The recent Ethereum Cancun Upgrade, particularly its core EIP-4844 implementation, marks a pivotal moment for Layer 2 scalability and cost efficiency. This upgrade promises significant gas fee reductions on major L2 networks, directly affecting user experience and potentially influencing associated token valuations.
Let's explore the real-world impact of these changes, analyze post-upgrade gas fee trends, and discuss what this means for popular L2 tokens like ARB, OP, and STRK.
Understanding the Cancun Upgrade and EIP-4844
The centerpiece of the Cancun Upgrade is Ethereum Improvement Proposal (EIP) 4844, commonly known as proto-danksharding. This innovation introduces a new transaction type called blob-carrying transactions.
Unlike the traditional calldata method—which stores transaction data on-chain in a permanent and memory-intensive way—blobs provide a much larger and significantly cheaper data storage solution. This new mechanism is specifically designed to handle the massive data output from Rollups, laying a robust foundation for future scaling efforts.
The primary goal of EIP-4844 is to drastically reduce the data storage costs for Layer 2 networks. Historically, data storage accounted for over 90% of an L2 transaction's gas fee. By optimizing this, the upgrade directly targets the most expensive component of L2 transactions, making them far more affordable for end-users.

Did Layer 2 Gas Fees Actually Become Cheaper?
The proof, as they say, is in the pudding. Following the successful activation of the Cancun Upgrade, major L2 networks began their integration processes. The rollout schedule was as follows:
- Optimism: Update completed.
- Starknet: Update completed.
- zkSync Era: Update completed.
- Arbitrum One: Updated on March 14.
- Base: Updated on March 14.
The immediate effect was a dramatic and visible reduction in transaction costs across these platforms. Comparative data from before and after the upgrade highlights this shift:
- zkSync Era: Sending ETH dropped from $0.15 to approximately $0.04.
- StarkNet: Sending ETH plummeted from $0.71 to around $0.07.
- Optimism: Sending ETH saw a massive fall from $0.36 to under $0.01.
This tangible reduction in fees makes on-chain interactions more accessible, potentially driving greater adoption and activity within L2 ecosystems.
A Note on Ethereum Mainnet Fees
It is crucial to understand that blob transactions are designed primarily to lower data costs for L2s. They do not directly target the gas fee mechanism of the Ethereum Mainnet. Consequently, while some minor indirect effects might be observed, users should not expect a significant drop in the cost of transacting directly on Ethereum Layer 1.
Market Sentiment and Token Price Considerations
The successful implementation of the Cancun Upgrade has generated substantial optimism for the future of Layer 2 networks. Lower fees enhance a network's utility and attractiveness, which can, in turn, influence the value of its native token.
- ARB (Arbitrum): As one of the largest L2s by Total Value Locked (TVL), Arbitrum stands to benefit immensely from reduced fees, potentially increasing user acquisition and retention. The health of its ecosystem is a key driver for ARB's value.
- OP (Optimism): The Optimism Collective has been a pioneer in governance and ecosystem development. A dramatic fee reduction strengthens its competitive positioning, which could positively impact investor perception of the OP token.
- STRK (Starknet): Starknet's use of zk-rollup technology is technically distinct. The upgrade's massive fee reduction for its network demonstrates improved efficiency and could attract more developers to build on its platform, potentially affecting STRK's long-term valuation.
It's important to remember that token prices are influenced by a complex mix of factors, including broader market trends, technological developments, ecosystem growth, and overall crypto market sentiment. While lower gas fees are a powerful fundamental positive, they are one of many variables in a token's price discovery process.

Frequently Asked Questions
What exactly is EIP-4844?
EIP-4844, or proto-danksharding, is an Ethereum upgrade that introduces a new data storage system using "blobs." This method is cheaper and more efficient than the previous calldata approach, specifically designed to reduce the data storage costs for Layer 2 rollups, thereby lowering transaction fees for users on those networks.
Did the Cancun Upgrade reduce fees on the Ethereum Mainnet?
No, the primary focus of EIP-4844 is to reduce costs for Layer 2 networks. While there might be some minor indirect effects on the mainnet, the upgrade was not designed to significantly lower gas fees for transactions executed directly on Ethereum Layer 1.
Which Layer 2 networks were affected by the upgrade?
All major Ethereum L2 rollups have integrated with EIP-4844, including Arbitrum, Optimism, Base, zkSync Era, and Starknet. Each has reported substantial decreases in network transaction fees following the update.
How much cheaper are L2 transactions now?
The reduction has been significant. For example, sending ETH on Optimism now costs less than $0.01, down from over $0.30. Similar drastic reductions of 50-90% were observed on other leading L2s like zkSync and Starknet.
Will lower gas fees cause L2 token prices (ARB, OP, STRK) to rise?
While lower gas fees improve a network's utility and attractiveness—a strong fundamental positive—token prices are subject to many other factors. These include overall market conditions, adoption rates, and broader macroeconomic trends. Reduced fees are bullish for ecosystem health, but do not guarantee short-term price appreciation.
What is the long-term significance of proto-danksharding?
Proto-danksharding lays the foundational infrastructure for full danksharding in the future. This paves the way for Ethereum to process over 100,000 transactions per second by further scaling data availability, cementing L2s as the primary scaling solution for the ecosystem.
