Abstract
The Aptos Framework is a collection of smart contracts written in the Move language that define standard and common on-chain actions for the Aptos Network. As the security and safety of the Aptos Framework is of utmost importance, it has continuously undergone rigorous testing and comprehensive auditing. To further increase the level of assurance, we have formally verified its security and correctness. This involves identifying critical security requirements for each module, creating formal specifications, and subsequently verifying them using the Move Prover. To the best of our knowledge, this represents one of the first instances of formal verification being applied on such a large scale in a smart contract framework. This paper discusses how this rigorous effort ensures a high level of quality assurance for the Aptos Framework.
