Launched by Tony Kogias in early 2022, the Optimism Goerli Faucet is a free tool that provides developers with ETH and DAI on the Optimism Goerli Testnet. This allows developers to accurately test with dApps and tools in an environment where on-chain transactions will not cost any tangible value. In order to use the faucet, users must connect a one month old Github account. This measure prevents bots from farming testnet assets. Every withdrawal gives the user 0.2 ETH and 100 DAI on the Optimism Goerli Testnet.
