you can try this code:

from moralis import evm_api
import json

api_key = "API_KEY_HERE"
params = {
    "address": "0xc35DADB65012eC5796536bD9864eD8773aBc74C4",
    "topic": "0x0d3648bd0f6ba80134a33ba9275ac585d9d315f0ad8355cddefde31afa28d0e9",
    "chain": "arbitrum",
    "limit": 1
}
body = '{"anonymous":false,"inputs":[{"indexed":true,"internalType":"address","name":"from","type":"address"},{"indexed":true,"internalType":"address","name":"to","type":"address"},{"indexed":false,"internalType":"uint256","name":"amount","type":"uint256"}],"name":"Transfer","type":"event"}'
body = json.loads(body)

result = evm_api.events.get_contract_events(
    api_key=api_key,
    params=params,
    body=body,
)

print(json.dumps(result, indent=4))

=>

you can also use streams API for even syncs:

it worked thank you very much but I can’t pull resulting pair address. Can you help me on how to pull the pair address?

#6

can you give an exact example? what pair address you want to extract from that transaction?
