Use, understand, and apply the model

A blockchain development SOW must include: Fixed Scope Definition (referencing the Technical Specification Document), Deliverables and Acceptance Criteria, Milestone-Based Payment (25% at signature, 25% at TSD approval, 25% at testnet deployment, 25% at mainnet deployment), Intellectual Property Ownership (client owns all custom code), Confidentiality, Warranties and Limitations, and Change Order Process. The TSD is the controlling document for project scope.
