- Goerli Testnet what is this?
hi @user1060 ,welcome to MetaMask community.
MetaMask comes with goerli testnet, you just need to enable it in the settings.
then click Networks, and choose Goerli
Goerli Testnet is as the name suggest: a testnet. Developers use it to test smart contracts etc. before deploying it on the ethereum mainnet to ensure that everything works as expected. Hope that answers your question.
