Included contracts

The supersim chain environment includes contracts already deployed to help replicate the Superchain environment. See OP Chain A for contract address examples for a L2 system.

OP Stack system contracts (L1)

These are the L1 contracts that are required for a rollup as part of the OP Stack protocol. Examples are the OptimismPortal (opens in a new tab), L1StandardBridge (opens in a new tab), and L1CrossDomainMessenger (opens in a new tab).

For more details, see example contracts or the source code (opens in a new tab).

OP Stack L2 contracts (L2)

The OP Stack system contracts on the L2 are included at the standard addresses by default.

• Standard OP Stack predeploys (L2) (opens in a new tab)
• Interoperability predeploys (experimental) (L2) (opens in a new tab)
• OP Stack preinstalls (L2) (opens in a new tab)

Periphery contracts (L2)

L2 chains running on supersim also includes some useful contracts for testing purposes that are not part of the OP Stack by default.

L2NativeSuperchainERC20

A simple ERC20 that adheres to the SuperchainERC20 standard. It includes permissionless minting for easy testing.
