The Pectra upgrade introduces expanded blob space, smart accounts, and validator improvements

The Pectra upgrade introduces expanded blob space, smart accounts, and validator improvements that could significantly impact Ethereum Layer-2 ecosystems. Arbitrum (ARB), StarkNet (STRK), Mantle (MNT), Aevo (AEVO), and Fuel (FUEL) are five key tokens to watch as they stand to benefit from lower data costs, increased scalability, and enhanced functionality.

While all five tokens have recently faced price corrections, on-chain upgrades could act as a tailwind in the coming weeks. Each of these Layer-2s is positioned to gain from Ethereum’s evolving infrastructure—if momentum returns, upside potential is on the table.

Arbitrum (ARB)

With expanded blob space and more efficient data availability coming from the Ethereum Pectra upgrade, Arbitrum can reduce its L1 settlement fees and scale more efficiently.

At the same time, EIP-7702 introduces smart account functionality that enables gasless transactions, batching, and simplified onboarding, all of which enhance the experience for developers and end users building on Arbitrum.

Despite these long-term tailwinds, ARB is down over 6% in the past seven days. If the correction continues, price may fall to $0.292 — a key support level — and potentially dip further to $0.27.

However, if ARB regains momentum, the first resistance to watch is $0.315.

A break above that level could open the door for further upside toward $0.345 and, in a stronger bullish scenario, $0.363.

StarkNet (STRK)

The Pectra upgrade introduces improvements in data availability and validator operations, which will benefit StarkNet in multiple ways.

Enhanced blob space directly supports cheaper and more scalable calldata posting — a major win for zk-rollups like StarkNet that rely heavily on L1 for data availability.

Additionally, EIP-7002 allows more flexible validator withdrawals, which supports future integrations of re-staking protocols and simplifies cross-chain liquidity movements.

STRK has fallen more than 13.5% in the past seven days, and its EMA lines indicate a downtrend. If this trend continues, the next key support level is around $0.116.

However, if STRK manages to reverse momentum, the first resistance to watch is $0.136. A break above that level could lead to further upside, with STRK potentially testing $0.15 and even $0.161 in a stronger bullish scenario.

Mantle (MNT)

The Pectra upgrade brings improvements that could indirectly support Mantle’s modular architecture and staking design. With EIP-7251 raising the validator staking limit, large-scale staking operations become more efficient — a potential benefit for Mantle, which integrates restaked ETH into its ecosystem.

This change simplifies validator management and enhances the economic security of protocols that rely on Ethereum as a base layer.

Additionally, the expansion of blob space contributes to lower L1 data costs, supporting cheaper and more scalable interactions for Mantle’s modular rollups and Layer 2 applications.

MNT formed a death cross a few days ago and is currently down 2.6% over the past seven days, signaling ongoing bearish pressure. Its next key support sits at $0.68, and if that level fails to hold, price could decline further toward $0.652.

On the upside, if MNT reverses course, the first resistance to watch is $0.72.

A successful break above that could trigger a rally toward $0.759, and in a more extended bullish move, MNT may test $0.809.

Aevo (AEVO)

Aevo, a high-performance derivatives platform built on Layer 2 infrastructure, stands to benefit from the Pectra upgrade through lower data availability costs and improved scalability.

The expansion of blob space introduced by Pectra reduces calldata fees for L2s, which is crucial for platforms like Aevo that rely on frequent state updates and high transaction throughput. This directly translates to cheaper and faster settlement for perpetuals and options.

Additionally, smart account functionality from EIP-7702 could enable features like gasless trading or streamlined account recovery, enhancing the trading experience and reducing friction for users interacting with Aevo’s contracts.

AEVO is down nearly 12% over the last seven days, with its price struggling to stay above the $0.10 mark.

If this downtrend continues, the next support is at $0.096 — and a break below that could open the door to deeper declines toward $0.082 and even $0.0756.

On the flip side, if AEVO regains momentum and
