I deposit some badger in my vault but can not find the stake button, there is no need for staking anymore? I still have some staked badger in my vault. Should I unstake it now? Thx.
Yes, staking is not required anymore, this was announced in order to simplify the process and also save on gas fees. Just deposit.
You can unstake whenever you want (now, or when you are ready to withdraw). Considering the current low gas prices I decided to unstake recently, while keeping my deposits and continuing to earn on them.
