Understanding Why Your From Address Changes When Signing An Ethsign Transaction

When it comes to creating and signing ethereum transactions using web3.js, one of the most frustrating issues that developers Encounter is the unpredictable behavior of their from addresses. In this article, we’ll delve into why this happens and provide some troubleshooting steps to resolve the issue.

The Problem: Unpredictable from Addresses

In Ethereum, Each Address Has A Unique Identifier Known As An Ethereum Address Or “From” Address. These Addresses are generated using complex mathematical algorithms and are used to identify and track transactions on the blockchain. However, when you create a new transaction using web3.js, the from address changes randomly.

Why Does this Happen?

The Reason Behind This Behavior is due to the way Ethereum’s Smart Contract Functionality Works in Conjunction with its token System. When you sign an ethsign transaction (a type of signed message that contains signature and a payload), the from address is calculated based on the payload. However, Since web3.js relies on External Data Sources Like Etherscan or Infura to Fetch Information about the contract You’re interacting with, There are Several Factors That Can Contribute to this Unpredictability:

* Data fetching delay : When your application fetches data using external apis like etherscan or infura, it may take some time for the data to be processed and returned. This delay can result in a new from address being generated.

* API Response Errors : API Responses can Sometimes Return Errors That affect the calculation of the from address. If an error occurs while fetching data, your application may receive an incorrect or stale response, leading to unpredictable from addresses.

Gas ​​prices and fees : Gas prices and transaction fees can also Impact the accuracy of the from address. In some cases, High Gas Prices or Fees May Cause Your Application to Request A New From Address.

Troubleshooting Steps

To resolve this issue, you can try the following:

• Check for Data Fetching Delay

  : Ensure that your web3.js Application is Waiting for External Data Sources Like Etherscan or Infura Before Attempting to Sign Transactions.

• Verify API Response Errors : If an error occurs while fetching data, review the api response and ensure it’s accurate and relevant to your application.

• Gas ​​prices and fees monitor: Adjust gas prices or fees as needed to minimize the impact on from address accuracy.

By Understanding the Root Cause Issue and Implementing These Troubleshooting Steps, You Should Be Able To Resolve The Unpredictable from Addresses Associated With Signing Ethsign Using Web3.js.

Example use case

Here’s an Example of how you can modify your code to handle unexpected from addresses:

`Javascript

Async Function Createtransaction (Payload) {

// calculate the from address based on the payload

Constromaddress = calculateromaddress (payload);

Try {

// Sign the Transaction Using Web3.js

Constatedtransaction = Await web3.eth.sign transaction ({from: fromdaddress});

// Send the Transaction to Ethereum

Const txhash = Await web3.eth.endSignedTransaction (signed transaction.Rawtx);

console.log (‘Transaction sent Successful:’, Txhash);

} Catch (Error) {

console.error (‘Error Creating or Sending Transaction:’, Error);

}

}

// Call this function with a payload to create and sign a transaction

Createtransaction (Payload);

`

By Incorporating These Steps, You Should Be Able to Resolve the Issue of Unpredictable from Addresses When Signing Ethsign Transactions Using Web3.js.
