This Skill helps teams and developers cut through marketing and outdated assumptions to pick the correct Ethereum Layer 2, understand per-chain tradeoffs, and deploy or bridge safely and cost-effectively.
Compare Arbitrum, Base, and zkSync for a consumer payments app focusing on gas cost, finality/withdrawal time, RPC and bridge security, and dominant DEX liquidity.

Comparing Ethereum Layer 2 networks involves evaluating gas costs, block times, finality, and withdrawal times across Arbitrum, Base, Optimism, and zkSync. You must also assess per-chain DeFi liquidity, bridge security, and deployment compatibility to find the optimal fit.
Launching on Base offers low fees and Coinbase on-ramps for consumer apps, while Arbitrum provides deeper liquidity and composability for DeFi protocols. Choosing between them depends on whether your priority is user onboarding cost or complex financial ecosystem integration.
Bridging assets to zkSync or Scroll requires using verified bridge URLs and specific RPC endpoints provided by the network. You must also account for withdrawal times and distinct deployment gotchas associated with zero-knowledge rollups versus optimistic rollups.
Deployment gotchas for optimistic versus zk rollups involve distinct finality windows, withdrawal delay mechanisms, and CREATE2 address calculation differences. Migration warnings highlight smart contract compatibility issues and varying security assumptions when moving between Layer 2 networks.
Using CREATE2 across Layer 2 networks like Optimism and Celo requires chain-specific guidance to ensure address consistency. You must verify RPC endpoints and account for unique migration warnings and compatibility constraints inherent to each rollup architecture.
