Introduction: The Importance of Rollups in Ethereum Scalability and Other Chains

Ethereum’s roadmap, which centers on rollups, has reached full maturity in 2026. The rollup ecosystem started as an experimental L2 (Layer 2) scaling solution around the beginning of 2020.

Today, this ecosystem has become a primary place where developers and organizations execute DeFi (Decentralized Finance), on-chain AI (Artificial Intelligence) agents, gaming, and RWA (Real World Asset) protocols.

The blob transaction optimizations and data availability upgrades of the Ethereum network in 2025 led to a dramatic fee reduction and an increase in throughput among rollup protocols.

The result is that over 50% of user activity on Ethereum today settles on L2 blockchain networks. 

Furthermore, DeFi liquidity is fragmented across different rollup protocols, and many institutional investors interested in capital efficiency prefer Layer 2s.

This CoinEx article explores the top 5 rollup coins in February 2026, shaping the current crypto cycle. 

The Rollup Sector Between 2025 and Early 2026

Ethereum network scalability underwent significant structural shifts in 2025.

• RWA tokenization, credit markets on the blockchain, and stablecoin growth were deployed more on Layer 2 infrastructure.

• Modular rollup stacks enabled fast, custom chain deployment

• Zk rollup ecosystems became production-ready. 

• Liquidity routing improved through cross-rollup messaging. 

In 2026, the rollup ecosystem has become a strong-performing segment of the crypto infrastructure landscape. The ecosystem currently has sustained developer activity, and more institutions are experimenting with it.
