### I've undelegated but don't see it in my wallet yet. | How long does it take to undelegate?

From the moment the CTK is unstaked that amount will be undelegating for 21 days. You'll have to wait until this is done.\
If you want to verify this, you can always check <https://www.mintscan.io/shentu/> to verify the CTK unbonding on your wallet.

### Why is the APY different to the staking rewards I get?

The APY and Inflation are calculated according some parameters which can vary and make the actual rate.\
The APY is using the base calculation `Inflation% / staked% = APY%`\
Example would be : `10% inflation / 50% staked = 20% APY`\
However this is the base. This is not taking in consideration the current blocktimes, the blockreward for shield collateral providers.
