Boost APR refers to the act of staking tokens to reduce the time it takes to receive the reward for any staked NFTs.
Boost APR can be applied only when the mining model of NFT staking is in progress.
When staking multiple NFTs, the Boost APR applies to all staked NFTs equally. It is not possible to apply the boost to specific NFTs.
Additional boost staking is unavailable when boosting APR. In order to add more volume to boost staking, the user must unstake the original amount and restart the staking process with the new amount.
