Title: Adding Native Coin Blockchain Logo in MetaMask (visible for public) using EVM Layer 1 pre-EIP 1559 blockchain

Introduction

As a developer working on an EVM (Ethereum Virtual Machine) layer 1 blockchain that is pre-EIP 1559 compliant, you’re likely familiar with the importance of having a native coin or token integrated into your platform. One common question arises when it comes to adding the logo of this native coin in MetaMask, a popular web browser extension for Ethereum development. In this article, we’ll explore how to achieve this feat.

Understanding the Current Approach

The current method suggested by MetaMask’s support is through the wallet_watchAsset API. However, as you’ve noted, this approach doesn’t directly provide an easy way to add a native coin logo in MetaMask for public visibility. Instead of using this indirect route, we’ll delve into implementing the EVM layer 1 pre-EIP 1559 blockchain solution that allows for a more straightforward integration.

EVM Layer 1 Pre-EIP 1559 Blockchain Solution

To create an EVM layer 1 pre-EIP 1559 blockchain solution with native coin integration in MetaMask, you’ll need to:

• Set up your Ethereum network

  : Ensure you have an established Ethereum network set up for this project.

• Choose a compatible EVM layer 1 platform: Select an EVM layer 1 platform that supports pre-EIP 1559 compliance, such as Polygon (Matic), Binance Smart Chain (BSC), or Solana.

Implementing the Solution

Here’s how you can implement this solution in MetaMask:

Step 1: Install a Web3 Library

First, install a web3 library that provides an interface to interact with the Ethereum network. Popular options include Web3.js, Ethers.js, and Truffle Hub.

Step 2: Create an EVM Layer 1 Wallet

Create a new wallet on your platform of choice for this project. You’ll need to generate an address and a private key for each user participating in the Ethereum network.

Step 3: Configure MetaMask to Use Your Custom Web3 Library

Once you’ve created a custom web3 library, configure MetaMask to use it for interacting with the Ethereum network. This involves setting up your custom eth provider using your library’s API.

Step 4: Integrate with EVM Layer 1 Platform

Use your custom web3 library to interact with the EVM layer 1 platform. You can then use this interface to retrieve the blockchain data, including the native coin information and logo.

Code Example

Here’s a basic example of how you could implement these steps in JavaScript using Web3.js:

// Import necessary libraries

const web3 = require('web3');

const EthersProvider = require('./customEthersProvider');


// Create a new Ethereum provider for our custom library

const provider = new EthersProvider({

  network: 'Polygon', // Replace with your platform's network name

});


// Create a new Web3 instance with the provider

const web3Instance = new web3(provider);


// Function to get native coin logo in MetaMask

async function getCoinLogo() {

  const tokenAddress = '0x...'; // Replace with your native coin address

  const web3Instance = await web3Instance.eth.getAccount('0x...');

  const accounts = await web3Instance.eth.getAccounts();


  for (const account of accounts) {

    if (account.toLowerCase().includes(tokenAddress.toLowerCase())) {

      return account;

    }

  }


  // Return null if no native coin found

  return null;

}


// Main entry point to get the native coin logo in MetaMask

async function main() {

  const tokenLogo = await getCoinLogo();

  console.log(tokenLogo);

}

Conclusion

By implementing a custom EVM layer 1 platform with pre-EIP 1559 compliance and integrating it with a supported web3 library, you can easily add the native coin logo in MetaMask for public visibility.
