The models' case: Fast, portable EVM toolkit with excellent Solidity-native tests, fuzzing, invariant testing, forked-chain simulation, debugging, scripting, and deployment. The models' main caveat: Solidity-centric workflows are less convenient for teams wanting TypeScript-first integration tests and extensive plugin-driven customization..
