Ethereum’s contract problems: Restore, but don’t distribute
As an Ethereum developer, you probably encountered problems with the distribution and performance of an intelligent contract. In this article, we will deepen the details of the latest problem that affected users like you.
problem
We received reports from several users who have undergone special behavior in their Ethereum contracts. The problem is provided for by a contract that still restores, but not distribute, even if it receives correct input values. This unexpected behavior caused frustration and delays for these users.
Screenshot of the problem
Here is an example of how a screenshot can be:
[Enter the remix school intelligent contract, gas limit, additional amount]
As you can see in this picture, the contract aims to accept two parameters: `value 'is gaslimit'. However, when the user does not send any value (represented by an empty field), the contract returns an error message. But what happens when the correct input value is given?
gas limit and the amount of ether
The screenshot also shows that the gas limit and the amount of ether are included in the transaction data. This information is necessary to understand the problem.
When the user sends the correct "value" (for example, 100 ether) without specifying the gas limit, the contract is tried to spread, which triggers the gas limit control. However, since the gas limit has not been given, the contract restores an error message.
Distribution without entry
If we send the correct input value (e.g. Ether 500), the contract is disseminated correctly and the transaction is performed without problems.
why this problem occurs
The reason for this problem is probably correlated with how the Ethereum virtual machine (EVM) manages gas limits and the "value" parameter. According to the AVM guidelines, when there is no value for the "value" field, it is set to 0 ether. However, if he receives the correct input value, the contract must be properly widespread.
WOURAD
To solve this problem, users can try the following solution:
- Give the gas limit : When sending the correct input value, take into account the gas limit other than zero in transaction data.
- Use the field value` without a specific limit : If you do not want to determine the gas limit for the range, make sure it is empty.
Application
To sum up, this problem with Ethereum contracts is restored, but it is not distributed when input values are given, it is a common problem for programmers. Understanding the reason for this problem and using alternative solutions presented above, users can solve these problems and obtain the distribution processes of an intelligent contract in performance without problems.
We hope that this article was useful to shed light on this topic and provide solutions to your problems as an Ethereum developer. If you have further questions or doubts, do not hesitate to ask.
