  • used node.js, web3 and solc compiler
  • Used truffle framework in order to the ease tdevelopement process
• Testing of smart contracts was done on
  • testrpc
  • geth (private blockchain)
• Testing was done using javascript instead of a solidity contract creation way.
• Java script testing method used the Mocha framework
