Exchange development

Crypto exchange development for order book and DEX builds

We build centralized order book exchanges and DEX or AMM platforms, with custody and key handling designed in writing before any code is written.

What does crypto exchange development involve?

An exchange is several systems that have to agree with each other: a matching engine, an account and balance ledger, wallet services for deposits and withdrawals, a trading interface, an admin back office and monitoring. Crypto exchange development means building and connecting all of these for your market and your users.

We start with a scoping conversation about which assets you will list, which chains you will support, who your users are and which jurisdictions you intend to serve. From that we write an architecture outline and a quote.

Centralized order book or DEX and AMM: which fits?

The two models solve different problems, so the choice should follow your product, not fashion.

  • Centralized order book: a matching engine, typically written in Go or C++ with an in-memory order book, matches limit and market orders. Balances live in your ledger. This model needs KYC integration, a custody design and operational staff.
  • DEX or AMM: smart contracts hold liquidity pools and users trade from their own wallets. We build the factory, router, staking and liquidity contracts plus the interface. There is no order book to run, but contract risk becomes the main risk.

Some teams want a hybrid, with an off-chain book and on-chain settlement. We can scope that too. For contract work in this area, see smart contract development and the EVM chains and Solana pages.

How are custody and keys handled?

For a centralized exchange, custody is the most sensitive design decision. We typically design a split between hot, warm and cold wallets, with multi-signature or MPC signing for the cold side and withdrawal limits and approvals on the hot side. Integrations with custody providers or multisig tools can be used where you prefer them.

We document who can ever move funds, under which approvals, and how keys are backed up and rotated. You review that document before we build it. We build the software and hand over the code and the accounts you pay for. We do not hold your funds and we do not operate your exchange.

These are typical ranges. Your quote depends on scope, chains, integrations and how quickly feedback arrives.

  • Turnkey DEX or AMM: typically $14,000 to $28,000, with factory, router, staking and liquidity contracts and an interface. Typical delivery is 4 to 6 weeks.
  • Enterprise exchange (CEX): typically $28,000 to $65,000, with a custom order book engine, KYC integration and cold storage design. Typical delivery is 8 to 12 weeks.

You get a written quote after scoping, and we build in milestones with a working build shared at each one. More detail is on the pricing page.

What are the limits and risks?

Running an exchange is regulated in most countries. Licensing, KYC and AML duties, sanctions screening and securities or commodities rules differ by country, and in the EU the MiCA rules may apply. We build software; we do not give legal advice, and you are responsible for the licences and compliance your market requires.

Matching engine speed is a design goal that depends on hardware and load, not a promise. Contracts that hold user funds are immutable once deployed, and a security review lowers risk without removing it.

How it works

  1. Tell us what you want to build

    A wallet, exchange, contract, bot or payment flow, and the chains involved.

  2. We scope and quote

    You get an architecture outline, a timeline and a written price range.

  3. We build in milestones

    Working builds are shared at each milestone, with a security review before launch.

Questions about crypto software agency in United States

How long does crypto exchange development take?

Typical delivery is 4 to 6 weeks for a DEX or AMM and 8 to 12 weeks for a centralized exchange, once the scope is agreed. Timelines depend on assets, chains, integrations and how quickly you review each milestone. The written quote states the timeline for your scope.

Do you provide the exchange licence or legal setup?

No. We build the software only. Whether you need a licence, which KYC and AML rules apply and where you may operate are questions for your lawyer. We can build the technical hooks for KYC providers, transaction monitoring and geo restrictions, but you decide the policy.

Can you add liquidity or market makers to my exchange?

We build the technical side: APIs and connectors that market makers and liquidity providers use, and optionally a market making bot. We do not supply liquidity, users or traffic. Liquidity and listings are a business matter for you to arrange.

Who owns the exchange code?

You do. The repository, the deployment accounts and the infrastructure you pay for belong to you. We sign an NDA on request, and we hand over documentation so another engineer can maintain the system. If you later want to move to another team, nothing in our contract stops you from doing so.

Will you review the code for security?

Yes, we include a security review before launch, covering the contracts or the wallet and withdrawal logic, as described on our audit and security review page. A review reduces risk but cannot prove a system is free of bugs, so we also suggest limits on deposits at launch and monitoring after it.
