I'm trying to estimate the gas to call a mint function on some contracts, but most of them require you to pass an eth value or else they will fail. However the wallet I am using contains no eth, so if I try: let mintFee = await contract.estimateGas.mint(1, {"value": ethers.utils.parseEther("1")});, I get: Error: insufficient funds for intrinsic transaction cost. Does anyone know how to call the mint function without having any eth in a wallet?
