Crypto exchanges built by a team that solved custody
We build centralized exchanges with the hard parts done right — matching engine, custody wallets, KYC/AML, and audit trails. We already run custody infrastructure in production for a gold-backed token platform. Fixed scope, $30k–$100k+.

The pieces most builds get wrong
Plain list. Every one of these is a solved problem in our stack — ask and we'll walk you through it.
Proof
We already run the hardest part: custody
Custody is where most exchange projects quietly fail. Ours is in production.
Vault-wallet infrastructure
Platform-held wallets backing tokens 1:1, with reconciliation between on-chain supply and real holdings.
KYC-gated by design
Onboarding, transfer restrictions, and audit logs built to pass certification — not added after launch.
Built for real volume
Architecture designed for throughput and reliability, not a demo that breaks at the first traffic spike.
Know the number before you commit
Exchange builds run $30k–$100k+ depending on matching-engine needs, custody architecture, and compliance depth. We agree scope and price up front, and build to pass security certification the first time.
How we build
Security and compliance first, features second
An exchange is a custodian of other people's money. We build like it.
Compliance mapping
We map KYC/AML and jurisdiction requirements before architecture, with your licensed counsel.
Custody architecture
Hot/cold split, key management, and reconciliation designed before a single trade flows.
Security hardening
Threat modeling, testing, and VAPT-grade review — the standard behind our live custody platform.
Launch & monitor
Deployed with monitoring, audit trails, and the operational tooling your team runs it with.

CEX development at Essen Software is building matching engines, order management, custody, and surveillance systems—with sub-100μs latency, circuit breakers, and compliance-ready architecture for regulated markets.
We implement circuit breakers, real-time margin liquidators, and dynamic risk limits at the engine level so extreme volatility does not compromise system or user funds.
We offer both: self-hosted MPC modules and integrations with Tier-1 custodians (e.g. Fireblocks, BitGo). You choose based on jurisdiction and control requirements.

Yes — we built the custody-wallet infrastructure for a 1:1 gold-backed token platform: platform-held vault wallets backing every token in circulation, with auditable reconciliation between holdings and on-chain supply. Custody, KYC gating, and audit logs are solved problems in our stack. Related: RWA tokenization.
