Metamask: Is it possible for sendTransaction to return an empty hash from MetaMask while isSuccess is true

Title: The mystery of empty hash: can Sendransazion return an empty hash from Metamask?

Introduction:

While we continue to build and integrate decentralized applications (APPS) in our digital wallets, a common problem that can arise is the return of an empty hash to certain scenarios. In this article, we will deepen a potential problem with Sendransation in Metamask, in which the sending of a transaction may not successfully complete despite the flag ‘Hesucesss’ which returnstrue'. We will explore what this behavior causes and examine if there are alternative solutions.

The problem: empty hash

When a user tries to send a transaction using Metamask, the resulting hash can be empty or indicate that the transaction has not been successful. This might seem at the beginning counterintuitive, but it is essential to understand the context in which "Sendtransation" returns an empty hash.

For example, if two users have the same private key and send a different input transaction (for example, 0x123abcde5678901Abcdef), Metamask will return an empty hash. This is because the metadata of the transactions do not contain the user's input data, necessary for the creation of successful transactions.

Flag of emission: a false positive?

The FlagHesucesss’ in Metamask indicates if the transaction has been performed correctly. However, it seems that this flag may not always reflect the state of the transaction carefully.

While an empty hash could be a clear indication of bankruptcy, the Hesuces' flag could potentially return true even if the transaction was not successful. This could lead to unexpected behavior or user confusion.

Simplified example: Code fragment

To better understand this problem, we consider a simplified example using react and wagmi.

jsx

Import {UseMetamask} from ‘@wagmijs/wagmi’;

Import MetamaskProvider from ‘./metaMaskProsider’;

Function App () {

Const {Error, Essuces, Sendransation} = UseMetamask ();

IF (! Error & & & &ys Essuces) {

Console.log (‘subsequent!’);

Sendransation ({a: ‘0x123abcde5678901Abcdef’, Value: 1});

}

return (

{/ Error message /}

{Mistake?

Error: {error.message}

: null}

sendtransation ({a: ‘0x123abcde5678901Abcdef’, Value: 1})}

Send transaction

);

}

Export the default app;

`

In this simplified code, if the FlagEssucesssreturn true and there is no error message, it might seem that the transaction has been sent correctly. However, without verifying the actual return value of “Sendransation”, we cannot confirm whether the transaction completed or not.

Conclusion:

The potential problem with empty hash in metamask transactions is largely due to the complexity of the interaction between the user’s portfolio and the underlying blockchain network. While the `Hesuces’ flag provides valuable information on the success of a transaction, it may be necessary to update or integrate from further checks to carefully determine if the transaction has been successful.

To mitigate this problem, developers can implement an additional logic in their DAPs to ensure that the user is informed when a transaction fails. This could entail the display of an error message instead of returning an empty hash.

Solutions and solutions:

• Implementation of additional logic:

  Users must be informed about any errors or problems relating to the sending of transactions.

2

• Return error messages: instead of returning an empty hash, DAPPS can return error messages with information on what has gone wrong.
