Here's the contract events I want to pull from the ropsten network.

Here's how I constructed the event request

event_request =  ("https://api.etherscan.io/api?module=logs&action=getLogs"+
                 f"&fromBlock={from_block}"+
                 f"&toBlock={to_block}" +
                 f"&address{contract_address}"+
                 "&topic0=0xf63780e752c6a54a94fc52715dbc5518a3b4c3c2833d301a204226548a2a8545" +
                 f"&apikey={api}")
result = json.loads(http.request(event_request)[1].decode("utf-8"))

Which gives me valid results, but I don't see any of the transaction in the specified link. I think I'm spposed to change the topic0 value but not sure what to.

Running this (using web3.js v1.x):

const Web3 = require("web3");
console.log(Web3.utils.keccak256("Transfer(address,address,uint256)"));

Gives this:

  • So are you saying that's the value topic0 should be assigned to? – financial_physician Mar 27 at 5:52

    @financial_physician: I wrote that very explicitly as far as I can tell. – goodvibration Mar 27 at 6:04
