Realising contract-based applications from formal specifications with formal guarantees requires to show the adherence of a specification, the contract, to its implementation. Contract automata have been introduced for specifying contract-based applications and synthesising their orchestrations as finite state automata. This paper introduces CARE, a newly developed library for implementing applications specified via contract automata, providing a runtime environment to coordinate services implementing contracts.
