Low SDK or high SDK

Hello friends
I had a question. Do we need to have all the SDKs that are about 50 GB? Or if we only have the top SDK, can we write for the bottom as well?
Thank you for your help.

Hi @ideawebsiteir, thanks for using the devforum.

Can you please clarify which platform you are using the SDK with? I’m also not sure what you mean by top or bottom SDK, but clarifying the platform may clear that up. :slightly_smiling_face:
