SERVICE
Custom Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and deployed on-chain.
- From Specification to Mainnet: We handle the full lifecycle—design, development, testing, and deployment—with formal verification and third-party audits.
- Protocol Expertise: We build with
Solidity,Rust (Solana), orMove (Aptos/Sui), using established patterns from OpenZeppelin and other standards. - Security-First: Every contract undergoes rigorous testing (unit, integration, fuzzing) and peer review before deployment to mitigate risks.
Deliver a secure, functional foundation for your product in weeks, not months, with a clear path to audit and mainnet launch.

AppChain vs. Smart Contract-Based Access Control
A technical comparison of access control implementation strategies, highlighting the trade-offs between on-chain smart contracts and dedicated AppChains for complex, high-performance applications.
| Feature | Smart Contract-Based | Custom AppChain |
|---|---|---|
Development Complexity | High (Gas Optimization) | High (Infra Setup) |
Time to Production | 4-8 weeks | 6-12 weeks |
Transaction Throughput | Limited by L1/L2 | 10,000+ TPS |
Gas Cost for Users | High & Variable | Predictable & Low |
Custom Logic Flexibility | Constrained by EVM | Full Sovereignty |
Upgrade & Governance | Complex Proxy Patterns | Native Chain Governance |
Security Model | Public MemPool Risks | Isolated, Private Execution |
Cross-Chain Interoperability | Requires Bridges/Oracles | Native via IBC/Custom |
Typical Use Case | Simple DApps, Tokens | Enterprise DeFi, Gaming, High-Freq Apps |
Total Cost of Ownership (Year 1) | $50K - $150K | $200K - $500K+ |
