Goerli was the first Ethereum testnet, is cross-client, and features all the mainnet features in a safe environment for development and testing. Developers making Ethereum-destined DApps first deploy to the Goerli testnet for no gas fees to make sure their use cases are well-met before deploying to the mainnet for immutability. However, while you can use the Goerli testnet, we caution against it as the Ethereum Foundation has announced that Goerli will soon be deprecated. Developers are recommend to use the Sepolia testnet and Sepolia faucets.
