Using the dYFI Redeemer
Approving
Users only need to approve the dYFI Redeemer contract once to participate in dYFI→YFI redemptions. Once the dYFI Redeemer contract is approved users will asynchronously start redeeming YFI for dYFI every time the Redeemer contract is called.
Redemption is permissionless so any user can redeem if they wish to and are
periodically processed by keeper bots.
