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

Checking Uniswap Transactions with the Etherscan API

As a developer, it is essential to verify the authenticity and legitimacy of transactions on the Ethereum blockchain. One such use case is to check whether a transaction belongs to the Uniswap exchange.

In this article, we will show you how to use the Etherscan API to filter Uniswap transactions for a specific address.

Prerequisites

• You have an account with Etherscan and can access their API.

• The address you want to check is associated with a Uniswap account.

Step 1: Set up an Etherscan API Request

To use the Etherscan API, you need to:

• Create a new API request by clicking on “Settings” (the gear icon) and selecting “APIs”.

• Fill in the required information:

• Name: Give your API request a unique name.

• Description: Briefly describe what this API does.

• Endpoint: Enter the Etherscan API endpoint for the requested data, which is

• Filters: Set the filter toUniswap.

Here is an example of how you can use JavaScript to send an API request using thefetchAPI:

async function checkUniswapTransactions(address) {
const url = ' + address;
try {
const response = await fetch(url);
if (!response.ok) {
throw new Error(Error fetching transaction: ${response.statusText});
}
const data = await response.json();
console.log(data);
} catch (error) {
console.error(error.message);
}
}

Replace checkUniswapTransactionswith your own function:

checkUniswapTransactions('0x534a0076fb7c2b1f83fa21497429ad7ad3bd7587')
.then((transactions) => {
console.log(transactions);
})
.catch((error) => {
console.error(error.message);
});

{
"status": 1,
"result": [
{
"from": "0x534a0076fb7c2b1f83fa21497429ad7ad3bd7587",
"to": "0x1234567890abcdef",
"value": 10000000,
"gas": 2000000,
"gasPrice": 20000
}
]
}

In this example, the transactions are marked as statusequal to 1, which means successful. We can then use the obtained data to filter and verify the authenticity of these transactions.

• If you want to retrieve a list of all transactions for a specific address, use thegetAccount` endpoint instead.

By following these steps and experimenting with different approaches, you should be able to successfully filter Uniswap transactions using the Etherscan API.
