Deploying to Sepolia, Goerli, and Other Testnets

This lesson is for enrolled learners

The concept A testnet is a separate blockchain running the same client software and rules as mainnet, but using worthless test ETH, so you can deploy and break things without financial risk. Sepolia is currently Ethereum's primary recommended testnet (Goerli was deprecated by client teams in 2024 as validator demand for test ETH outstripped supply). To deploy anywhere beyond your……
