INTERACTIVE ARCHITECTURE DIAGRAM
V2's architecture bears resemblance to V1, incorporating similar components such as Vault Factory, Vaults, and Controller. However, V2 also includes substantial enhancements in the form of new Carousel and CarouselFactory functionalities.
In contrast to V1, VaultV2 is a SemiFungibleVault token based on the ERC1155 standard. The position Id or
epochId is now a hash composed of (marketId, epochBegin, epochEnd), which can be deterministically computed using the getEpochId function on the VaultFactoryV2 contract.Shares continue to be minted 1 to 1, but in V2, the depositAsset can be any ERC20 token as defined by the VaultFactoryV2.
Unlike in V1, the withdraw fee in V2 is deducted when the vault is settled. The user's entitlement is then calculated based on the percentage of shares they had in the Vault before the insurance epoch began.
Users can opt to rollover existing positions into the next available epoch using the
enlistInRollover function, specifying the epochId, shares, and receiver. To cease rollovers, users can invoke the delistInRollover function. Pending rollovers can be minted by anyone calling the mintRollovers function during an active deposit window. V2 permits users to deposit at any time using the deposit function with an
id of 0. A QueueItem is minted and later redeemed for a position in the next epoch deposit window. Any party can call the mintDepositInQueue function during an active deposit window to redeem all stored QueueItems.The marketId and epochId can be calculated using the getMarketId and
getEpochId functions, respectively.CarouselFactory is an extension of the VaultV2Factory contract. It differs in the creation of markets and configuration of epochs which are handled through createNewCarouselMarket and createEpochWithEmissions respectively.
A significant improvement is that y2k emissions can now be configured and distributed within each epoch, eliminating the need for deploying an extra StakingRewards contract.
