Optimism’s superchain now supports layer 3 chains via the OP stack.

Optimism noted that layer 3 chains can now join the superchain by building on the OP stack and sharing sequencer revenues with its governance body, Optimism Collective.

Layer 3 builders participating in Superchain will have access to retroactive funding, airdrops, and growth campaigns along with Optimism, an extensive developer network. said.

A layer 3 chain is a network that anchors on one of Optimism’s layer 2 chains, including the OP mainnet, base, and mode.

To support the integration of Layer 3, Optimism introduces two new features to the OP stack. Custom gas tokens that allow chains to design their transaction fees, and Plasma Mode, a solution that allows chains to choose their own data availability (DA). floor.

Layer chains within a superchain deviate from the standard OP stack configuration, impacting the rollout of interoperability features. Despite these changes, Optimism is ready to integrate the L3 chain into its ecosystem.

Several infrastructure teams, including Syndicate, Caldera, Gelato Network, Chaindrop, Zeeve, and Conduit, will support projects developing layer 3 chains within Superchain.

Layer 3 chains are designed for specific applications, are highly customizable, and can handle much higher transaction volumes compared to layer 1 and layer 2 blockchains.

Optimism is not the only thing driving the ecosystem of layer 3 chains. Arbitrum’s team, Offchain Labs, introduced a development tool in April 2023 to facilitate layer 3 chain development called “Orbit”. Likewise, zkSync leverages “hyperchains” to enable layer 3 functionality.
