I made a function that sells a token in the BSC smartchain. However, I want to receive it in BNB directly instead of wBNB. How can I unwrap the wBNB I receive?
def sell_drdc(wallet_address, token_address, wallet_no): if not is_approved(token_address): approve(wallet_address, private_key) erc20 = web3.eth.contract(token_address, abi=erc20Abi) token_value = erc20.functions.balanceOf(wallet_address).call() if token_value != 0: pancakeswap2_txn = router.functions.swapExactTokensForTokensSupportingFeeOnTransferTokens (token_value, 0, [DRDC_Address, wbnb_contract], wallet_address, (int(time()) + 900)).buildTransaction({ 'from': wallet_address, 'nonce': web3.eth.get_transaction_count(wallet_address), }) signed_txn = web3.eth.account.sign_transaction(pancakeswap2_txn, private_key=private_key) try: tx_token = web3.eth.send_raw_transaction(signed_txn.rawTransaction) web3.eth.waitForTransactionReceipt(tx_token, timeout=900) display_success() # Just function that sends success message update_text() except ValueError: display_error() # Just a function that sends the error except UnboundLocalError: sell_drdc(wallet_address, token_address, wallet_no) # Attempts to repeat if something goes wrong

I managed to see what’s wrong, It should be
swapExactTokensForETHSupportingFeeOnTransferTokens
