Ethereum: Bytes validation error while transferring ERC20 tokens while using ethereumjs/tx

Ethereum Bytes Validation Error While Transferring ERC20 TOKENS

As an Ethereum development, you are likely familiar with the complexities of interactive with the Ethereum blockchain. However, when it comes to transferring ERC20 tokens using the Ethereumjs library, you may encounter a rare and frustrating issue: a bytes validation error.

In this article,

The problem

The error message Specifically

The Code

Code:

`JavaScript

Const tx = New Web3.eth Tranaction ({

from: ‘Youdress’,

To: ‘RecipientAddaddress’,

Value: ‘0x2,248,191,131,170,54,167,20,138,49,48 …’, // Bytes Validation Error

});

`

Notice the value field being set to a string contalid byte array (0x2,248,191,131,170,54,167,20,138,49,48 ...). This is likely due to the way you’re parsing or encoding your ERC20 token data.

The Fix

The value is properly formatted as a hexadecimal string. Here are some steps to take:

1.

2.

JavaScript

Const tokendata = {

// …

};

Const hexvalue = Buffer.from (Tokendata, ‘Hex’);

tx.value = hexvalue.tostring (‘hex’); // Assume you have this library or implementation

`

• Check for encoding issues

  : Ensure that any binary data is properly encoded

4.

Best Practices

To avoid this issue in the future:

• Always Verify Your Token Data Before Sending It Over The Network.

• Ethers.

Example Use Case

Here’s an updated example code snippet that demonstrates how to fix the issue:

`JavaScript

Const Web3 = Require (‘Web3’);

Const ethers = Require (‘Ethers’);

Const Web3 = New Web3 (New Web3.providers.httpprovider (‘

Async Function Main () {

Const address = ‘Youdrress’;

Const recipientdaddress = ‘RecipientAddrress’;

try {

Const tx = New Ethers.transactions ({

From: Address,

To: RecipientAddarress,

Value: ‘0x2,248,191,131,170,54,167,20,138,49,48 …’, // Bytes Validation Error

});

await web3.eth.sendtransaction (tx);

} Catch (Error) {

Console.Error (Error);

}

}

slender ();
