I was just trying to create something which will listen to buy(pancakeswap) events of a specific token like SafeMoon & notify me when someone buys it on pancakeswap.
My progress so far. The Way I Am Doing Now Is Finding Pancakeswap Pair Address Of A Token And Listen For Its Swap Events
pair_address = '0xBc9d0929c5a1D21BbAaB8826c0a6a78e096702A4' #Pair Address Of ORAKLER/WBNB On Pancakeswap
contract = web3.eth.contract(address=web3.toChecksumAddress(pair_address), abi=helper.getTokenAbi(pair_address))
def handle_event(event):
result = Web3.toJSON(event)
main_base = json.loads(result)
txn_hash = main_base['transactionHash']
print(result)
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.Swap.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()
In the above code, I am listing for Swap Event Of A Smart Contract And The Output I Am Getting Is
{"args": {"sender": "0x10ED43C718714eb63d5aA57B78B54704E256024E", "to": "0x4C7369b0615125481E2D6Fcd39e4d8c70DB2e830", "amount0In": 0, "amount1In": 4957805606627501, "amount0Out": 200000000000000000, "amount1Out": 0}, "event": "Swap", "logIndex": 339, "transactionIndex": 102, "transactionHash": "0x694f61f705d2fa49d6b16f9d56902f6e4b50c88e9d3adb4ab6fbea6632b0eb1b", "address": "0xBc9d0929c5a1D21BbAaB8826c0a6a78e096702A4", "blockHash": "0x6aedadf8d3618a1d21a48890d7bcfd9968df575a1a56323830f5dd242c79cdd3", "blockNumber": 14269884}
It contains Swap Event Parameter And They Look Like That
Swap (
index_topic_1 address sender,
uint256 amount0In,
uint256 amount1In,
uint256 amount0Out,
uint256 amount1Out,
index_topic_2 address to
)
I am just confused about how to determine if it's a sold ORAKLER or Just bought & if he did buy how much money In BNB did he spend.
If anyone knows any other solution to do it or anything wrong I am doing here please tell me
