1. Arbitrum (ARB) – “The current leader of Layer 2”

Arbitrum uses Optimistic Rollup, notable for its high stability, low fees, fast speed, and an extremely rich DeFi ecosystem. With over 600 dApps and a TVL exceeding 5 billion USD, Arbitrum has asserted its position as number one in the Layer 2 race. Notably, ARB has a clear DAO mechanism, a solid community, making it the top choice if you want to approach Layer 2 from a “long-term value” perspective.

2. Optimism (OP) – “Open architecture – long-term strategy”

Optimism also relies on Optimistic Rollup technology, but its strength lies not only in technology but in strategy: building a Superchain – a network of multiple Layer 2s compatible with the OP Stack. This is the ideal choice for builders. However, the ecosystem depends quite a bit on funding from the Optimism Collective, and decentralization is not really high. The $OP token has been listed but is still under vesting pressure.

3. zkSync Era – “The technology pioneer – but not fully matured yet”

zkSync Era implements zk-Rollup – the most advanced technology currently with the ability to process transactions extremely quickly and superior security. However, the ecosystem is still young, and there is no official token (although an airdrop is anticipated). This is a “potential mystery” in the long term, suitable for those who prefer to venture into core technology investments (infrastructure play).

4. Base (Coinbase) – “A fresh breeze from Web2 to Web3”

Base, developed by Coinbase, is tightly integrated with the largest CEX in the U.S. Although it uses Optimistic Rollup, its strength lies in its ability to reach mainstream users and commercialize Web3. Base currently does not have its own token, but the ecosystem is growing rapidly thanks to brand power. However, it is still quite a centralized network, suitable for those who believe in the role of “Web2 giants” in the future of blockchain.
