Scalability is essential for NFT marketplaces, especially as demand increases. Opt for blockchains with high transaction throughput and consider layer 2 solutions for off-chain transactions. Implement scalable infrastructure, such as cloud-based servers, to handle traffic spikes. Load balancing and caching can improve performance, reducing latency. Employ modular architecture for easy expansion, allowing your platform to scale as user demand grows. By focusing on scalability, you ensure a seamless user experience, even during peak times.
