Python 如何为BTC汇集成对创建的事件？

我有一个获取新eth对的循环代码。我使用了web3.py库。它看起来像：

import json
import time
import pymysql
import asyncio
from web3 import Web3

infura_url = "https://mainnet.infura.io/v3/..."
web3 = Web3(Web3.HTTPProvider(infura_url))

uniswap_factory = '0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f'
uniswap_factory_abi = json.loads('[{"inputs":...]')

contract = web3.eth.contract(address=uniswap_factory, abi=uniswap_factory_abi)

def handle_event(event):
    json_object = json.loads(Web3.toJSON(event))

    token = json_object['args']['pair']
    token0 = json_object['args']['token0']
    token1 = json_object['args']['token1']

    abi = '[{"constant":true, ...]'

    Contract = web3.eth.contract(address=json_object['args']['token0'], abi=abi)

    if Contract.functions.name().call() == "Wrapped Ether":
        Contract = web3.eth.contract(address=json_object['args']['token1'], abi=abi)

    print(token)


async def log_loop(event_filter, poll_interval):
    while True:
        for PairCreated in event_filter.get_new_entries():
            handle_event(PairCreated)
        await asyncio.sleep(poll_interval)



def main():
    event_filter = contract.events.PairCreated.createFilter(fromBlock='latest')

    loop = asyncio.get_event_loop()
    try:
        loop.run_until_complete(
            asyncio.gather(
                log_loop(event_filter, 2)))
    finally:
        loop.close()


if __name__ == "__main__":
    main()

我可以使用此代码获取最新的对，并将其添加到mysql数据库中。在这里，它工作得很完美，但现在我只想用btc做同样的事情。是否有任何python库可供使用
