Arbitrum One just had its busiest day in three months, at least by one measure. Daily active addresses on the Ethereum layer-2 network climbed to 571,767 before activity eased after October 22, The Defiant reported.
The numbers behind the spike
Data from growthepie, updated October 22, 2026, puts daily active addresses at 571.8K. That marks a 90-day high and a 408.2% week-over-week jump.
Transactions told a calmer story. They reached roughly 1.7 million, up 25.7% from the prior week.
That volume was still enough to rank Arbitrum One fifth among the chains growthepie tracks.
Revenue moved in the opposite direction. Chain revenue came in at $19.3K, down 2.4% week-over-week.
DefiLlama’s numbers broadly agree on the headcount. The analytics platform reported 570,079 active addresses as of October 22, 2026, alongside total value locked (TVL) of $1.45B.
Where the activity came from
No single trigger stands out. The research points to broadly heavier network usage rather than one identifiable catalyst.
The biggest contributors to transaction volume were plain native ETH transfers and stablecoin transactions involving USDC.
Stablecoin figures depend on which dashboard you open. Growthepie showed stablecoin supply at $4.39B, down 5.8% week-over-week, while DefiLlama put the stablecoin market cap at around $3.5B.
Context: a choppy year for Arbitrum users
Arbitrum One is one of the leading optimistic rollups on Ethereum. It processes transactions off the main chain and settles them back to Ethereum, which keeps fees lower for users.
Its user counts have swung widely in 2026. Earlier figures from other dashboards showed weekly active addresses ranging from 400K to 1.7M, depending on the exact window measured.
The spike also followed a stretch of lower activity. That base effect helps explain why the week-over-week percentage looks so large: growth from a quiet week always photographs well.
What this means
For investors and builders, the most telling detail is the mismatch between addresses and transactions. When users surge but transactions per user fall, the new arrivals are likely doing very little once they land.
A decline in stablecoin supply on growthepie during a week of rising addresses hints that capital and users were not moving in lockstep.
Arbitrum ranked fifth by transactions among tracked chains, which places it in a crowded field of Ethereum scaling networks fighting for the same users and liquidity.
Three metrics are worth tracking from here: daily active addresses relative to the 571,767 peak, transaction growth against that 1.7 million mark, and whether chain revenue climbs back above $19.3K.
