В связи с этим для себя* написал на python скрипт для прямого взаимодействия с блохчейном.
Для его работы необходимы библиотеки xrpl-py и asyncio.
pip install --user xrpl-py
pip install --user asyncio
Сам скрипт:
from xrpl.models.transactions import AMMDeposit, AMMDepositFlag, AMMWithdraw, AMMWithdrawFlag, AMMVote
from xrpl.account import get_next_valid_seq_number
from xrpl.transaction import sign_and_submit
from xrpl.clients import JsonRpcClient
from xrpl.utils import xrp_to_drops
from xrpl.wallet import Wallet
from xrpl.models.amounts import IssuedCurrencyAmount
from xrpl.models.currencies import XRP, IssuedCurrency
import random, traceback, asyncio

Вставляем код в файл (например: amm.py), вносим правку в блок SETTINGS, запускаем:
python amm.py
