Metamask: ERC20 token deployed to Ganache network, not visible

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

Step 1: Connect the Ganache network to the Truffle Project

To get started, connect your project to the Ganache network by adding it to your Truffle configuration file. Here is an example of modifying the 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, // Install a single account in Ganache
},
},
}

Step 2: Add the Ganache Network to Metamask

Next, add the Ganache Network to your Metamask configuration file. This will allow you to install 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 the ERC20 contract from the Ganache network to Metamask

Now that you have 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 go to the `erc20_contract’ directory.

• Run the following command in the terminal:

npm run deploy

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

Step 4: Check your token balance on Truffle

Once your contract is deployed, you can check 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

There are several benefits to using the Ganache network and Metamask:

• Local development

  

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

• Real-time updates: Ganache’s WebSocket connection provides real-time updates, allowing you to track contract execution and make changes on the fly.

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

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