Crypto Exchange Development Services
Commission us to build a centralised trading venue where your users deposit assets, place orders and withdraw. The engagement covers matching, balances, custody, compliance tooling and liquidity, built so that each part can be audited separately.

Custody split by hot and cold tiers
Deliverables
What a crypto exchange development engagement delivers.
02Delivered
Internal ledger
Double-entry accounting for every deposit, trade, fee and withdrawal, reconciled continuously against on-chain balances and custody statements.
03Delivered
Custody architecture
Deposit address generation, a small hot wallet with withdrawal limits, cold or MPC-based storage for the bulk of funds, and approval workflows for moving between them.
04Delivered
Compliance integration
Hooks for your chosen KYC, sanctions screening and blockchain analytics providers, plus Travel Rule messaging where your jurisdiction requires it.
05Delivered
Trading interfaces and APIs
Web and mobile trading screens, plus REST and WebSocket APIs for market makers, with rate limits and API key scopes.
Early decisions
Technical decisions we settle early in crypto exchange development.
01Decided
Custody model
Self-custody with HSM or MPC signing, a regulated third-party custodian, or a mix. This decision affects licensing, insurance options and the size of your operations team.
02Decided
Engine design
A single-threaded, in-memory engine per market with an append-only event log is the usual starting point; sharding comes later if volume demands it.
03Decided
Liquidity strategy
Onboarding market makers through APIs, connecting to external venues for hedging, or both, and how quotes from external sources are kept from distorting your own book.
04Decided
Jurisdiction and licensing scope
Which markets you will serve and which regimes apply there shapes onboarding, reporting and product limits. Your legal advisers set this; we build to it.
05Decided
Withdrawal controls
Velocity limits, address allowlists, cooling-off periods for new addresses and manual review thresholds, balancing user experience against theft risk.
Engagement
How a crypto exchange development engagement runs.
- 01Phase 1
Operating model and compliance brief
With your compliance and legal advisers, we capture the obligations the platform must support, the providers you will use and the operational roles who will run it.
- 02Phase 2
Core ledger and engine
We build the ledger and matching engine first and test them with replayed order flow, checking that balances reconcile after every event and that replays produce identical results.
- 03Phase 3
Custody and chain connections
Deposit detection, confirmation thresholds per asset, withdrawal signing and reconciliation are added chain by chain, starting with the assets you will list at launch.
- 04Phase 4
Controlled launch
A closed beta with limited users and assets, penetration testing, surveillance rules switched on, and gradual expansion as reconciliation and support processes prove reliable.
Fit
When a custom crypto exchange is the right choice.
01Good fit
You plan to operate a regulated venue
You have or are pursuing the relevant authorisation and need a platform built around those obligations.
02Good fit
Off-the-shelf scripts fall short
You need control over the ledger, custody and risk rules that packaged exchange software does not expose.
03Good fit
Audits are expected
Proof of reserves, financial audits or regulator reviews will require traceable records from day one.
Alternatives
When we recommend something other than a custom crypto exchange.
01Consider
A ready exchange product
If speed matters more than a bespoke engine, a pre-built exchange script can be adapted to your brand and markets.
Open register02Consider
A non-custodial venue
If users should trade from their own wallets without depositing, an on-chain AMM or order book is the better design.
Open register03Consider
Users mainly store and send
When trading is a minor feature and holding assets is the main need, a wallet product fits better.
Open registerThe ledger matters more than the order book
Exchanges rarely fail because orders match slowly. They fail because balances drift from what is actually held, through double-credited deposits, race conditions on withdrawals or fees booked in the wrong place. A double-entry ledger with continuous reconciliation catches drift within minutes.
Custody is an operational discipline
Keeping most funds cold and only a small float hot limits what a breach can take. The harder part is the process: who approves a top-up from cold storage, how many signers are needed, and what happens when one of them is unreachable at a weekend.
We design those workflows with your operations staff, because they will run them long after launch.
Compliance is a set of integrations and records
Identity verification, sanctions checks, transaction monitoring and, in many places, Travel Rule data exchange are delivered by specialist providers. Our job is wiring them into onboarding, deposits and withdrawals, and keeping records that let your compliance team answer a regulator’s question quickly.
Determinism makes disputes answerable
An engine that processes an ordered log of events can be replayed to show exactly why a trade happened at a given price. That replay is invaluable for customer complaints, surveillance investigations and testing changes before release.
FAQ
Questions to resolve before the build.
01Will the platform make us compliant?
No software does that on its own. Compliance depends on your licences, policies and people. We build the tooling your obligations require, such as screening, record keeping and reporting hooks, to a specification agreed with your advisers.
02Do you provide liquidity?
No. We build the APIs and connectors that market makers and external venues use, but liquidity agreements are between you and those firms.
03Can you integrate a third-party custodian?
Yes. Many exchanges use a regulated custodian for cold storage and run only a small hot wallet themselves. We integrate their APIs and keep your ledger reconciled with their statements.
04How do you prove user balances are backed?
The ledger is built so you can produce a liability snapshot and match it against wallet holdings, which is the basis of proof-of-reserves reports. An independent firm should attest to them.
