Modulus Code Foundry
Modulus Blueprint™ and Code Foundry™ are the internal systems behind every Work Unit.
Modulus AI agents have access to millions of lines of Modulus source code, design patterns, architecture, and engineering knowledge so they build on what is proven to work in production.
The structural knowledge frontier models lack
Ask a general-purpose model to build a matching engine and it returns plausible-looking code that misses what actually matters: the order in which components come together, the failure modes, the protocol nuances, and the operational lessons that never reach public training data.
The Code Foundry carries that missing layer. Trained on Modulus's production fintech source, it encodes not just what a trading system contains, but the precise sequence and structure of how one is correctly built, including exchange, brokerage, and order management system patterns, market-data and FIX engine know-how, and risk-system design, so the work inside your Work Units holds up in the real world.
Introducing the Modulus Code Foundry
The Modulus Code Foundry is our internal build engine. It puts three decades of Modulus source code, implementation patterns, and architecture behind the AI workcells our engineers direct, so every build starts from what already works instead of a blank page.
When we develop a trading platform, an exchange, a matching engine, or a compliance workflow, our AI workcells draw on the relevant Modulus engineering rather than generating it from the LLM. All of that happens inside our workflow: your job description goes in, and verified work comes out.
This is the difference between AI that approximates financial software and AI that builds on three decades of real-world lessons.
- Trading platforms, exchanges, prediction markets, and more
- Market-data layers and matching engines from proven designs
- Compliance and surveillance workflows grounded in real regulation
- Proven implementation patterns, not generic snippets
- Architecture proven in production
- Every deliverable checked by a Modulus engineer
Modulus Code Foundry provides an unfair advantage
Modulus Blueprint & Code Foundry enhance our capabilities by providing AI with access to millions of lines of Modulus source code and trade secrets, enabling our engineers to output secure, production-ready source code up to 10x faster, more efficiently, and cost effectively than in-house development using Claude Code, Codex, Opencode, or similar.
Modulus Blueprint
Modulus Blueprint™ brings 30 years of financial infrastructure experience into the AI development process, including source code, architecture, implementation patterns, regulatory awareness, testing discipline, trade secrets, and production lessons learned by our engineers.
Modulus Code Foundry™ applies the Blueprint to active development, helping AI-assisted workflows start with stronger architecture, licensed source code, relevant components, financial-system test coverage, and human engineering review. Instead of turning prompts into disconnected code, the workflow is guided by the structure, boundaries, and operational details required for financial technology that must stand up in production.
Every engagement includes licensed source code with known provenance, documentation, applicable component licenses, patent and copyright licensing where relevant, and expert support from a team that has built capital-markets systems since 1997. The result is faster development, cleaner IP, stronger architecture, better security, and fewer surprises between prototype and production.
Security built into our AI workflow
AI-assisted development opens a new attack surface, and Modulus runs its own AI workflow accordingly: hardened against prompt injection, credential theft, tool poisoning, and privilege escalation, with access scoped to each job.
The same security discipline that has protected real trading infrastructure for more than three decades is applied to our AI workflow, so adopting AI-accelerated development does not mean accepting new risk.
What you get in every Work Unit
Code generated using generic prompts can look complete while hiding serious architecture, compliance, security, and production flaws. Every Modulus Work Unit builds on a foundation exclusive to Modulus.
Production lessons
Three decades of operational know-how encoded into every build.
Proprietary fintech source
Real components from Modulus products, not generic snippets gathered from the open web.
Implementation patterns
How exchanges, matching engines, and trading platforms are built and scaled in production.
Architecture guidance
Design decisions proven under real market load, latency, and regulation.
Human quality control
A Modulus engineer checks every deliverable before it reaches you.
Expert security
Defenses against prompt injection, credential theft, tool poisoning, and privilege escalation.
Put it to work with Work Units
Blueprint, the Code Foundry, and Modulus engineers come together in the simplest offer in fintech: send a job description, and reviewed work comes back within 24 hours.
Work Units, $399
One job in, reviewed work out. No subscription, no contract - pay only for what you need.
Enterprise Solutions
The same units at scale: entire exchanges and platforms, with pause and resume on your own timeline.
Partner Program
Free enrollment for completed, approved products. We demo and market them to the Modulus client base.
Keep it running with Production Support
The Modulus Production Support Plan puts the engineers who build and understand fintech on call for your production systems. Markets move at midnight, liquidations cascade on Sundays, and infrastructure fails on holidays. When a trading platform, exchange, prediction market, or other fintech system breaks under live load, you open an incident and a Modulus engineer gets to work within your plan's response target, around the clock or across business days depending on the coverage you choose.
Every incident gets a real diagnosis, not a ticket number: investigation, root cause analysis where the cause can be determined, guidance on mitigation and workarounds, and a written summary of findings and recommendations. Support is advisory by design, so your systems stay in your hands and your credentials stay yours. Where access is needed, it is named, least-privileged, and revocable, and your team executes the changes or expressly authorizes each one.
When a fix requires changing code or configuration, that is development work, and it is handled as a Priority Work Unit that goes to the front of the queue and starts immediately. Support finds the answer; a Priority Work Unit ships the fix. Coverage runs month to month with no setup fees, no annual contract, and no lock-in. See Production Support for plans and full details.
