Building a crypto exchanger from scratch: turnkey development
We develop cryptocurrency exchangers — from the architecture and blockchain integrations to launch and support. Your exchanger will be ready to use, not just built for a demo.

Types of cryptocurrency exchangers: choose the one that suits you best
We select the format of the exchanger to match the business goals, the audience, and the scaling requirements
Automatic exchanger
Every transaction is processed without operator involvement, through aggregator APIs. The client receives the cryptocurrency in 1-2 minutes
Manual exchanger
Requests are reviewed manually by operators. A high level of control with minimal technical costs
Semi-automatic
Small requests are handled automatically, large ones go to manual review. The optimal combination of security and speed
P2P platform
Deals are made by clients directly, and the platform acts as the guarantor. Harder to develop, but a strong scalable model
Why 70% of in-house crypto exchanger projects are never completed
Making a crypto exchanger actually work is harder than writing the code. Most companies run into problems at one of three stages: architectural preparation, integration with payment systems, or legal setup.
Security
Without a smart contract audit, an exchanger is vulnerable from day one
Blockchain integrations
Without experience, integration with blockchains takes months and often needs reworking
KYC/AML
Without verification, withdrawing fiat money is impossible
Scaling
A ready-made script cannot be scaled without rewriting it
Jurisdiction
Legal requirements block the launch unless you prepare for them
Nomium handles all of it
From building the architecture to a full turnkey launch

Buy a ready-made crypto exchanger script or build a new one from scratch?
A ready-made crypto exchanger script will let you open an exchanger faster and cheaper. However, this route is limited by a number of factors: you cannot extend the exchanger’s functionality, it is hard to scale, and you depend on the developer. Development from scratch gives full control over the architecture and security of the project. It requires more investment up front, but later saves considerable resources when you expand. With our help you will be able to choose the optimal solution — turnkey development based on proven modules gives you the maximum speed and flexibility of a ready-made script.

Why clients choose Nomium to build a crypto exchanger
Blockchain project development is our main specialization, not one service among many.
-
Experience with fintech and crypto
We have already delivered more than 200 projects in the field of cryptocurrencies: crypto exchangers, wallets, DEX platforms, smart contracts. We know every possible pain point of such products.
-
A full cycle — one contractor
Architecture, design, development, integrations, testing, launch, and support. You will not need to hire contractors at every stage.
-
Security comes first
Code audit, secure key storage, protection against front-running and flash attacks. A blockchain platform without a properly implemented security architecture is simply a vulnerability.
-
We work with real jurisdictions
We help choose a jurisdiction and open a crypto exchanger in Russia, Georgia, Kazakhstan, the UAE, and EU countries. We understand all the legal and technical consequences.
