Status script for watching the status.im smartcontract crowdsale

web3-status-im-tokensale.js

/**
 * Johannes Zweng <[email protected]>, 2017
 *
 * This simple script just loads the Status.im contracts (Crowdsale and Tokens)
 * into the web3 Script API and then provides a single status function which you
 * can call on the console to query the current status of the crowdsale.
 *
 * Usage:
 *  1) Store this gist locally on your computer.
 *  2) make sure you have "web3" and "bignumber.js" node modules installed. For example like this:
 *       npm install web3
 *       npm install bignumber.js
 *  3) Load this script for interactive use into node:
 *
 *   #   node -e "eval(require('fs').readFileSync('web3-status-im-tokensale.js').toString())" -i
 *
 *  This will open an interactive node shell, from where you can enter
 *  the folowing 2 commands:
 *  
 *  >  status()
 *       or:
 *  >  ceilingInfos()
 *
 *  (Note: you can use the cursor-up key to easily repeat the last command.)
 *
 * The first will show you general infos about the current ICO state. The second one will 
 * display infos about the current dynamicceiling status.
