The information below details how to access the Ethereum test environments and obtain test ETH. The process to access one of the Ethereum test networks (Ropsten, Kovan, Rinkeby, Goerli, etc.) is the same through MetaMask. Use one of the faucet links below to obtain test ETH.
Ethereum Test Environment Access
To access the Ethereum test environments you can use your existing MetaMask wallet. If you do not have a MetaMask wallet you can download it here. To change from the Mainnet to one of the test networks click on the drop down at the top of your MetaMask wallet to select Ropsten, Kovan, Rinkeby or any other network.
That’s it, now your wallet is pointing to the Ethereum test environment. If you attempt to deploy a contract using Remix it will deploy to the environment that you have selected.
Ethereum Test Environment Sites and Faucets
Use the resources below to place test trades, monitor your transactions on the test network, and/or to obtain test ETH from a faucet. Follow the directions on each faucet page to receive test ETH.
To deploy a smart contract or send funds in the Ethereum test environment test ETH is required. Listed below is information on how to obtain test Ether from several faucets. Keep in mind the faucets below do not distribute real ETH. This ETH is only valid for the test network. You will need to input your public address for your account on the test environment and you will be sent test ETH. Some faucets have a 24 hour timer before sending additional ETH.
