A script for completing the second part of a slow dYdX withdrawal. I needed to create this script as there was bug in the web app preventing me from completing this step so my withdrawal was stuck.

dYdX_slow_withdraw_p2.py

import requests
from web3 import Web3
from dydx3 import constants
from dydx3 import Client


WEB_PROVIDER_URL = "https://mainnet.infura.io/v3/..."

ETHEREUM_KEY = "da..."

w3 = Web3(Web3.HTTPProvider(WEB_PROVIDER_URL))

# recover stark key

    eth_private_key=ETHEREUM_KEY,
    web3=w3,

recovery = client.eth_private.recovery(ethereum_address=ETHEREUM_ADDRESS)
stark_key = recovery.data["starkKey"]

abi = requests.get(url=abi_url).json()

# contract
contract = w3.eth.contract(address=DYDX_ADDRESS, abi=abi["abi"])

withdraw = contract.functions.withdraw(
    starkKey=int(stark_key, 16),
    assetType=DYDX_ASSET_TYPE,
)
necessary_gas = withdraw.estimateGas()
gas_eth = w3.fromWei((necessary_gas * w3.eth.gasPrice), "ether")
print(f"gas cost estimation = {gas_eth:.6f} ETH")

# create txn
transaction = withdraw.buildTransaction()
transaction.update({"from": ETHEREUM_ADDRESS})
transaction.update({"gas": necessary_gas})
transaction.update({"nonce": w3.eth.get_transaction_count(ETHEREUM_ADDRESS)})

# sign and send
signed_tx = w3.eth.account.sign_transaction(transaction, ETHEREUM_KEY)
txn_hash = w3.eth.send_raw_transaction(signed_tx.rawTransaction)
txn_receipt = w3.eth.wait_for_transaction_receipt(txn_hash)
print(txn_receipt)
