Ethereum: How to check if transaction belongs to Uniswap using etherscan api?

Checking uniswap transactions with Etherscan API

As a Developer, IT is Essential to Prove the Credibility and Legitimacy of Transactions on the Ethereum Blockchain. One of these usage cases is to check that a particular transaction belongs to the uniswap replacement.

In this article, we show how to use etherscan api to filter out uniswap transactions to a particular address.

Prerequisites

• You have an account on etherscan and have access to api.

• The address you want to check is related to a uniswap account.

STEP 1: SET THE ETHERSCAN API Request

To use Etherscan API:

• Create a New API Request by clicking on “Settings” (Gear Icon) and Selecting “API -K”.

• Complete The Necessary Information:

* Name : Enter the API’s request unique name.

* Description : Letterly Describe What this API is Doing.

* Endpoint : Enter the Etherscan API Endpoint for the requested data that https: //api.etherscan.io/api? Module = account and action = tokens & address = 0x534A0076FB7C2B1F83FA21497429AD3BD7587.

* Filters : Set the filter to unniswap".

Step 2: Enter the Etherscan API Request code

Here's an Example of how to send an api request using javascript using the "fetch" api:

JavaScript

ASYNC Function Checkuniswaptransactions (Title) {

Const url = ' + Address;

Try {

Constille = Waiting for Fetch (URL);

if (! response.ok) {

Throw a New Error (Troubleshooting Transactions: $ {responsse.statural});

}

Consta data = Waiting for response.json ();

console.log (data);

} Catch (Error) {

Console.error (error.message);

}

}

Step 3: Send the API Request and Analyze the Answer

Replace “Checkuniswapp transections” with your own function:

`JavaScript

Checkuniswap transactions ('0x534A0076FB7C2B1F83FA21497429AD7AD3BD7587')

.Then ((transactions) => {{{

console.log (transactions);

})

.catch ((error) => {{{

Console.error (error.message);

});

Example output

API Returns an object with transaction data. For Example:

`Json

{{{

"Status": 1,

"Result": [

{{{

"From": "0x534A0076FB7C2B1F83FA21497429AD7AD7AD7AD7587",

"To": "0x1234567890abcdef",

"Value": 10000000,

"Gas": 2000000,

"GASPRICE": 20000

}

]

}

In this example, The Transactions are denoted “status” Equal to 1, Indicating Success. You can be the obtained data to filter and verify the authenticity of these transactions.

Tips and variations

• Change the API URL Accordingly to Filter the Specificated Device Types (Such as tokens or funds).

• You can add additional filters or parameters to Further Refine the search results.
