The order was "successfully" created in the code with the transaction hash, but not found on https://explorer.binance.org/tx/

[tungleqb]

I created a new order with simple code:

import asyncio
from binancechain import HTTPClient, Wallet, Transaction, BinanceChainException, Ordertype, Side, Timeinforce, WebSocket
memo = 'xxxx xxxx xxx'
pw = 'abcd'
myChainclient = HTTPClient(testnet=False)
myWallet = Wallet.wallet_from_mnemonic(words=memo, password=pw)
Transaction = Transaction(wallet=myWallet, client=myChainclient)

async def ordproc():
new_order_txid = await Transaction.create_new_order(symbol='BNB_BUSD-DB1', side=Side.BUY,
ordertype=Ordertype.LIMIT, price= 456.2, quantity= 0.002, timeInForce=Timeinforce.GTE)
print(new_order_txid)
event_loop = asyncio.new_event_loop()
asyncio.set_event_loop(event_loop)
event_loop.run_until_complete(ordproc())

########
result: I got a response below:
CHAIN ID Binance-Chain-Tigris
[{'code': 0, 'hash': 'E0F621C2472C367544598FAF7BDE6C9B8B2A7A2FD09EA1BB8FD251D08A8731CC', 'log': '', 'ok': True}]

But I can't found the hash on real Binance Chain main netword with https://explorer.binance.org/tx/E0F621C2472C367544598FAF7BDE6C9B8B2A7A2FD09EA1BB8FD251D08A8731CC
I used mainnet, not testnet.
I checked many times after running for a few hours.

Please show me my mistake.
