In this blog post, we show how we state the functional correctness of the implementation of the STATIC_CALL instruction in Revm, an implementation of the Ethereum's virtual machine EVM in Rust. This involves running rocq-of-rust to translate the Rust code to the theorem prover Rocq, and then making a proof by refinements until obtaining a specification of the code written in purely functional style, optimized for formal verification. This also proves the code cannot panic, as our specifications are free of panics.

In this blog post, we present how we specify and verify the implementation of the ADD instruction of the EVM virtual machine in Rust.

We give a functional specification, meaning that we show the implementation to be equivalent to an idealized version written in the Rocq language. As the Rust code for this instruction involves rather advanced features of Rust, the same techniques could apply to verify a large set of Rust programs.
