I’d be happy to help you calculate the swap amount from DECA (derivative currencies) using the ‘sqrtPrice’ method for Uniswap V3 and 2:00 AM.

Calculating Swap Amount: A Step-by-Step Guide

The ‘sqrtPrice’ function is a key part of Uniswap’s liquidity pool. It calculates the swap amount for a given input token (‘inputToken’) based on the output token (‘outputToken’, which can be derived from a DEX), the price of the output token, and the total liquidity of the pool.

To calculate the swap-out amount using sqrtPrice' with Uniswap V3, follow these steps:

• priceOfOutputToken: The price of the output token (outputToken) at the time of the swap.

• poolLiquidity: Total liquidity of the pool, represented by thetotalAmountOutparameter in Uniswap V3.

ThesqrtPricefunction can be used to calculate the swap amount as follows:

def calculate_swap_out(amount_in, output_token_price, total_liquidity):





Calculate the swap-out amount using sqrtPrice
swap_out_amount = (amount_in / output_token_price) * total_liquidity
returned_swap_out_amount

Example usage:
input_token_price = 1,000 
in wei
output_token_price = 500 
in wei
total_liquidity_v3 = 10e18 
in wei
sum_in = 1e15 
in wei (example value)
swap_out_amount = calculate swap_out(amount_in, output_token_price, total_liquidity_v3)
print(f"The swapped amount is {swap_out_amount}wei")

You can use a library such as OpenZeppelin's ERC20Token’ to derive the output token from a DEX, or you can use your own logic to calculate the output token.

For example, if you have a DEX that provides the following parameters:

| Parameter | Description |

| — | — |

| baseToken | The input token used for the derivation. |

| numTokens | The number of tokens in each group. |

| priceOfBaseToken | The price of the input token at the time of derivation. |

You can calculate the output token like this:

def derive_output_token(base_token, num_tokens, base_token_price):

Calculate the output token using the OpenZeppelin ERC20Token library
from openzeppelinrc import ERC20Token
output_token = ERC20Token(
base_token,
num_tokens,
_base_token_price * (number_of_tokens - 1)
)
return_token

Example usage:
base_token_price = 10e6 
in wei
tokens_number = 1000 
in wei
price_of_base_token_v2 = 20e3 
in wei
output_token = derived_output_token(base_token_price, token_number, base_price_of_token_v2)
print(f"Output token is: {output_token.name}")

4. Calculate swap-out using sqrtPrice using Uniswap V2 and AMM

You can use a similar approach as above to calculate the swap amount for Uniswap V2 and AMM.
