Overview

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.

Warning

The SDKs methods could change until it reaches the stable version 1.0.0.

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

NEM2-SDK shares the same design/architecture between programming languages to accomplish the next properties:

  • Fast language adaptation: There is a library for Java, but you need it for C# for example, because both SDKs share the same design, you can re-write the library faster, just adapting the syntax to your language. It also applies to examples, projects, applications…
  • Cohesion/shared knowledge cross NEM developers: Be able to change between projects that use NEM, sharing the same design accompanied by the best practices.
  • Fast SDK updates: Migrating any improvement from a NEM2-SDK implementation to the rest is faster.
  • Fewer bugs: If any bug appears in one language, it is faster to check and fix it.

The best way to learn about the SDKs is through guides, we encourage you to check them.

Backward compatibility with NIS1 SDKs

Note

Final information regarding compatibility with NIS1 is not available yet.

Start planning the migration to NEM2-SDK to take advantage of new Catapult features and future releases.

Check Preparing for NEM2-SDK 1.0.0 to see new features and changes that break backward compatibility with NEM-Library.
