Starknet is leading Layer 2 developer activity as Ethereum scaling competition heats up, putting focus on builder momentum, adoption, and network positioning.
Starknet has moved to the front of the Layer 2 developer race, giving the Ethereum-focused ZK rollup a meaningful momentum signal as competition to scale the network keeps intensifying.
What to Know
- Starknet is leading Santiment’s latest Layer 2 developer activity ranking, putting builder momentum at the center of its Ethereum positioning.
- That lead matters because networks that keep attracting code commits and core contributors are usually in a stronger position to win apps, tooling, and liquidity in the Ethereum scaling market.
Why Starknet Is Leading Layer 2 Developer Activity
Santiment’s March 5, 2026 Layer 2 ranking put Starknet in the top spot, with Aztec second, Arbitrum third, zkSync fourth, and Optimism fifth.
Santiment said the ranking is based on GitHub activity and month-over-month direction changes, which means developer activity in this context is a measure of sustained repository work rather than token performance or short-term trading attention.
The separation between the leading projects is wide enough to matter. BanklessTimes said Santiment’s dataset gave Starknet a 30-day development activity score of 213.97, versus 93.67 for Arbitrum and 57.27 for Optimism. That spread implies Starknet is not just edging rivals out in current builder attention but establishing a clearer lead in the latest snapshot.
L2Beat describes Starknet as a ZK rollup that uses STARK proofs to scale Ethereum and Ethereum blobs for data availability. That matters in the current race because it ties Starknet’s builder lead directly to one of Ethereum’s main technical paths for adding capacity without changing the base layer’s role as settlement.
Blockchain.News separately reported the same top-five order and GitHub-based methodology, reinforcing that the headline here is about verifiable development ranking data rather than marketing claims from any single project.
Santiment also summarized the ranking in a public X post that highlighted the same leader board and directional changes from the previous month.

What Starknet’s Momentum Means for the Ethereum Scaling Race
DefiLlama’s Ethereum page shows more than $118 billion in total value locked, which is why even a developer-activity ranking matters: Layer 2 teams are competing to serve an ecosystem with a still-massive capital base.
The Starknet lead is more significant when paired with the gap between its 213.97 development score and Arbitrum’s 93.67 and Optimism’s 57.27. Builder momentum at that scale can translate into faster tooling upgrades, more application experimentation, and a stronger case that developers see Starknet as a serious venue for future Ethereum activity.
The broader infrastructure story also fits with the kind of long-horizon positioning implied by Santiment’s development ranking. Coverage of Visa’s move onto Tempo as an anchor validator points to growing institutional interest in blockchain infrastructure, while the Bitcoin ETF buildout on Wall Street shows capital markets are paying closer attention to the asset class overall.
That does not make developer activity a perfect predictor of adoption. It does, however, make it a useful leading indicator when the metric is tied to a concrete ranking from Santiment’s Layer 2 dataset and to an Ethereum opportunity set that DefiLlama still measures in the hundreds of billions of dollars.
What Investors and Crypto Watchers Should Monitor Next
The next question is whether Starknet’s lead in GitHub-based development activity turns into more visible execution, such as new apps, stronger user retention, and higher on-chain usage. Development momentum and realized adoption are related, but they are not the same metric.
Aztec’s second-place finish in Santiment’s latest ranking is another signal worth watching because it suggests the ZK side of the Layer 2 market is attracting meaningful builder attention at the same time Starknet is leading.
Arbitrum, zkSync, and Optimism remain important competitors even after slipping behind in the March 5 development snapshot. A single ranking can show where builders are concentrating now, but it cannot settle the race before user growth, liquidity depth, and product launches catch up.
Policy remains a background variable rather than the center of this story, yet compliance standards can still shape who builds where over time. That is why pieces like the FCA’s latest crypto guidance consultation matter for readers tracking which Ethereum-aligned networks may look most credible to institutional teams in the next phase of adoption.
For now, the cleanest takeaway from Santiment’s latest Layer 2 ranking and DefiLlama’s view of Ethereum’s capital base is that Starknet has the freshest developer lead in a market where scale still commands outsized attention, and the projects behind it will need to prove that code velocity can become durable usage.
