The Go implementation of HyperSDK provides a high-performance, customizable framework for building blockchains on the Avalanche platform. It offers developers simplicity with strong default settings while allowing in-depth customization through ‘Actions’, which are the smallest units for defining state transitions via a mutable key-value store. The framework includes performance-enhancing features like state prefetching and multi-dimensional fees. It also supports configurable ‘Services’ to extend VM functionality, including options for custom APIs and Event Notifications, enabling developers to tailor their blockchain solutions. HyperSDK currently holds alpha status, indicating that it’s in early development and not yet production-ready, with ongoing efforts to stabilize the API and complete auditing.
