Ethereum: contract keeps reverting but gets depoyed when i don’t send a value and does not deploy when i send a value

Ethereum Contract Issues: Reverting But Not Deploying

As an Ethereum developer, you’ve likely encountered issues with smart contract deployment and execution. In this article, we’ll delve into the details of a recent issue that has been affecting users like yourself.

The Problem

We’ve received reports from several users who have been experiencing a peculiar behavior with their Ethereum contracts. The issue involves a contract that keeps reverting, but not deploying, even when it receives valid input values. This unexpected behavior has caused frustration and delays for these users.

Screenshot of the Issue

Here’s an example of what a screenshot might look like:

[Insert Screenshot of Remix Smart Contract, Gas Limit, Ether Amount]

As you can see in this image, the contract is designed to accept two parameters: value and gasLimit. However, when the user does not send any value (represented by the empty box), the contract reverts with an error message. But what happens when a valid input value is provided?

Gas Limit and Ether Amount

The screenshot also shows that the gas limit and Ether amount are included in the transaction data. This information is crucial to understanding the issue.

When a user sends a valid value (e.g., 100 ether) without specifying a gas limit, the contract attempts to deploy itself, which triggers the gas limit checks. However, since no gas limit was provided, the contract reverts with an error message.

Deploying Without Input

If we send a valid input value (e.g., 500 ether), the contract deploys successfully, and the transaction is executed without any issues.

Why This Issue Occurs

The cause of this issue is likely related to how the Ethereum Virtual Machine (EVM) handles gas limits and the value parameter. According to the EVM’s guidelines, when no value is provided for the value field, it defaults to 0 ether. However, if a valid input value is received, the contract should deploy successfully.

Workaround

To resolve this issue, users can try the following workaround:

  • Provide a gas limit: When sending a valid input value, include a non-zero gas limit in your transaction data.

  • Use the value field without a specified limit

    : If you do not want to specify a gas limit for the value field, ensure that it is empty.

Conclusion

In conclusion, this issue with Ethereum contracts reverts but not deploys when input values ​​​​are provided is a common problem for developers. By understanding the cause of this issue and applying the workarounds outlined above, users can resolve these issues and get their smart contract deployment processes running smoothly.

We hope this article has been helpful in shedding light on this issue and providing solutions to your problems as an Ethereum developer. If you have any further questions or concerns, please do not hesitate to ask.
