GET ICO

GET ICO has 2 phases:

• PreICO:
  • Only whitelisted accounts.
  • limited to a specific amount.
• ICO:
  • different contract from PreICO
  • Only whitelisted acounts
  • 4 different pricing tiers. Pricing is calculated depending on the amount that is already invested. The price of the token follows the pattern:
    • Price is A between 0, x , x > 0
    • Price is B between x, y , y > x , B > A
    • Price is C between y, z , z > y , C > B
    • Price id D between z, w , w > z , D > C
  • Each account has a limit that he can buy on that tier.

CONTRACTS

GetToken:

• Tokenmarketnet CrowdsaleToken contract
  • 18 decimals
  • "GET" symbol
  • "Guaranteed Entrance Token" name
• No custom code

GetCrowdsale:

• Only responsible for the sale, we use a different contract for the presale. The reason is that we want to have different address for the sale contract which will be shared through our app in a different time.
• Tokenmarketnet MintedTokenCappedCrowdsale
• Custom code:
  • Enable the fallback function. We want an account to get tokens if he transfers money to the GetCrowdsale.
  • Disable setEarlyParicipantWhitelist function (not needed)
  • Implement a timelock on the finalize() function. The crowdsale will be able to be finalized (Token becomes tradable and more tokens are minted) after some time (3 weeks).
  • logPresaleResults: Moves the presale values to the crowdsale contract
  • preallocate: The default function was not adding the preallocated amounts as presale amounts, so it is overriden.

GetFinalizeAgent:

• Tokenmarketnet FinalizeAgent
• almost the same as BonusFinalizeAgent from Tokenmarketnet, but needs some customization for the specific amounts.
• Releases token
• Custom code:
  • Mints tokens to 3 multisig addresses
    • Bounty: 1800000
    • Stability: 12600000
    • userGrowth: percentage based on tokens sold (0.73170731707 * tokens sold)

GetPricingStrategy:

• Tokenmarketnet EthTranchePricing
• handles whitelist entries
• Custom code:
  • calculatePrice: needs to check if a user is part of the whitelist.
  • calculatePrice: needs to update the user limits in the correct Tier (called Tranche in the contract).
  • isPresalePurchase: always false, since we handle presale in a different contract.

GetWhitelist:

• Custom contract
• Ownable (zeppelin)
• whitelisters: list of accounts that can add accounts to the whitelist
• entries: whitelisted accounts. They start off with the caps defined
• WhitelistInfo: struct containing:
  • isWhitelisted bool
  • isEarly bool: for PreICO investors
  • presaleAmount uint
  • tier1Amount: uint
  • tier2Amount: uint
  • tier3Amount: uint
  • tier4Amount: uint
• setWhitelister: onlyOwner modifier. Owner can add or remove whitelisters
• onlyWhitelister modifier: only whitelisters can perform this action
• accept: onlyWhitelister modifier: add a new entry to the entries. Fails on existing one.
• acceptBatched: onlyWhitelister modifier: add multiple entries to the entries
• setCaps: onlyOwner modifier: change the tier caps
• subtractAmount onlyWhitelister modifier: reduces the amount that an account can buy in a specific tiers

GetPreCrowdsale:

• Only responsible for the presale, we use a different contract for the sale.
• Tokenmarketnet MintedTokenCappedCrowdsale
• Custom code:
  • Enable the fallback function. We want an account to get tokens if he transfers money to the GetCrowdsale.
  • Disable setEarlyParicipantWhitelist function (not needed)

GetPreFinalizeAgent:

• Tokenmarketnet FinalizeAgent
• Custom code:
  • updates Crowdsale with the amounts of GetPreCrowdsale

GetPrePricingStrategy:

• Tokenmarketnet FlatPricing
• Custom code:
  • checks whitelist
  • updates the presaleAmount of entries.
