Hello,
I try to capture all tranasctions sent to a Uniswap pool (eth/wbtc 0.05 0x4585FE77225b41b697C938B018E2Ac67Ac5a20c0) but i dont capture any results but i do see new transactions arrived on the Uniswap web app, i updated the code based on your example from here to my needs:
import json
import asyncio
from web3 import Web3
from websockets import connect
infura_ws_url = 'wss://mainnet.infura.io/ws/v3/XXX5e35dfa6f4d4289141b08d552XXX'
web3 = Web3(Web3.WebsocketProvider(infura_ws_url))
# Uniswap pool address
account = '0x4585FE77225b41b697C938B018E2Ac67Ac5a20c0'
async def get_event():
async with connect(infura_ws_url) as ws:
await ws.send('{"jsonrpc": "2.0", "id": 1, "method": "eth_subscribe", "params": ["newPendingTransactions"]}')
subscription_response = await ws.recv()
print(subscription_response)
while True:
try:
message = await asyncio.wait_for(ws.recv(), timeout=15)
response = json.loads(message)
txHash = response['params']['result']
# print('txHash: ' + txHash)
tx = web3.eth.get_transaction(txHash)
print('tx: ' + tx['to'].lower())
if tx['to'].lower() == account.lower():
print("Pending transaction found with the following details:")
print({
"hash": txHash,
"from": tx["from"],
"value": web3.from_wei(tx["value"], 'ether')
})
pass
except Exception as e:
print(f"Error: {e}")
if __name__ == "__main__":
loop = asyncio.get_event_loop()
while True:
loop.run_until_complete(get_event())
when executing the code:
>>> %Run -c $EDITOR_CONTENT
{"jsonrpc":"2.0","id":1,"result":"0x6727fce65300426ba5c04406d3c924a3"}

but there are no new printouts of “Pending transaction found” while in the Uniswap web app:

can you please point me out to what is it I’m missing here?
Many many thanks in advanced as this drives me nuts 
Cheers,
