Security can also have a major effect on the budget. If your application handles tokens, payments, or other digital assets, vulnerabilities in the underlying contracts can create serious risks. Therefore, testing, code review, vulnerability assessment, and security auditing may become important parts of the project.

A basic application could fall within the $20,000–$50,000 range, while a complex platform may cost $100,000–$250,000+.

The actual estimate depends on the blockchain, number of contracts, application complexity, integrations, user experience, security requirements, and development model.

Before requesting quotations, prepare a clear product specification covering the main user journeys and required features. This helps development teams understand the technical scope and provide a more accurate estimate.
