[nicosampler]

is it possible to make it conditional?
at this moment, we know which network is the user using. So we can do something like this:
[EWC,Volta].includes(network) ? null : BLOCKNATIVE_KEY.

[dasanra]

In general BLOCKNATIVE_KEY is adding some console errors and we are not really using it.
They usually print a rate limit error and we are not using any functionality that needs a KEY.

I think we should remove it for all networks
