Yes, staking an NFT typically involves gas fees, as it requires interactions with the blockchain, such as approving, depositing, or withdrawing your NFTs. Gas fees are paid to the network (e.g., Ethereum or BNB Smart Chain) for processing and validating the transactions. The amount of gas required depends on the complexity of the transaction and network congestion at the time of staking. Gas fees can fluctuate and might be higher during periods of increased network activity.
