Layer-2 Blockchain Wars: Arbitrum vs Polygon Liquidity and User Activity Post-Ethereum Upgrade

Over the past 48 hours, Layer-2 scaling solutions have experienced significant shifts in user engagement and liquidity distribution, highlighting evolving competitive dynamics between Arbitrum, Polygon, and Base. These developments reflect ongoing fragmentation in L2 leadership amid post-upgrade network activity and liquidity realignment.

Polygon maintains dominance in daily active users, signaling stronger retail activity, while Arbitrum continues to lead in liquidity depth, underscoring its status as a DeFi liquidity hub. Additionally, Base is projected to overtake Arbitrum in daily user activity, indicating a potential shift in retail engagement patterns.

Arbitrum's liquidity depth remains higher than Polygon, despite Polygon's user engagement lead, suggesting a divergence between retail activity and DeFi liquidity pools. L2 transaction share of Ethereum’s total activity remains substantial at 58.5%, emphasizing the importance of Layer-2 solutions in network throughput post-upgrade.

In terms of total value locked, Arbitrum continues to hold the largest share at $45 billion, with liquidity rotations favoring Arbitrum’s pools amid ongoing multi-chain competition. Meanwhile, Optimism faces revenue pressure from Ethereum's BPO-1 L2 capacity expansion, risking its governance and infrastructure dominance.

Cross-L2 activity shifts show retail flows moving toward Base and Blast, while DeFi liquidity remains concentrated on Arbitrum, illustrating activity cycles that favor different chains depending on user and institutional priorities. zkSync and Scroll adoption lag behind Arbitrum and Base in liquidity and user engagement, despite potential technological advantages.

These signals collectively indicate a landscape where liquidity stability on Arbitrum coexists with retail activity growth on Polygon and Base, highlighting a fragmented yet competitive Layer-2 ecosystem with specialized roles for each platform.

These developments suggest that multi-chain liquidity and user activity are becoming more distributed across different Layer-2 solutions, influencing capital flows and infrastructure scaling strategies within the crypto ecosystem.

The dataset does not specify liquidity breakdowns beyond total TVL figures, and the projected user activity shifts are based on early analysis, which may evolve as new data emerges.
