Imagine that you are an ETH whale and accumulated a lot of dETH in your own savETH index. You now want to fractionalize the index. You can now allow users to purchase small fractions of dETH that are earning inflation rewards on the Beacon Chain in order to get exposure to this new premium asset class.
Put simply, the smart contract is an ERC20 smart contract that mints a fixed supply of shares that represent a fractionalized stake in a savETH index of dETH KNOTs earning yield. Simply deploy the contract and use the ID of the created index when adding KNOTs to a Stakehouse in order to ensure that the dETH is correctly owned by the index and then by extension owned by the smart contract. Add any further logic you desire!
