Our Development & Integration Process
A structured, security-first approach to building and deploying your private rental agreement system. We deliver production-ready code with clear milestones and guaranteed SLAs.
01
Architecture & Zero-Knowledge Design
We architect your system's privacy layer, selecting the optimal zk-SNARK or zk-STARK framework (e.g., Circom, Halo2) for your use case. This includes designing the private state model and proof generation logic.

Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific business logic. Our development process is built for production from day one, ensuring reliability at scale.
- Full lifecycle development: From initial concept and
Solidity/Rustcoding to deployment onEVM/Solanaand ongoing maintenance. - Security-first approach: All code follows
OpenZeppelinstandards and undergoes rigorous internal review before third-party audits. - Common deliverables:
ERC-20/ERC-721tokens, custom DeFi protocols, DAO governance systems, and cross-chain bridges.
We deliver battle-tested contracts with a 99.9% uptime SLA and comprehensive documentation, so your team can integrate with confidence.
Our engineers specialize in complex implementations like automated market makers (AMMs), liquidity pools, and upgradeable proxy patterns. We focus on gas efficiency to minimize user transaction costs and modular design for future extensibility.

Frequently Asked Questions
Get clear answers on development timelines, security, costs, and support for your private rental agreement platform.
A standard private rental agreement system with core features (tenant screening, rent payments, maintenance requests) takes 4-6 weeks from kickoff to mainnet deployment. Complex integrations (e.g., multi-chain escrow, advanced dispute resolution) can extend this to 8-10 weeks. We follow a phased delivery model with weekly demos.
