Initial Ape Offering

This set of contracts is used to run Ape Swap's version of initial farm offerings. This set of offering contracts provides for vesting periods. These vesting periods divide the offering tokens into equal parts and allows for the release of each part after each harvest period ends.

Operation

• Each IAO raises a predefined stakeToken amount in exchange for a predefined offeringToken amount
• Once the startBlock arrives, users can supply as much of the raising token as they would like
• Once the endBlock arrives, users can withdraw their first harvest and obtain a refund

Linear Vesting

IAOLinearVesting.sol
25% of tokens are released at the endBlock of this IAO and the other 75% are distributed linearly between the endBlock and vestingEndBlock.

• vestingEndBlock is set to define when all of the offering tokens will be 100% unlocked.
• A refund of stakeTokens when there is an oversubscription of the IAO will be given on the first harvest
• offeringTokens are sent to users based on the number of vesting blocks that have passed since the end of the IAO. 25% is released on the first harvest along with a refund for over-subscriptions

Period Based Vesting

IAO.sol

• harvestPeriods set the block when new vesting tokens may be unlocked. After enough time elapses, a user will be able to withdraw the next harvest until there are no more
• A refund of stakeTokens when there is an oversubscription of the IAO will be given on the first harvest of any period
• offeringTokens are sent to the users based on the percentage of their allocation divided by the number of harvest periods
