Get an overview of the capabilities associated with an OP Stack chain. While the OP Stack allows for full customization, chains in the Superchain adhere to a standard set of technical and governance parameters, facilitating Superchain interoperability, network security, and ease of upgrading your chain.

1Data for Superchain from Base. Data for OP Stack from opBNB. 2The standard blockspace charter has a max gas limit of 200m. Both gas limit and gas target can be configured through the system config. 3While protocol blocktimes can be lowered to 1 second, subsecond blocktimes can be achieved using Rollup Boost and Flashblocks. 4Although ETH is the gas token, chain operators can achieve the same UX of a custom gas token by using an ERC-20 paymaster.
