overview
BUILD YOUR FOUNDATION

Custom Blockchain Development

Architect and deploy purpose-built blockchain networks for your specific business logic and performance requirements.

We build custom Layer 1 and Layer 2 solutions that move beyond generic frameworks. Our approach delivers sovereign control, optimized performance, and tailored economics for applications in DeFi, gaming, and enterprise supply chains.

  • Layer 1 Development: Build a new chain with Cosmos SDK, Substrate, or custom consensus.
  • App-Specific Rollups: Deploy zk-Rollups or Optimistic Rollups for high-throughput dApps.
  • Modular Architecture: Integrate specialized data availability layers like Celestia or EigenDA.
  • Full Lifecycle Support: From initial design and tokenomics to mainnet launch and validator onboarding.

Achieve sub-2-second finality and >10,000 TPS with a network designed for your exact use case, reducing operational costs by up to 60% versus adapting to a public chain.

PROVEN FRAMEWORK

Our Delivery Methodology

A structured, security-first approach to delivering enterprise-grade cross-chain account systems. We combine deep protocol expertise with rigorous engineering to ensure predictable, high-quality outcomes.

01

Architecture & Discovery

We begin with a deep technical assessment of your multi-chain strategy, target networks (EVM, Solana, Cosmos), and compliance requirements. This phase defines the optimal sub-account model, key management architecture, and integration scope.

Protocols Supported
02

Security-First Development

Smart contracts and relayers are built using audited libraries (OpenZeppelin, Wormhole SDK) and undergo internal peer review from day one. We implement role-based access control (RBAC), multi-sig guardians, and comprehensive event logging.

Frequently Asked Questions

Get clear answers on how we deliver secure, scalable sub-account infrastructure for institutional and enterprise clients.

A standard deployment for a multi-chain sub-account management system takes 4-6 weeks from kickoff to production. This includes architecture design, smart contract development, integration with your existing stack, security audit, and deployment to testnet/mainnet. Complex requirements like custom governance or integration with 5+ chains may extend this to 8-10 weeks. We provide a detailed project plan within the first week of engagement.
