The Ethereum blockchain is approaching a significant milestone as its total supply nears the levels seen before the Merge event in September 2022. This development comes despite increased network activity driven by Layer-2 scaling solutions and the introduction of blobs through the Dencun upgrade.
Understanding Ethereum's Supply Dynamics
Ethereum's transition to Proof-of-Stake through the Merge was designed to reduce the network's energy consumption and alter its issuance model. Initially successful in making the supply deflationary, the trend reversed following the Dencun upgrade in March 2023.
The ETH supply had decreased by approximately 460,000 tokens since the Merge but has since become inflationary. Current data indicates the supply will likely surpass pre-Merge levels within the next two weeks if current trends continue.
Layer-2 Ecosystem Expansion
The Dencun upgrade significantly reduced transaction fees across Ethereum's Layer-2 solutions, leading to a substantial migration of activity from the main chain. Prior to the upgrade, Ethereum handled 31% of transactions while Layer-2s processed 69%. Today, only 10% of transactions occur on the main chain, with Layer-2s processing the remaining 90%.
Base has emerged as the dominant Layer-2 solution, accounting for over 60% of all Layer-2 transactions. The platform achieved a remarkable 290 million transactions in December 2024 alone, setting a new all-time high for network activity.
Despite this transaction volume disparity, Ethereum mainnet transactions still contribute approximately 80% of total transaction fees. Among Layer-2 solutions, Base leads by contributing about 10% of total fees, while other Layer-2 networks contribute minimal amounts.

The Role of Blobs in Ethereum's Economics
Blobs represent a crucial innovation introduced during the Dencun upgrade. These large data packets, each capable of holding 128kb of information, are included in Ethereum blocks but only stored for 18 days, reducing permanent blockchain storage requirements.
Since October, blobs have consistently operated at the target rate of three per block, with the current limit set at six per block. Transaction fees typically increase when blob usage exceeds the target threshold, creating economic incentives for network participants.
In the past 30 days, blob fees have burned approximately 1,200 ETH, placing them as the fourth-largest burning mechanism behind Uniswap, ETH transfers, and Tether transactions. Notably, Uniswap alone burns more ETH than all Layer-2 solutions combined.
Current Burn Mechanisms and Their Impact
The Ethereum burn mechanism continues to function through various network activities, though at reduced efficiency compared to pre-Dencun levels. The distribution of burn contributions shows:
- Uniswap leading as the largest ETH burner
- Standard ETH transfers ranking second
- Tether transactions following closely
- Blob fees contributing significantly but ranking fourth
The total transaction count across all Layer-2 solutions has remained relatively stable at around 19 million since August. This consistency suggests that a substantial increase in transaction volume would be necessary to push blob usage beyond the current target threshold.
Future Outlook for Ethereum's Supply
The Ethereum supply will likely remain inflationary unless Layer-2 transaction volume increases significantly. For the supply to become deflationary again, blob usage would need to consistently exceed the target threshold of three per block, driving up transaction fees and increasing the amount of ETH burned.
Network upgrades and adoption patterns will continue to influence Ethereum's economic model. The potential migration of major protocols like Uniswap to dedicated chains could further impact the burn rate and overall supply dynamics.

Frequently Asked Questions
What caused Ethereum's supply to become inflationary?
The Dencun upgrade dramatically reduced transaction fees on Layer-2 solutions, which consequently decreased the amount of ETH burned during transactions. This reduction in burn rate, combined with continued ETH issuance, shifted the supply from deflationary to inflationary.
How do blobs affect Ethereum's economics?
Blobs are data packets that help reduce permanent storage requirements on the blockchain. Their usage generates fees that contribute to ETH burning, but current usage levels haven't been sufficient to offset the reduced fees from Layer-2 transactions since the Dencun upgrade.
Can Ethereum's supply become deflationary again?
Yes, if Layer-2 transaction volume increases significantly enough to push blob usage consistently above the target threshold, resulting in higher transaction fees and increased ETH burning. This would require substantial growth in network activity beyond current levels.
What is the significance of Layer-2 solutions for Ethereum?
Layer-2 solutions help scale Ethereum by processing transactions off the main chain while maintaining security guarantees. They reduce congestion and fees on the main network but also affect the economic model by changing fee structures and burn mechanisms.
How does Base compare to other Layer-2 solutions?
Base has emerged as the dominant Layer-2 solution, handling over 60% of all Layer-2 transactions while contributing approximately 10% of total transaction fees. Its growth has significantly impacted Ethereum's overall transaction distribution and economic model.
What happens if Uniswap moves to its own chain?
If Uniswap completes its migration to Unichain, Ethereum would lose its largest source of ETH burning. This could further exacerbate the inflationary supply trend unless other applications or mechanisms compensate for the reduced burn rate.
