This paper gives a brief description of the KeY system, a tool written as part of the ongoing KeY project1, which is aimed at bridging the gap between (a) OO software engineering methods and tools and (b) deductive verification.
The KeY system consists of a commercial CASE tool enhanced with functionality for formal specification and deductive verification.
The KeY project is supported by the Deutsche Forschungsgemeinschaft (grant no. Ha 2617/2-1).
