Using A Test Network
Instructions for using on a test network

For Ethereum we support the Kovan network. When connected to Kovan you should see the Grey Ethereum logo.
For Polygon we support the Mumbai network. When connected to Mumbai you should see the Grey Polygon logo.
In order to use either Kovan or Mumbai, you will need to get testnet assets.

Kovan comes with Metamask as a default test network while Mumbai will need to be manually added to be used.
Select Kovan from your Metamask Wallet
If you do not see Kovan as an option, you will need to go to Settings > Advanced and toggle "Show test networks" to ON
