SKLEE: A Dynamic Symbolic Analysis Tool for Ethereum Smart Contracts (Tool Paper)

  • Conference paper
  • First Online:
Software Engineering and Formal Methods (SEFM 2022)


We present SKLEE, a dynamic symbolic framework to analyse Solidity smart contracts for various safety vulnerabilities. While there are many analysis tools for Solidity contracts, in this work we demonstrate that existing analysis infrastructures for other sequential programming languages, such as C, can be leveraged to construct a competitive analysis framework for Solidity contracts. Notably, SKLEE is bootstrapped on top of KLEE – a dynamic symbolic test-case generation tool for C programs – with modelling for Solidity primitives such as send, call, transfer, and others. Our experiments indicate that SKLEE is indeed competitive with other state-of-the-art tools in terms of (i) the number of bug classes it can identify, and (ii) the number of benchmarks it can analyse in a given time bound.
