solgraph

solgraph

Generates a DOT graph that visualizes function control flow of a Solidity contract and highlights potential security vulnerabilities.

Install

$ npm install --save -g solgraph

Usage

$ cat solgraph MyContract.sol > MyContract.dot
strict digraph {
  MyContract
  Mint [color=gray]
  Withdraw [color=red]
  UNTRUSTED
  GetBalance [color=blue]
  MyContract -> Mint
  Withdraw -> UNTRUSTED
}

You have to install graphviz to render the DOT file as an image:

$ dot -Tpng MyContract.dot > MyContract.png

The above example uses the following MyContract.sol:

contract MyContract {
  uint balance;

  function MyContract() {
    Mint(1000000);
  }

  function Mint(uint amount) internal {
    balance = amount;
  }

  function Withdraw() {
    msg.sender.send(balance);
  }

  function GetBalance() constant returns(uint) {
    return balance;
  }
}

Node Module

import { readFileSync } from 'fs'
import solgraph from 'solgraph'

const dot = solgraph(fs.readFileSync('./Simple.sol'))
console.log(dot)
/*
Foo
Bar
Foo -> Bar
*/
