Как сделать swap в Web3.py от MATIC на USDC

Как сделать swap обмен между MATIC на USDC через Metamask Router, uniswap или другое. У меня есть код и он отправляет средства тестовые но в метамаске не приходит обратно. Где мне взять abi и адрес контракта от Metamask Router, uniswap или других?

Код взял из: https://ethereum.stackexchange.com/questions/138155/interact-with-swap-function-for-sushiswap-contract

Вот мой код:

import time
from web3 import Web3

class swapExample():
    def __init__(self, wallet: str, private_key: str, web3RpcUrl: str, 
        buy_amount: int, from_token: str, to_token: str, rourter_adress: str, abi: str):
        
        #Setup Wallet Informations and RPC
        #Usually we place these info in separate .env or .py or .json file.
        self.wallet = Web3.to_checksum_address(wallet) #your wallet address
        self.pk = private_key #your wallet private key
        self.rpc = web3RpcUrl #your node or use public rpc
        self.web3 = Web3(Web3.HTTPProvider(self.rpc)) #connect to web3

        #Setup Swap Value / Gas limit / Gwei
        #Change these values if you want.
        self.buy_amount = buy_amount #Ether value to spend
        self.gas = 500000 #gas limit
        self.gwei = 200  #gwei

        #Setup WETH token address (to spend) and Token address (to buy)
        #In my case I'll use WBNB to buy Safemoon token (at BSC Testnet)
        self.WETH = self.web3.to_checksum_address(from_token)
        self.token_to_buy = self.web3.to_checksum_address(to_token)

        #Setup router address (Sushiswap Router Address)
        #In my case I'll use Pancakeswap Router (at BSC Testnet)
        self.router = self.web3.to_checksum_address(rourter_adress)

        #Setup SwapExactETHforTokens ABI
        #You can get this ABI directly from Verified Contract Source Code at Etherscan
        self.abi = abi

        #Creating instance.
        #We can call contract functions with this.
        self.router_contract = self.web3.eth.contract(address=self.router, abi=self.abi)

        # #Do swap.
        # self.swap()

    #From here we are going to create Swap function.
    def swap(self):
        #building transaction with swap parameters
        #you can edit this if you want
        swap_txn = self.router_contract.functions.swapExactETHForTokens(
            0, #amountOutMin(slippage)
            [self.WETH,self.token_to_buy], #path (WETH,TOKEN)
            self.wallet, #to (your wallet)
            (int(time.time()) + 10000) #Deadline
        ).build_transaction({
            'from': self.wallet,
            'value': self.web3.to_wei(self.buy_amount, unit='ether'),

        })

        #Sign swap tx and send to blockchain

        print("Txn sent, awaiting for response.")
    
        #Await for result
        tx_result = self.web3.eth.wait_for_transaction_receipt(buy_tx) 

        # Transaction status verification
        # If status == 1: Swap success.
        if tx_result['status'] == 1: 
            print("Success! TX:", self.web3.to_hex(buy_tx))
            return True 
        else: 
            print("Error! TX:", self.web3.to_hex(buy_tx))
            return False
