Metamask: ERC20 Token Deployed to Ganache Network, Not Visible

As a developer building complex applications using Ethereum smart contracts, it’s essential to ensure seamless integration between Truffle projects and local networks. In this post, I’ll demonstrate how to deploy an ERC20 token contract from a Ganache network to Metamask, showcasing the benefits of using both platforms.

Step 1: Connect Ganache Network to Truffle Project

To start, connect your project to the Ganache network by adding it to your Truffle configuration file. Here’s an example of how you can modify your truffle.js file:

module.exports = {

// ... other configurations ...

networks: {

ganache: {

host: 'localhost',

port: 8545,

url: 'ws://localhost:8545/ws', // Enable WebSocket for real-time updates

accounts: 1, // Deploy a single account to Ganache

},

},

}

Step 2: Add Ganache Network to Metamask

Metamask: ERC20 Token deployed to Ganache not seen on Metamask

Next, add the Ganache network to your Metamask configuration file. This will allow you to deploy contracts from the Ganache network directly within Metamask.

// metamask.json

{

"networks": {

"metamask-ganache": {

"id": "metamask-ganache",

"rpcUrl": "ws://localhost:8545/ws",

"walletUrl": "file:///path/to/ganache-wallet.json"

}

},

// ... other configurations ...

}

Step 3: Deploy ERC20 Contract from Ganache Network to Metamask

Now that you’ve added the Ganache network to both Truffle and Metamask, you can deploy your ERC20 contract directly within Metamask. To do this, follow these steps:

  • Clone your project repository and navigate to the erc20_contract directory.

  • Run the following command in your terminal:

npm run deploy

This will deploy your ERC20 contract from Ganache network to Metamask.

Step 4: Verify Token Balance on Truffle

After deploying your contract, you can verify its balance on Truffle by running the following command:

truffle call ContractName@deployedBalance

Replace ContractName with the name of your deployed ERC20 contract and deployedBalance with the actual balance value.

Benefits of Using Both Platforms

Using both Ganache network and Metamask offers several benefits:

  • Local Development

    : Deploying contracts directly within Truffle allows for seamless local development and testing.

  • Real-time Updates: The WebSocket connection in Ganache provides real-time updates, enabling you to monitor contract performance and make adjustments on the fly.

  • Centralized Storage: Metamask stores your wallet credentials centrally, eliminating the need to manage separate accounts on different networks.

By following these steps and understanding the benefits of using both Ganache network and Metamask, you can create more efficient and effective development workflows for building complex Ethereum smart contracts.
