• Incompatible Contract Calls: Make sure your Web3.py script uses the correct ABI (Application Binary Interface) and calls the appropriate functions in the target contract.

Solution: Token Swap

To swap board tokens from one address to another, follow these steps:

Step 1: Obtain the required private key

Make sure you have a valid private key for PERMIT_ADDRESS. You can do this by doing the following:

• Retrieve the private key from the contract using the eth_getRawTransaction Web3.py function.

• Alternatively, you can use your preferred method to retrieve the private key.

Step 2: Obtain transaction details

To swap board tokens, you need to create a new transaction. You can do this by doing the following:

• Retrieve the current account balance for “BRETT_ADDRESS”.

• Create a new contract instance using the Web3.py contract class.

• Set the parameters for the swap process.

Step 3: Perform the swap

Here is an example code snippet showing how to swap board tokens:

import web3





Define constants and variables
ADDRESS_PERMIT = '0x000000000022D473030F116dDEE9F6B43aC78BA3'
BRETT_ADDRESS = '...
contract address = '0x...'

Get the current balance of tokens on the board
balance = web3.eth.getBalance(BRETT_ADDRESS)

Set the parameters for the swap process
parameters = [
{'from': PERMIT_ADDRESS, 'to': BRETT_ADDRESS, 'value': 10}, 
Swap board tokens worth 10 board units
]

Create a new transaction with the Transaction class Web3.py
tx = web3.eth.getTransaction(params[0], {"chainId": 1})

Sign the transaction with your private key (replace it with your actual private key)
signedTx = tx.sign(privateKey)

Send the transaction to the Ethereum network
web3.eth.sendRawTransaction(signedTx.rawTransaction, {'gas': 40000, 'gasPrice': web3.toWei(20, 'gwei')})

Step 4: Verify the exchange

To make sure the exchange was successful, you can:
