Play with Testnet
Try several operations on your own with test assets
Testnets are alternative blockchain networks (replicas) used for testing purposes. Popular Ethereum testnets are, Kovan, Goerli, Sepolia, Linea and you can find all of them at your Metamask.
In order to play around and start exploring some common actions, we’ll need some test crypto to fund our Metamask account. In order to get these test tokens, we’ll use some of the faucet solutions. Note that these test tokens don’t have any actual value and can’t be transferred to the mainnet.
