Will I be able to see my staking rewards on the Stakeboard?

Stakeboard is software, not a wallet, and does not actually hold KILT Coins. Therefore you don't see your staking rewards directly.

However, as the rewards go directly back to the account they were staked from, you will see the STAKEABLE total rising on Stakeboard as they are added.

If you wish to restake these KILT Coins, you will need to do this manually. Follow the instructions in the "How do I increase my stake?" question.
