Building Solana NFT Indexer with Yellowstone gRPC: Hands-On Workshop

Step into the world of real-time blockchain data and learn how to build a high-performance NFT indexer on Solana using Yellowstone gRPC. Yellowstone gRPC provides a direct, low-latency stream of on-chain events straight from validator memory. While it may sound like overkill, this is exactly the kind of infrastructure used by advanced trading bots that outperform traditional approaches by leveraging speed that simply can’t be achieved with sequential RPC calls or polling. In this hands-on workshop, we’ll break down why real-time streaming matters  and how you can use it without building complex ETL pipelines. Unlike RPC-based indexing, Yellowstone allows you to subscribe only to the data you need: accounts, transactions, blocks, and more. This makes it not only powerful for trading use cases like sniping token launches or optimizing copy trading, but also surprisingly efficient for building analytics tools. What you’ll build By the end of the session, you’ll create a real-time NFT indexer that tracks holder activity and operations. As a practical example, we’ll simulate a scenario like calculating $BP allocation for Mad Lads holders, based on their on-chain behavior.
