Etherscan vs Infura: Choosing the Right API for Your Blockchain Application
- Data Analytics: Use Etherscan if you need to fetch historical data, such as transaction histories, token balances, or account balances.
- Blockchain Explorers: Ideal for building tools similar to Etherscan itself, where you query and display blockchain data to users.
- Read-Only Data: You can’t send transactions, but you can retrieve information about any Ethereum address, smart contract, or token transfer.
- Decentralized Applications (dApps): If you’re building an application that needs to interact with Ethereum in real-time, such as sending transactions or calling smart contract functions.
- Wallets: If you are developing a wallet application that needs to sign and broadcast transactions.
- Smart Contract Deployment: Use Infura to deploy or interact with smart contracts on the Ethereum blockchain.
