Alternative Faucets

More Faucet services will become available over time. Watch this space!

3. Develop!
Deploy your Contracts

Once you have a Connection and some KETH, you're ready to go!

The Ethereum development ecosystem is ever-growing and you can use many of the same tools that you're already familiar with.


Truffle is the most popular development framework for Ethereum. You can connect to Kovan in one of the following ways:

Use Parity and add the config to truffle.js:
kovan: {
  host: 'localhost',
  port: 8545,
  network_id: '42'
Use a ZeroClient Provider to connect to a remote RPC node such as Infura
