how to estimate gas for Optimisim and Arbitrum Nova?

[Andriy-Kulak]

Hi Team!

Is there a way to generate gas costs for Opitimism & Arbitrum? There is no documentation on which tokens are supported. i tried adding token "OP" for optimism which seems to work but costs seem really low so I am not sure if I should trust them since there is no documentation on which tokens can be passed in.

If OP / Arbitrum is not supported here, is there a way to estimate gas costs of contract deployment and method execution using hardhat?

I'm interested too

Support for optimism has been added in the latest release (2.0). To get gas usage for that network just set the L2 option as below:

gasReporter: {
  L2: "optimism"    
}

Arbitrum support is in the pipeline and being tracked via #181. Closing here as partially complete in favor of #181.
