Blockchain Development Programming Tutorials, Guides & Best Practices

• 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.

In some cases, you might want to use both Etherscan and Infura. For example, you might use Etherscan to query transaction histories or token transfers, and Infura to send transactions or deploy contracts.
