Layer 2 solutions are secondary frameworks built on top of existing blockchain networks that enhance scalability and efficiency. By processing transactions off the main blockchain (Layer 1), these solutions significantly reduce congestion, leading to faster transaction times and lower fees. This is particularly beneficial for NFT marketplaces where high transaction volumes can lead to delays and increased costs. The implementation of Layer 2 solutions aims to create a seamless user experience, allowing for rapid trading and minting of NFTs without the typical bottlenecks associated with Layer 1 transactions.
