Connecting to Ethereum with Infura and Programmatic Transactions

Connecting applications directly to the Ethereum blockchain can be challenging without running a full node. This text-based course guides you through using Infura as your gateway to Ethereum, enabling you to interact with the blockchain programmatically. By reading and practicing the concepts in this course, you will understand how to set up an Infura project, connect to modern testnets, and sign and send transactions securely using code instead of browser-based wallets. What you'll learn: - Understand the core architecture of Ethereum nodes and how Infura acts as a remote provider - Configure an Infura project to access Ethereum mainnet and modern testnets like Sepolia - Manage private keys securely using environment variables to prevent accidental exposure - Sign and broadcast raw Ethereum transactions programmatically using modern developer libraries - Read blockchain data and monitor transaction status directly through your code You will start by learning the fundamental concepts of web3 providers and node infrastructure. From there, you will walk through setting up your Infura dashboard, writing clean scripts to query blockchain data, and implementing secure transaction signing workflows. This course is designed for beginner blockchain developers and software engineers who want to transition from browser-based dApps to backend blockchain interactions, with no prior Web3 experience required.
