Title: The mystery of empty hashs: can sandtransction return a hollow hash from metask?
Introduction:
As we continue to build and integrate decentralized applications (DAPP) into our digital wallet, a general problem that may arise is the return of empty hash in certain scenarios. In this article, we deepen a possible problem with “Sendtransction in Metamark, where the transaction has not been successfully completed, despite the flag isuccess” returns. We examine what causes this behavior and examine that there are solutions.
Problem: Has a blank
When the user tries to send a transaction using MetASK, the resulting hash may be empty or indicates that the transaction was not successful. At first, this may seem contradictory, but it is essential to understand that “Sendtransction” returns an empty hash.
For example, if two users have the same private key and send a transaction with different inputs (such as 0x123abcde5678901abcdef), MetASK returns an empty hash. The reason for this is that the metadata of the transaction does not contain the user’s entry information, which is required to create successful transactions.
Issuccess flag: positive false?
The “Issuccess” flag in Metask indicates that the transaction has been successfully implemented. However, this flag does not seem to reflect the status of the transaction.
Although the empty hash can clearly indicate the failure, the “Issuccess” flag may be true, even if the transaction was not successful. This can lead to unexpected behavior or user disorder.
Simplified example: Code -Fragmentum
To understand the problem better, consider the simplified example with React and Wagmi.
`Jsx
Import {usmememark} from '@wagmijs/wagmi';
Import metaskprovider from '/metamarkprovider';
Function App () {
const {error, issuccess, serudtransction} = usmemask ();
if (! fault && issuccess) {
console.log ('success!');
Sendtransction ({at: 0x123ABCDE5678901ABCDEF ', Value: 1});
}
Return (
{/ Error message /}
{fault?
Error: {Error.message}
: Null}
!
Send the transaction
);
}
Implicit application for export;
`
In this simplified code, if the “ISSUCCESS” flag is true and there is no error message, the transaction seems to have been successfully sent. Despite checking the actual return value of the Sendtransction, we cannot confirm whether the transaction is completed or not.
Conclusion:
In Metamark -transactions, a possible problem with empty hashs is largely due to the interaction complexity between the user wallet and the basic blockchain network. Although the “Issuccess” flag offers a valuable perspective on the state of success, you may have further checks to update or fill in to accurately determine that the transaction is successful.
To alleviate the problem, developers can perform additional logic in DAPP to ensure that the user is informed when a transaction fails. This may include displaying an error message instead of returning an empty hash.
Solutions and solutions:
- Perform an additional logic:
Users must be informed about the errors or problems of sending transactions.
2.
- return error messages: Instead of returning blank hash, Dapps can return error messages with poor information.
