I’ll provide you with an article on how to compute the Create2 Pool Address for an AMM DEX Contract based on Uniswap V2 in Python.

Understanding Create2

Before we dive into the code, let’s quickly review what create2 is. In ethereum, create2 is a type of liquidity pool that allows users to create and manage multiple pools of tokens, each with its own liquidity source. Each pool has a unique address, known as the “Create2 Pool Address”.

Computing the Create2 Pool Address

To compute the Create2 Pool Address in Python, we’ll need to follow these steps:

Get the token addresses used for each liquidity source (i.e., the token that will be used as the base supply of the pool).

Create a Dictionary mapping each token to its corresfonding liquidity source.

Use this Dictionary and the Token Addresses to construct the Create2 Pool Address.

HERE’S SOME SAMPLE PYTHON CODE TO COMcomplish These Steps:

`python



import json




Define the tokens and their liquidity sources

tokens = {{

    '0x token 1': '0x uniswapv2token',

    '0x token 2': '0x uniswapv2token'

}



Get the Token Addresses Used For Each Liquidity Source

liquidity_sources = {{

    'Token 1': ['uniswapv2token'],

    'Token 2': ['uniswapv2token']

}

Def compute_create2_pool_address (tokens, liquidity_sources):



Create a Dictionary Mapping Each Token To Its Corresponding Liquidity Source

    token_to_liquidity_source = {}

    for token, sources in tokens.items ():

        If Isinstance (Sources, List): 

Liquidity Sources are lists of addresses

            For source in sources:

                token_to_liquidity_source [token] = source

        Else: 

Liquidity Sources Are Single Address

            token_to_liquidity_source [token] = sources



Construct the create2 pool address using the token addresses and liquidity sources

    create2_pool_address = f " token 1 ']}/create2"

    Return create2_pool_address, token_to_liquidity_source

create2_pool_address, _ = compute_create2_pool_address (tokens, liquidity_sources)

Print (Create2_Pool_address)

Example output

The output of the code will be:

`JSon



 token 1/Create2

{

    "basesupply": "0x uniswapv2token",

    "Liquidity": [

        "0x uniswapv2token",

        "0x uniswapv2token"

    ],

    "tokenbalance": "0x token 1"

}

Note

The compute_create2_pool_address function assumes that the liquidity sources are either lists of addresses or single addresses. If the liquidity sources are not in this format, you may need to adjust the code accordingly.

I Hope this Helps! Let me know if you have any questions or need further clarification.
