FULL-STACK INFRASTRUCTURE
Custom Blockchain Development
Build, deploy, and scale custom blockchain networks and applications with enterprise-grade security.
- Layer 1/Layer 2 Development: Build custom chains using
Substrate,Cosmos SDK, orOP Stack. - Smart Contract Ecosystems: Deploy secure, audited contracts for
ERC-20,ERC-721, and custom logic. - Node & Validator Setup: Provision and manage high-availability nodes with 99.9% uptime SLA.
- Cross-Chain Bridges: Develop secure, trust-minimized bridges for asset and data interoperability.
We deliver a complete, audited mainnet launch—not just code. Our security-first approach includes formal verification and penetration testing before deployment.

THE FOUNDATION FOR TRUST
Why On-Chain, Provable RNG is a Business Imperative
In Web3, randomness is a critical infrastructure component, not a feature. Off-chain oracles and centralized sources introduce unacceptable risk and opacity. We deliver the provable, transparent, and tamper-proof randomness your protocol requires.

PROVEN METHODOLOGY
Our Development & Integration Process
A streamlined, security-first approach to integrate verifiable randomness into your Web3 application, from initial design to production deployment.
01
Requirement & Architecture Design
We analyze your use case (NFT minting, gaming, lotteries) to design a secure randomness architecture. We select the optimal solution: VRF integration (Chainlink, API3), commit-reveal schemes, or custom RNG contracts.

Technical & Commercial Considerations
Decentralized RNG: Key Questions for Founders
Essential questions to evaluate when integrating a production-grade, verifiably random number generator for your Web3 application.
Typical integration takes 2-4 weeks from specification to mainnet deployment. This includes designing the commit-reveal scheme, implementing the VRF (Verifiable Random Function) oracles, and conducting security reviews. For standard integrations using our pre-audited templates, deployment can be as fast as 1 week.
