Metamask Error: ERC-681 Data Field Ignored

Metamask: ERC-681 data field ignored by Metamask

As a MetaMask user, you probably know the importance of being able to build and run decentralized applications (dApps) on the Ethereum blockchain. However, when trying to receive funds or search for transactions using the Metamask wallet, a common problem occurs: the data field is not included in the transaction.

The Problem with ERC-681 Data Fields

ERC-681 is a set of standards for managing and validating data fields within smart contracts on the Ethereum blockchain. The standard defines how these data fields are used to store and retrieve data from smart contracts. However, when implementing data fields in dApps using ERC-721, ERC-1155, or other libraries, it is not uncommon for the data field to be omitted.

The Problem with Metamask

When creating a transaction using MetaMask, the data field is set to 0x{hex}, where {hex} represents the hexadecimal representation of the data. Unfortunately, this metadata field is not included in the Ethereum blockchain smart contract code, which means that when you try to send funds or search for transactions using your Metamask wallet, it will fail.

Creating a QR Code Solution

To overcome this problem, you can create a simple solution using QR codes. Here are the steps:

  • Create a new wallet address: Create a new MetaMask wallet and set up a new account.
  • Get the hexadecimal representation of your data: Write down the hexadecimal value of your data field and store it securely on the blockchain (for example, in a Metamask vault).
  • Create a QR code: Use a tool like QR Code Generator to create a QR code from the hexadecimal value.
  • Use MetaMask to receive funds or scan transactions: When you receive funds, you can use your new QR code as input to your dApp. Alternatively, you can scan transactions using your QR code and send the funds.

Sample code

Here's an example of how you might implement this solution in JavaScript:

const MetaMask = require("metamask");

// Create a new wallet

const account = await MetaMask.createAccount();

// Get the hexadecimal representation of your data field

const hexDataField = "0x..." + {hex};

// Create a QR code from hexadecimal value

const qrCode = new QRCode({

text: Scan ${hexDataField} to receive funds,

darkColor: "#000000".

lightColor: "#ffffff"

});

// Use MetaMask to receive funds or scan transactions with QR code

wait account . qrCodeScanner ( qrCode ) ;

Conclusion

The problem of ignoring ERC-681 data fields in Metamask transactions can be frustrating, but there are solutions available. By creating a simple solution using QR codes, you can overcome this problem and receive funds or scan transactions using your MetaMask wallet.
