So i took a mnemonic from the ganache. I imported it in the metamask wallet. And now when i am trying to create a custom rpc network where name would be GANACHE and rpc url http://localhost:9545 I am unable to save it. The save button is greyed out. How do i enable that?

You also have to fill the chain id to add a new network. As far as I know, the default Chain ID for Ganache is 1337.

  • It says that This Chain ID is currently used by the Localhost 8545 network. Commented Sep 19, 2021 at 7:25
  • Are you sure that your RPC URL should be http://localhost:9545 and not http://localhost:8545?
