auto swap bot for testnet kroma The provided code is a Python script that interacts with the Ethereum blockchain, specifically the Binance Smart Chain (BSC) in this case, to wrap ETH to WETH (Wrapped Ethereum) using a smart contract.
Here's how you can use and understand the code:
Install Required Packages: Ensure you have the necessary Python packages installed. You can install them using pip:
bash Copy code pip install web3 python-dotenv Set Up the Script: Save the provided code into a Python file, for example, wrap_eth_to_weth.py.
Environment Variables: Set up a .env file in the same directory as the script and add the following line:
makefile Copy code MNEMONIC=your_mnemonic_here Replace your_mnemonic_here with your actual Ethereum wallet mnemonic.
Contract and Account Configuration: Replace the empty strings in router_address and weth_address with the actual smart contract addresses you want to interact with.
Run the Script: Execute the script using Python:
bash Copy code python wrap_eth_to_weth.py The script will attempt to wrap a specified amount of ETH to WETH through a series of transactions.
Explanation of the Code:
The code initializes connections to the Ethereum blockchain using Web3. It defines a function to calculate the ETH amount for each transaction. The wrap_eth_to_weth_batch function wraps ETH to WETH by interacting with the specified smart contract. A loop runs a defined number of transactions and applies a delay between each transaction. The script handles errors and retries transactions for robustness. Please note that this script is interacting with the Binance Smart Chain (BSC) using Ethereum-compatible methods, and the smart contract addresses and logic may need to be adjusted based on the specific contracts you intend to use on the Binance Smart Chain.
