Metamask: Metamask not showing balance of custom ERC20 token (hardhat)

Metamask Not Showing Balance of Custom ERC20 Token (Hardhat)

I’m trying to test a custom ERC-20 token using Metamask and Hardhat. After deploying my ERC-20 coin and minting some to one of the HardHat default accounts, I try to add the token to Metamask. However, when I attempt to view or manage my token balance on Metamask, it is not showing any value.

This issue has been plaguing me for a while now, and I’m hoping someone can help me figure out what’s going on. Here are some steps I’ve taken so far:

• Deployed the token: I deployed my custom ERC-20 coin to Hardhat using the solidity contract deployment script.

• Minted tokens: I minted a few thousand tokens to one of the default accounts, which is also being used by Metamask.

• Added to Metamask

  

  : I tried adding these tokens to my Metamask wallet, but it’s not showing up.

Here are some potential issues that could be causing this problem:

• Token balance mismatch: Are you sure that the token has been successfully deployed and minted? Double-check your contract deployment script and ensure that the token is being transferred correctly.

• Metamask account setup: Is your Metamask wallet set up to use the default accounts for testing purposes? Make sure that your MetaMask account is connected to the same Ethereum network as the Hardhat contracts.

• Token configuration

  : Are you using the correct settings for the custom ERC-20 token on your Metamask wallet and in Hardhat? Ensure that your token’s name, symbol, and decimals are set correctly.

To troubleshoot this issue further, I’d like to ask:

• Can you provide more information about your contract deployment script and the tokens being minted?

• Have you tested your Metamask account setup and token configuration on a separate Ethereum network or a different MetaMask wallet?

If you’re still experiencing issues after these steps, please let me know, and I’ll do my best to assist you further.
