How to increase gas limit on a transaction?

Moralis General
#1

Is it possible to specify the gas limit that the user allows to use for a specific transaction, when using:

Moralis.executeFunction(options);
#2

it is not possible from what I know to set that gas limit with executeFunction

usually you don’t have to change that limit, as metamask will run gas estimation to set that value

#3

Thanks for the fast answer!
Hmm, ok, because I’m trying to simulate an iteration on a list with more than 10k elements (as if I have 10k users tracked on my contract), but I got this error:

Anything I can do to fix this? I’m using remix.ethereum.org, but I got the same error if I try to call the function with Moralis

#4

that usually means that the transaction will fail with an exception and you have to find out why it will fail

#5

I just tried to do a for cycle with 50k iterations and I increased a counter every time. But yeah, I guess you can’t do huge for loop on a smart contract

#6

You have an issue with your contract. Probably, you are trying to deploy on testnet?

#7

Yeah I’m on testnet. But I don’t think there is anything wrong with my test code. You can take a look if you want:

contract Test {
    
    uint256 public iterations = 0;

    function tryGasException() external{
        
        while(iterations< 50000) {
            
            iterations++;
        }
    }
}

I can only do 12k iterations without getting an error

#8

you can set a different gas limit in metamask before sending the transaction

#9

Thank you, I was just curious to know if it was possible to set it by code, so that the user doesn’t have to change it manually, but apparently I can’t :grin:

#10

I think that you may be able to do that if you use web3 directly and not executeFunction

#11

Try to deploy on mainnet (you don’t have to approve the transaction) and it will go through.

You can avoid gas fees in some ways, including:

  1. Waiting for lower prices

During the weekend hours of 9 p.m. to 1 a.m. PST, when America is getting ready for bed, and Europe is just waking up, gas prices are often at their lowest.

  1. setting a minimum gas fee

Before finalizing a transaction, you can set your gas fee on Metamask Instagram to “Low.”

  1. canceling a transaction

If you change your mind or wish to wait for cheaper gas prices, you can cancel a transaction already in progress.
