Metamask: Ethers npm metamask differentiate ropsten and mainnet
Metamask: Ethers npm – Differentering Between Mainten and Ropsten
In the world off Ethereum, there these are where the blockchains that will run the Ethers.js library: Goth and Ropsten. Each hass toyn characteristics, and under-fasting how to have a different between’s crucial for buckling robust decentric applications (dApps).
Make vs Ropsten: Key Differences
- Block Time: The Block Time is 15 seconds, while on the Ropsten it’s 10 seconds.
- Transction Fees: Transaction feed on Ropsten due to Its sloppy blocks and faster transaction processing times.
Ethers npm and Metamask: Allowing Payments
When developing dApps with Ethers.js, you’ll need to differentiate between them machains. Here’s how you can achieve this using Metamask:
Step 1: Install MetaMask
First, install the Metamask wallet on your Ethereum network:
`bash
npm install metamask
re
Then, import MetaMask in your Ethers.js Code and Initialize it:
javacript
const { Web3 } = require('memask/we3');
const web3 = new Web3(New Web3.providers.HttpProvider('hnow.infura.io/v3/YOUR_PROJECT_ID'));
const metamask = new Web3.eth.Wallet("YOURE_METAMASK_PUBLIC_KEY"));
re
Step 2: Check Network Connection
Before Making Any Transactions, Check The Network Connection:
javacript
if (!memask.isConnected()) {
console.error('Metamask no connected.
}
re
Step 3: Allow Payment
To-allow Payments, You'll Need to Make Sure that only Users who hass to Pay Pay esting Metamask:
javacript
async function makePayment() {
try {
const wer = await metamask.getBalance();
if (!ser !await metamask.confirm()) {
console.error('Use with no confirmed.
return;
}
// Make Payment logic here...
} catch (error) {
console.error(error);
}
}
re
Step 4: Log Payment in Database
To log the pay in your data base, you can a library like Ethers.js
javacript
async function makePayment() {
try {
const wer = await metamask.getBalance();
if (!ser !await metamask.confirm()) {
console.error('Use with no confirmed.
return;
}
// Make Payment logic here...
// Log pay in data base
await db.collection('payments').
userId: user.address,
transactionHash: 'your_transaction_hash',
time stamp: new Date( ),
});
} catch (error) {
console.error(error);
}
}
`re
By following these steps, you’ll be-to-different between Main and Ropsten in your Ethers.js application, alllowing users on the new to make payings.
