Other resources than Etherscan:
- Coingecko --> we can create an api and request info
- Infura: https://infura.io/ --> they have free tier with up to 100 k requests/day To use Infura with python, this is an example of code to use in python:
from web3 import Web3
w3 = Web3(Web3.HTTPProvider(projectID)) receipt=w3.eth.get_transaction_receipt(trHash)
-- Once you get the receipt, you need to get the DEX smart contract ABI -- -- ABI basically tells you how does which function look like when you see it in logs --
