Ethereum’s congestion has fueled a Layer-2 boom. Optimism and Arbitrum lead the pack, both offering rollup solutions that batch transactions off-chain. Optimism boasts strong developer grants and EVM equivalence, while Arbitrum’s Nitro upgrade slashes gas costs further.

Users should balance network fees, withdrawal timeframes (7 days vs. instant bridges), and ecosystem dApps. As TVL grows on both, bridging infrastructure and cross-rollup composability will be the next frontier.
