When you want to interact with the Diode testnet from within your browser, you can do so on the testnet browser. To make MetaMask recognize this testnet you have to add it to your MetaMask installation through these steps.
If you’re not sure head over to https://metamask.io/ and get metamask from there.
After install metamask let’s there should be a little fox icon in the top right of your browser window. Clicking on that you should see the main metamask interface as show below.
Clicking on the top right circle you should see the MetaMask “My Accounts” page where you can find the ‘Settings’ at the very bottom.
Click on the ‘Settings’ entry and scroll to the very bottom again. There you will fine the ‘Networks’ entry and click that.
Finally at the bottom of the Networks settings there is big blue button called ‘Add Network’ click that and enter the Diode Testnet values there as below:
|New RPC URL||https://testnet.diode.io:8443|
|Block Explorer URL||https://diode.io/testnet/#|
When everything worked out well you should now be able to register a BNS name or deploy your own fleet contract via the testnet explorer.
