# Staking duration

You stake STX for 1 to 96 reward cycles, can unstake earlier, and can extend before the scheduled end.

The staking duration is the number of reward cycles your stake runs, from 1 to 96. A cycle is 2,100 Bitcoin blocks (about two weeks), so 96 cycles is about four years.

* The duration sets the scheduled end. Leather shows it as "Scheduled end".
* You can unstake before the scheduled end, outside the last 100 Bitcoin blocks of a cycle. Your STX unlocks at the end of that cycle.
* You can extend with "Cycles to extend". The total stays within 96 cycles.

Liquid staking providers set their own redemption terms.
