Stacks operates on a fixed cycle schedule, where each Stacking cycle lasts approximately two weeks. To earn Bitcoin rewards through Stacking, you must delegate or commit your STX before the next cycle begins.

Each cycle includes:

• A preparation window where new delegations are collected

• A locking period where STX is held and earns yield

• A reward distribution after each cycle completes

Leather shows a countdown timer and highlights upcoming cycles in the interface. You’ll be notified in advance when it’s time to join, and can delegate STX with a few clicks.

To maximize your chances of being included, submit your delegation at least 1–2 blocks before the cycle rolls over.
