Token Wizard Strategy

At the moment, the Wizard supports one type of crowdsale contract, the mighty "whitelisted with tiers and cap". This strategy is popular in modern ICOs due to regulatory involvement in the process (September 2017). A native approach to comply with regulation is to perform KYC of buyers and restrict participants from democratic countries, e.g., the U.S. or PRC.

Features of "Whitelisted with tiers and cap" strategy:

• Tiers. A crowdsale can have one or more tiers. Each tier has a set of configurable parameters:
  • Wallet address. Collected funds will be sent to the wallet address immediately after receiving from a participant of the crowdsale.
  • Start time. A time when a tier of crowdsale will start. You can't set up time in the past.
  • End time. A time when a tier of crowdsale will end.
  • Rate. Exchange rate for a token to the ether. E.g., exchange rate 100 means that for one ether you can buy 100 tokens.
  • Supply. The maximum amount of tokens available to buy in a tier. Max cap of the crowdsale equals to the sum of all supply of all tiers.
  • Allow modifying. Controversial feature aka "Box of Pandora". It allows owners to modify Start time, End time, Rate, and Supply after the crowdsale.
• Whitelist. A crowdsale can have one or more whitelisted addresses. If there are no whitelisted addresses than nobody can buy tokens on that tier. Whitelists are inherited. E.g., if a user was on Tier 1 and didn't buy max cap on Tier 1, he can buy on Tier 2, and other tiers. Can be updated after the creation of the crowdsale using parity client. Each whitelist has a set of configurable parameters:
  • Address. Whitelisted ethereum address.
  • Min. The minimum amount of tokens to buy.
  • Max. The maximum amount of tokens to buy.
