What we set out to build
A serious options workstation that did not cost institutional money, and that could compare pricing across centralised and decentralised venues in one view.
What was built
- An 82-strategy catalogue with greeks and Black-Scholes mark-to-market
- A tape backtester and a live paper desk
- Cross-venue comparison across five venues, including on-chain pricing read directly via eth_call rather than through a third-party API
- Seven management engines in the Pro tier: auto-hedge, rolls, pin and margin risk, term structure, managed exits, events and alerts
- Production-hardened live execution behind a kill switch, arm token, position caps, daily loss limits, a price collar, idempotency and an audit log
What it achieves
- 193 tests
- The live signer fails closed: without a valid arm token the desk stays in paper mode
- A demo mode that hard-disables live execution, so the hosted version cannot trade by accident
The stack
Python, FastAPI, React, web3, Deribit / OKX / Bybit / Derive / Aevo / Premia.
Common questions
How was this built?
A founder brought the idea and the domain knowledge. We brought the team. The founder funded the build with a monthly subscription, and they hold equity in the company that resulted. We label every case study, because a studio that publishes its prices and argues the other side of its own comparisons has to be equally precise about its own portfolio.
What state is it in?
In production, paper by default. We state that plainly rather than describing everything as production: several things here are deliberately gated, and the reason is usually evidence rather than a missing feature.
Can you build something like this for us?
That is the point of publishing it. The same patterns are in the catalogue at published prices, and you can scope your own version on the plain-English page without contacting us first.
Where to next
If something here is close to what you need, the same patterns are in the catalogue at published prices, or you can describe your version in plain English and get it scoped and priced without talking to anyone.
