A stable API means that the Sawtooth development team is committed to backward compatibility for future changes. Other APIs could change, which would require updates to application code.

The Maturity column shows the general maturity level of each feature:

  1. Recommended: Well supported and heavily used

  2. Community support only (core maintainers do not update these SDKs)

  3. Experimental: Might have known issues and future API changes
