# Safe Transaction/Message Hashes Calculator #
##############################################
# This function orchestrates the entire process of calculating the Safe transaction/message hashes:
# 1. Parses command-line arguments (`help`, `version`, `list-networks`, `network`, `address`, `nonce`,
# `nested-safe-address`, `nested-safe-nonce`, `message`, `interactive`).
# 2. Validates that all required parameters are provided.
# 3. Retrieves the API URL and chain ID for the specified network.
# 4. Constructs the API endpoint URL.
# 5. If a message file is provided:
# - Validates that no interactive mode is specified (as it's not applicable for off-chain message hashes).
# - Validates that no `nonce` or `nested-safe-nonce` is specified (as it's not applicable for off-chain message hashes).
# - Calls `calculate_offchain_message_hashes` to compute and display the message hashes.
# - If a nested Safe address is provided, invokes the `calculate_nested_safe_offchain_message_hashes` function with the nested
# parameter values and displays the resulting hashes.
# 6. If a `nonce` is provided:
# - Fetches the transaction data from the Safe transaction service API.
# - Extracts the relevant transaction details from the API response.
# - If the interactive mode is specified, overrides the desired parameter values.
# - Warns the user if the transaction includes an untrusted delegate call.
# - Checks for a potential gas token attack.
# - Calls the `calculate_hashes` function to compute and display the results.
# - If nested Safe parameters are provided, invokes the `calculate_nested_safe_hashes` function with the approval transaction
# data and displays the resulting hashes.

Interactive mode is enabled. You will be prompted to enter values for parameters such as \`version\`, \`to\`, \`value\`, and others.
${RED}If it's not already obvious: This is YOLO mode – BE VERY CAREFUL!${RESET}
${YELLOW}IMPORTANT:
- Leaving a parameter empty will use the value retrieved from the Safe transaction service API, displayed as the "default value".
If the value is unavailable (e.g. if the API endpoint is down), it will default to zero.
- If multiple transactions share the same nonce, the first transaction in the array will be selected to provide the default values.
- No warnings will be shown if multiple transactions share the same nonce. It's recommended to first run a validation without interactive mode enabled!
- Some parameters (e.g., \`version\`, \`to\`, \`operation\`) enforce valid options, but not all inputs are strictly validated.
Please double-check your entries before proceeding.${RESET}
