Optimism, a prominent altcoin project, has announced a significant breakthrough by introducing support for Layer 3 networks. This integration enables Layer 3 networks to be built on the OP Stack and join the Superchain, fostering a collaborative ecosystem. By sharing sequencer revenue with the Optimism Collective, Layer 3 founders gain access to a comprehensive suite of benefits, including retrospective funding, airdrops, growth campaigns, and a vast developer network .

To facilitate seamless integration, Optimism has introduced two innovative features to the OP Stack. Custom gas tokens empower networks to design their transaction fees, while Plasma Mode allows networks to choose their preferred data availability (DA) layers. This flexibility enables Layer 3 networks within the Superchain to deviate from standard OP Stack configurations, unlocking interoperability features .

Infrastructure teams such as Syndicate, Caldera, Gelato Network, Chaindrop, Zeeve, and Conduit will provide support to projects developing Layer 3 networks within the Superchain. Notably, Layer 3 networks are designed for specific applications, offering high customizability and the capacity to handle significantly larger transaction volumes compared to Layer 1 and Layer 2 networks .

Optimism is not the only project pioneering the development of Layer 3 network ecosystems. Offchain Labs, the team behind Arbitrum, introduced "Orbit" development tools in April 2023 to facilitate Layer 3 network development. Similarly, zkSync offers Layer 3 features through "Hyperchains," underscoring the Growing interest in Layer 3 networks .
