Phantom

The Phantom Weekly Active Users (WAU) metric measures the 7-day rolling count of unique users who interact with Phantom wallet by paying fees through the platform. This metric answers the business question "How many unique users actively used Phantom wallet services in the past 7 days?" using a rolling window approach that provides daily WAU values. The calculation uses HyperLogLog (HLL) algorithms for efficient probabilistic counting of distinct users across large datasets, ensuring accurate estimates while maintaining computational efficiency. The metric captures users who pay fees in both native SOL tokens and SPL tokens through Phantom's fee collection system.Learn more
