CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect, develop, and audit custom Solidity/Rust smart contracts that form the immutable backbone of your application. Our code is built for security first, leveraging battle-tested patterns from OpenZeppelin and rigorous internal review processes.
- Custom Logic: Implement complex business rules for DeFi, NFTs, DAOs, and RWA tokenization.
- Gas Optimization: Achieve up to 40% lower transaction costs through efficient code patterns and storage design.
- Full Audit Trail: Every contract includes comprehensive documentation,
NatSpeccomments, and is pre-vetted for common vulnerabilities.
We deliver a deployable, auditable codebase in 2-4 weeks, complete with test suites covering >95% of code paths and a clear upgrade path for future iterations.

Frequently Asked Questions
Get clear answers on timelines, security, and process for your private transaction portal project.
A production-ready ZK-Rollup privacy portal with core features (deposit, shielded transfers, withdrawal) typically deploys in 6-8 weeks. Complex integrations (custom circuits, multi-asset support, fiat on/off ramps) can extend this to 10-12 weeks. We follow a phased delivery model with weekly sprints and milestone reviews.
