How to stack CityCoins

share this

Anyone can "stack" CityCoins to earn rewards. Similar to staking, "stacking" is when you lock tokens (like STX, MIA or NYC) to provide a service to the network.

Stacking rewards are distributed in the token that powers the protocol: stack STX to earn BTC, stack a CityCoin to earn STX. (Here's more on why CityCoins builds on Stacks and Bitcoin)

What you need to know

  • When you stack CityCoins, you receive a portion of the Stacks (STX) transferred by miners as part of the mining process. The STX rewards you receive will be proportionate to the total stacked in that cycle.
  • Once you elect to stack your CityCoins, you must wait until the end of the reward cycle before you are able to claim your STX rewards. Reward cycles are approximately 2 weeks long. Your stacked CityCoins can be reclaimed once the selected stacking cycle(s) are complete.
  • You can stack tokens for up to 32 cycles at a time. There is a 1-cycle cooldown period after your selected number of reward cycles end.
