The old audit trail; the "comptroller" was simply json appended to file. The json is now converted to SQL columns and the data is searchable via traditional queries:

Additionally,

• a colorized terminal based database viewer shows the latest transactions
• a test chain "XYZ" allows for more simulations without external api connectivity
• greatly improved README.md describes the gateway in detail and provides images and video
• a process watchdog ensures all subprocesses are live, provides alerts if not, and shuts down cleanly
• foreign chain signing SDK's for xrp, btc, ltc, and eos have been frozen and embedded to limit future SDK conflicts
• a flowchart of the app was added for clarity
• the entire app was exposed to gpt engine for:
  make minor revisions for clarity, code quality, maintainability, add inline comments where pertinent, improve docstrings, add typehints, do not change function, do not delete any comments but do improve grammar and spelling
