I can give you a test article on how to recover the amount of token0and token1 from a Pool Uniswap V3 from JavaScript using the UNISWAP library.

Recovering the token amounts from the Uniswap pool

UNISWAP V3 offers an API for taking information about the tokens hips, including the amounts held in a basin. In this article, we will go through how to use the object uniswap.v3.

Premise

Before you start, make sure you have the following installed addictions:

Javascript

NPM Install Uniswap-JS

`

Example of code

`Javascript

const {

Uniswapv3interface,

} = requires (‘uniswap-js’);

the function async getpooltokeenamounts () {

// configure the API UNISWAP V3 instance

Constn it = New Uniswapv3intterface ({

Supplier: ‘ // replace with your project IDURA

Apikey: “your_api_key”,

});

// create a pool object for the specified pool (eg uniswap v3 test Pool)

Const pool = wait api.getpool (‘0x …’); // replace with the pool address

Try {

// get the amount of token0 and token1 in the pool

const token0amount = wait pool.getbalanceof (‘token0’);

const token1amount = wait pool.getbalanceof (‘token1’);

return {token0amount, token1amount};

} Catch (error) {

console.error (error);

Turn null;

}

}

// Example of use:

GetPoolTokeneamounts (). Then ((results) => {

IF (results) {

const {token0amount, token1amount} = results;

console.log (sum token0: $ {token0amount});

console.log (sum token1: $ {token1amount});

}

});

`

Explanation

In this example of code:

• We create a new instance of the “Uniswapv3interface” class, passing into the ID of our project Infura and the API key as arguments.

• Then we create a pool object for the specified pool (for example, Uniswap V3 Testnet Pool).

• We use the GETBALANCEOF ‘method to take over the amount of token0 and token1 in the pool.

• Finally, we return an object with the amounts taken.

Trips to troubleshoot

If you encounter problems of recovery of the token amounts using this code, here are some troubleshooting tips:

• Make sure you have replaced the localization addresses (0x ...) with your real address of the Uniswap V3 pool.

• Check that your Infra and API key ID are correct and valid.

• Check the UNISWAP documentation for any changes to the API or requirements for UNISWAP V3 use.

By following this article, you should be able to take over the amount of token0 and token1 from a Pool Uniswap V3 in Javascript. If you have any problems or have additional questions, do not hesitate to ask!
