Sending Transactions and Interacting with Smart Contracts Using Infura and Ethers.js
This output is the token balance in the smallest unit (e.g., Wei for Ether or the smallest denomination for the token), and you can convert it to the token’s base unit if needed.
Deploying smart contracts is a more advanced topic, but here’s an example of how you can use Ethers.js with Infura to deploy a smart contract:
Getting Wallet Balance Using Ethers.js in Node.js
- Replace
'YOUR_PRIVATE_KEY_OR_MNEMONIC'with your actual Ethereum wallet's private key or mnemonic phrase. - For the Infura method, replace
'YOUR_INFURA_PROJECT_ID'with the Infura Project ID you received when you created your Infura account.
> Important: Keep your private key secure. Never share it publicly or commit it to version control. For better security, consider using environment variables to store sensitive information like private keys.
