Metamask: Getting transaction history via Ethers.js

Showing of received transactions in metamask using ethers.js

As a developer that builds on the Ethereum blockchain, you are probably familiar with the popular metamask for item pocket providers. However, it can be a challenge to report a transaction history. In this article, we will examine how to access and display transactions received with Ethers.js, the JavaScript library for interaction with the Ethereum blockchain.

Why is the display of transaction history required?

The display of transaction history is of crucial importance for various applications, such as: B.:

* Arrivals: to keep an eye on incoming and outgoing transactions.

* Market analysis tools: to visualize the purchase and sales activity over time.

* Security audits: To ensure that items are not used for illegal activities.

Step-by-step instructions for displayed transactions

To display received transactions in your metamask letter bag with Ethgers.js, you need:

• Install Ethhers.js : Lead npm install ethers.js orAdarn Add ethers.js' to your project directory.

• import the library and set up a provider : Create an instance of the Ethereum provider usingether.providers.jsonrpcprovider. For example:

JavaScript

Const Provider = new ethers.providers.jsonrpcprovider (‘

`

Replace your_project_id with your actual Infura project -ID.

• Get the item of the item : Import the Metamask letter pocket body with ether.wallet.fromprivatekey. You have to charge a private key from a file or a local item of the wallpaper:

`JavaScript

Const Wallet = Waits Ethher.wallet.Fromkey (private key);

`

Replace “Private Key” with your actual private key from Ethereum.

• Get the transactions received : Use the provider’s instance to get a list of received transactions for the address given with the 'ethers.providers.web3Provider API:

`JavaScript

Asynchrical function of trecedtransactions () {

Const web3 = new ethers.providers.jsonrpcprovider (‘

Const Wallletdress = ‘0x … YourWallertaddress …’;

attempt {

Const receiving transactions = waiting for web3.eth.

Graf: 100,

from block: ‘ultimately’,

Toblock: ‘Last’,,

});

Return received transactions.map ((transaction) => transaction.transaction);

} Catch (error) {

console.error (error);

return [];

}

}

`

This code calls a list of transactions for the specified item of the item. You can then analyze and display these transactions.

• Show transactions

  

  : As soon as you have the transactions received, you can use Ethhers.js to create a visualization using the ether.providers.web3Provider API.

For example:

`JavaScript

Asynchrical function DisplayRecedtransactions () {

Const web3 = new ethers.providers.jsonrpcprovider (‘

Const Receive Transactions = WaTte Trecedtransactions ();

console.log (received transaction);

}

`

Example code

Here is a complete example that you can copy and insert it into your project:

`JavaScript

Import * as an ether from ‘Ether’;

Import {web3Provider} from ‘@web3 provider’;

// Set up the instance of the Ethereum providers

Const Provider = New Web3Provider (‘

// Get the item of the item and the private key (replace it with your own)

Const Privatey = ‘0x … YourwalletPrivatekey …’);

Const Wallletdress = ‘0x … YourWallertaddress …’;

Asynchrical function of trecedtransactions () {

attempt {

Const Receive Transactions = WaTte Provider.eth.GetTransactionhistory (Walletdadress, {

Graf: 100,

from block: ‘ultimately’,

Toblock: ‘Last’,,

});

Return received transactions.map ((transaction) => transaction.transaction);

} Catch (error) {

Console.
