Finding recent events according to the amount: Guide
In Ethereum, finding events according to the amount can be a challenging task, especially when dealing with large quantities or complex transaction structures. In this article, we explore ways to find recent events according to the amount.
What’s the problem?
When you want to look for a specific event according to the quantity, you can face problems such as:
- Missing or incomplete event data
- Invalid or outdated transaction records
- Difficulty in cleaning and drawing relevant information
Method 1: Use Etherscan.io API
Etherscan.io is a popular platform that provides access to the Ethereum block chain. One of his qualities is the ability to find events according to the amount.
Here’s an example of how to use the Etherscan application subscription:
- Install the
Etherscanpackage using NPM or thread:NPM Install Ethercanorthread Add Ethercan
- Eteri -Terscanapi “Class Eterscan”
- Make an API -AS key Ethereum application subscription (if necessary)
- Use the “Search RanSbyquantity” method to search according to the number of events
Example Code
`Javascript
Import {Ethercanapi} ‘Etherscan’;
Const Api = New Etherscanapi ({{{
Mirikey: ‘
});
// Find events according to the number
API.SEARCHTRANSBIQIIQUANTY (
{
Survey: ‘x BTC’,
Offset: 0,
Border: 100, // To adjust the limit as needed
Mozhlo
(Error, Result) => {
If (error) {
Console.error (error);
} Else {
Const transaction = result.transactions;
// process and show events information

Iche
)

Method 2: Using Web3.JS and Skripper
Another approach is the use of the "Web3" library in Javascript together with the script to look for events according to the amount.
Here's an example of a code clip that indicates how you can use a script to find events:
Javascript
Const Web3 = Required (‘Web3’);
// Replace URL -Thereum node
Const nodeurl = ‘
Async Function SearchtransbySbyquantity () {{{
// Initializing the Web3 Service Provider
Const provider = new web3.providers.httpprovider (nodeurl);
// Create a new contract
Const agreement = wait davara.eth.getcontract (‘0x …’);
// Complete the questionnaire with a smart contract with a script
Const tx = wait for the contract.Method.searchtransbysbyquantity (10) .send ();
Iche
Searchtransbysbyquantity (). then ((result) => {
if (results.status! == ‘0x’) {)
Console.error (result);
Iche
});
``
Method 3: Manual Transaction Analysis
Another approach is to analyze event information manually to draw relevant information.
- Check that events metapodate if you have traces such as sender or recipient address
- Find all large quantities of events (eg> 100 BTC)
- Analyzes the event’s time and block number
conclusion
Finding recent events according to the amount can be challenging, but there are several approaches that you can win to overcome these restrictions.
Using one of the above methods or by combining multiple techniques, you should be able to successfully search for events with certain quantities.
