-
Set Up a New Project
In the Infura dashboard, locate and click the "Create New Project" button. This will prompt you to enter some details about your project. Give your project a meaningful name and select the Ethereum network you wish to use. Infura supports various networks, including Ethereum Mainnet, Ropsten, Kovan, and Rinkeby. For development purposes, you might want to choose a test network like Ropsten.
-
Obtain Your API Keys
After creating your project, Infura will provide you with a Project ID and Project Secret. These credentials are necessary for authenticating your requests to Infura’s services. Store these keys securely, as they will be used to configure your Web3 Applications..
-
Install the Web3 Library
To interact with the Ethereum network, you need the Web3 library. If you’re using Node.js for your application, install Web3 using npm (Node Package Manager):
npm install web3
-
Configure Web3 to Use Infura
In your application code, you need to set up Web3 to connect to Infura using your Project ID. Here’s how you can do it:
const Web3 = require('web3'); const infuraUrl = 'https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID'; const web3 = new Web3(new Web3.providers.HttpProvider(infuraUrl));
Replace YOUR_INFURA_PROJECT_ID with the Project ID you received from Infura. This URL will connect your application to the Ethereum Mainnet. For test networks, replace mainnet with the appropriate network name.
-
Interact with the Ethereum Network
With Web3 configured, you can now start interacting with the Ethereum blockchain. For example, you can check the balance of an Ethereum address:
web3.eth.getBalance('0xYourEthereumAddress') .then(balance => console.log('Balance:', web3.utils.fromWei(balance, 'ether'), 'ETH')) .catch(error => console.error('Error:', error));
You can also send transactions, deploy contracts, and call smart contract functions. Web3 provides various methods to interact with the blockchain.
