Metamask: Ethers NPM – Fay Mainnet and Ropsten
In Ethereum World Two Block Running on the Versh Bibliate Ethers.js: Mainnet and Ropsten. Each has its unique characteristic and the present -ending of the renewed deentalized attachments (DAPPS).
Mainnet Anti Ropsten: Display in Key
* Time block
: Time Mainnet block is 15 seconds, and Ropsten – 10 seconds.
* Translation fee : transaction fee at Ropsten in the Cash of the Less Promoter and Better Time Cabbot Transaction.
Ethers NPM and Metamask: Enable Consigns
DAPS DAPPS DAPPS DUPS DUPCHY HAPPY ENTER ETHERS.JS. Here’s how you can do this, use Metamask:
Shag 1: Install Metamask
Turned up your Metamask in the Ethereum Network:
`Bash
NPM Install Metamask
`
Passes Metamask in Ethers.js and Initialize it:
`Javascript
Const {web3} = need to ('@metamask/web3');
Const Web3 = New Web3 (New Web3.providers.httpprovider ('
const metamask = new web3.eth.wallet ("Your_metamask_public_key");
Shag 2: Check the network connection
Check the network connection before the transaction of the transaction:
`Javascript
IF (! Metamask.isconnected ()) {
Console.error ('Metamask is not connected.
}
Shag 3: Turn the payment
To include the plates, you need to realize that only the policies, which are confirmed on Mainnet, can pay with help metamask:
`Javascript
Ashron function MakePayment () {
Ask {
Const User = Waiting Metamask.getBalance ();
If (! User ||! Jewish Metamask.confirm ()) {
Console.error ('' The policeman did not confuse the crop, confuse the healer. ');
Recruit;
}
// Production Logiki Platage here ...
} Catch (error) {
Console.error (Oshbak);
}
}
Shag 4: Designion in the database
In the database you can use the catalog, such as ethers.js, if the voit in your plate: or unique resolution:
`Javascript
Ashron function MakePayment () {
Ask {
Const User = Waiting Metamask.getBalance ();
If (! POLUTER ||! Dodge Metamask.confirm ()) {
Console.error ('' The policeman did not confuse the crop, confuse the healer. ');
Recruit;
}
// Production Logiki Platage here ...
// Entry into the database
In db.collection ("Platters"). Insertone ({{
Userid: User.address,
TRANSECTIONHASH: 'Your_transction_hash',
Time Time: New Date (),
});
} Catch (error) {
Console.error (Oshbak);
}
}
The following is a shague, you can calculate Mainnet and Ropsten in Ethers.js, allowed after the policeman to make a salary without the submission of the statement on Metamask.
