METHODOLOGY
Our Development & Integration Process
A proven, security-first framework for deploying and integrating persistent, on-chain rule engines into your Cosmos ecosystem application.
01
Architecture & Design Review
We analyze your application's state model and business logic to architect a CosmWasm contract suite that cleanly separates persistent data from executable rules. This ensures scalability and maintainability from day one.
1-2 weeks
Design Phase

Technical & Commercial FAQs
Common Questions on World Rule Development
Answers to the most frequent questions from CTOs and founders about building and deploying CosmWasm-based persistent world rule engines.
For a standard CosmWasm world rule engine, the typical timeline is 4-8 weeks. This includes 1-2 weeks for requirements and design, 2-4 weeks for core development and unit testing, and 1-2 weeks for security audits and final deployment. Complex multi-chain or high-frequency trading logic can extend this to 12+ weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
