Ethereum: Binance Signature for this request is not valid error

Working with Errors and Signature Management in Ethereum Intelligent Contracts

Ethereum, you are probably familiar with the importance of correct misakes and signature management. “Binance signature” is not valid.

The Problem: Binance Signature

When creating a digital signature for Ethereum blockchain transaction, you must However, for the reasons for the security, the binanceapi does not provide direct access to the private key to the signator.

Code:CryptoModule

Crypto Here is an example fragment of code:

`JavaScript

Const crypto = requires (‘crypto’);

Const {signer} = crypto;

// replace with your own private key

Const privatekey = “your_private_key_here”;

// Define the Feature to be used to Sign Transactions

Async Functional Signature (Message) {

try {

// Create a New Copy of Signatures Using Binance API

Const signer = wait a new signature (privatekey);

// Sign the Transaction with the Signature

Synst signature = waiting signature.signmessage (message, “eth_sign”);

Return of Signature;

} Catch (Error) {

Console.Error (“Signing Transaction Error:”, Error);

Throwing error; // Re -throw the Error for Further Control

}

}

// sample use:

Async Function Main () {

try {

// Send a message to Ethereum Network

Const message = “hello, binance!”;

Const signature = wait signature (message);

Console.log (“Signature of Transaction:”, Signature);

} Catch (Error) {

Console.error (“Error:”, Error);

}

}

Tips for Successful Execution:

* Save your personal key

: Never share or expose your personal key publicly.

* use a reliable binance api conversion

:

* Test thoroughly : Check that your “crypto” module works as expected, including generating signatures for different messages.

“Binance Signature”, which is not a valid misake in the construction of intelligent contracts based on Ethereum.
