trongrid-extractoor 2.0.1

Extract transactions from the Trongrid API.

Usage

Command Line

The extract_tron_events script will extract events from Trongrid. Run extract_tron_events --help to see the command line options. --since and --until arguments should be specified in ISO8601 time format.

Examples:

# By address
extract_tron_events --until 2023-06-26T16:07:39+00:00 -t TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t

# For symbol (only works for some preconfigured tokens)
extract_tron_events --since 2023-06-26T16:07:39+00:00 -t USDT

# All events (not just 'Transfer')
extract_tron_events -t wstUSDT --e None

# Resume an extraction you already started
extract_tron_events --resume-csv events_HT_TDyvndWuvX5xTBwHPYJi7J3Yq8pq8yh62h_written_2023-07-20T16.50.59__UP_THROUGH_2023-07-20.csv

As Package

from trongrid_extractoor.api import Api

Api().contract_events('TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t')

Arguments for contract_events() can be found here.

contract_events() hits the contracts/[CONTRACT_ADDRESS]/events endpoint and can pull all transfers for a given contract by filtering for event_name=Transfer. Other endpoints like contracts/[CONTRACT_ADDRESS]/transactions don't seem to really work.

Trongrid Documentation, Quirks, Etc.

UPDATE: cirac July 2023 Trongrid appears to have fixed this issue and the next URL will actually give you more than 5 pages.

When you make an API request to TronGrid they return you a page of results. If there are more than the page size (200 here) then the response includes a next key that has a URL you can hit to get the next page. Sounds convenient, right? Except it doesn't work. After 5 pages TronGrid will tell you your timespan is too big and please try again. This package is written to go around this "quirk" by backing up the max_timestamp parameter when it can't page any more.

TODO

1. Walk forward not backward
2. Weird that this yielded dupes on the first page:

   {request_params.py:29} INFO - Request URL: https://api.trongrid.io/v1/contracts/TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t/events

3. USDT looks incomplete here as 9pm was the last time:

   WARNING - 0 txns found. We seem to be stuck at 2020-07-09T21:04:24+00:00.

4. USDD around this time should be double checked:
