In 2025, Ethereum’s Layer 2 ecosystem is a compelling investment due to robust developer and community engagement. Arbitrum’s 24.95 million monthly transactions and 405 active protocols dwarf Optimism’s 13.95 million and 164, signaling stronger developer adoption. Its Arbitrum DAO and ARB token governance empower community-driven upgrades, while partnerships like LayerZero enhance interoperability. Optimism’s OP Stack, adopted by Coinbase’s Base, simplifies custom chain creation, attracting developers. Its Optimism Collective, with Token House and Citizens’ House, funds public goods, fostering loyalty and innovation. Optimism’s smaller ecosystem lags in scale but excels in community alignment.
