Optimism mainnet active addresses increased nearly 20-fold, reaching a 30-day high

Optimism (OP) mainnet daily active addresses surged nearly 20-fold to a 30-day high, The Defiant reported, though transaction growth lagged the address increase and user-paid fees stayed close to the prior seven-day median. Active addresses count unique addresses that initiated a transaction in a day, so the metric can overstate real user growth since one person may operate multiple addresses. Transaction counts and user fees measure different dimensions of activity, making it difficult to infer transaction intensity or cost changes from address numbers alone. The divergence between address and transaction growth suggests the spike may partly reflect address-level behavior rather than a proportional rise in on-chain demand. Watch whether transaction counts and fee levels catch up in the coming days to confirm the activity increase is broad-based.
