Polygon zkEVM

The main system contract defining the polygon zkEVM Layer 2 logic. Entry point for sequencing batches.

• Roles:
  • trustedSequencer: EOA 1

Verifies ZK proofs for state roots of this Layer 2 via the PolygonRollupManager.

The shared bridge contract, escrowing user funds sent to Layer 2s perticipating in the AggLayer. It is mirrored on each L2 and can be used to transfer both ERC20 assets and arbitrary messages.

• Roles:
  • admin: SharedProxyAdmin; ultimately PolygonAdminMultisig
• This contract can store any token.

The central shared managing contract for Layer 2s on the Polygon AggLayer. This contract receives L2 state roots as well as ZK proofs. All connected Layer 2s can be globally paused by activating the ‘Emergency State’. This can be done by the PolygonSecurityCouncil or by anyone after 1 week of inactive verifiers.

• Roles:
  • admin: SharedProxyAdmin; ultimately PolygonAdminMultisig
  • createRollup: PolygonAdminMultisig, PolygonCreateRollupMultisig
  • defaultAdmin: Timelock; ultimately PolygonAdminMultisig
  • emergencyCouncilAdmin: PolygonSecurityCouncil
  • trustedAggregator: EOA 2, EOA 3
  • tweakParameters: PolygonAdminMultisig

A merkle tree storage contract aggregating state roots of each participating Layer 2, thus creating a single global merkle root representing the global state of the AggLayer, the ‘global exit root’. The global exit root is synchronized to all connected Layer 2s to help with their interoperability.

• Roles:
  • admin: SharedProxyAdmin; ultimately PolygonAdminMultisig

A timelock with access control. In the case of an activated emergency state in the PolygonRollupManager, all transactions through this timelock are immediately executable. The current minimum delay is 3d.

• Roles:
  • timelockAdmin: PolygonAdminMultisig (no delay if in emergency state), Timelock (no delay if in emergency state); ultimately PolygonAdminMultisig (no delay if in emergency state)

Custom Bridge escrow for DAI bridged to PolygonZkEVM allowing for a custom L2 tokens contract.

• Roles:
  • admin: Polygon zkEVM Multisig
• This contract stores the following tokens: DAI, sDAI.

Custom Bridge escrow for USDC bridged to PolygonZkEVM allowing for a custom L2 tokens contract.

• Roles:
  • admin: Polygon zkEVM Multisig
• This contract stores the following tokens: USDC.

Custom Bridge escrow for wstETH bridged to PolygonZkEVM allowing for a custom L2 tokens contract.

• Roles:
  • admin: Polygon zkEVM Multisig
• This contract stores the following tokens: wstETH.

• Roles:
  • owner: Timelock
