In 2025, Ethereum’s Layer 2 ecosystem is a compelling investment due to its role in enabling interoperable Web3 applications. Arbitrum’s competitive edge lies in its partnerships with cross-chain protocols like LayerZero and Chainlink CCIP, facilitating seamless asset transfers across blockchains. Its Arbitrum Orbit allows bespoke Layer 3 chains, enhancing interoperability for enterprise use cases. Optimism’s OP Stack, adopted by projects like Base and Worldcoin, creates a modular “Superchain” ecosystem, unifying multiple L2s under shared governance. Its EVM equivalence simplifies cross-chain dApp deployment. While Arbitrum excels in cross-chain infrastructure, Optimism’s Superchain vision offers a scalable framework for future interoperability.
