Metamask Error: ERC-681 Data Field Ignored
As a MetaMask user, you probably know the importance of being able to build and run decentralized appl壯陽藥
ications (dApps) on the Ethereum blockchain. However, when trying to receive funds or scan transactions using the Metamask wallet, a common problem occurs: 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 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 a data field to be omitted.
Metamask Issue
When creating a transaction using MetaMask, the “data” field is set to “0x{hex}”, where “{hex}” is 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 your Metamask wallet, the operation 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 a hexadecimal representation of your data: Write down the hexadecimal value of your data field and store it securely on a 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.
- 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 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 = wait MetaMask.createAccount();
// Get the hexadecimal representation of your data array
const hexDataField = "0x..." + {hex};
// Create a QR code from hexadecimal value
const qrCode = new QRCode({
text: Search for ${hexDataField} and get assets,
darkColor: "#000000",
lightColor: "#ffffff",
});
// Use MetaMask to receive funds or scan transactions using a 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. By creating a simple solution using QR codes, you can overcome this problem and successfully receive funds or scan transactions using your MetaMask wallet.
