The cost to build a modular blockchain platform typically starts at $30,000+ and can increase based on scalability, security layers, interoperability needs, and custom features. Businesses opting for a standard modular setup with core components and limited customization will fall on the lower end of the range, while advanced solutions with high-performance execution layers, cross-chain connectivity, governance modules, and enterprise-grade compliance can reach $250,000 to $300,000+. Choosing a reliable modular blockchain development company helps ensure optimized costs, faster deployment, and a scalable architecture tailored to future business growth.
