Solana is a Layer 1 blockchain that offers users fast speeds and affordable costs. It supports smart contracts and facilitates the creation of decentralized applications (dApps). Projects built on Solana include a variety of DeFi platforms as well as NFT marketplaces, where users can buy Solana-based NFT projects. Its high performance means Solana doesn’t require a traditional scaling Layer 2 solution; instead, Layer 2s on Solana focus on interoperability and connecting Solana to other chains.
