Inside an Aptos Move Smart Contract Audit: What Developers Should Expect
The MOVE language, originally developed for Meta's Diem and now utilized by Aptos, redefines smart contract security by treating assets as non-duplicable resources. This design inherently mitigates classic vulnerabilities like reentrancy but introduces new challenges in capability management and module visibility.
Audits for Move-based contracts focus on validating logic safety under all conditions, emphasizing resource lifecycle integrity and privilege tracking. Unlike traditional syntax checks, these reviews scrutinize how design assumptions interact with Move's ownership model.
Key audit findings often center on three areas: unrevoked capabilities granting excessive access, unintended exposure of private functions through friend modules, and inconsistent resource handling. Aptos developers must prepare for rigorous testing of edge cases—Move's architectural safeguards shift rather than eliminate risk.
