Privacy-First AppChain Development

We build dedicated, application-specific blockchain rollups (AppChains) with privacy as a foundational primitive, optimized for your dApp's performance and confidentiality needs.

overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production by blockchain specialists.

We architect and deploy custom, gas-optimized smart contracts on EVM and Solana that form the secure backbone of your application. Our development process is built for enterprise-grade security and scalability from day one.

  • Production-Ready Code: Built with Solidity 0.8+ and Rust, following OpenZeppelin standards and secure design patterns.
  • Full Audit Cycle: Includes comprehensive unit testing, formal verification, and preparation for third-party audits from firms like CertiK or Quantstamp.
  • Deployment & Management: We handle mainnet deployment, upgradeability patterns (TransparentProxy/UUPS), and provide 24/7 monitoring.

Deliver a secure, auditable foundation that reduces time-to-market and mitigates critical financial risk.

PREDICTABLE, TRANSPARENT, AND SECURE

Our 4-Phase Delivery Process

We deliver production-ready, privacy-first AppChains through a structured, milestone-driven approach. Each phase has clear deliverables, technical reviews, and client sign-offs, ensuring alignment, mitigating risk, and guaranteeing a successful launch.

01

Phase 1: Architecture & Design

We define your AppChain's core architecture, including consensus mechanism (e.g., Tendermint, Geth fork), privacy layer integration (ZKPs, TEEs), and tokenomics. This phase establishes the technical blueprint and security model.

Deliverables: Technical Specification Document, Network Architecture Diagram, Initial Threat Model.

2-3 weeks
Typical Duration
3+
Design Reviews
02

Phase 2: Core Development & Privacy Integration

Our engineers build the chain's core logic, custom modules, and integrate chosen privacy primitives (e.g., Aztec, zkSync's ZK Stack). All code follows OpenZeppelin standards and is developed with comprehensive unit/integration tests.

Deliverables: Deployable Chain Codebase, Privacy Module SDK, Initial Testnet Deployment.

Phase 3: Security Audit & Hardening

The codebase undergoes rigorous internal review followed by an external audit from a top-tier firm (e.g., Trail of Bits, Quantstamp). Vulnerabilities are remediated, and the chain is stress-tested under mainnet-like conditions.

Deliverables: Final Audit Report, Remediation Log, Performance Benchmark Report.

Phase 4: Deployment & DevOps

We deploy the validated AppChain to your chosen infrastructure (cloud, bare metal) with automated CI/CD, monitoring (Prometheus/Grafana), and alerting. We provide full documentation and handover operational runbooks to your team.

Deliverables: Live Mainnet, DevOps Pipeline, Monitoring Dashboard, Operational Runbooks.

Frequently Asked Questions

Get clear answers on timelines, security, costs, and our development process for building confidential blockchain applications.

From initial design to mainnet launch, a standard deployment takes 4-8 weeks. This includes 1-2 weeks for architecture and privacy model design, 2-4 weeks for core development and integration of privacy modules (like zk-SNARKs or secure enclaves), and 1-2 weeks for testing, security audit review, and deployment. Complex protocols with custom privacy logic can extend to 12+ weeks. We provide a detailed project plan with milestones during the discovery phase.
