manticore

Ugh, I have been advocating "Solidity--" for years and can't get funding to build it (Trail of Bits). We use two tools to offer quick turnaround automated testing and verification for Solidity: Echidna (like QuickCheck for Solidity) and Manticore (a symbolic verifier). They each let you write high level properties in the span of 1-2 weeks that cover a large amount of potential use cases. Here's an example of what that looks like: https://github.com/trailofbits/publications/blob/master/revi... Here's Echidna: https://github.com/crytic/echidna and Manticore: https://github.com/trailofbits/manticore Sometimes we also use custom static analyses built around Slither's IR during projects too: https://github.com/crytic/slither/wiki/SlithIR

fwiw there's a popular symbolic execution tool with the same name https://github.com/trailofbits/manticore Just got confused for a sec.

Manticore in the post above uses formal methods to verify contract properties! https://github.com/trailofbits/manticore
