Metamask: Importing ERC20 token on Ganache silently fails

Here is a step-by-step guide and sample code to help you successfully import an ERC20 token on MetaMask using Ganache:

Important: Before proceeding, make sure your contract is deployed to Ganache and that Metamask has been set up correctly. Also, ensure you have the necessary MetaMask wallet settings enabled.

Step 1: Prepare your contract

Deploy your ERC20 contract on Ganache using a tool like Remix or Truffle.

Step 2: Set up MetaMask

Create a new MetaMask wallet and connect to your local Ganache network. You can do this by following these steps:

• Open MetaMask on your browser.

• Click on the three dots in the bottom right corner of the window and select “Connect to MetaMask”.

• Enter your MetaMask seed phrase or password (make sure you have a backup!).

Step 3: Set up Ganache

Create a new Ganache network with a single node.

• Open Ganache and click on the “Add Node” button.

• Choose a location for your node and click “Next”.

• Create a new wallet using Metamask or another compatible wallet (e.g., Infura Wallet).

• Click “Start”.

Step 4: Import ERC20 token into MetaMask

Open Ganache and connect to the network where you deployed your contract.

• Open a new terminal or command prompt.

• Navigate to the directory where your contract is located.

• Use the following command to import the ERC20 token:

ganache-cli --network=mainnet --port=8545 --chain-id=0 --network=metamask --password= --host localhost:8545 --accounts 1 --from 

Replace with your MetaMask password and with the seed phrase or password for your MetaMask wallet.

If everything is set up correctly, you should see a list of accounts connected to Metamask. Search for the ERC20 token name in this list to find it.

Step 5: Verify the token’s balance

Once the token is found in your list, click on it to view its details. You can also use the following command to verify the token’s balance:

ganache-cli --network=mainnet --port=8545 --chain-id=0 --network=metamask --password= --host localhost:8545 --accounts 1 --from  --accounts balance 

Replace with the name of your ERC20 token.

If all is better, you should see the token’s balance displayed in the command output.

Troubleshooting tips

• Make sure your MetaMask wallet is set up correctly and that you have a backup.

• Ensure that Ganache and Metamask are running on the same network (e.g., mainnet or metamask).

• Check the contract deployment settings to ensure that the token’s address is correct.

I hope this helps! If you encounter any issues, feel free to ask for further assistance.
