Ethereum makes rollup transactions cheaper by providing a lower-cost data space. The savings in costs benefit users and applications, but it also makes it more difficult for smaller chains to generate sufficient revenue from transaction fees to support sorters, bridges, security efforts, and developers. Two announcements of closures in October turned this balance from theoretical into a practical issue, with a deadline for withdrawals.

• On October 2, Blast stated that the cost of maintaining its Layer 2 exceeded the income it generated, and requested users to use their regular withdrawal interface by October 26.
• The consumer chain Abstract related to Pudgy Penguins is also planned to stop operating on December 15th. Prior to this, its operator claimed to have incurred losses due to online financing activities.
• As of around October 6th, as displayed by L2BEAT, approximately $43.56 billion in value from the tracked projects was secured, of which Base and Arbitrum One accounted for a large portion.
• Cheap Ethereum blobs will reduce the on-chain costs of rollup, but it will not cover the expenses for off-chain operations, incentives, application development, or user support.
• On-chain fees, application revenue, total locked value, and token market capitalization describe different aspects of a business; looking at any one of these alone does not prove that the operator is making a profit.

The operator of Blast informed users to transfer their funds to the Ethereum mainnet, including the balances in their web applications, as they determined that operational expenses had exceeded Layer times the income. A report on October 2nd stated that during the team's liquidation of Lido assets, regular withdrawals might be temporarily suspended and then resumed, but the delay would be reduced to 24 hours. The regular interface was expected to remain in place until October 26th; the team indicated that after that, assets could still be withdrawn by interacting directly with the bridge contract on Ethereum. The difference between a fully functional bridge contract and an easy-to-use interface is significant for users.

On October 7th, CoinDesk reported that Abstract plans to shut down on December 15th; previously, Igloo stated that they had incurred losses of tens of millions of dollars while financing the chain. According to this report, over 325 million transactions and millions of wallet interactions have not been transformed into a sustainable network business. What is mentioned here is the opinion of the operators, not audited income and cost statements. The products of these two chains are different, but both have exposed a gap between visible activity and long-term operation with financial support.

rollup How to make money?

Many Layer 2 operators run a sorter responsible for sorting transactions and charge users a gas fee. The chain needs to pay Ethereum for data availability and transaction settlement fees, pay infrastructure providers, and may also have to pay commissions to the technology stack or partners. It can subsidize user fees or distribute some of the profits to applications. Other potential revenues come from enterprise services, application ownership, transaction sorting, or licensing. In each chain, the economic ownership of these revenue streams varies.

For illustrative purposes, the cost calculation starts with the amount paid by users to the blockchain. From this amount, the costs incurred for publishing and verifying content on Ethereum are deducted, followed by expenses for router hosting, engineering, security, legal services, customer support, incentives, and any distribution agreements. Many public dashboards only display the first deduction. The result obtained is the gross profit margin, not the audited net profit. A growing network may intentionally incur losses in order to attract applications and liquidity; however, a smaller network needs a credible path to cover its ongoing costs.

The Blast income page for DefiLlama will list a separate item for each chain, which is defined as the gas fee minus the Layer batch cost, as well as the income generated from applications on Blast. The interest margin of a lending application belongs to that application or its stakeholders, unless there is a different profit-sharing contract in place. It is incorrect to sum up the income from all applications and consider it as the company income of Blast. The values displayed on this dashboard also change daily, and different protocols may use different definitions.

The Abstract page for DefiLlama illustrates the same trick: a certain application can charge very high fees, while the fee for using the network itself is much lower. The well-known consumer applications from Abstract may have generated some commercial activity, but it has not been sufficient to generate enough revenue to allow Igloo to maintain its own independent blockchain. Neither tokens, brand partnerships, nor high transaction volumes can automatically make up for this shortfall.

Why has the cheaper blobs changed its business model?

EIP-4844 has created an independent market for rollup data blobs. There's no need to release each batch as an expensive and permanent calldata; instead, compressed data can be released in blob at a lower cost. Ethereum's rollup documentation explains that this cost is merely a portion of the Layer user fees. The original intention of this design was to provide cheaper transactions and greater capacity, rather than to guarantee high profit margins for every chain operator.

If operators maintain unchanged user fees, lower on-chain costs can improve their gross margins. However, competition usually passes on the savings to users. When many similar networks offer low-cost execution, it is difficult for new networks to charge higher fees in the absence of exclusive applications, distribution channels, or strong liquidity. Their fixed operating costs still exist, yet each ordinary transaction contributes very little revenue. At low transaction volumes, the problem is not just the cost associated with Ethereum, but whether there are enough paid activities to cover the entire business.

The research on Ethereum Robust Incentives Group versus EIP-4844 also describes another trade-off related to low trading volumes. The publishing cost of a blob is unrelated to how much of its capacity is filled; waiting for a fuller batch can reduce the cost per transaction, but it will increase latency. Frequent publishing for a smoother user experience will result in excess blob capacity being used. This means that even if the average blob price is very low, the chain may still face real economic choices to make.

If the space requirements for blob increase, data costs may rise again, and the security and availability of rollup also depend on its design. Some networks use external data availability arrangements, therefore assuming different levels of trust and having different cost structures. Just because both projects promote themselves as being Layer 2, it cannot be inferred that their payment or exit rights regarding Ethereum are exactly the same. The risk and cost profiles of L2BEAT will differ from those of other designs, and the protected value will be tracked separately from the financial performance of the operators.

The activities are focused on the places where users are already located.

A snapshot at the beginning of October shows that the total protected value is approximately $43.56 billion, of which Base is about $16.24 billion, and Arbitrum One is about $11.42 billion. These figures are sensitive to the market and include assets under different bridging arrangements. They represent scale and concentration, rather than income statements. A stablecoin balance of $1 billion held on the chain that remains largely unchanged may generate very little gas income; whereas a much smaller-scale asset that is frequently traded might actually incur higher fees.

Large networks are able to attract more applications because users and liquidity are already present there. Developers need to pay integration costs to support another chain, exchanges must manage deposits and risks, and bridges must maintain liquidity. New chains may use subsidies and token rewards to establish these connections. Once the incentives decline, operators will see which uses are truly self-sustaining. This is the financial aspect of fragmentation: each chain repeats some of the operations, while the most liquid destinations will reap the network effects.

crypto.news Reports on the exit of Syndicate Labs describe another layer of pressure being exerted on rollup infrastructure companies: as the number of new chains decreases and it becomes harder to maintain the activity of existing chains, these companies are also contracting. That is the business of suppliers, which is not equivalent to the economic model of sorters, but their customers face the same problem: with each additional chain added, is there really a sustained enough demand?

Of course, there are also examples that are contrary to the general trend of decline. If an operator has direct distribution channels, sustained application usage, and valuable reasons for controlling rankings, it may achieve a significant gross margin difference. The analysis of costs between crypto.news and Robinhood Chain mentioned a day with high fees, yet the cost of sending transactions to Ethereum was very low. However, it also warns that the total difference does not equate to profit, and the activities on that day cannot be directly annualized. The peak in fees may be automated or merely temporary. The true, lasting measure of success is the retained revenue after deducting obligations and costs over several months, rather than at a single point on a chart.

Who gets the fees from the successful chain?

Sorter revenues do not necessarily belong solely to the brands on the blockchain websites. Robinhood Chain uses Arbitrum technology, and reports on its revenue agreements by crypto.news mention that in certain Orbit deployments, a portion of the net protocol revenue flows into the Arbitrum ecosystem. This definition is based on net protocol revenue, not the total gas paid by users. Ethereum receives data publishing and settlement fees, chain operators retain their contracted portion, and applications can also earn their own fees. Each of these represents a different type of cash flow.

Therefore, the Ethereum base layer itself also faces the issue of value capture. Cheaper blobs and competition will reduce the fees that rollup pay to Ethereum, even though transactions still flow within its secure ecosystem. This is a positive for affordable scalability, but it constitutes a constraint on the direct destruction of fees. The analysis of Ethereum fee destruction by crypto.news explores this tension. However, the economic fate of ETH cannot be judged solely by the on-chain cost of a certain Layer; ETH may be used as gas, collateral, or reserves, and settlement demands will also change with capacity variations.

For operators, the number of transactions itself can be misleading before revenue sharing is considered. A game may generate a large number of low-cost operations but lack the corresponding ability to charge users; subsidized activities can be very sensitive to increases in fees. The statistics on active addresses count the number of wallets, not the number of unique customers. The total locked value includes price changes and large passive deposits. Transaction volume may simply represent a rapid turnover of the same pool of liquidity. A more reliable business metric is: how many paying users remain after promotional rewards end, and how much value of that is actually retained by the network.

What does it mean to close for users?

Closing a bridge is not as simple as removing a list from a website. Users may hold tokens stored in the bridge contract, balances in the application, positions, pending withdrawals, and assets issued only on the closed chain. Traditional bridge exits may require waiting and Ethereum; application positions may also need to be liquidated first. The promise that assets can still be withdrawn through contracts even after the front-end disappears assumes that users can correctly find and use these contracts. Risks and exit mechanisms will vary depending on the chain architecture.

The deadline of October 26th announced by Blast makes this distinction immediately apparent. The date of December 15th set by Abstract provides a longer migration period according to the announcements from the operators mentioned in the reports, but users should follow the instructions published on the blockchain and verify whether there are recognized bridging or redemption pathways for a particular token. Neither the transaction history nor the brand's past financings can guarantee that the sorter will operate indefinitely. The access provided by RPC will not always be available, nor will customer service staff be online at all times. The individual project pages of L2BEAT disclose risks related to operation and upgrades, which are just as important as the fees mentioned in the promotions.

One possible response is integration: applications migrate to larger chains, with specialized operators sharing infrastructure, resulting in fewer enterprises maintaining their own complete and independent technology stacks. Another approach is differentiation: a certain chain has attractive enough applications or distribution channels to fund its own operations. These are all business possibilities, not predictions that every smaller chain will be shut down. The shutdown events highlight the issue of break-even; the surviving models must prove how they will overcome this challenge.

Subsidies seem like a necessity until they end.

Many chains offer subsidies, points, fee rebates, or token rewards when they launch. These incentives can attract developers and users before a natural market has formed within the network. On the dashboard, subsidized transactions are still counted as such, and temporarily bridged assets are still included in the guaranteed value. The real financial question is: how many users will remain once the rewards stop, and whether the fees they pay will be sufficient to cover the costs of the chain. If a project's activity results in higher cash costs than the fees it collects, that merely indicates customer expenditure, not proof of profit for the chain.

When tokens are used to pay for incentives, accounting becomes particularly difficult. Teams may describe rewards in terms of token units, yet the infrastructure bills are denominated in US dollars. A decline in token prices can weaken the expenditure capacity of the treasury, even if the volume of transactions remains stable. Rising prices can support expenditures for a period of time, but they do not generate sustainable operating income. Investors may value tokens based on governance rights or expected activities, but their market value is neither the bank balance of the operators nor a guaranteed source of maintenance funds.

Turning it off will also result in costs that are not visible on the gas chart. Developers must migrate contracts, users must liquidate their positions, exchanges must adjust deposit pathways, and support teams need to help retrieve stranded assets. If a chain claims to use Ethereum for settlement, then the precise ability to exit still depends on the proof-of-work system, data availability, bridge design, and administrator permissions. While recovering assets through contracts is better than having no pathway at all, it can be much more difficult for ordinary users. Therefore, financial sustainability and a credible exit strategy should be part of the same set of evaluations for a chain.

rollup Operator's Balance Sheet

The cash inflow for operators starts with transaction fees, plus any payments for infrastructure, sorting rights, or corporate services. The direct outflows on the chain include fees for Ethereum data and proof of work publication. This difference can usually be estimated from public transactions using dashboards. Other expenses are less noticeable: servers, monitoring, auditing, client software, bridge maintenance, incident response, business expansion, legal work, subsidies, and token incentives. Even if there is a positive difference after deducting the costs associated with putting things onto the blockchain, it may still correspond to a negative operating profit margin.

This point is precisely the core of what Blast states. The project page for L2BEAT tracks its transactions and the costs of sending them to Ethereum, but these network fees are just a part of what is required to maintain the availability of Blast. The operators claim that the total ongoing costs exceed the revenue from Layer by 2 times. Public dashboards do not provide information regarding their specific salaries, infrastructure contracts, or support bills. Therefore, the lower blockchain transaction costs of L1 cannot override the business explanation given by the team. Similarly, the team's explanation should not be regarded as audited financial statements, unless they disclose precise figures for their losses.

The brand applications of Abstract form another type of accounting boundary. The sales of these applications, as well as fees from games or exchanges, may belong to the applications themselves, even if the transactions occur on Abstract. The blockchain may indirectly benefit, as application users pay gas, but the very low gas means that the blockchain receives a small amount of money from each transaction. Operators may own part of the applications, or there may be commercial agreements in place, but public income statements for the applications do not disclose the complete ownership and transfer arrangements. The total monthly income of all applications on the blockchain, which amounts to 1 million US dollars, does not equate to the monthly income of the company that operates their sorters, which is also 1 million US dollars.

Costs can be incurred in a dispersed manner. Security audits, upgrades, or bridging incidents may require significant expenditures at certain times. A busy trading day might bring in abnormally high gas income, but once the event is over, that income disappears. Annualizing the best day's performance and comparing it to the average on-chain costs will exaggerate the apparent profitability. A credible break-even analysis should use data from several consecutive months and clearly account for incentives and fixed expenses. It also needs to take into account that if the blockchain attempts to cover more costs, user fee policies may change accordingly.

Who bears the cost of low-fee transactions?

Low fees are beneficial for users, but operators can achieve this in various ways. Efficient compression and inexpensive blob capacity reduce the actual resource costs. Subsidies transfer part of these costs to the treasury, investors, or partners. If low data fees can be passed on to users while retaining the profits of the sorter, this model can sustain the business as long as there is sufficient transaction volume. However, the sustainability of these approaches varies. The prices that users see on the wallet interface may seem similar, but they are not aware of which entity is covering the difference in costs.

The same issues apply to developer incentives as well. Subsidies can encourage teams to deploy and build liquidity before the network has acquired natural users. If an application relies on the continuous distribution of tokens, its transactions and deposits may decline when rewards decrease. If users stay because the application offers something that they cannot find elsewhere, then operators may continue to maintain fee-based activities even after the incentive program ends. This is why the retention of fees after reuse and the end of incentives is more important than a surge in the number of addresses in the month of launch.

Larger chains can spread fixed costs over more transactions, although they may also need to spend more on engineering and security. Exchanges with millions of customers can distribute access rights to their own chains. A brand that focuses on consumer products can attract attention, but may find that this attention does not translate into enough transactions where customers are willing to pay. General-purpose chains without unique distribution channels may need to invest more than their competitors in order to attract the same number of applications. What determines whether the profit margin can support an organization is not just the low L1 costs of going online, but also scale.

Technical choices also affect costs and risks. Chains that release less data to Ethereum can reduce costs, but at the same time, they change the assumptions on which users rely when rebuilding their states and exiting the system. Operators of centralized sorting systems may offer simpler services, but they become single points of failure until decentralized operations are fully established. Chains that provide complex proof-of-work systems incur development and verification costs. If these designs are compared in terms of gas profit margins without considering the security services provided, the cheapest option may seem most attractive on paper, yet it is also the weakest.

The closure event highlights the value of exit paths

Users holding ETH which is bridged in through rollup may be able to exit via the official bridge of that chain, but this will be subject to delays and system security constraints. Other tokens may rely on external bridges or the redemption commitments of their issuers. Typically, LP positions must be closed first before assets can be bridged again. The native assets of the chain may not have corresponding value on the Ethereum mainnet. Therefore, a network shutdown would result in each balance requiring a different process for transfer, rather than there being a single, universal transfer option.

Blast indicates that after a temporary suspension related to its Lido asset, the withdrawal delay will be reduced to 24 hours. It sets October 26th as the deadline for the regular interface, while also stating that the contract can still be used thereafter. As the process progresses, users need to verify the schedule and the official procedures. While it is technically possible to exit the smart contract, it remains difficult for those who have never interacted directly with Ethereum contracts. Tools, documentation, and customer support will all affect whether the theoretical rights can be realized in practice.

It is reported that on December 15th, the deadline for Abstract, a similar challenge was posed to the application and its users. While contracts could be migrated, balances and positions were not automatically transferred accordingly. Liquidity had to be moved over, and token issuers might need to recognize assets on another chain. Exchanges also had to update their supported deposits. Advance notification by the operators could reduce unexpected issues, but the architecture of the chain determined whether users would be able to retrieve their funds independently in the event of a disruption in normal services.

For developers deciding on the next deployment location, the financing and exit arrangements of the operators themselves constitute a product feature. A chain with low fees but a lack of sustained funding may lead to migration costs in the future. On the other hand, a chain with sufficient funds but poor bridging protection will expose users to risks in another way. Risk assessments and project documentation for L2BEAT can assist in this decision-making process, but they cannot replace the need to read the specific contracts and monitor governance changes. Two recent closures have turned these assumptions into current operational issues.

What is worth paying attention to?

Pay attention to whether Blast has completed the temporary liquidation of Lido assets, restored withdrawals, and released the contract details it promised by October 26th. Also, pay attention to Abstract's migration guidelines before December 15th, as well as the value that is still locked on the chain. For a broader market, compare the ongoing on-chain fee income with the costs of launching projects on Ethereum, and then look for disclosures regarding operating expenses, subsidies, technology stack costs, and application revenue sharing. Only the number of transactions is reported; their profit margins are not disclosed.

The blob fee market of Ethereum, the L2BEAT value and risk indicators, as well as the rows for chain revenue and application revenue defined by DefiLlama, can all reveal part of the answer, but they cannot replace the complete accounts of the operators. A more likely demarcation line is not the cost of a single rollup transaction, but rather whether useful activities can be transformed into sustained revenue while providing users with a reliable exit path.

Frequently Asked Questions

Why do some Ethereum Layer 2s get shut down?

Blast clearly indicates that the ongoing operating costs have exceeded its Layer revenue. The operators of Abstract have also reported losses when financing for that chain. The cost and revenue structures of each project are different.

Did the cheap blob space lead to the closure?

It has reduced the cost of data on-chain and user fees for rollup, but the operators still have to bear the expenses for infrastructure, security, and business operations. The closure cannot be attributed solely to the pricing of blob.

gas Is income equal to net profit?

Does not equal. Ethereum settlement, infrastructure, employees, auditing, incentives, support, and contract sharing may all require payment from the total fees.

Can a popular app revive a non-profitable blockchain?

It is only feasible when the operator can obtain sufficient revenue or strategic value from it. Application revenue usually belongs to the application, unless the protocol stipulates that a portion of it should be transferred to the blockchain.

Can the total locked-up value reflect profitability?

No. It tracks the value of assets held by the system, which fluctuates with prices and deposits, and does not include any retention fees or operating costs.

What is the regular withdrawal deadline for Blast?

The team has indicated that the date is October 26, 2026, and the regular interface will be available until that day; it means that withdrawals can still be made through contracts on Ethereum after that time, and specific operations need to follow the instructions provided.

Abstract When is the plan to stop?

It is reported that the planned closure date by the operator is December 15, 2026. Users need to check their own migration instructions for specific assets and applications.

Are the financial conditions of all Ethereum Layer 2 versions the same?

They are different. The distribution channels, the volume of activities, the cost policies, the contracts, and the costs are all distinct. The closure of one blockchain only reflects its own economic situation, not the consolidated income statement of the entire industry.
