# Minimum lock period for staking

The shortest time STX stays locked when you stake, one reward cycle.

The shortest stake is one reward cycle: 2,100 Bitcoin blocks, about two weeks.

An unstake does not unlock STX at once. Your STX unlocks at the end of the cycle in which the unstake confirms. Unstaking is closed in the last 100 Bitcoin blocks of every cycle.
