Understanding why your address changes. from Since signing an EthSign transaction
When it comes to creating and signing Ethereum transactions using Web3.js, one of the most frustrating issues developers face is the unpredictable behavior of their addresses. In this article, we will explore in more detail why this happens and provide some troubleshooting steps to resolve the issue.
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 creating a new transaction using Web3.js, the from address changes randomly.
Why does this happen?
The reason for this behavior is 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 the sender’s signature and a payload), the original address is calculated based on the payload. However, because Web3.js relies on external data sources such as Etherscan or Infura to retrieve information about the contract you are interacting with, there are several factors that can contribute to this unpredictability.
- Data Fetch Delay: When your application retrieves data using external APIs such as Etherscan or Infura, it can take some time for the data to be processed and returned. This delay can result in a new address being generated from.
- API Response Errors: API responses can sometimes return errors that affect the calculation of the sender’s address. If an error occurs while retrieving the data, your application may receive an incorrect or outdated response, which will lead to unpredictability from the addresses.
- Gas Prices and Fees: Gas prices and transaction fees can also affect the accuracy of your shipping address. In some cases, high gas prices or taxes can cause your request to be rejected. to request a new address.
Troubleshooting Steps
You can try the following steps to resolve this issue.
- Check data retrieval latency: Check your application. Web3.js waits for external data sources, such as Etherscan or Infura, before attempting to sign transactions.
- Check API response errors: If an error occurs while retrieving data, review the API response and make sure it is correct and appropriate for your application.
- Monitor gas prices and taxes: Adjust gas prices or taxes as needed to minimize the impact on address accuracy.
By understanding the root cause of this issue and following these troubleshooting steps, you should be able to resolve the address unpredictability associated with signing EthSign transactions using Web3.js.
Use Case Example
Here is an example of how to modify the code to handle unexpected addresses.
async function createTransaction(payload) {
// Calculate the sending address based on the payload
const fromAddress = calculateFromAddress(payload);
try {
// Sign the transaction using Web3.js
const signedTransaction = await web3.eth.signTransaction({ from: fromAddress });
// Send the transaction to Ethereum
const txHash = await web3.eth.sendSignedTransaction(signedTransaction.rawTx);
console.log('Transaction successfully sent:', txHash);
} catch (error) {
console.error('Error creating or sending transaction:', error);
}
}
// Call this function with the payload to create and sign the transaction
createTransaction(payload);
By including these steps, you should be able to resolve the unpredictable address issue when signing EthSign transactions using Web3.js.
