The NFT + ART Stable Pool requires you to lock your NFTs for six months to get the full reward. You can unstake your NFTs at any time, under penalization. If you reach the minimum staking period of 2 months, you can claim 50% of the reward, and the smart contract will return the remaining amount to the pool. If you unstake your NFTs before the minimum staking period (2 months/8 weeks), the reward will be fully returned to the pool. If you unstake your NFTs after the entire period (6 months/24 weeks), you will get the full reward.
