Görli Testnet is a testing ethereum netwrok run by Ethereum Foundation for testing the smart-contracts being developed for free.
Goerli uses fake GoerliETH (fake ETH) for transactions.
Faucets
To obtain GoerliETH it's necessary to ask the network for some using faucets.
MetaMask has to be set to Goerli Test Network first (testing networks are not visible by default).
Faucets I've used before:
- Goerli Proof-of-Work faucet (recommended) - requires some mining work in exchange for GoerliETH.
- From my experience, it's the fastest way to obtain GoerliETH for development
- Chainlink - forces you to login with Twitter account
- Goerli Faucet - requires creating an Alchemy account and log in with it
- Faucet Link - other faucets for Goerli and Sepolia
