how to use hardcoded gasPrice and gasLimit for all transactions

[shunjizhan]

Hi, according to the doc, in hardhat config, gas will override gasLimit, and gasPrice will override gasPrice for every transaction. However, when I set a hardcoded value for the gas params:

networks: {
  myNetwork: {
      gasPrice: 204369036266, 
      gas: 53064000,
  }
}

I saw my contract deployment transaction only used 204369036266 as gasPrice, but didn't use 53064000 as gasLimit, and it queried eth_estimateGas and used the result for gasLimit.

Is this expected? Did I misunderstand what the docs mean?

Basically I am trying to use these hardcoded gas params for every transaction, including contract deployment and call, in truffle if I put the same setting in truffle config it will work, so I was wondering how should I do it with hardhat? Thanks for the help!

Sadly this doesn't work with ethers.js. The docs should be clearer about this fact, sorry about that.

To clarify: this works when sending "low level" transactions, and I think it also works with hardhat-web3, but most people use ethers.js with hardhat-ethers now, so this part of the docs is misleading.

Thanks! And it would be nice to clarify this in the doc so other devs won't get confused for this same issue : )

Oh yes, we have an open PR for that, we just need to get it merged 🙂
