Frequently Asked Questions on Cosmos SDK AppChain Integration
Clear answers to common questions from CTOs and founders evaluating dedicated blockchain development.
A standard, production-ready Cosmos SDK AppChain with core modules (staking, governance, IBC) typically deploys in 4-6 weeks from kickoff. For more complex ecosystems with custom modules (e.g., DeFi primitives, NFT marketplaces), timelines range from 8-12 weeks. We offer fixed-price scoping for standard builds, with typical project costs between $50,000 and $250,000, depending on complexity and required custom logic. All quotes include architecture, development, testing, and a 90-day post-launch support window.
