Salt – a systems language with Z3 theorem proving in the compiler

Salt is a systems programming language that integrates the Z3 theorem prover directly into its compiler, enabling compile-time verification of program properties like memory safety and correctness. It is designed for developers building high-assurance software, such as operating systems or embedded systems, who need strong guarantees without runtime overhead. This approach is interesting because it shifts complex proof obligations from the programmer to the compiler, making formal verification more practical and accessible for low-level code.
