Ethereum: Binance error -1102 – Mandatory parameter “Signature” was not sent, it was empty/null or unfair
As an increasing number of users approach the cryptocurrency store on platforms such as binance, developers are becoming more and more important to ensure that their automatic trading robots are working properly. However, questions can occur with Ethereum API when performing these tasks, which leads to unexpected mistakes.
An ordinary error that occurs during this procedure is associated with the signature parameter that requires Ethereum API. In this article, we will explore the details about what causes this mistake and we will provide steps on how to solve it.
understanding code error -1102
Error -1102 usually indicates a problem with the signature of demand, which is an essential component of cryptographic transactions in the Ethereum ecosystem. The parameter “Signatureis used to verify the identity and authentication insurance of the sender when performing blockchain transactions.
When you meet this error code, it is crucial to recognize the foundation cause:
* empty/nult or malfused signature : This could be due to the wrong management of signature information or the missing data to be included in the transaction request.
* The required parameters are missing : Ensure that all the necessary details are present and calculated during the transaction process.
Problem solving
To solve this problem, follow these steps:
Step 1: Check your signature information
First, make sure you use the correct "Signature" data when performing transactions. The signature is usually the hash of your public key in0x ….
Step 2: Include the required parameters
When you send a transaction to the Ethereum network, make sure that all the necessary parameters are included:
* DIN
: Please specify the sender's address.
* to : List the recipient's address.
* Value : The quantity of cryptocurrency you want to send.
* Gas : Gas limit for transaction.
Step 3: Manage errors and exceptions
When performing transactions, it is crucial to send all the potential errors that can happen. This may include the signature verification, ensuring the necessary parameters or managing the exceptions thrown by the Ethereum API.
Example Code clip
Here is an example of a code clip that shows how to check the transaction with theETH_Signmethod and indicate the required parameters:
JavaScript
Const web3 = necessary ('web3');
Const web3 = New Web3 (New Web3provers.httpProvider ('
ASYNC Executransation function () {{{
Const sederaddress = '0x ...'; // replace -va with your public key
Const container = '0x ...';
Quantity const = 10;
Constant constant = 100000; // the specified value but adjust as required
Try {
Const TransactingSignature = Wait Web3.esth.Signtransation ({{{
Since: SoundRaddress,
to: recipient,
Value: Sum.Tosting (),
Gas: Gaslimit
});
Constarcts = web3.esth.sendsignadransation (transactingsignation.raw);
Console.log (signatransation.status);
} Capture (error) {
If (error.code === 1102) {{
Consoles.error ('insured insufficient or incorrect signature.');
} Else {
Throwing error;

Conclusion
In order to successfully execute transactions in the Ethereum network, it is crucial to treat errors and exceptions correctly. By checking the data “signatures, including the necessary parameters and treating potential mistakes, you can ensure the correct performance of your muzzle without meeting the ETHREUM API.
