overview
FULL-STACK ENGINEERING

Custom Blockchain Development

Build production-ready, scalable blockchain networks and applications tailored to your business logic.

We architect and deploy custom blockchains, sidechains, and application-specific rollups. Our full-cycle development delivers secure, high-performance infrastructure from concept to mainnet, including consensus design, node orchestration, and RPC services.

  • Layer 1 & 2 Solutions: Build sovereign chains with Substrate, Cosmos SDK, or custom EVM rollups with Arbitrum Nitro/OP Stack.
  • Smart Contract Core: Develop and audit core protocol logic in Solidity, Rust (Sealevel), or Move.
  • Node Infrastructure: Managed validator sets, indexers, and >99.9% uptime RPC endpoints.
  • Cross-Chain Integration: Secure bridges and messaging layers using Wormhole, LayerZero, or Hyperlane.

We deliver a complete, audited network in 8-12 weeks, not just a proof-of-concept. Our battle-tested frameworks reduce time-to-market by 60% versus in-house builds.

Frequently Asked Questions

Get clear answers on how our Cairo-based zk-Scoring System integrates, performs, and scales for your StarkNet application.

A zk-Scoring System is an on-chain reputation and risk assessment layer built with zero-knowledge proofs. On StarkNet, it allows you to evaluate user wallets or entities based on on-chain history (transactions, holdings, DeFi interactions) without exposing the underlying data. You need it to build sophisticated applications like under-collateralized lending, curated governance, or advanced airdrop distributions that require trust and reputation without sacrificing user privacy or scalability.
