METAMASK: NPM ethers – differentiating between Mainnet and Ropsten
In the world of Ethereum, there are two main blockchains that are executed at the top of the Ethers.js: Mainnet and Ropsten Library. Each has their own unique characteristics, and understanding how to differentiate between them is crucial to building solid decentralized applications (DAPP).
Mainnet vs Ropsten: Key differences
* Block time : The block time in Mainnet is 15 seconds, while in Ropsten they are 10 seconds.
* Transaction rates : Transaction rates are lower in Ropsten due to its smallest block size and faster transaction processing times.
NPM and Metamk ether: allowing payments
When developing DAPPs with Ethers.js, you will need to differentiate between the two Mainchans. This is how you can achieve this using MetamSk:
Step 1: Install MetamSk
First, install the metamask wallet on your Ethereum network:
`Bash
NPM Install Metamask
Then, Metamk amount in its Ethers.js and initialize code:
JavaScript
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 the network connection
Before making any transaction, check the network connection:
JavaScript
if (! MetamSk.isconnected ()) {
Console.error ('MetamSk not connected. Connect first');
}
Step 3: Allow payment
To allow payments, you should ensure that only users who have confirmed in Mainnet can pay using Metamask:
JavaScript
Async Function Makepayment () {
attempt {
Const user = alea metamask.getbalance ();
if (! User ||
Console.error ('The user has not confirmed. Please confirm first');
return;
}
// Make payment logic here ...
} capt (error) {
Console.error (error);
}
}
Step 4: Registration record in the database
To record the payment in your database, you can use a library as Ethers.js or a personalized solution:
JavaScript
Async Function Makepayment () {
attempt {
Const user = alea metamask.getbalance ();
if (! User ||
Console.error ('The user has not confirmed. Please confirm first');
return;
}
// Make payment logic here ...
// record the payment in the database
Wait dB.Collection ('payments'). insertone ({{
Userid: User.address,
Transactionah: 'Your_transaction_hash',
Time brand: new date (),
});
} capt (error) {
Console.error (error);
}
}
`
Following these steps, you can differentiate between Mainnet and Ropsten in their Ethers.js application, which allows users in the latter to make payments without registering them in Metamk.
