Blockchain Development Programming Tutorials, Guides & Best Practices

• Rate Limits: Infura’s free tier provides a generous number of requests (e.g., 100,000 requests per day) and supports more requests as you scale. This makes it more suitable for real-time dApps.
• Pricing: Infura’s paid plans offer higher limits and additional features like access to Layer 2 networks.

• Use Etherscan if:
• You only need to read blockchain data.
• You want to build tools for analytics or explorers.
• You don’t need to send transactions or interact directly with smart contracts.
• Use Infura if:
• You need to interact with the Ethereum blockchain in real-time.
• You’re building dApps, wallets, or tools that require transactions.
• You need to write data to the blockchain, such as sending Ether or deploying contracts.

To follow along with this tutorial, you’ll need:

• Node.js installed on your machine.
• A basic understanding of JavaScript and blockchain concepts.
• An Ethereum wallet with some test ETH (using testnets like Goerli or Ropsten is recommended for testing).
• An Infura Project ID to access the Ethereum network.

Next, deploy the contract to the local blockchain (Ganache):
