Centralized Exchanges

A matching engine built to hold under real order-book load.

Order-book matching engines, custody, and KYC/compliance infrastructure, the operational core of a centralized exchange, built for the throughput and correctness a live order book demands under real trading volume, not a backtest.

Same vetting bar either way, whether we staff the project or fill the seat. See the rubric

Matching

An order-book matching engine built for low latency under real trading load.

Custody

Hot and cold wallet custody architected for the funds it actually has to protect.

Compliance

KYC/AML and transaction monitoring built in from day one.

Reliability

Uptime and consistency treated as production requirements, not aspirations.

What we build

What we build for centralized exchanges.

A price-time priority matching engine built for low-latency execution, tested against realistic order-book depth and burst trading volume, not a quiet demo environment.

Hot/cold wallet architecture with multi-sig and withdrawal controls sized to the actual funds at risk, the split between what's kept liquid and what's kept cold is a deliberate risk decision, not a default.

How we run it

Scoped fast. Shipped on a real timeline.

012–3 weeksArchitecture and threat modelingWe design the matching engine, custody split, and compliance architecture together, since decisions in one constrain the others.

Questions

Answered before you ask.

A CEX holds custody of user funds and matches orders off-chain in a centralized engine for speed; a DEX settles trades on-chain and never takes custody. They share some blockchain integration work, wallets, on-chain settlement of deposits and withdrawals, but the trading core is a fundamentally different system.

It's a risk decision based on your expected withdrawal volume and risk tolerance, not a fixed ratio. We model it explicitly with you rather than defaulting to an industry rule of thumb that may not fit your platform.

It varies significantly by jurisdiction and the assets you list, and the rules continue to change. We build the compliance infrastructure, KYC, AML monitoring, reporting. That regulators expect to see, but licensing itself needs legal review specific to where you plan to operate.

That's what we load-test against before launch. We build to your projected order volume and burst patterns, not a generic benchmark, and we tell you honestly where the ceiling is.

Yes. For the custody and matching systems both. We do rigorous internal review first, then recommend independent third-party audit before real customer funds are at risk.

What you're not risking

Every way out of this build is already written down.

You own it, from day one

Code, prompts, models and pipelines: all work-product IP assigns to you by contract from day one, not on final payment.

No vendor lock-in

Nothing is locked to us or to a proprietary platform you can't leave. You get the repository, the documentation, and full access.

Get started

Bring us the order-book requirements. We'll tell you what's realistic.

We'll scope the matching engine, custody split, and compliance layer honestly against the volume and jurisdictions you're actually launching in.
