {
    address public admin;
    address public minter;

    // Address of token holders
    address[] public tokenHolders;

    constructor()
        ERC20("MyToken", "MT")
        ERC20Permit("MyToken")
    {
        admin = msg.sender;
        // _mint(msg.sender, dailyProduction * 360 * 1e19);
    }

Governor contract

import "@openzeppelin/contracts/governance/Governor.sol";
import "@openzeppelin/contracts/governance/extensions/GovernorSettings.sol";
import "@openzeppelin/contracts/governance/extensions/GovernorCountingSimple.sol";
import "@openzeppelin/contracts/governance/extensions/GovernorVotes.sol";
import "@openzeppelin/contracts/governance/extensions/GovernorVotesQuorumFraction.sol";
import "@openzeppelin/contracts/governance/extensions/GovernorTimelockControl.sol";

contract GFEGovernor is
    Governor,
    GovernorSettings,
    GovernorCountingSimple,
    GovernorVotes,
    GovernorVotesQuorumFraction,
    GovernorTimelockControl
{
    // /* 1 day */ /* 1 week */
    constructor(
        IVotes _token,
        TimelockController _timelock
    )
        Governor("MyTokenGovernor")
        GovernorSettings(7200, 50400, 0)
        GovernorVotes(_token)
        GovernorVotesQuorumFraction(4)
        GovernorTimelockControl(_timelock)
    {}
}

I got the voting power of specific address which hold token balance but the voting power was zero.
Here is code for that.

    const currentHeight = await getCurrentBlockHeight();
    console.log("current height: ", currentHeight);

    // get votes
    const accountPower = await GovernorContract.methods.getPastVotes(user2Account.address, currentHeight).call();
    console.log("account power: ", accountPower);

I found issue.
To get voting power, users should call delegate function before start voting.
