The Top Ethereum Layer 2 Contenders of 2025

As Ethereum Layer 2 solutions continue to expand, one big question looms: which platforms will dominate 2025? According to analysts at investment firm VanEck, Ethereum’s Layer 2 scaling networks could achieve a combined market cap of $1 trillion within the next six years, fueled by the emergence of thousands of chains tailored to specific use cases.

As 2024 draws to a close, it’s the perfect time to examine who’s leading the race and what sets them apart. Currently, three Layer 2 platforms—Arbitrum, Base, and Optimism—are at the forefront, competing for billions in total value locked (TVL) and the loyalty of developers and users alike.

*Total Value Locked (TVL) refers to the amount of assets staked or locked in DeFi protocols on a network. It serves as a measure of how much capital is being used and secured on the platform, an indicator of both user trust and network activity.

This updated chart from DeFiLlama shows the TVL for the top three Ethereum Layer 2 blockchain networks: Arbitrum, Base, and Optimism, as of October 13, 2024. Here are the key insights:

• Arbitrum (Green): $2.385 billion USD
• Base (Pink): $2.368 billion USD
• Optimism (Blue): $664.63 million USD

‍

Overview of Chains:

1. Base has rapidly gained traction since its launch in mid-2023. It started at a low TVL, saw a significant spike, and as of late 2024, it is nearing parity with Arbitrum, just shy of overtaking it in terms of TVL.
2. Arbitrum continues to dominate with the highest TVL among the three. Its TVL reached a peak around mid-2023 and has been generally stable since, showing slight fluctuations but maintaining a leading position.‍
3. Optimism shows a less impressive performance relative to the other two chains. After peaking in 2022, it experienced a steady decline, dropping to around $664 million in 2024. It seems to be trailing behind the rapid growth of both Arbitrum and Base, indicating it might be facing challenges in maintaining or growing its TVL.

‍

Insights:

• Arbitrum and Base are the leading contenders, with their TVL values nearly equal in late 2024. This suggests that Base has quickly captured a significant market share, possibly due to its strong adoption and DeFi activity.
• Optimism's relatively low TVL, despite its early advantage in 2022, suggests a decline in its competitive position. This could be due to various factors like competition from newer Layer 2 solutions, market dynamics, or other protocol-level issues.

By October 2024, the competitive landscape for Layer 2 solutions and Ethereum-compatible chains shows that Arbitrum and Base are neck and neck in terms of TVL, signaling strong user engagement and DeFi activity. Optimism, once a leader, has fallen behind in terms of TVL, which could indicate a shift in user preferences or technology advantages favoring its competitors. The close competition between Arbitrum and Base will be something to watch moving forward.

Arbitrum vs Base

As of October 2024, Arbitrum and Base are in direct competition, with both chains maintaining similar TVL figures. This close proximity in TVL highlights the rapid rise of Base and the sustained strength of Arbitrum, despite their different launch timelines and strategies.

Arbitrum: The Early Leader

Arbitrum was an early player in the Layer 2 space, launching in mid-2021 as one of the first optimistic rollup solutions aimed at improving Ethereum’s scalability. It has consistently ranked among the top Layer 2 solutions, benefiting from the early mover advantage and securing a strong user base through its robust ecosystem of DeFi projects.

Key factors driving Arbitrum’s growth include:

1. Deep DeFi Integration: Arbitrum attracted a significant portion of DeFi projects, offering users lower gas fees and faster transactions compared to Ethereum mainnet, without compromising security. Major DeFi protocols like Uniswap, Curve, and Aave have all integrated with Arbitrum, contributing to its high TVL.
2. Ecosystem Maturity: With over three years in operation, Arbitrum has built a mature ecosystem with top tier builders and users.
3. Technological Stability: Arbitrum’s optimistic rollup technology, while not the newest on the block, has proven to be stable, secure, and scalable, which has earned it trust within the community.

However, Arbitrum’s TVL growth, while impressive, has been relatively stable in recent months. As competition intensifies, particularly from newer entrants like Base, maintaining its lead will depend on continued innovation, strategic partnerships, and retaining its strong developer community.

Base: The Rapid Riser

Base, a relative newcomer, launched in mid-2023 as a Layer 2 solution incubated by Coinbase, one of the largest cryptocurrency exchanges in the world. Despite its recent entry, Base has quickly captured market share and now sits just behind Arbitrum in terms of TVL.

Base’s rapid rise can be attributed to several factors:

1. Strong Institutional Backing: Being backed by Coinbase has given Base a significant advantage in terms of trust, visibility, and integration with a wide user base. Coinbase’s vast network of users and institutional clients has provided Base with a ready-made audience for growth.
2. Early Adoption of Key Protocols: Base’s launch strategy included partnerships with key DeFi protocols and NFT platforms. By securing integrations with established projects and offering incentives for users to bridge over to Base, it was able to rapidly accumulate TVL.
3. Focus on User Experience: Base has focused heavily on improving the user experience by providing fast, cheap transactions and integrating tightly with the Coinbase ecosystem. This seamless experience has likely attracted retail users who are more familiar with centralized exchanges but are interested in decentralized applications.

One of Base’s key differentiators is its Coinbase connection. As a Layer 2 solution built by such a large entity, it has a built-in trust factor that smaller, decentralized Layer 2 chains must work harder to achieve. Additionally, Base’s emphasis on bridging centralized and decentralized worlds has made it an attractive option for newcomers to the crypto space, providing a simpler onboarding experience compared to other Layer 2 solutions.

The Race: Who Will Win?

The competition between Arbitrum and Base is heating up, and both networks have strong claims to their positions as leading Layer 2 solutions. Here’s a deeper dive into the potential challenges and opportunities that each network faces:

• Arbitrum:
  • Opportunities: Arbitrum’s established ecosystem and developer base give it a strong advantage. If it can continue to innovate, integrate newer DeFi protocols, and expand into adjacent spaces like gaming and NFTs, it could maintain or even grow its lead.
  • Challenges: Arbitrum’s slower growth in TVL recently suggests that it might be facing saturation in its core DeFi market. To stay competitive, it will need to differentiate further, potentially by offering new types of rollups, zk-rollups, or integrating more sophisticated cross-chain interoperability solutions.
• Base:
  • Opportunities: Base’s tight integration with Coinbase offers a direct line to millions of users who may not yet be active in the decentralized ecosystem. This captive audience gives Base a unique advantage in onboarding new users and driving TVL. As DeFi continues to grow, Base is well-positioned to capitalize on its strategic partnerships.
  • Challenges: Despite its rapid rise, Base is still a new player in the space. Long-term success will depend on how well it can retain users, develop a strong ecosystem, and continue to innovate. As Layer 2 competition intensifies, Base will need to prove its independence and not rely solely on Coinbase’s network for growth.

The Battle for Dominance: Dapps, Wallets, and User Experience

While TVL is often seen as the main indicator of success in the Layer 2 space, the reality is that it’s just one part of the equation. As Arbitrum and Base continue their fierce competition, the deciding factor in which network ultimately wins the Layer 2 race may have less to do with TVL and more to do with the experience they offer users and developers. Dapps (decentralized applications), wallet integrations, and overall user experience (UX) will be critical to driving both user acquisition and long-term retention.

In the end, user experience will be king, and the network that makes it easiest for users to onboard, transact, and explore the decentralized world will come out on top.
