hevm is an open source, state-of-the art, fast symbolic and concrete EVM execution engine that can find issues in smart contracts. Through its symbolic execution and analysis system, hevm can symbolically, semi-concretely, or concretely execute contracts to find bugs, or compare two different contracts for discrepancies, performing equivalence checking.
