After shutdown, checkpoints are stopped, leading to possible theft of rewards.
ConvexStakingWrapper No more checkpoints after shutdown, i.e. no updates reward.reward_integral_for[user]
This would result in, after shutdown, being able to steal rewards by transferring tokens to new users.
Example:
Suppose the current
reward.reward_integral = 1000
When a shutdown occurs:
Since Bob is the new user and _beforeTokenTransfer()->_checkpoint() is not actually executed.
Result:
balanceOf[bob] = 100
reward.reward_integral_for[bob] = 0
reward amount = balanceOf[bob] * (reward.reward_integral - reward.reward_integral_for[bob])
= 100 * (1000-0)
Still execute \_checkpoint
