Formally Verifying a Real World Smart Contract

Abstract

Nowadays, smart contracts have become increasingly popular and, as with software development in general, testing is the standard method for verifying their correctness. However, smart contracts require a higher level of certainty regarding correctness because they are diffcult to modify once deployed and errors can result in significant financial losses. Therefore, formal verification is essential. In this article, we present our search for a tool capable of formally verifying a real-world smart contract written in a recent version of Solidity.
