Is this some kind of Contract Gas Racket!?

[innerop]

Suggestion

So I just spent over $70 trying to deploy a very simple contract

It succeeds at first but fails during execution

It feels like a racket to me because when I raise the gasLimit to say 250000 it will use it up 100% for the deploy and leave nothing for the execut BUT if I raise it to say 750000 then once again it will use it all up 100% for the deploy and leave nothing for the execution. So it feels like if I raise it to 2000000 it will also eat it all up during contract deployment and leave no gas for execution.

https://etherscan.io/tx/0x877ba3d2dab77221289d11eb1c78c4b53ba22ecbc01706dfc90f657b287a3d6c

This was my 3rd attempt I tried 50000 then 250000 then 750000 then 250000 again after I simplified the constructor. It should only run the constructor which current just sets owner to msg.sender

How the heck are you even supposed to deploy a contract (to Mainnet) without miners taking up all the gas to deploy regardless of what the gas limit (they always take 100% of it for deploy) and leaving nothing for execution.

So frustrrating.

here is my test contract below:

// SPDX-License-Identifier: UNLICENSED

pragma solidity ^0.8.7;

interface xyzToken {
    function balanceOf(address account) external view returns (uint256);
}

pragma solidity >=0.8.7;

contract doThis {
    
    address public owner;
    mapping(address => bool) internal whitelist;

    xyzTokenV2 public token;

    constructor() {
        owner = msg.sender;
    }

    function init(address _usdc) public {
        token = FiatToken(_token);
    } 

}

I think you may be using the wrong bytecode. The contract being deployed in that tx is massive. And the test contract above should be tiny.

Make sure you are using the correct initicode.

The miners have zero control over how much gas your deployment can take. It is fully deterministic and based on things the miners do not control.

I was getting the bytecode from Remix. I just tried with solcjs and the deployedTransaction.wait() is just hanging (not resolving and no error yet after 5 minutes) EDIT: it failed with only "transaction failed" as far as the error message I can see, but on Etherscan it says the execution/stirage didn't have enough gas.

I put about $50 in gas on the msg.sender address

here is the bytecode (about 7kb) which I'm getting from solcjs

(I put it inside a JS object so I can require it and reference the value separately

Important to note that solcjs produces two files, one for the contract above and one with 0 bytes for the FiatTokenV2 contract referenced in the contract above. I don't know why it does that.

[innerop]

If it's failing to execute with $50 in ETH at the msg.sender/signer address then maybe I should just put in $100 and see? I was afraid it would consume it all and still fail. Is there a way to assess how much a contract would cost to get it up and running before burning real money?

[ricmoo]

Keep in mind that a byte is 2 nibbles, so the above code (when I compiled it) is 3.7kb (not 7kb, it's 7662 nibbles or 3831 bytes; 0x1234 is 4 nibbles, but only 2 bytes). If you enable optimizations it is only 1.9kb, which would save you a lot.

Is there any reason you are using mainnet?

I just simulated deploying your contract (in Remix) and unoptimized it requires 879657 gas to deploy, and optimized it requires 556592 to deploy. So, all your above gas limits are definitely too low, so it is running out of gas.

I just deployed it to Goerli and it cost 483k gas. That was with optimizations turned on.

You can always use estimateGas to approximate how much it will cost. But you should definitely also get used to using testnets, as they will save you from burning a hole in your pocket. ;)

[innerop]

EDIT: sorry just got your reply, so replying by updating this,

[ricmoo]

The gasLimit is not measured in ether. It is measured in gas. They are not interchangeable.

gasLimit = units of gas
gasPrice = cost per gas
fee = gasLimit * gasPrice = ether

There is no hard-coded value used as the default gasLimit, it uses estimateGas which simulates deployment on an Ethereum node and uses that.

I was able to deploy your contract just fine. See the link to the transaction in the previous post.

[innerop]

@ricmoo Godd to know about the nibbles vs bytes. how do I turn optimization on with solcjs?

I just did the calculation on gas to dollars and looks like I have to put in $150 to be safe.... but how do I turn on optimization in solcjs?

[ricmoo]

There is a checkbox (in advanced options) to enable the optimizer. I just used the default of 200 runs. If you use the solcjs library, there is a field in the standard input JSON. You will have to check out the Solidity docs for that though.

[innerop]

I see. Thank you so much.

[innerop]

<<Is there any reason you are using mainnet?>>

Yes, I can only get USDC by purchasing it from Coinbase et al and transferring to Mainnet. I have not been able to find a USDC faucet on any of the test nets. I suppose I could deploy the USDC contract myself and become its owner at that address and create a free source of tokens that way, but I didn't think of it till now. 8)

[innerop]

@ricmoo that ended up being around $28 for the one I had written and $5 for the USDC contract method I am calling from the contract I deployed. I am not sure why that one contract deployment created these two different transactions:

1. https://etherscan.io/tx/0x7ca544b66f828abf99578190e5595325a153762dc1d86215d3bfe90347ff6fb5
2. https://etherscan.io/tx/0x8d841d60ff6315a4993dbfc30906245619d99402ae4162fbaaaf8eeee198d4eb

do you have any idea?

Also, any way I can buy you a beer? :) you saved me so much trouble to realize I had to turn on optimization !

Lol! Hit me up if you’re at ETHDenver or ETHTokyo. ;)

I look forward to meeting you in person! but it'll have to wait till next year (health concerns)

In other mews, believe I found an issue in waitForTransaction adding an additional entry to the logs for each tx, with data = "0x" (no data) thus effectively doubling the number of entries in the logs. Will file a bug. :)
