Secure DBCommon questions
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.
Exchange builds run $30k–$100k+ fixed scope depending on matching-engine requirements, custody architecture, and compliance depth (KYC/AML, audit trails). We agree scope and price up front — and build to pass security certification.
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.
