Defines a specification style that proves concrete guarantees: sound reasoning under arbitrary re-entrancy, modular verification of collaborating contracts, and resource-centric assertions that prevent duplication or unauthorized destruction. Implements the approach in 2vyper, an SMT-based verifier for Vyper built on the Viper infrastructure, and applies it to ERC-20 variants, a callback-heavy token, multi-contract apps and Uniswap, successfully producing concise, machine-checked proofs of strong correctness properties.
