The Goerli Ethereum testnet, a popular platform for developers to test smart contracts and decentralized applications without risking real funds, has been deprecated since January 2023. However, support for the testnet will continue throughout the year. Despite its deprecation, developers can still obtain free Goerli testnet ETH through faucets like Alchemy and QuickNode, which require users to hold a small amount of mainnet ETH to prevent spam attacks. It is important to note that testnet coins hold no economic value and should only be used for testing purposes. For a more up-to-date Ethereum testnet, developers are encouraged to use the Sepolia testnet instead.
