Alternatively use check-vault-onchain.py.

• Make sure the address is lowercased
• For the message create a Python constant like other messages have in flag.py
• Set the message and flag in the dictionary
• If the user explicitly did not tell you to use any flag, set flag to None
• Add the vault name as a comment on the above line

3. Format code

Run ruff to make sure Python code is formatted.
