Boosties offers a special public good mechanism that allows users to claim
YFI directly from their dYFI without needing ETH.The redeemer contract just needs to be approved once for users to earn YFI
from their dYFI earnings. Using Yearn’s Redemption contract and by
flashloaning ETH, users can more effectively acquire YFI. This process
occurs asynchronously and is also gas-free for users not calling the redeemer
contract.When a user calls the redeemer contract it claims dYFI→YFI and sends
YFI to all users that have already approved the redeemer contract. Anyone
can call this contract as it is permissionless. Any extra ETH that is returned
in excess of the minimum amount is sent to the caller to incentivize
automation. Users can opt-out of the redemptions by revoking the approved
contract from their respective address.To make things easier for users, redemptions will be processed by keepers
periodically.
