NFT layer 2 development is an area of active research and development in the Blockchain space. With the rise in popularity of non-fungible tokens (NFTs), there is a need for more scalable and efficient ways to store and trade them. Layer 2 solutions aim to address these challenges by providing off-chain solutions that can still be secured by the underlying Blockchain. This way, NFTs can be traded without clogging up the Blockchain and causing transaction fees to skyrocket.
