Introduction

In the realm of decentralized exchanges (DEXs), Pancakeswap V3 and Uniswap V3 have revolutionized the way we interact with cryptocurrencies. However, with the introduction of new versions, some functions have undergone changes, leaving developers wondering about the equivalent functions. In this article, we will delve into the equivalent of the deprecated getAmountsOut function for Pancakeswap V3 and Uniswap V3.

Understanding the getAmountsOut Function

Before we dive into the equivalent functions, let's understand what getAmountsOut does. The getAmountsOut function is used to calculate the output amounts for a given input amount and a list of paths. It takes in the following parameters:

amountIn: The input amount
path: A list of tokens representing the path to be taken
deadline: The deadline for the transaction

The function returns an array of output amounts for each token in the path.

Pancakeswap V3 Equivalent

In Pancakeswap V3, the equivalent function to getAmountsOut is getAmountsOutV3. However, this function has been deprecated in favor of the getAmountsOut function from the @pancakeswap/sdk-v3 package. The new function takes in the following parameters:

amountIn: The input amount
path: A list of tokens representing the path to be taken
deadline: The deadline for the transaction
options: An object containing additional options (optional)

Here's an example of how to use the getAmountsOut function from the @pancakeswap/sdk-v3 package:

const { getAmountsOut } = require('@pancakeswap/sdk-v3');
const amountIn = 100;
const path = ['BNB', 'USDT'];
const deadline = Math.floor(Date.now() / 1000) + 60 * 20;
const options = {};
const amountsOut = await getAmountsOut(amountIn, path, deadline, options);
console.log(amountsOut);

Uniswap V3 Equivalent

In Uniswap V3, the equivalent function to getAmountsOut is getAmountsOutV3. This function takes in the following parameters:

amountIn: The input amount
path: A list of tokens representing the path to be taken
deadline: The deadline for the transaction
options: An object containing additional options (optional)

Here's an example of how to use the getAmountsOut function from the @uniswap/sdk-v3 package:

const { getAmountsOut } = require('@uniswap/sdk-v3');
const amountIn = 100;
const path = ['WETH', 'USDC'];
const deadline = Math.floor(Date.now() / 1000) + 60 * 20;
const options = {};
const amountsOut = await getAmountsOut(amountIn, path, deadline, options);
console.log(amountsOut);

Conclusion

In conclusion, the equivalent of the deprecated getAmountsOut function for Pancakeswap V3 and Uniswap V3 is getAmountsOut from the @pancakeswap/sdk-v3 and @uniswap/sdk-v3 packages, respectively. These functions take in similar parameters and return the output amounts for a given input amount and a list of paths.

Node.js Implementation

Here's an example of how to implement the getAmountsOut function in Node.js using the @pancakeswap/sdk-v3 package:

const { getAmountsOut } = require('@pancakeswap/sdk-v3');
async function getAmountsOutExample() {
const amountIn = 100;
const path = ['BNB', 'USDT'];
const deadline = Math.floor(Date.now() / 1000) + 60 * 20;
const options = {};
const amountsOut = await getAmountsOut(amountIn, path, deadline, options);
console.log(amountsOut);
}
getAmountsOutExample();
