CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Custom Tokenomics & DeFi Logic: Design and implement
ERC-20,ERC-721, and custom standards for staking, lending, and governance. - Comprehensive Security: Multi-stage audits using static analysis, formal verification, and manual review against known attack vectors.
- Production Deployment: Full lifecycle management from testnet to mainnet, including upgradeability patterns and monitoring setup.
Deliver a secure, audited, and fully functional smart contract system in 4-6 weeks, backed by a 99.9% uptime SLA for deployed contracts.

PROVEN METHODOLOGY
Our Development & Integration Process
A systematic, security-first approach to delivering production-ready virtual land ownership systems. We focus on interoperability, scalability, and seamless user onboarding.
01
Architecture & Protocol Design
We design custom ZK circuits and smart contract architecture tailored to your virtual world's economics. This includes defining the ownership model (ERC-721/1155), land attributes, and interoperability standards (OpenSea, The Graph).

Frequently Asked Questions
Get clear answers on our development process, security, and outcomes for implementing ZK-proof ownership for virtual land and metaverse assets.
A standard implementation takes 3-6 weeks from kickoff to mainnet deployment. This includes 1 week for architecture design, 2-3 weeks for core circuit and smart contract development, 1 week for integration testing, and 1 week for security review. Complex projects with custom logic or multi-chain support may extend this timeline.
