overview
CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers.
Every contract undergoes a rigorous security-first development lifecycle, from design review to formal verification, ensuring your protocol's foundation is unshakable.
- Security Audits: All code is reviewed against common vulnerabilities and tested with tools like Slither and Foundry.
- Gas Optimization: We minimize transaction costs through efficient bytecode and storage patterns.
- Full Documentation: Receive comprehensive NatSpec comments and user guides for seamless integration.
- Deployment & Verification: We handle mainnet deployment and Etherscan verification for immediate transparency.

Shared Oracle vs. Dedicated L3 Hub: A Technical Comparison
Evaluate the technical and operational trade-offs between using a shared oracle network and deploying a dedicated Layer 3 oracle hub for your application.
| Architecture Factor | Shared Oracle Network | Dedicated L3 Oracle Hub |
|---|---|---|
Data Sovereignty & Customization | Limited to provider's feeds and update logic | Full control over data sources, aggregation logic, and update frequency |
Latency & Finality | Subject to network congestion; finality depends on L1/L2 | Sub-second finality with L3's inherent speed; predictable performance |
Security Model | Relies on provider's validator set and slashing mechanisms | Your dedicated validator set; customizable cryptoeconomic security |
Cost Structure | Per-request fees with variable gas costs | Predictable operational cost; eliminates per-call fees for internal apps |
Time to Integrate | 1-2 weeks for API/contract wiring | 4-8 weeks for end-to-end deployment and configuration |
Uptime & Reliability SLA | Provider's SLA (typically 99.5-99.9%) | Your controlled infrastructure; enables 99.9%+ SLA |
Total Cost of Ownership (Year 1) | $10K-$50K+ in usage fees | $150K-$300K for development, deployment, and operation |
Ideal Use Case | Prototypes, MVPs, apps with common data needs | Production-grade DeFi, high-frequency trading, enterprise systems |

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our team specializes in Solidity 0.8+, Rust, and Vyper, implementing OpenZeppelin standards and formal verification patterns from day one.
- Security-First Development: Every contract undergoes multi-stage audits, including static analysis (
Slither,MythX) and manual review, before testnet deployment. - Gas Optimization: We write for efficiency, routinely achieving 20-40% gas cost reductions versus unaudited code.
- Full Lifecycle Support: From initial spec to mainnet launch and post-deployment upgrade management via transparent proxy patterns.
Deliver a secure, audited MVP in as little as 2-3 weeks, with a 99.9% uptime SLA for deployed contracts.

Frequently Asked Questions
Get clear answers about our architecture, process, and support for building custom oracle solutions.
A Layer 3 Oracle Hub is a dedicated, application-specific blockchain (appchain) built for secure, high-throughput data delivery. You need one if your DeFi, RWA, or prediction market protocol requires custom data feeds, sub-second finality, and cost predictability that general-purpose oracles can't provide. It moves oracle logic from a smart contract to its own sovereign chain, eliminating network congestion and gas wars.
