A Sound Semantics Approximation of Solidity for Enhanced Vulnerability Detection

As Solidity smart contracts become central to decentralized finance and governance, the exploitation of critical vulnerabilities has repeatedly resulted in severe financial losses. Existing state-of-the-art methods that rely on symbolic execution or syntactic patterns are unable to model the language semantics accurate...

Don't Just Translate: Verify - LLM-Guided Solidity Migration with Semantic Guarantees

: Smart contracts operate in immutable blockchain environments where preserving correctness during software evolution is critical. The transition from Solidity 0.5.x to 0.8.x introduces important safety improvements but also semantic changes that make manual migration of legacy contracts error-prone. Although large lan...
