- -## Requirements -* Manticore requires Python 3.7 or greater -* Manticore officially supports the latest LTS version of Ubuntu provided by Github Actions - * Manticore has experimental support for EVM and WASM (but not native Linux binaries) on MacOS -* We recommend running with increased stack size. This can be done by running `ulimit -s 100000` or by passing `--ulimit stack=100000000:100000000` to `docker run` - -### Compiling Smart Contracts -* Ethereum smart contract analysis requires the [`solc`](https://github.com/ethereum/solidity) program in your `$PATH`. -* Manticore uses [crytic-compile](https://github.com/crytic/crytic-compile) to build smart contracts. If you're having compilation issues, consider running -`crytic-compile` on your code directly to make it easier to identify any issues. -* We're still in the process of implementing full support for the EVM Istanbul instruction semantics, so certain opcodes may not be supported. -In a pinch, you can try compiling with Solidity 0.4.x to avoid generating those instructions. - -## Using a different solver (Yices, Z3, CVC4) -Manticore relies on an external solver supporting smtlib2. Currently Z3, Yices and CVC4 are supported and can be selected via command-line or configuration settings. -If Yices is available, Manticore will use it by default. If not, it will fall back to Z3 or CVC4. If you want to manually choose which solver to use, you can do so like this: -```manticore --smt.solver Z3``` -### Installing CVC4 -For more details go to https://cvc4.github.io/. Otherwise, just get the binary and use it. - - sudo wget -O /usr/bin/cvc4 https://github.com/CVC4/CVC4/releases/download/1.7/cvc4-1.7-x86_64-linux-opt - sudo chmod +x /usr/bin/cvc4 - -### Installing Yices -Yices is incredibly fast.
