Metamask: ERC-681 data field ignored by Metamask

MetaMask Error: ERC-681 Data Field Ignored

As a MetaMask user, you probably know how important it is to build and manage decentralized applications (dApps) on the Ethereum blockchain. However, when trying to receive funds or search for transactions using your MetaMask wallet, a common problem arises: the data field is not included in the transaction.

ERC-681 Data Field Problem

ERC-681 is a set of standards for managing and validating data fields in 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.

Metamask Issue

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 scan transactions using a Metamask wallet, it will fail.

Creating a QR Code Solution

To overcome this issue, 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 (e.g., in the Metamask repository).

• 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 the new QR code as input to the dApp. You can also scan transactions using your QR code. You can send funds.

Code example

Here is an example of how you could 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 a hexadecimal value
const qrCode = new QRCCods({
text: "Scan ${hexDataField} to receive funds",
colorDark: "#000000",
colorlight: "#ffffff",
});
// Use MetaMask to receive funds or scan QR code transactions
await account.qrCodeScanner(qrCode);

Conclusion

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