Forknet is live on mainnet, integrated with Agglayer. ## Risk summary ### Funds can be stolen if 1. the operator manipulates the L2 state, which is not validated on Ethereum, (CRITICAL) 2. a contract receives a malicious code upgrade. There is no delay on code upgrades (CRITICAL). ### Funds can be lost if 3. the accounting proof system for the bridge (pessimistic proofs, SP1) is implemented incorrectly. ## Risk analysis ### Sequencer failure Self sequence (sentiment: good) In the event of a sequencer failure, users can force transactions to be included in the project's chain by sending them to L1. There can be up to a 12h delay on this operation. ### State validation None (sentiment: bad) Currently the system permits invalid state roots. 'Pessimistic' proofs only validate the bridge accounting. ### Data availability Onchain (sentiment: good) All of the data needed for proof construction is published on Ethereum L1. ### Exit window None (sentiment: bad) There is no window for users to exit in case of an unwanted upgrade since contracts are instantly upgradable. ### Proposer failure Cannot withdraw (sentiment: bad) Only the whitelisted proposers can publish state roots on L1, so in the event of failure the withdrawals are frozen. ## Data availability ### Data is posted on Ethereum Transaction data is posted to Ethereum L1 as compressed calldata or blobs through the OP Stack batch inbox. ## Upgrades & Governance The regular upgrade process for shared system contracts and L2-specific validium contracts starts at the PolygonAdminMultisig. For the shared contracts, they schedule a transaction that targets the ProxyAdmin via the Timelock, wait for 3d and then execute the upgrade. An upgrade of the Layer 2 specific validium contract requires first adding a new rollupType through the Timelock and the AgglayerManager (defining the new implementation and verifier contracts). Now that the rollupType is created, either the local admin or the PolygonAdminMultisig can immediately upgrade the local system contracts to it. Chains using pessimistic proofs often have completely sovereign upgrade paths from the ones described here, but the shared contracts still remain relevant to them because they use them as escrow. The PolygonSecurityCouncil can expedite the upgrade process by declaring an emergency state. This state pauses both the shared bridge and the AgglayerManager and allows for instant upgrades through the timelock. Accordingly, instant upgrades for all system contracts are possible with the cooperation of the SecurityCouncil. The emergency state has been activated 1 time(s) since inception. Furthermore, the PolygonAdminMultisig is permissioned to manage the shared trusted aggregator (proposer and prover) for all participating Layer 2s, deactivate the emergency state, obsolete rollupTypes and manage operational parameters and fees in the AgglayerManager directly. The local admin of a specific Aggchain can manage their chain by choosing the trusted sequencer, manage forced batches and set the data availability config. For sovereign chains using pessimistic proofs they can manage any proof logic that might be used on top of the minimal pessimistic one. Creating new Layer 2s (of existing rollupType) is outsourced to the PolygonCreateRollupMultisig but can also be done by the PolygonAdminMultisig. Custom non-shared bridge escrows have their custom upgrade admins listed in the permissions section. ## Updates Shown as an interactive chart or widget on [the HTML page](https://l2beat.com/layer2s/projects/forknet#updates). ## Operator ### Users can force any transaction Because the state of the system is based on transactions submitted on the underlying host chain and anyone can submit their transactions there it allows the users to circumvent censorship by interacting with the smart contract on the host chain directly. ## Withdrawals ### Regular messaging The user initiates L2->L1 messages by submitting a regular transaction on this chain. When the block containing that transaction is settled, the message becomes available for processing on L1. ZK proofs are required to settle blocks. **References** - [AgglayerBridge.sol - source code, claimAsset function](https://etherscan.io/address/0x66E0120e3c965552a89AcC37b03f762624baC5Ad#code) ## Other considerations ### Shared bridge and Pessimistic Proofs Polygon Agglayer uses a shared bridge escrow for Rollups, Validiums and external chains that opt in to participate in interoperability. Each participating chain needs to provide zk proofs to access any assets in the shared bridge. In addition to the full execution proofs that are used for the state validation of Rollups and Validiums, accounting proofs over the bridges state (Polygon calls them 'Pessimistic Proofs') are used by external chains (cdk-erigon-sovereign and cdk-opgeth-sovereign variants). Using the SP1 zkVM by Succinct, even projects without a full proof system on Ethereum are able to share the bridge with any other Aggchain without adding additional trust assumptions. **Risks** - Funds can be lost if the accounting proof system for the bridge (pessimistic proofs, SP1) is implemented incorrectly. - Funds can be stolen if the operator manipulates the L2 state, which is not validated on Ethereum (CRITICAL). **References** - [Pessimistic Proof - Polygon Knowledge Layer](https://docs.polygon.technology/cdk/concepts/pessimistic-proofs) - [Etherscan: AgglayerManager.sol - verifyPessimisticTrustedAggregator() function](https://etherscan.io/address/0x15cAF18dEd768e3620E0f656221Bf6B400ad2618#code#F1#L1300) ## Permissions ### Ethereum #### Actors ##### PolygonAdminMultisig Addresses: [0x242daE44F5d8fb54B198D03a94dA45B5a4413e21](https://etherscan.io/address/0x242daE44F5d8fb54B198D03a94dA45B5a4413e21) A Multisig with 5/9 threshold. * Can upgrade **with 3d delay** * AgglayerGateway [via: Timelock with 3d delay (no delay if in emergency state) → SharedProxyAdmin] * AgglayerBridge [via: Timelock with 3d delay (no delay if in emergency state) → SharedProxyAdmin] * AgglayerManager [via: Timelock with 3d delay (no delay if in emergency state) → SharedProxyAdmin] * AgglayerGER [via: Timelock with 3d delay (no delay if in emergency state) → SharedProxyAdmin] * Can interact with AgglayerGateway * add new routes from proof selector to verifier / pessimisticVkey for pessimistic proofs **with 3d delay** [via: Timelock with 3d delay (no delay if in emergency state)] * add or update default aggchain verification keys (aggchainVkey) for any given selectors * change the aggchainSigners and threshold (a multisig used for permissioned state transitions) * freeze routes from proof selector to verifier / pessimisticVkey for pessimistic proofs * Can interact with AgglayerBridge * upgrade the implementation of wrapped tokens deployed by the bridge **with 3d delay** [via: Timelock with 3d delay (no delay if in emergency state)] * Can interact with AgglayerManager * deploy new projects that use predefined rollup types (implementations) and connect them or other Agglayer chains to the PolygonRollupManager * manage all access control roles, add new rollup types (which are implementation contracts that can then be upgraded to by connected projects), update any connected projects to new rollup types, migrate to pessimistic proofs and rollback batches, connect existing rollups to the PolygonRollupManager **with 3d delay** [via: Timelock with 3d delay (no delay if in emergency state)] * manage parameters like fees for all connected projects, set the trusted aggregator, stop the emergency state, update projects and obsolete rollup types * Can interact with Timelock * propose, cancel and execute transactions in the timelock, manage all access control roles and change the minimum delay **with 6d delay or with 3d delay** [via: Timelock with 3d delay (no delay if in emergency state) with 3d delay (no delay if in emergency state) - or - acting directly with 3d delay (no delay if in emergency state)] ##### Conduit Multisig 1 Addresses: [0x4a4962275DF8C60a80d3a25faEc5AA7De116A746](https://etherscan.io/address/0x4a4962275DF8C60a80d3a25faEc5AA7De116A746) A Multisig with 4/11 threshold. * Can upgrade **with no delay** * DelayedWETH [via: ProxyAdmin] * SuperchainConfig [via: ProxyAdmin] * OptimismMintableERC20Factory [via: ProxyAdmin] * SystemConfig [via: ProxyAdmin] * L1StandardBridge [via: ProxyAdmin] * DisputeGameFactory [via: ProxyAdmin] * L1CrossDomainMessenger [via: ProxyAdmin] * L1ERC721Bridge [via: ProxyAdmin] * OptimismPortal2 [via: ProxyAdmin] * AnchorStateRegistry [via: ProxyAdmin] * Can interact with AddressManager * set and change address mappings [via: ProxyAdmin] * Can interact with SystemConfig * it can update the preconfer address, the batch submitter (Sequencer) address and the gas configuration of the system ##### AgglayerManager Addresses: [0x5132A183E9F3CB7C848b0AAC5Ae0c4f0491B7aB2](https://etherscan.io/address/0x5132A183E9F3CB7C848b0AAC5Ae0c4f0491B7aB2) The central shared managing contract for Polygon Agglayer chains.
