Metamask: Ethers npm metamask differentiate ropsten and mainnet

Metamask: Ethers npm – Differences Between Mainnet and Ropsten

In the world of Ethereum, there are two main blockchains that run on the Ethers.js library: Mainnet and Ropsten. Each has its own unique characteristics, and understanding how to differentiate them is crucial to building solid decentralized applications (dApps).

Mainnet vs. Ropsten: Key Differences

• Block Time: The block time on Mainnet is 15 seconds, while on Ropsten it is 10 seconds.

• Transaction Fees: Transaction fees are lower on Ropsten due to the smaller block size and faster transaction processing times.

Ethers npm and Metamask: Enabling Payments

When building dApps with Ethers.js, it is important to differentiate between the two main chains. Here’s how you can achieve this with Metamask:

Step 1: Install MetaMask

First, install the Metamask wallet on your Ethereum network:

npm install metamask

Then import MetaMask into your Ethers.js code and initialize it:

const { Web3 } = require('@metamask/web3');
const web3 = new Web3(new Web3.providers.HttpProvider('
const metamask = new Web3.eth.Wallet("YOUR_METAMASK_PUBLIC_KEY");

Step 2: Check your network connection

Before making any transactions, check your network connection:

if (!metamask.isConnected()) {
console.error('Metamask is not connected. Please connect first.');
}

Step 3: Allow payment

To allow payments, you need to make sure that only users who have confirmed in Mainnet can pay with Metamask:

async function makePayment() {
try {
const user = await metamask.getBalance();
if (!user || !await metamask.confirm()) {
console.error('User has not confirmed. Please confirm first.');
return;
}
// Do the payment logic here...
} catch (error) {
console.error(error);
}
}

Step 4: Recording the payment in the database

To record the payment in your database, you can use a library like Ethers.js or a custom solution:

async function makePayment() {
try {
const user = await metamask.getBalance();
if (!user || !await metamask.confirm()) {
console.error('User did not confirm. Please confirm first.');
return;
}
// Create payment logic here...
// Recording payments in the database
await db.collection('payments').insertOne({
userId: user.address,
transactionHash: 'your_transaction_hash',
timestamp: new Date(),
});
} catch (error) {
console.error(error);
}
}

By following these steps, you will be able to differentiate Mainnet from Ropsten in your Ethers.js application, allowing users of the latter to make payments without having to log in to Metamask.
