Metamask: ERC20 token deployed to Ganache Network, not showing
As a developer building complex applications using Ethereum smart contracts, it is important 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 Ganache Network to Metamask, showcasing the benefits of using both platforms.
Step 1: Connect Ganache Network to Truffle Project
Start by connecting your project to Ganache Network by adding it to your Truffle configuration file. Here is 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, // Enable one account in Ganache
},
},
}
Step 2: Add Ganache Network to Metamask
Next, add the Ganache network to your Metamask configuration file. This will allow you to deploy Ganache network contracts directly in 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 in Metamask. To do this, follow these steps:
- Clone the 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 the Ganache network to Metamask.
Step 4: Check Truffle Token Balance
Once you have deployed the contract, you can check its balance in Truffle by running the following command:
truffle call ContractName@deployedBalance
Replace « ContractName » with the name of the deployed ERC20 contract and « deployedBalance » with the actual balance value.
Benefits of Using Both Platforms
Using the Ganache network and Metamask offers several benefits:
- Local Development
: Deploying contracts directly in Truffle allows for seamless local development and testing.
- Real-time Updates: Ganache’s WebSocket connection provides real-time updates, allowing you to monitor the performance of the contract and make changes 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 the Ganache network and Metamask, you can create more efficient and effective development workflows for building complex Ethereum smart contracts.
