So you want to improve CKBunker? Sure. Here are some starting points.
It’s a python program, based on aiohttp for async http operation. The web UI is
provided using Semantic UI and Vue for model/view management. HTML pages
are constructed using Jinja templates. Data between
the browser and backend is communicated mainly via a websocket that
stays open the entire time a page is shown in the browser.
See requirements.txt for complete list, but in summary, here are the major Python packages
we are using.
stemaiohttpaiohttp-jinja2ckcc-protocolpynaclclickpendulumrequests[socks]webapp.py - Web backend
chain.py - API access for sending transactions
chrono.py - Time related stuff
conn.py - Connection to a Coldcard, somewhat async wrapping for ckcc-protocol
main.py - Startup code
persist.py - Data persistance and default settings
policy.py - Manage HSM policy details.
status.py - Live state information about the system and attached Coldcard
torsion.py - Manage Tor hidden service connection (via stem)
utils.py - My favourite type of code.
make_captcha.py - Construct the capatcha.
setup.py - Pip/Pypi glue
templates/ - Jinja HTML templates, with JS and Vue code mixed in
static/ - static CSS, JS and font resources (web)
data/ - encrypted Bunker settings saved at run time.

Looking for something to do? Here are some loose ends or ideas we haven’t been able start:
Integrate PSBT faker for testing policy.
Recovery Tool: This will provide a means for you to construct a PSBT which moves all the funds the system can find on the blockchain to a new address. Use an onion-enabled block explorer to find UTXO or maybe some other backend.
Address Generator: Use this tool to make deposit addresses for your Coldcard’s wallets.
