The Ethereum Layer 2 (L2) ecosystem continues its rapid expansion, with Polygon leading in adoption among DeFi protocols. A pivotal development is OKEx's announcement to support Arbitrum network deposits/withdrawals, streamlining user access to L2 networks without costly Layer 1 (L1) interactions. This move raises questions about how exchanges like Binance and Huobi—with their own chains (BSC, HECO)—will respond, given potential asset migration back to Ethereum's more secure but cost-efficient L2 solutions.
Key L2 Network Progress (April 2024)
Optimism: Regenesis & ENS Integration
- Conducted a Regenesis to reset network state, minimizing historical data risks.
- ENS demonstrated an MVP for L2 domain resolution, enabling gas-free updates.
Arbitrum: Mainnet Launch & Exchange Support
- OKEx integration allows direct L2 transactions, bypassing L1 fees.
- Mainnet opens to developers on May 28, with a public testnet preceding.
zkSync: zkPorter & Community Debate
- Introduced zkPorter, a hybrid Rollup/Validium solution offering 100x cost reduction.
- Vitalik Buterin critiqued its security, advocating for Optimistic Rollups as interim preference.
StarkNet: Trading Milestones

- NEAR Protocol’s Aurora EVM chain went live, offering cross-chain scalability.
FAQ: Ethereum Layer 2 Solutions
Q: How do L2 solutions reduce Ethereum fees?
A: By processing transactions off-chain (e.g., Rollups) or using sidechains, minimizing L1 congestion.
Q: Will exchanges supporting L2 weaken their native chains (BSC/HECO)?
A: Potentially, but native chains retain throughput advantages for high-volume applications.
Q: When will Uniswap V3 deploy on Optimism?
A: Unconfirmed—originally slated for mid-May, but no updates post-L1 launch.
