User growth was propelled by the second largest new cohort size to date. Last week, 225,083 new users experienced Polygon PoS for the first time.
This marks the third consecutive week of new user growth. For the previous two months, cohorts have been well above 100,000.

Even more impressive, retention continues to improve across cohort groups.
In the oldest cohorts, retention notched another week over week improvement, coming in at 21.69%. In other words, retention has not decreased for these users in over four months! (17 weeks).
We are also seeing very promising retention metrics with the latest cohort aggregation of chorts 21-30. This week retention spiked up to 20.18%, the highest retention rate since week 22.

We see this increase in users have led to a sizeable increase in daily transactions (+13.42%). Currently Polygon PoS is averaging 6.5mm transactions per day and has increased steadily in seven of the last eight weeks.

Part 2: Polygon PoS monetization growth
Network revenues continue to experience a lot of volatility.
After declining 39.37% last week, revenues increased 26.61% to $38.7k a day.
Revenue increases were aided by both an increase in gas used as well as a 28.56% increase in average gas price.
Objectively, Polygon is handling the growth in users and transactions well from a cost perspective. Last week the average transaction cost remained well below a cent, at an average price of $0.0059.
