From “Speed and Cost” to “Revenue and Retention”: A Paradigm Shift in the Competitive Logic of Layer 2

After several years of technical iterations, the Ethereum Layer2 sector is moving into a brand-new competitive phase. Over the past two years, industry discussion has consistently centered on two core metrics—transaction throughput and Gas fees. The debate over the technical paths of OP-Rollup versus ZK-Rollup, along with expectations that EIP-4844 will optimize Gas fees, has formed the mainstream framework of the Layer2 narrative.

However, as the gaps at the technical level gradually narrow, the logic of market competition is undergoing a fundamental shift. According to L2BEAT data, as of July 2026, Ethereum Layer2’s total value locked has rebounded to nearly $45 billion. Among them, Arbitrum One leads with approximately $17.73 billion in TVL, Base is about $7.33 billion, OP Mainnet is about $6.04 billion, and Blast’s TVL is about $2.65 billion. The “winner-takes-most” effect is extremely pronounced—Base, Arbitrum, and Optimism combined account for close to 90% of Layer2 transaction volume.

In such a highly concentrated market landscape, a new entrant can’t break through by relying on “faster and cheaper” alone. Blast’s answer is to make asset yield the core competitive advantage of a Layer2, rather than a peripheral feature.

The “yield vacuum” of traditional Layer2: an overlooked structural problem

Before Blast emerged, Layer2 networks generally suffered from a structural blind spot in their design: once users bridge assets to Layer2, those assets enter a “yield vacuum” state.

Ethereum mainnet ETH holders can earn roughly a 3% - 4% annualized return through staking. But once users bridge ETH cross-chain to popular Layer2s like Arbitrum and Optimism, they lose the ability for those assets to earn interest on the mainnet. Stablecoins are similar—while on the mainnet users can earn through various DeFi protocols, on Layer2 the default interest rate is 0%.

This means that each time a user moves an asset from the Ethereum mainnet to Layer2, they incur a “lost yield” cost. In a bull market, this opportunity cost may be offset by trading frequency and airdrop expectations; but during periods of market volatility or sideways movement, the non-yield state of assets significantly weakens users’ willingness to remain long-term.

In an analysis, PANews pointed out that the Layer2 industry has long faced an awkward situation of “grand technical narratives but poor ecological execution.” The three pillars of pure-finance applications—DEXs, lending, and derivatives—cannot independently support sustained Layer2 ecosystem growth. Layer2 needs to attract not only the existing large financial players from the mainnet, but also long-tail users who are sensitive to Gas fees and sensitive to user experience barriers.

Blast’s core insight lies here: if Layer2 cannot solve the “yield vacuum” problem of assets, then even if transactions are faster and Gas fees lower, it will be difficult to build true user stickiness.

Blast’s native yield mechanism: an automatic yield logic built on a three-layer architecture

Blast’s native yield model is built on a three-layer architecture, with each layer having a clear source of yield and an allocation path.

First layer: ETH staking yield. When users bridge ETH to Blast, Blast locks the corresponding ETH on Layer 1 for native network staking, mainly by interacting with staking protocols such as Lido. These staking rewards are returned directly to users on Blast via an auto-rebasing mechanism. Users don’t need to actively participate in staking; holding ETH alone yields about 4% annualized.

Second layer: stablecoin RWA yield. For stablecoins (such as USDC, USDT, and DAI), Blast locks the corresponding stablecoins on Layer 1 and deposits them into RWA protocols like MakerDAO that invest in US Treasury bills. The returns are automatically returned to users in the form of USDB (Blast’s native stablecoin), with a stablecoin yield rate of about 5%. Some market data indicates that stablecoin yield rates can reach 8% in certain periods.

Third layer: Gas fee revenue sharing. Blast uses programming to return a portion of the network’s net Gas income to the DApps built on it. This mechanism provides developers with an additional income source, creating a positive loop of “users earn yield—developers benefit—ecosystem thrives.”

A common feature of these three yield layers is “automation” and “frictionlessness.” Users don’t need to learn complex staking operations or incur additional smart-contract interaction costs. Once assets enter the Blast network, they begin earning yield automatically. This “default yield” design is fundamentally different from other Layer2s’ “default no-yield.”

Ecosystem growth driven by dual engines: the BIG BANG plan and developer incentives

Blast’s ecosystem growth strategy can be summarized as “dual-engine driving”: on one hand, it introduces a large number of high-quality projects through the BIG BANG plan; on the other hand, it retains developers through Gas fee sharing and airdrop-style incentives.

On January 17, 2026, Blast officially announced the BIG BANG event. The plan’s core design includes: 50% of the airdrop pool funds allocated to winning projects, and the remaining 50% allocated to participating users who interact. Evaluation criteria cover eight categories: perpetual contract DEXs, spot exchanges, lending protocols, NFTs and games, SocialFi, GambleFi, infrastructure, and innovative projects that use Blast’s native yield or Gas fee-sharing mechanisms. On the first day of the testnet alone, it attracted 24,587 participating addresses, and to date there are more than 100k active addresses participating.

From the data, this strategy shows strong effects in the short term. Within two days of launching, Blast’s TVL reached $100 million, and after 34 days it surpassed $1 billion. As of May 2026, Blast’s total value locked in DApps exceeded $2 billion, making it the sixth-largest on-chain economic system globally.

However, the sustainability of ecosystem growth is always the focus of market attention. Some analysis suggests that in Blast’s ecosystem, over 90% of the protocols lose appeal or become inactive after the initial hype fades. This phenomenon reveals the core dilemma of incentive-driven growth: cold starts can be powered by yield, but long-term retention must be driven by real demand.

The real test of user retention: the liquidity game after deposits become fully withdrawable

In June 2026, Blast officially opened full withdrawal functionality for bridging, marking the network’s transition from a “one-way deposit” phase to a fully operational “two-way circulation” phase. This was the first true stress test of Blast’s user retention capability.

Before that, Blast adopted a “forced retention” model—once users deposited assets, they couldn’t withdraw immediately, and liquidity was locked inside the network. This design is effective at preventing liquidity outflow during cold-start stages, but it also means early TVL data doesn’t truly reflect users’ voluntary willingness to stay.

After bridging opened, the key question observers care about is: how much capital will continue to remain in the Blast ecosystem, and how much will flow to competing Layer2s or back to the Ethereum mainnet?

Based on June 2026 data, Blast’s TVL fell 62% from its historical peak, and its daily active users dropped to the lowest level in six months. In early August, the network lost more than $300 million in liquidity; TVL dropped from $1.1 billion to $785 million. By comparison, Base and Arbitrum’s daily active wallets were both above 740k and 360k respectively.

These figures indicate that Blast still faces significant challenges in user retention. After airdrop expectations faded, some users chose to leave—this behavior pattern is not fundamentally different from almost all past crypto projects that relied on incentives to kickstart growth.

Risks and challenges: multisig control, ecosystem concentration, and long-term sustainability

Blast’s development path has not been without controversy. From the technical architecture perspective, Blast uses an Optimistic Rollup solution based on OP Stack. However, its contracts are controlled by a 3/5 multisig, and all five addresses are anonymous newly created addresses, which means the multisig parties theoretically have the potential ability to influence users’ funds through code upgrades. This architecture arrangement has led some developers to raise concerns about security.

From the standpoint of market competition, the Layer2 sector is undergoing a “major cleanup.” The top five Layer2s—Base, Arbitrum, Optimism, zkSync, and Starknet—have already captured over 85% of market share, while the remaining dozens of Layer2s average TVL of less than $50 million. A 21Shares analysis points out that more than 50 Layer2s are competing for users, liquidity, and developers, but by the end of 2025 the market had become highly concentrated among the three networks: Base, Arbitrum, and Optimism.

Whether Blast can maintain an independent position in this round of consolidation depends on three key variables: first, whether the native yield mechanism can remain attractive amid volatility in both ETH staking yields and RWA yields; second, whether the projects introduced via the BIG BANG plan can shift from incentive-driven to product-driven, generating real user demand; third, whether the developer ecosystem can break away from reliance on a single yield model and form diversified application scenarios.

Conclusion

Blast’s emergence marks a transition in Layer2 competition from a “technical metrics contest” to a new phase of “user experience and asset utility competition.” Traditional Layer2s solved issues related to transaction speed and Gas costs, but they didn’t answer a more fundamental question: besides trading, what else can users’ assets do on Layer2?

Blast offers a differentiated answer through its native yield mechanism—letting assets keep earning while waiting to be used for transactions. This mechanism effectively drove rapid TVL growth in the short term, but long-term success depends on whether early incentive enthusiasm can be transformed into sustainable ecosystem vitality.

As one analyst put it: “A cold start can be powered by yield, but long-term retention must come from real demand.” Blast has already completed the cold start from 0 to 1. The next thing it needs to answer is the proposition from 1 to N—which is the ultimate test faced by all Layer2 projects.

FAQ

Q1: How does Blast’s native yield work?

Blast uses the ETH bridged by users for staking on the Ethereum mainnet (such as Lido), and deposits stablecoins into RWA protocols like MakerDAO. The obtained rewards are returned directly to users through an auto-rebasing mechanism. ETH annualized yield is about 4%, stablecoin yield is about 5%, and users don’t need any additional actions.

Q2: What is the core difference between Blast and other Layer2s?

Traditional Layer2s focus on improving transaction speed and lowering Gas fees, and users’ assets default to having no yield while on-chain. Blast is the only Layer2 that provides native yield for both ETH and stablecoins. Once assets are bridged, they automatically start earning yield, while also retaining EVM compatibility and low transaction fees.

Q3: Why did Blast’s TVL fall after withdrawals were opened?

Before June 2026, Blast used a “forced retention” model, preventing users from withdrawing. After withdrawals were opened, some users chose to leave, which is a normal adjustment after incentives fade. As of July 2026, Blast TVL is about $2.65 billion and still ranks among the top Layer2s.

Q4: How sustainable is Blast’s ecosystem long-term?

Blast’s long-term development depends on three factors: whether the yield mechanism can remain attractive despite fluctuations in yield rates, whether the projects introduced by the BIG BANG plan can shift from incentive-driven to product-driven, and whether the developer ecosystem can form diversified application scenarios. Currently, in the ecosystem, active levels drop for over 90% of the protocols after the initial hype fades.

Q5: What risks does Blast have?

Main risks include: the contracts are controlled by a 3/5 anonymous multisig, creating potential centralization risks; the Layer2 sector is highly concentrated, with the top three networks accounting for nearly 90% of transaction volume; and user retention faces challenges after airdrop incentives fade.
