Clear.

Prove anything* about Yul programs.

There are two parts.

• A Lean framework with a Yul model.
• A verification condition generator.

The Lean framework

Download and install Lean 4. One can follow https://lean-lang.org/lean4/doc/quickstart.html.

Then simply run the following in the root directory:

lake build

The verification condition generator (vc)

Download and install Stack. One can follow https://docs.haskellstack.org/en/stable/install_and_upgrade/.

Then simply run the following in the vc directory:

stack build

Verifying it all works

In the vc directory, run:

stack run vc ../out/peano.yul

You should get a Generated folder corresponding with the structure of the Peano example in the out/peano.yul file.
