Want to maximize your $CAKE rewards without locking your $CAKE? from pancakeswap
Or just use the Flex Cake vault at https://happyhippo.farm/ to save you gas fees and time.
32% APY is equivalent to locking for 12 weeks yet using this method you don’t have to lock and can remain flexible.
I’ve been using that vault for some time and the good thing is that they’ve completed the move from ANKR to METIS pool transparently without requiring any user-side actions.
