Users can cancel DEP staking in batches, and the canceled batch is independent of each other. For example, if a user named Alice has staked 100,000 DEPs, she can choose to cancel the stake of 10,000 DEPs on January 1st and January 2nd respectively. Then the cooldown period will end on January 8th and January 9th. 10,000 DEPs can be withdrawn started from different days. The cooldown lock-up period for different batches can be queried on the unstake page.
