Blockzen

Engineering

We build production blockchain systems, and we operate them.

A single senior team designs, ships and runs production blockchain infrastructure for the protocols and teams we work with, and for our own use. The same stack that has to hold up in production is the stack we build for clients.

Backend & data infrastructure

High-availability services that keep state consistent and never lose a transaction.

  • Shared-database architecture for side-by-side deployments
  • Oracle price-history (OHLC) services and APIs
  • Automated recovery for expired cross-chain swaps
  • Automated liquidation and keeper jobs
  • Operations dashboards with search, audit logs and reporting

Cross-chain settlement systems

Routing and coordination software for cross-chain transaction settlement.

  • Message routing and path selection across 20+ networks
  • Configurable fee logic and request validation
  • Data freshness guards and multi-RPC failover
  • Operational dashboards for latency, success rates and route analytics

SDKs & developer tooling

Integration layers that reach many networks through one interface.

  • Cross-chain SDKs (swaps, money market, bridge)
  • Edge API gateway with staged, CI-enforced releases
  • Integration guides and developer documentation

Frontend & product

Fast, secure web products and partner-facing surfaces.

  • Web platforms and partner / asset directories
  • Performance and security hardening (CSP, Trusted Types)
  • Single-source-of-truth data feeds for public metrics

Infrastructure & DevOps

Multi-cloud operations built to run around the clock.

  • Multi-cloud deployment (AWS, Hetzner) with Prometheus monitoring
  • 24/7 reliability, failover and health alerting
  • Staged release pipelines and cost optimization

Product design

A lean design system and clean, on-brand surfaces.

  • Design systems (color, type, spacing primitives)
  • Brand kits and marketing pages
  • Web and product UI

Engagements are fixed-scope development and licensing. To talk about a build: contact@blockzen.io
