trongrid-extractoor 4.4.2

Extract transactions from the Trongrid API.

Usage

No configuration is needed to use trongrid_extractoor either from the command line or from your own python code.

Command Line

The extract_tron_events script will extract events from Trongrid to either CSV (for Transfer events) or JSON (for all other event types). 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 all

# Resume an extraction you already started
extract_tron_events --resume-csv events_HT_TDyvndWuvX5xTBwHPYJi7J3Yq8pq8yh62h.csv

Other Helpful Command Line Tools

Convert between timestamp seconds and ISO8601 format strings:

$ epoch_ms_to_datetime 1616507145000
=> 2021-03-23T13:45:45+00:00

$ datetime_to_epoch_ms 2021-03-23T13:45:45
=> 1616507145000000

Convert between address formats:

# From hex format (starting with "0x" (eth) or "41" (tron)):
$ hex_address_to_tron 41102af1de57f7389468e22a72c529d78f2d4a5fde
=> TBShFz6ZKyEySS2vgd4s2yDsCTkQxtfqvy
hex_address_to_tron 0x102af1de57f7389468e22a72c529d78f2d4a5fde
=> TBShFz6ZKyEySS2vgd4s2yDsCTkQxtfqvy

# From base58 ("Tron format)
tron_address_to_hex TBShFz6ZKyEySS2vgd4s2yDsCTkQxtfqvy
=> 0x102af1de57f7389468e22a72c529d78f2d4a5fde

As Python Package

Event Extraction

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. Arguments for contract_events() can be found here.

from trongrid_extractoor.api import Api

api = Api()

# For when there's a reasonably small number of events you can use get_all_contract_events()
mints = api.get_all_contract_events(self, 'Mint')

# If there's a whole lot of events it's good to page through them
for events in api.contract_events('TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t', since='2022-05-05', until='2022-08-31'):
    for event in events:
        do_something_with(event)

# Get contract:
usdt = api.get_contract('TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t')

# Get account info:
tether_tronscan_account = api.get_account('TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t')

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:
