What we build for you
Specific deliverables we engineer for this sector.
Trading platforms & order books
Low-latency matching engines with real-time order books, WebSocket feeds and reliable settlement.
Wallet & custody infrastructure
Multi-signature wallets and hardware-backed key management with defence-in-depth security.
On-chain analytics
Pipelines that turn raw blockchain data into actionable signals — positions, flows, risk exposure.
DeFi & regulatory reporting
Smart contract integrations, portfolio accounting and regulatory reporting across jurisdictions.
The challenges
- Extreme latency and throughput demands during volatile markets.
- Custody and key management with no room for error.
- Evolving regulation across multiple jurisdictions.
How we help
- Low-latency engines and matching systems built for peak load.
- Hardened wallet and key-management with defence in depth.
- Configurable compliance and reporting across jurisdictions.
How we deliver
Our battle-tested approach, adapted to this industry's constraints.
- 01
Regulatory & use-case scoping
We identify applicable regimes (MiCA, VASP) and design compliance into the product before protocol selection.
- 02
Protocol & architecture design
We select chains, consensus mechanisms and off-chain components, and design for worst-case throughput.
- 03
Security-hardened build
Smart contract audits, key management ceremonies, multi-sig thresholds and HSM integration.
- 04
Live monitoring & incident response
24/7 on-chain monitoring, circuit breakers and incident runbooks from day one on mainnet.
