5.5.1 Access Layer: SDK/API and Runtime Interface Specifications

Decentralized finance (DeFi) execution infrastructure can only be truly adopted by protocol developers and system builders, and form a scalable ecosystem, when it possesses usability, integrability, and auditability at the engineering level. GamePad's developer toolchain starts with standardized runtime interfaces, abstracting computing power supply, intelligent execution, and state event mechanisms into callable and composable engineering capabilities.

The SDK focuses on solidifying the integration methods of critical runtime links, including structured input of execution status and events, write-back mechanism for agent decision results and execution receipts, and unified expression of resource requests and runtime metrics. The API provides programmable access capabilities for resource application, session management and execution orchestration, enabling different protocol architectures, execution engines and service stacks to access GamePad's runtime capabilities without changing their core logic.

Through a unified interface specification, protocols and applications can describe execution load constraints, invoke inference and execution services in a consistent manner, and obtain traceable execution receipts and runtime state observation data, transforming intelligent execution from an external dependency into a fundamental capability that can be engineered and integrated.
