Build trading systems from strategy intent, with AI agents working from explicit financial rules and engineering specifications.
LeanOS creates frameworks that bring together reusable components, architecture, specifications, and agent workflows. You define the strategy and operating constraints; the framework supplies the foundations for implementing and verifying the system.
Our first framework is Options OS, for building crypto-options trading engines.
An engine needs more than entry and exit rules. It needs to understand instruments, value positions, enforce risk limits, plan hedges, execute orders, and reconcile what actually happened.
Options OS provides reusable foundations for that work:
| What your engine needs | What the framework provides |
|---|---|
| Understand market data | Instrument normalization and market facts |
| Evaluate options | Option valuation and volatility analysis |
| Track exposure | Portfolio accounting and risk assessment |
| Manage trades | Hedge planning and order construction |
| Operate consistently | Execution, lifecycle management, and reconciliation |
| Verify behaviour | Runtime contracts, tests, and observability |
- Describe your strategy: what it trades, when it acts, and what risk it can take.
- Specify its behaviour: decision rules, sizing, hedging, execution, and operating constraints.
- Build with a coding agent: use framework components and agent skills to implement the engine.
- Verify the result: check financial rules, system behaviour, and runtime evidence.
This supports engines for short and long volatility, skew and calendar trading, surface relative value, and options market making.
- Traders: turn strategy knowledge into explicit rules and an operating engine.
- Engineers: build on reusable financial components with clear boundaries.
- Builders using coding agents: give the agent defined financial meaning, implementation workflows, and verification requirements.
Options OS is a private, licensed framework.
- Strategy implementation: specify and implement your trading strategy.
- Full trading-platform delivery: build the surrounding data, execution, risk, and operational systems.
