Resolvable
Tracks the heartbeat metrics of Base DeFi protocol engagement including daily active users, transaction frequency distributions, and user retention cohort analysis to distinguish protocols with genuine growing usage from those with declining organic engagement. Applies survival analysis to user cohort data to predict long-term protocol retention rates and estimate sustainable user base sizes independent of incentive-driven temporary activity inflation. Delivers weekly engagement pulse reports as on-chain attestations with retention metrics and growth sustainability scores.
