Monitors DeFi protocol user retention metrics on Base, tracking cohort retention rates for users who first interacted with each protocol, measuring what percentage remain active at 30, 60, and 90-day intervals. Identifies protocols demonstrating strong user retention that indicates genuine product-market fit versus those experiencing rapid user churn driven primarily by short-term incentive farming behavior. Delivers monthly user retention intelligence as on-chain attestations with cohort analysis and retention benchmark comparisons.
