Here’s a step-by-step guide and sample code to help you successfully import an ERC20 token into MetaMask using Ganache:
Important! Before proceeding, make sure that your contract is deployed in Ganache and that the metamask is configured correctly. Also, make sure you have the necessary MetaMask wallet settings enabled.
Step 1. Prepare the contract
Deploy your ERC20 contract to Ganache with a tool like Remix or Truffle.
Step 2. Set Up MetaMask
Create a new MetaMask wallet and connect to the Ganache LAN. You can do this by following these steps:
- Open MetaMask in your browser.
- Click on the three dots in the lower right corner of the window and select “Connect to MetaMask”.
- Enter your MetaMask passphrase or password.
Step 3: Adjust the Ganache
Create a new Ganache network with one node.
- Open Ganache and click the Add Node button.
- Select a location for your node and click Next.
- Create a new wallet using Metamask or another compatible wallet (eg Infura Wallet).
- Click “Start”.
Step 4. Import the ERC20 token into MetaMask
Open Ganache and connect to the network you are deployed to.
- Open a new terminal or command prompt.
- Go 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 configured 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. Check Token Balance
Once a token is found in your list, click on it to view its details. You can also use the following command to check your token balance:
ganache-cli --network=mainnet --port=8545 --chain-id=0 --network=metamask --password= --host localhost:8545 --accounts 1 --from -- ; account balance
Replace with the name of your ERC20 token.
If all is well, you should see the token balance displayed in the command output.
Troubleshooting Tips
- Make sure your MetaMask wallet is configured correctly and that you have a backup.
- Make sure that Ganache and Metamask are running on the same network (eg main network or metamask).
- Check the contract deployment settings to make sure the token address is correct.
Hope this helps! If you have any problems, do not hesitate to ask for additional help.
