OP Mainnet

Central actor allowed to submit transaction batches to L1.

Admin of OptimismPortal, L1StandardBridge, L1ERC721Bridge, OptimismMintableERC20Factory, SuperchainConfig, DelayedWETH, DisputeGameFactory, AnchorStateRegistry and SystemConfig contracts.

This is a Gnosis Safe with 2 / 2 threshold. Owner of the SuperchainProxyAdmin. It can upgrade the bridge implementation potentially gaining access to all funds, and change any system component. It also controls the L2ProxyAdmin, meaning it can upgrade L2 system components.

Those are the participants of the SuperchainProxyAdminOwner.

This is a Gnosis Safe with 1 / 1 threshold. It uses the following modules: DeputyGuardianModule (allows the FoundationMultisig_2, called the deputy guardian, to act on behalf of the Gnosis Safe). Address allowed to pause withdrawals or blacklist dispute games in case of an emergency. It is controlled by the Security Council multisig, but a module allows the Foundation to act through it. The Security Council can disable the module if the Foundation acts maliciously.

Those are the participants of the GuardianMultisig.

This is a Gnosis Safe with 5 / 7 threshold. Member of the SuperchainProxyAdminOwner.

Those are the participants of the FoundationMultisig_1.

This is a Gnosis Safe with 10 / 13 threshold. It uses the following modules: LivenessModule (used to remove members inactive for 8467200 while making sure that the threshold remains above 75%. If the number of members falls below 8, the FoundationMultisig_1 takes ownership of the multisig). Member of the SuperchainProxyAdminOwner. It implements a LivenessModule used to remove inactive (98d) members while making sure that the threshold remains above 75%. If the number of members falls below 8, the Foundation takes ownership of the Security Council.

Those are the participants of the SecurityCouncilMultisig.

This is a Gnosis Safe with 5 / 7 threshold. This address is the owner of the following contracts: SystemConfig.

Those are the participants of the FoundationMultisig_2.

Address collecting sequencer, base and L1 fees from L2.

The OptimismPortal contract is the main entry point to deposit funds from L1 to L2. It also allows to prove and finalize withdrawals. It specifies which game type can be used for withdrawals. The current game type is PermissionedDisputeGame. This contract stores the following tokens: ETH.

The L1CrossDomainMessenger (L1xDM) contract sends messages from L1 to L2, and relays messages from L2 onto L1. In the event that a message sent from L1 to L2 is rejected for exceeding the L2 epoch gas limit, it can be resubmitted via this contract’s replay function.

The L1StandardBridge contract is the main entry point to deposit ERC20 tokens from L1 to L2. This contract can store any token. This contract can store any token.

The L1ERC721Bridge contract is used to bridge ERC-721 tokens from L1 to L2.

It contains configuration parameters such as the Sequencer address, the L2 gas limit and the unsafe block signer address.

The dispute game factory allows the creation of dispute games, used to propose state roots and eventually challenge them.

Logic of the dispute game. When a state root is proposed, a dispute game contract is deployed. Challengers can use such contracts to challenge the proposed state root.

Same as FaultDisputeGame, but only two permissioned addresses are designated as proposer and challenger.

The MIPS contract is used to execute the final step of the dispute game which objectively determines the winner of the dispute.

Contains the latest confirmed state root that can be used as a starting point in a dispute game.

The PreimageOracle contract is used to load the required data from L1 for a dispute game.

Contract designed to hold the bonded ETH for each dispute game. It is designed as a wrapper around WETH to allow an owner to function as a backstop if a game would incorrectly distribute funds. It is owned by the SuperchainProxyAdminOwner multisig.

The SuperchainConfig contract is used to manage global configuration values for multiple OP Chains within a single Superchain network. The SuperchainConfig contract manages the PAUSED_SLOT, a boolean value indicating whether the Superchain is paused, and GUARDIAN_SLOT, the address of the guardian which can pause and unpause the system.
