Announcement: Isabelle/Solidity

Ever wondered how to verify smart contracts written in Solidy? Thanks to our deep embedding of Solidty into Isabelle/HOL, you can now start verifying smart contracts in Isabelle.

Our formalization is available in the Archive of Formal Proofs [1], which can be easily added to Isabelle/HOL. If you want to read a more high-level description of the underlying work, read our conference papers on the topic [2].
