In this tutorial, you learned how to interact with the Ethereum blockchain using the Etherscan API. You successfully queried Ethereum wallet balances, transaction details, and ERC-20 token balances. By using the Etherscan API, you can easily access blockchain data without needing to run your own Ethereum node.
The Etherscan API is a powerful tool for developers who want to build applications that require data about Ethereum addresses, tokens, transactions, and smart contracts.
