####Behaviour: -anybody can invest in the campaign startTime - endTime interval -campaign is closed after endTime -target can be exceeded -if target is not reached at endTime investors can ask for a refund for an undefined period -if target is reached and endTime has passed, anybody can call forward funds function that will transfer raised ether according to the beneficiary schema

####Set-up Owner can configure beneficiary schema using function registerBeneficiary. A beneficiary schema represents a list of addresses and percentages of raised funds.

####Owner should call registerBeneficiary three times:

  • definition of const crowdsale as a web3 contract
  • crowdsale.registerBeneficiary(""0x0000000000000000000000000000000000000001"", 25, { from: web3.eth.coinbase });
  • crowdsale.registerBeneficiary(""0x0000000000000000000000000000000000000002"", 30, { from: web3.eth.coinbase });
  • crowdsale.registerBeneficiary(""0x0000000000000000000000000000000000000003"", 45, { from: web3.eth.coinbase });

####Finalization After the crowdsale has ended there are two scenarious, target reached or not.

####Target reached

  • Anybody can call forwardFunds function that will transfer the investments to the beneficiary schema. Keep in mind some constraints will apply:
  • raised >= target // raised wei amount greater than target set at initializtion
  • forwarded == false // funds should not be already transfered
  • totalPercentage == 100 // sum of beneficiary schema percentages should be 100

####Target not reached

  • Investors can call refund function and they will receive investments back."
