- Check the balance of other Ethereum addresses (not just your wallet).
- Send ETH to other addresses.
- Interact with smart contracts using Ethers.js.
In this tutorial, you learned how to use Ethers.js to query the balance of an Ethereum wallet in Node.js. You also saw how to use Infura or connect to a public node to access the Ethereum network. This is the foundation for working with Ethereum and interacting with wallets and smart contracts in a programmatic way.
