As per the report, in the short term, 35–45% of new users were retained by both Arbitrum and Optimism, although Optimism retained a larger percentage of its long-term user base.

Though both the short- and long-term retention rates are valuable metrics, the latter is more important in order to understand the value of a blockchain.Moreover, Optimism’s long-term retention was considerably higher than that of Arbtrum, suggesting more users’ trust in the L2 blockchain.
