from web3 import Web3, HTTPProvider
from eth_abi import encode
import json
import time
import config
from eth_account import Account
from eth_account.messages import encode_structured_data

account = Account.from_key(pvkey)
nonce = web3.eth.get_transaction_count(account.address)
deadline = int(time.time()) + 1000000
fdi = bytes(0x0f)
salt = bytes(0x0000000000000000000000000000000000000000000000000000000000000000)
