I can provide you with an article about how to recover the quantity of token0 ‘and Token1' from a Pool V3 Uniswap in JavaScript using the Uniswap library.
Recovery of token amounts from the Uniswap pool
UNISWAP V3 provides an API to recover information on tokens sales, including the amounts held in a swimming pool. In this article, we are going to explain how to use the UNISWAP.V3.pool 'object to recover the quantity of token0' and token1 '' from a UNISWAP V3 swimming pool.
Prerequisite
Before you start, make sure that the following dependencies are installed:
Javascript
NPM Install Uniswap-Js
'
Code example
Javascript
Const {
Uniswapv3interface,
} = require ('uniswap-js');
Getpooltokenamounts asynchronous function () {
// Configure the API Uniswap V3 instance
Const Api = New Uniswapv3interface ({{
Supplier: ' // Replace with your Infura Project ID
Apikey: 'your_api_key',
});
// Create a swimming pool object for the specified pool (for example a pool of uniswap test tests))
Const Pool = Waits Api.getpool ('0x ...'); // replaced by the address of the swimming pool
to try {
// Get the quantity of token0 and token1 of the pool
Const Token0amount = Wait Pool.Getbalanceof ('Token0');
Const token1amount = wait for Pool.Getbalanceof ('Token1');
Return {token0amount, token1amount};
} Catch (error) {
Console.error (error);
turn null;
}
}
// Example of use:
Getpooltokenamounts (). then ((results) => {
if (results) {
Const {token0amount, token1amount} = results;
Console.log (Token0 Amount: $ {token0amount});
console.log (token1 amount: $ {token1amount});
}
});

Explanation
In this code example:
- We create a new instance of the Uniswapv3interface 'class, passing through our Infura project ID and our API key as arguments.
- We then create a pool object for the specified pool (for example a Pool Uniswap V3 Testnet).
- We use the “Getbalating” method to recover the quantity of token0 and token1 from the pool.
- Finally, we refer an object with the recovered amounts.
troubleshooting advice
If you encounter problems to recover the tokens up pits using this code, here are some troubleshooting tips:
- Make sure you have replaced the reserved space addresses (0x …
`) by your real Pool Uniswap V3 address.
- Check that your Infura project ID and your API key are correct and valid.
- Check the UNISWAP documentation for any modification of the API or the requirements for the use of the Uniswap V3.
By following this article, you should be able to recover the amount of token0 and token1 from a UNISWAP V3 pool in JavaScript. If you encounter problems or have other questions, do not hesitate to ask!
