Failure to estimate the Ethereum gas: a problem resolving

As a developer, you probably encountered problems with the distribution of the intelligent contract based on Ethereum. A common problem is the failure of the gas estimate, which can cause distribution failures and reduced performance. In this article, we will deepen the reasons behind the failure of the gas estimate and provide a guide on how to solve problems and solve the problem.

What is the estimate of the gas?

The estimate of the gas is a process used by the Ethereum virtual machine (EVM) to estimate the amount of gas necessary to perform an intelligent contract. It is an essential step in the distribution process, as it helps developers to optimize their contracts for better performance and reduce the risk of implementation failures.

Why does the failure of the gas estimate occurs?

There are several reasons why a failure of the gas estimate could occur:

  • EIP-1559 Settings incorrect

    : If you use EIP-1559, a recent Ethereum improvement proposal, the gas limit or commissions settings may not meet the contract requirements.

  • The fluctuations of the price of the gas

    : the variations of the gas prices of the Ethereum network can cause gas estimation faults if you are not aware of the current gas price.

Symptoms of the failure of the gas estimate

If the estimate of the gas fails, it is possible to notice the following symptoms:

  • The distribution fails with an error of “non -valid transaction”.

  • The distribution of the contract takes a long time to be completed.

  • Receive frequent errors or warnings during the deployment.

  • Your use of the gas exceeds the allowed limit.

Problem resolution guide:

To solve problems and solve the failure of the gas estimate, follow these steps:

  • CONTROL EIP-1559 settings: verify that the EIP-1559 configuration is correct and corresponds to the contract requirements.

  • Perform a calculation of the gas estimate : uses tools such as Remix Eth or Trustro to perform a calculation of the gas estimate on the source code of the contract.

  • Check the size and complexity of the archive : confirm that the size of the contract storage and the complexity of the transactions are accurate.

Example of TX output

As you said, here is an example of Etherscan’s failed TX output:

`

0x ... (TX hash)

TX size: 1.44kb

Estimation of the gas has not succeeded.

In this example, the TX size is greater than the allowed limit, causing a failure to esteem the gas.

Force sending and burned eth

Before the strength to send the contract, it is advisable to try the following:

  • Reduce the gas limit : try to reduce the gas limit on the contract or fix a more conservative estimate.

2

  • Increases the storage dimension : increase the archiving dimensions of the contract, if necessary.

If sending the force fails again, try to burn a little and to see if it solves the problem:

0x ... (TX hash)

Burn 10000 Eth

Conclusion

The failure of the gas estimate can be frustrating, but understanding the reasons below and following these passages of resolution of the problems, you should be able to solve the problem. Remember to regularly check the EIP-1559 settings, the gas limit and the commissions settings to guarantee optimal distribution services.
