Metamask: ERC-681 data field ignored by Metamask

MetaMask Error: ERC-681 Data Field Missing

As a MetaMask user, you probably know how important it is to create and manage decentralized applications (dApps) on the Ethereum blockchain. However, when you try to receive funds or scan transactions with a MetaMask wallet, a common problem arises: The data field is not included in the event.

ERC-681 Data Field Issue

ERC-681 is a set of standards for managing and validating smart contract data fields 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 using ERC-721, ERC-1155, or other libraries, it is not uncommon for the data field to be missing.

Problem with Metamask

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

Creating a QR Code Solution

You can solve this problem by creating a simple solution using QR codes. Here are the steps:

• Create a new wallet address: Create a new MetaMask wallet and create a new account.

• Represent the data in hexadecimal: Write down the hexadecimal value of the data field and store it securely on the blockchain (e.g. Metamask storage).

• Create a QR code: Use a tool like QR Code Generator to create a QR code from a hexadecimal value.

• Using 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 with their QR codes and send the amount.

Sample code

Here is an example of how you can implement this solution in JavaScript:

const MetaMask = request("metamask");
// Create a new wallet
const account = await MetaMask.createAccount();
// Get the hexadecimal representation of the data field
const hexDataField = "0x..." + {hex};
// Create a QR code from a hexadecimal value
const qrCode = new QRCode({
text: "Search ${hexDataField} to get money",
color Dark: "#000000",
color Light: "#ffffff",
});
// You can use MetaMask to receive money or scan transactions with a QR code
await account.qrCodeScanner(qrCode);

Conclusion

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