The NEM2 Software Development Kit is the primary software development tool to create NEM2 components, such as additional tools, libraries or applications. Almost all, if not all, components should use NEM2-SDK instead of raw API.

The new SDK enables developers to focus on their product rather than on the NEM2 Blockchain specific API details due to its higher abstraction.

The best way to learn to use the SDKs is through guides.
