overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by experts for DeFi, NFTs, and enterprise applications.

We architect and deploy custom smart contracts that form the foundation of your Web3 product. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.

Custom Logic: Tailored Solidity/Rust contracts for DeFi protocols, NFT marketplaces, DAOs, and enterprise use cases.
Security Audits: Internal review against common vulnerabilities before third-party audits, using tools like Slither and MythX.
Gas Efficiency: Optimized code to minimize transaction costs, critical for user adoption and protocol sustainability.

We deliver battle-tested contracts with a focus on mainnet security and long-term maintainability.

Our team handles the full lifecycle:

Design & Specification: Collaborative sessions to define requirements and architecture.
Development & Testing: Implementation with unit/integration tests using Hardhat or Foundry.
Deployment & Verification: Secure deployment to testnet/mainnet and source code verification on block explorers.
Post-Launch Support: Monitoring, upgrade planning, and incident response.

BUILT FOR PRODUCTION

Core Architecture of Your Randomness Beacon

Our verifiable randomness beacons are engineered for enterprise-grade security, cross-chain interoperability, and predictable performance. We deliver the foundational infrastructure for your Web3 applications.

Verifiable Randomness Engine

Cryptographically secure randomness generation using VRF (Verifiable Random Function) or commit-reveal schemes, with on-chain proofs for public verification. Ensures fair and tamper-proof outcomes for your dApps.

Cryptographic Proof

On-Chain Verification

FIPS 140-2

Security Standards

Cross-Chain Oracle Network

Decentralized oracle nodes deliver randomness to any EVM or non-EVM chain (Ethereum, Polygon, Solana, Aptos). Eliminates single points of failure and ensures high availability.

THE INFRASTRUCTURE ADVANTAGE

Why a Dedicated Cross-Chain Beacon Beats DIY

Building a secure, verifiable randomness beacon across multiple blockchains is a complex engineering challenge. Our dedicated service eliminates the operational overhead and security risks of a custom build, delivering production-ready infrastructure from day one.

Enterprise-Grade Security & Audits

Our beacon core is built with formal verification and has undergone multiple independent audits by firms like Trail of Bits. We manage the entire security lifecycle, from key management to on-chain verification, so you don't have to.

Technical FAQs for Engineering Leads

Answers to the most common technical questions from CTOs and engineering leads evaluating a custom verifiable randomness beacon.

A complete, production-ready verifiable randomness beacon (VRB) deployment typically takes 4-6 weeks. This includes 1 week for architecture design and specification, 2-3 weeks for core smart contract and oracle node development, 1 week for internal security review and testing, and 1 week for deployment and integration support. For multi-chain deployments, add 1-2 weeks per additional target chain.
