Will L2 Sequencer Revenue Continue to Decline?
Most likely, yes. The virtuous cycle of sequencer revenue—users pay, L2s settle cheaply, pocketing fat margins—is being squeezed simultaneously by three structural forces: fee wars among L2s, cost collapse from tech upgrades, and the trend toward decentralization siphoning off profits.

Two sources of sequencer revenue are being eroded one by one
Sequencers make money mainly from two things: the spread between transaction fees paid by users minus the cost of posting to the Ethereum mainnet; and the capture of MEV (Maximal Extractable Value).
First, the spread. After the Dencun upgrade (EIP-4844) introduced blob space, the cost for L2s to post data to the mainnet plunged over 90%. As costs fell, competition among L2s immediately passed all the savings on to users—any chain that didn't would lose users. The result: before the upgrade, top L2s earned a profit of $0.06 to $0.60 per transaction; six months after the upgrade, that dropped to $0.01 to $0.04, shrinking by more than 90%.
With per-transaction profit down 90%, transaction volume would need to grow 10x just to maintain total revenue. But current data shows L2 transactions rose from a pre-Dencun average of 4.7 million per day to 15.2 million—an increase of about 3.2x—nowhere near enough to fill the profit hole. As a result, total revenue for Ethereum L2s dropped 53% in 2025 to $129 million, based on analysis of publicly available search results.
Now, MEV. Sequencers capture MEV by adjusting transaction ordering, and theoretically this revenue remains unaffected. But the problem is that the trend toward sequencer decentralization is taking MEV away from centralized sequencers—schemes like multi-node shared sequencing and encrypted mempools all dilute a single sequencer's ability to capture MEV.
The bigger problem: sequencer revenue isn't coming back
If you think "fees will bounce back when the network gets congested and sequencer revenue will naturally recover," you need to re-understand the logic of L2 operators.
An L2 operator is a business; it will proactively avoid creating a high-fee environment for itself. Blob space has an automatic pricing mechanism—if there are more than 4 blobs in the current block (the target is 3), the base blob fee for the next block will rise by about 12%. When blob fees start climbing, what do L2s do? Delay posting, reduce posting frequency, or even switch back to cheaper submission methods.
A real-world case: in June 2024, the LayerZero airdrop caused a spike in transactions on Arbitrum, sending blob fees soaring. Scroll completely stopped publishing blobs, and Taiko slowed its batch transactions by 30-50%.
L2s are actively smoothing their own cost curves, meaning sequencer fees will never rise significantly—at least not to the point where sequencer operators return to the days of fat margins.
As a user or token holder, how to gauge the trend
Step 1: Check the revenue structure of the L2 you're tracking.
Open Token Terminal or Dune and look at three metrics for your L2 over the past 90 days: Total Revenue (Protocol Revenue), costs paid to L1, and transaction volume growth rate.
Scenario A: Revenue keeps falling, cost ratio is very low, volume growth is slowing.
The probability of sequencer revenue continuing to decline is high. In Q4 2025, Base earned $19 million in sequencer revenue while paying just $360,000 in L1 fees—an extremely high margin but the absolute revenue scale has shrunk dramatically compared to the Ethereum L1 peak.
Scenario B: Revenue is steady, MEV capture share is high, decentralization progress is slow.
These L2s may hold revenue levels in the short term, but face long-term pressure from profit diversion as decentralization advances.
Completion criteria: You've identified which state your L2 is currently in.
Step 2: Pay attention to the Pectra upgrade timeline.
The Pectra upgrade is expected to expand blob capacity by 2-3x, further lowering L2 submission costs. The lower the cost, the fiercer the competition, the lower the user fees, and the lower the sequencer revenue.
Completion criteria: You know the rough timing window of the Pectra upgrade and its directional impact on fees.
Risk warning
Risk of holding L2 native tokens (ARB, OP, etc.): Sequencer revenue rarely flows back to token holders. Arbitrum processes about 1.9 million transactions per day with over $1.2 billion in TVL, yet sequencer daily revenue is only around $14,300. ARB is currently a pure governance token—holders receive no network revenue share, no staking yield, no token burn mechanism.
Risk for ETH holders: Falling L2 fees lead to reduced ETH burn, shifting ETH's narrative from "ultrasound money" to "scalable computing network." If L2 revenue continues to trend lower, ETH's deflationary narrative will face persistent challenges.

How to confirm this is happening
If you hold an L2 token, open its Token Terminal page and check the trend of the "Revenue" and "Costs" metrics over the past year. If both are trending down, the decline in sequencer revenue is already underway. If you're just an L2 user, check whether your recent transaction gas fees are indeed lower than they were six months ago—if yes, at least a portion of the sequencer's shrinking profit has ended up in your pocket.
Next step: If you hold L2 tokens, research whether the project has a "revenue conversion mechanism"—such as using sequencer revenue to buy back tokens or distribute fees. If not, the economic rationale for holding that token may need to be reassessed. Also, keep an eye on the progress of the Pectra upgrade; every major change in L2 cost structure will further compress sequencer profit margins.
