Layer 2 Review Issue #28
Title | Layer 2 Review
Quick Reads and Hot Links Covering the People and Projects Who Are Scaling Ethereum
Dear Frens,
Welcome to the L2 Review, where we provide the latest developments, insights, and emerging trends in the dynamic layer 2 ecosystem.
Optimism’s Retroactive Public Goods Funding (RetroPGF) 6 will see up to 3.5 million OP distributed among contributors to Optimism Governance during Season 5 and Season 6. This means that impact from October 2023 to September 18, 2024, will be rewarded to contributors to Optimism Governance. The focus includes infrastructure and tooling, governance analytics, and leadership within the superchain governance. Applications were opened today and will run till October 10. For more details on eligibility and the application process, click here.
Base is rolling out a global series of regional buildathons, targeting Africa, India, Southeast Asia, and Latin America. From September 27 to October 13, these events will offer a total prize pool of 100 ETH for teams building onchain applications that address local community challenges. This initiative shows Base's commitment to empowering non-US builders (74% of total onchain builders), and driving the adoption of onchain tech for impactful solutions.
L2s are pushing boundaries across governance, innovation, and beyond with no sign of them slowing down. Count on us to bring you timely updates and insights into these advancements that shape the ecosystem’s future.

Starknet Takes Big Step in Layer 2 Staking
Starknet is making waves by being the first to offer staking services on Ethereum layer 2, showing its commitment to decentralization. This means users can now earn rewards by staking their STRK tokens. While it will take some time for Starknet to transition to a full PoS network, the first part of staking has already begun. The community got to vote on important details about how staking will work. Starknet plans to test this new system later this year, with the live version launching around the same time. Currently, experts are auditing the staking contract to ensure it's safe to use. Interested in learning more? Check the X post below for more details.

Activity on Ethereum’s Layer 2 networks has been nothing short of phenomenal. Top projects like Base, Arbitrum, and Optimism are stealing the show from Mainnet, bringing to life the scalability vision. Base L2 is making and breaking records, hitting new highs in terms of onchain metrics. Following the broader market recovery, top L2 native tokens like ARB and OP have also risen from their lows.
In this article, we review activity so far among the top three Layer 2 projects this month, especially focusing on onchain metrics and developer activities. What do the numbers tell us about Layer 2 progress in these past weeks? Let’s find out!
Onchain Metrics
We can measure onchain activity using several yardsticks. Among them, two stand out to give a picture of the extent of usage, they include the number of active addresses and transaction count.
The number of active addresses on a network tells of the number of addresses trafficking the chain within a specified amount of time. It indicates the number of unique addresses that are involved in a successful transaction (as a sender or receiver) within the network and can be a major indication of activity. Transaction count, on the other hand, is the total amount of unique transactions that occurred on a network within a particular timeframe.
Both metrics are not perfect indicators of human onchain activity as several factors can influence the number of active addresses and transaction count including market sentiment and bot activity. Nevertheless, they are still significant enough to describe the extent of usage.
What Do the Numbers Say?
According to data from GrowThePie, so far in the past 30 days, Base has stood tall with over 20M active addresses, a 53% increase from the previous month. The network hit a new all-time high in active addresses on Sep. 21 with about 1.5M addresses engaging in over 4.7M transactions on that single day. Base is the first Ethereum L2 to hit these numbers.
Arbitrum One and OP Mainnet on the other hand have so far had 2.7M and 1.01M active addresses respectively this month. At the time of writing, transaction count on both networks in the past day were 1.78M and 751k respectively. In comparison with Ethereum mainnet, so far in September, the network has recorded 4.7M active addresses and 1.1M transactions in the past day.
The chart of active addresses and transaction count on the top three L2 networks are proceeding in opposite directions as Base seems to be soaring on a lane of its own. While there is a steady increase in the count from Base, Arbitrum and Optimism’s count seems to be in decline.

It’s no news that Base has been on an explosive run this year in terms of onchain metrics. The recently concluded Onchain Summer event, the launch of basenames, smart wallets and other factors could be further fuelling the growth of the network. Can Base sustain the heat?
Developer Activity
The number of devs actively working on a project and building on the network is an important metric to determine how a blockchain network is evolving. More developer activity signals faster development; and new and improved initiatives would attract more users, ultimately boosting the network’s activity. As such, many networks put up several programs and incentives to attract devs. The aim as always is to make the chain as builder-friendly as possible.
Developer activity can be in the form of core devs building and maintaining the network’s underlying infrastructure and dApp or smart contract devs using the network’s tools to spin out several use cases for the chain.
According to data from DeFi Llama, Base currently has 14 core devs actively working on the network in September. In contrast, Arbitrum and Optimism have 39 and 47 core devs respectively. Ethereum mainnet remains the central hub for devs with 352 core devs in September.
On the scene of smart contract deployment, according to data from Nansen, daily deployment on Base hit a peak of 644k and a low of 102k since the beginning of September. On Arbitrum, deployments have ranged between 4.4k and 32k so far this month, that of Optimism was between 12k and 131k. Ethereum mainnet on the other hand had a high of 88k and had since dipped to about 3.5k smart contract deployments.
This data shows that more smart contract devs are trooping to Base to launch their projects. It’s not surprising as Base currently offers the fastest throughput in the entire Layer 2 ecosystem and offers one of the lowest (near zero) transaction fees.
The Future is Here?
On several fronts, from active addresses to transaction count, Layer 2 solutions are displaying the scalable potential of Ethereum, flinging the doors wide open for global adoption. It’s interesting to see the rapid development of projects like Base, taking over the stage in a very short time. As Ethereum continues to build on its rollup-centric model for scaling, we will most likely see new developments that will outpace the current standards. We are not in the future yet but it’s closer than it had ever been.
