Cronos zkEVM

This is a Gnosis Safe with 4 / 7 threshold. This MultiSig is the current central Governor for upgradeability and configuration of all shared ZK stack contracts and each Hyperchain under it and can potentially steal all funds.

Those are the participants of the Matter Labs Multisig.

Can manage fees, apply predefined upgrades, censor bridge transactions and revert batches (Admin role in the CronosZkEvm contract).

This is a Gnosis Safe with 2 / 3 threshold. Inherits all permissions of the CronosZkEVMAdmin contract.

Those are the participants of the AdminMultisig.

Inherits all permissions of the CronosZkEVMAdmin contract.

Actors that are allowed to propose, execute and revert L2 batches on L1 through the ValidatorTimelock.

The main Rollup contract. The operator commits blocks and provides a ZK proof which is validated by the Verifier contract then processes transactions. During batch execution it processes L1 --> L2 and L2 --> L1 transactions.

Intermediary governance contract that has the Admin (not upgradeability admin) role for the Cronos zkEVM diamond contract.

Intermediary contract between the Validators and CronosZkEvm that delays block execution (ie. withdrawals and other L2 --> L1 messages).

Implements ZK proof verification logic.

This bridge contract escrows all assets that are deposited to Cronos zkEVM and other chains in the Hyperchain Ecosystem.

Sits between the single shared bridge and the StateTransitionManager(s) and relays L1 <-> L2 messages from the shared bridge or other ZK stack chains to their respective destinations.

Defines shared L2 diamond contract creation and upgrade implementations and the verifier for the Hyperchain contracts connected to it.
