Crypto & Stock Exchange Development

A full exchange build: order matching, wallet custody, KYC and compliance hooks, and the security review that handling real value requires, engineered as one system rather than bolted-together parts.

An exchange is financial infrastructure, not a website

An exchange has to match orders correctly under load, custody funds without a single point of failure, and satisfy the compliance checks your jurisdiction actually requires, all while staying fast enough that traders do not notice the engineering underneath. Getting any one of those wrong is not a bug report, it is lost funds or a regulator paying attention. This is scoped and quoted individually because the real cost depends heavily on asset types, custody model, and compliance scope, not something a standard checklist can price sensibly.

What we build

  • An order-matching engine sized for your expected trading volume
  • A custody model for wallets, whether that is hot/cold wallet separation, multi-signature, or a custodial partner integration
  • KYC and AML hooks wired into onboarding and monitoring, built to the compliance scope you specify
  • Fiat and crypto on-ramp and off-ramp integrations
  • An admin dashboard for operations: order oversight, user management, and incident response
  • A security review and third-party audit before any real funds touch the system

How the build runs

  1. 1

    Scope and compliance mapping

    1-2 weeks

    We map the asset types, jurisdictions, and compliance requirements before any architecture decisions are made.

  2. 2

    Architecture and custody model

    1-2 weeks

    The matching engine, custody approach, and data model are designed and reviewed before code starts.

  3. 3

    Core build

    6-16 weeks

    The matching engine, wallet layer, and trading interface are built in stages, each one testable independently.

  4. 4

    Security review and audit

    2-4 weeks

    Internal review followed by a third-party audit on every contract and service that touches funds.

  5. 5

    Staged rollout

    2-4 weeks

    Launch starts with limited volume and a small asset set, expanding as the system proves itself in production.

How we work

How we deliver

  1. 1

    Discovery & Scoping

    1-3 days

    We start by understanding the actual problem and your existing systems, not just the brief.

  2. 2

    Architecture & Plan

    2-4 days

    We map the technical approach and integration points before any code gets written.

  3. 3

    Build

    1-8 weeks, scoped to your project

    AI-augmented development that moves fast without skipping review.

  4. 4

    Test & Launch

    2-3 days

    Real testing against real scenarios before it touches a live user.

  5. 5

    Tune & Support

    Ongoing

    We monitor and refine in the weeks after launch. This isn't a handoff and disappear.

What you get out of it

  • An exchange built for the compliance and custody model your business actually needs
  • A matching engine tested under the load you expect, not just a demo
  • An audited system before real funds are at risk
  • An operations team that can actually run and monitor what was built

Questions we get about this

A focused exchange with a defined asset list and compliance scope typically runs three to six months from kickoff to audited launch. Wider scope, more asset types, or multiple jurisdictions extend that.
