The cost of developing an STO (Security Token Offering) platform typically ranges widely depending on various factors such as features, security requirements, and regulatory compliance. Basic STO platforms may start around $50,000 to $100,000, covering essential functionalities like token issuance, investor management, and compliance tools. More complex platforms with advanced security measures, customizable smart contracts, legal support, and additional features can escalate costs significantly, potentially reaching several hundred thousand dollars. Factors such as jurisdiction-specific legal requirements and integration with blockchain networks also impact development expenses. Overall, precise cost estimates should be tailored based on specific project needs and regulatory considerations.
