|
+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 --
