Frequently asked questions

Cost is driven by scope, not by system type. An audit of an existing platform or UX/UI design is a matter of weeks. An MVP of a trading terminal or a prop platform takes two to four months of team work. A full brokerage platform with integrations and a back office takes longer. We give a budget range on the first call and a firm estimate after discovery.

An audit and concept take from two weeks. The first working version usually ships in 2–4 months, depending on the number of integrations. We commit to exact dates after the design stage, once the scope is known rather than guessed.

Discovery and design are paid as a separate stage at a fixed price. Development then runs in sprints with a fixed iteration price — that lets you change priorities without renegotiating the whole contract.

You do. Source code, documentation and infrastructure configuration are handed over in full and remain your property.

Yes, a non-disclosure agreement is signed before any technical details of the project are shared. Information about clients, metrics and architecture is never published without written permission.

TSYSTEM CORP., Russian Federation. Registration details and address are listed in the About section. Finvarex is the brand of the technology arm, not a separate legal entity.

Brokers, exchanges and trading venues, prop firms, funds and asset managers, banks and fintech services, as well as professional trading desks.

Both. We join at any stage: we can design a product from scratch, or take over the development and support of a live system after auditing its code and architecture.

We work in sprints and demo every two weeks. Each stage ends with a verifiable deliverable: an estimate, an architecture diagram, a working build or a production release.

We take the product into support: monitoring, an agreed SLA, fixes and new functionality from the backlog. Alternatively, we hand the system over to your team with documentation and training.

Moscow Exchange, Bybit, Binance, MEXC, Bitget, OKX. We also connect other venues over API, along with banking and payment providers, as the project requires.

Keys and secrets are stored on the backend and never reach the client, access is segregated by role, and actions are written to an audit log. Infrastructure is deployed with monitoring, backups and load testing before release.

Keys are held in a secure backend vault, never reach the client application or the repository, and their permissions are limited to the minimum operations required.
