Viewed through the lens of developer ecosystems, Optimism differentiates itself by emphasizing open-source modularity and shared sequencer revenue via the Superchain vision. This encourages multiple chains to build on the OP Stack, potentially creating network effects across Layer 2s. Arbitrum, by contrast, has cultivated a dense and active developer base around a single dominant rollup, benefiting from strong tooling, backward compatibility, and lower friction for teams migrating from Ethereum mainnet.
