@fernandomg could you take a look?

Just want to clarify and maybe have a better UX.

Currently the modal with the 'Error' is being displayed despite if the wallet is not installed or locked. The message is quite generic and may lead to confusion.

I can identify each type of error and display:

• the 'Metamask/Nifty' wallet modal when there's no wallet installed,
• and the 'Error' modal with a message asking the user to unlock his/her wallet.

Both errors are triggered already, but just need to be properly handled.

Any thoughts @akolotov @igorbarinov?

My bid is that we need to handle these two cases in different way.
