Layer2 mid-year review: Base surpasses Optimism to become the second largest Layer2; zkSync and Satrknet face ecological difficulties

Original title: "Layer2 track mid-year review: Is the growth data true or false? "

Original author: Linda Bell, ChainFeeds

In March 2024, Ethereum completed the Cancun upgrade, bringing attention back to the Layer2 field. At the same time, Starknet and zkSync completed the airdrop plan in the first half of the year, and the four major Layer2 projects have issued tokens. In addition, some new Layer2 projects also performed very well in 2024. For example, Base achieved significant traffic growth in the first half of 2024, surpassing Optimism to become the second largest Layer2.

Although the Layer2 field shows a strong growth trend, the market still has doubts about the authenticity of its data. Previously, zkSync's average daily transaction volume and number of active addresses have been questioned. So, do these superficial prosperity truly reflect the actual use of the network?

TL;DR:

· In the first half of 2024, Arbitrum continued to lead, with a total locked value of $17.15 billion, accounting for 40% of the market share, ranking first.

· Base surpassed Optimism with a TVL of $7 billion to become the second largest Layer2 platform. In addition, as of July 28, Base's average daily transaction volume reached 4 million, almost twice that of Arbitrum, and the number of active addresses also exceeded Arbitrum, reaching more than 600,000.

· zkSync's TVL reached $1.12 billion in the first half of 2024, up about 99% from the beginning of the year, but the number of active addresses fell by 83.5% after the airdrop, and the average daily transaction volume also fell by 86%. Similarly, Starknet’s TVL fell back to $685 million after reaching an all-time high of $1.776 billion in March, with the number of active addresses falling 92% and average daily transaction volume falling 64.2%.

· Taiko, which launched its mainnet in May 2024, reached an all-time high of $190 million on June 5, but then fell back to $163.45 million. The number of active addresses fell 78.3% from the June peak.

· Scroll TVL increased by 1544% last year, but the growth of its active addresses and average daily trading volume was relatively small. The number of active addresses increased by 13.4% from the beginning of the year, and the average daily trading volume increased by 27.7%.

Total locked value

Arbitrum leads, Base surpasses Optimism to become the second largest Layer2

In the first half of 2024, the total locked value of the Layer2 ecosystem increased from about US$22.8 billion at the end of January to US$42.97 billion, an increase of about 88%. Among them, Arbitrum, Optimism and Base are the main contributors.

Since the beginning of 2024, Arbitrum's total locked value has remained at the leading level. As of July 28, Arbitrum's TVL reached approximately US$17.15 billion, ranking first, accounting for approximately 40% of the market share, far exceeding the second-ranked Base by more than 2.4 times. According to DeFiLlama data, the project with the highest total locked value on Arbitrum is AAVE, with a locked value of US$812.62 million, followed by GMX and Uniswap, with US$513.89 million and US$325.43 million, respectively.

In addition, as can be seen from the figure below, Arbitrum's total locked value showed a downward trend from March to May, mainly because the Arbitrum team and investors unlocked a large number of ARB tokens in March. According to Token Unlocks data, as of July 28, the unlocking progress of ARB is temporarily 34%.

As a rising star, Base has maintained an upward trend since the beginning of 2024, and surpassed Optimism in June to become the second largest Layer2. At present, the total locked value of Base is about 7 billion US dollars, an increase of about 716% from the beginning of the year. As can be seen from the figure below, Base saw a significant increase in TVL in March, which may be due to the continued growth of Farcaster, the reduction of gas fees after the Cancun upgrade, and the popularity of MEME tokens, which led to a significant increase in on-chain liquidity and promoted the growth of TVL. However, Base's TVL has fallen slightly at present, down about 6.6% from June.

According to DefiLlama data, the current DeFi TVL on Base is $1.67 billion, of which native DeFi projects dominate, including Aerodrome ($654 million) and Extra Finance ($110 million). Aerodrome is the dApp with the highest total locked value on the Base chain, more than double the second-ranked Uniswap.

Optimsim currently ranks third in total locked value. It reached its historical high in the first half of the year on March 10, 2024, and then fell slightly, but was generally stable, and was eventually overtaken by Base in June. According to DeFiLlama data, the top three projects in the Optimism ecosystem TVL are AAVE v3, Synthetix and Velodrome. However, in the past month, the TVL of these projects has shown a downward trend.

Scroll hits new highs, Taiko TVL falls after reaching a historical high

On the other hand, Scroll's total locked value in 2024 has hit new highs, currently reaching $1.3 billion, ranking fourth among the Layer2 selected in this article, with an astonishing increase of 1544%. This growth may be attributed to a series of activities launched by Scroll at the user and developer level. Scroll launched Scroll Sessions in April and launched Session One on June 21, aiming to specifically reward DeFi users who provide liquidity in DEX. In addition, Scroll has launched the "Level Up with Scroll" platform, allowing developers to apply for ecological funding.

According to DeFiLlama data, the project with the highest total locked value on Scroll is its native project Pencils Protocol, with a locked value of US$310.87 million, an increase of 317% in the past month. It is worth noting that Scroll DeFi's total locked value is US$769.02 million, and the total locked value of the top three projects in its ecosystem accounts for more than 95% of the market share.

Taiko was launched on the mainnet on May 27, 2024. As shown in the figure below, Taiko TVL reached a historical high of about US$190 million on June 5, and has now fallen back to US$163.45 million. As a newly launched Layer2 on the mainnet, Taiko TVL is lower than other well-known Layer2s, but it is actively expanding its ecosystem. For example, in terms of DeFi applications, Taiko has integrated more than 80 projects such as LayerZero, Stargate, and Oku Trade.

According to DeFiLlama data, the top three projects in terms of total locked value of Taiko are DTX, a decentralized perpetual trading platform, iZUMi Finance's multi-chain DEX platform iZiSwap, and Uniswap V3. Overall, the TVL of Taiko ecosystem projects is not high, and DTX occupies a relatively significant market share.

zkSync and Satrknet are facing ecological difficulties, and the locked value has decreased after the airdrop

As of now, the total locked value of zkSync is US$1.12 billion, up about 99% from the beginning of the year. As can be seen from the figure below, zkSync's TVL has seen significant growth in June, mainly due to its airdrop plan announced on June 11. According to the plan, zkSync airdropped 3.6 billion tokens to community members on June 17, with a total of 695,232 eligible wallet addresses. However, Nansen data shows that after the zkSync airdrop, more than 40% of the main recipients sold all of their allocated tokens, and 41.4% sold part of their allocated tokens. Only 17.9% still hold tokens.

In addition, although the zkSync ecosystem has integrated more than 200 projects, only 2 projects have a TVL of more than 10 million US dollars according to the data. The project ranked first in TVL is SyncSwap, with a TVL of 35.17 million US dollars, which is the absolute leader. In addition, the TVL of the top three projects, SyncSwap, Koi Finance, and zkSwap Finance, have all declined in the past month. Overall, for zkSync, the effect of the airdrop is just the beginning, and ecological issues and sustainable development issues are what it needs to focus on.

Similarly, in the first half of 2024, Starknet's total locked value began to rise significantly on February 20 and reached an all-time high of $1.776 billion on March 14. This growth was mainly driven by the STRK token airdrop plan and the "Starknet Spring DeFi Incentive Program" launched by the Starknet Foundation. However, as of now, Starknet's TVL has fallen back to about $685 million, down about 61% from its peak.

In terms of ecological progress, the Starknet ecosystem has currently integrated more than 100 applications. The top five projects in terms of total locked value on Starknet are all Starknet native projects. The first place is the lending protocol Nostra, with a locked value of $164.6 million; the second place is the decentralized exchange Ekubo, with a TVL increase of 61.95% in the past month. It is currently $77.98 million; the third place is the lending protocol zkLend, with a TVL of $26.7 million. However, there are only four projects in the Starknet ecosystem with a TVL of more than 10 million US dollars, and the fifth-ranked lending protocol Vesu has a TVL of only 3.77 million US dollars.

Number of active addresses and number of transactions

In addition to TVL, the number of active addresses and average daily transaction volume of the network can reflect the actual use of the network and user participation. In the first half of 2024, Arbitrum and Base had high user activity, while zkSync and Starknet showed a clear downward trend. Optimism and Scroll showed solid growth, albeit relatively small.

Arbitrum Active Addresses Surge 140.7%, Base Daily Transaction Volume Exceeds 4 Million

Since the beginning of 2024, Arbitrum active addresses have increased by 140.7%. This growth is due to the large-scale subsidy and funding support strategy implemented by Arbitrum. For example, the Arbitrum community passed a proposal in June to provide Arbitrum ecological games with a total of 200 million ARBs for three years and set aside $25 million for project management and operations. In addition, the Arbitrum Foundation provided financial support to 13 projects including DODO and Double in May. However, Arbitrum's average daily transaction volume has only increased by 43.7% from the beginning of the year, which is less than the increase in the number of active addresses. This may be due to a large number of new users creating addresses but not frequently trading, or mainly low-frequency trading activities.

Currently, Base's average daily transaction count and number of active addresses are both higher than Arbitrum. As can be seen from the figure below, at the beginning of 2024, Base's daily transaction count was only 330,000, while Arbitrum's was about 1 million. Since March 2024, Base's daily transaction volume has begun to rise significantly, and hit a new high on June 27. As of July 22, Base's daily transaction count reached more than 4 million, almost twice that of Arbitrum. At the same time, Base's number of active addresses is also rising, and now exceeds Arbitrum, reaching more than 600,000. In addition to the influence of Meme Coin and SocialFi, the Smart Wallet launched by Coinbase has also played an important role in improving user experience and transaction volume. The Smart Wallet provides a simplified, gas-free on-chain experience, enabling users to create a free, secure, self-hosted wallet in seconds, significantly improving the convenience of users' transactions.

The number of active addresses and daily average transactions of zkSync and Starknet have both declined significantly

In the first half of 2024, the number of active addresses and daily transactions in the zkSync ecosystem have both declined significantly. At the beginning of the year, zkSync ranked first in the number of active addresses, but then gradually declined. As can be seen in the figure below, the number of active addresses on the network has decreased by about 83.5% within one month after the zkSync airdrop on June 17, 2024. This shows that most users are just to get the airdrop. In addition, the average daily transaction volume of zkSync has also begun to decline since the beginning of the year, and is currently down about 86% from the beginning of the year. Similar to the number of active addresses, the average daily transaction volume has declined significantly within one month after the airdrop.

On July 2, zkSync announced the launch of zkSync 3.0 Elastic Chain, an infinitely scalable ZK Rollup network. zkSync said that this solution achieves native, trustless, and low-cost interoperability between ZK chains. However, whether it can seize the market share of Optimism's Superchain and Polygon's AggLayer in the market still needs time to verify.

Similar to zkSync, Starknet's average daily transaction volume and number of active addresses have also declined in the first half of 2024. So far, Starknet's average daily transaction volume has dropped by about 64.2% from the beginning of the year, while the number of active addresses has dropped by about 92% from the beginning of the year. Among the several Layer2 solutions selected in this article, Starknet's daily transaction volume and number of active addresses are both ranked last. As can be seen from the figure, Starknet's number of active addresses and daily transaction volume had a small increase at the beginning of the year, mainly due to the airdrop plan in February, but after the airdrop, its number of active addresses and daily transaction volume began to gradually decline. In the future, Starknet also plans to airdrop about $400 million in STRK tokens.

However, Starknet has several updates planned for the second half of the year. The Starknet community released v0.13.2 and a summer roadmap update, with v0.13.2 expected to be released in August and v0.13.3 between October and November. At the recent ETHCC summit in Brussels, Eli Ben-Sasson also announced that Starknet will be open for staking by the end of 2024.

Optimism and Scroll grew steadily, with active addresses up 35% and 13.4% respectively

Optimism had a relatively stable development in the first half of 2024. The average daily transaction count and the number of active addresses have increased slightly from the beginning of the year, with the number of active addresses up 35% and the average daily transaction count up 14%. As can be seen in the figure below, Optimism's number of active addresses and average daily transaction count have small peak fluctuations, which may be related to specific developments or market activities. For example, Optimism announced in May that L3 built with OP Stack can now join the super chain and is eligible for Retro funding, airdrops, and growth activities. In addition, Optimism's Retro Funding has been distributed in four rounds since May, with a total of 850 million OPs allocated to fund projects or people in the ecosystem. These activities and incentives may have contributed to the growth in the number of active addresses.

In the first half of 2024, Scroll's number of active addresses increased by 13.4% from the beginning of the year, and the average daily transaction volume increased by 27.7%. Unlike Scroll TVL, its number of active addresses and average daily trading volume did not increase much.

After Taiko mainnet went online, the number of active addresses dropped by 78.3% from the peak value

As can be seen from the figure below, the number of Taiko's active addresses rose sharply between June 4 and 5, and then began to fall back. The main reason may be that the TAIKO token was launched on the Bitget exchange on June 5. Since then, the number of active addresses has fallen back, and after a slight increase on June 11, it fell back again. It is currently about 40,000, a decrease of 78.3% from the peak value. In addition, Taiko's average daily trading volume reached a historical high on June 30, and is currently 1.35 million transactions, a decrease of about 38.4% from the high point.

In addition, after the mainnet was launched, some community members said that Taiko is more expensive than other L2 protocols on Ethereum. In response, Taiko said that this is mainly because it involves more logic and storage. The current implementation uses multiple upgradeable agents, which adds additional delegate call costs. And Taiko's blocks are not proposed or proven in batches, and proposers need to interact with Ethereum more frequently to compete for block space and ensure on-chain activity. Since the on-chain ring buffer has not been exhausted, the storage write cost is also high. Taiko said that this situation will improve in about 40 to 60 days. It is worth noting that the Taiko mainnet has been successfully upgraded to version v1.7.0 on July 2, which is expected to significantly reduce the Gas usage of the Rollup protocol on Ethereum.

Summary

Overall, both old and new Layer2 projects showed a diversified development trend in the first half of 2024. However, there are also some problems in this field. For example, zkSync and Starknet saw a decline in user engagement after the airdrop, reflecting an over-reliance on short-term incentives. Although Scroll and Taiko have seen significant growth in TVL, they have encountered challenges in maintaining user activity and require more comprehensive ecological development. This also means that as the market continues to evolve, major Layer2 projects still need to continue to innovate and expand to ensure sustainable growth and user engagement.
