# X Layer Markdown version of https://ethbeat.org/layer2s/projects/xlayer ## Summary **Warning:** Why is the project listed in others? There are less than 5 external actors that can submit challenges. Consequence: projects without a sufficiently decentralized set of challengers rely on few entities to safely update the state. A small set of challengers can collude with the proposer to finalize an invalid state, which can cause loss of funds.

X Layer activates OP Succinct Lite to resolve challenged OP Stack state proposals with ZK proofs. - 2025-08-05: [Migration to Pessimistic Proofs](https://etherscan.io/tx/0xab579dbf426db0badfaef925504105088f3300b51f1362a4084c57d7e13c0fb1#eventlog). X Layer stops validating the full L2 state and moves to bridge accounting proofs. - 2024-04-16: [X Layer Public Launch](https://x.com/XLayerOfficial/status/1780056275898048562). X Layer is live on mainnet, integrated with Agglayer. ## Risk summary ### Funds can be stolen if 1. a contract receives a malicious code upgrade. There is no delay on code upgrades (CRITICAL), 2. the validity proof cryptography is broken or implemented incorrectly, 3. no whitelisted challenger disputes an invalid state root before the challenge window expires, 4. the SP1 verifier gateway owner routes proof verification through a malicious or faulty verifier. ### Funds can be lost if 5. the Agglayer pessimistic proof system for shared bridge accounting is implemented incorrectly. ### Funds can be frozen if 6. the OP Succinct Lite proof system or verifier gateway cannot accept valid proofs during a challenge, 7. the permissioned proposer fails to publish state roots to L1. ## Risk analysis ### Sequencer failure Self sequence (12h delay; 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 Fraud proofs (1R, ZK) (1h challenge period + 3d 12h execution delay; sentiment: bad) Fraud proofs allow actors watching the chain to prove that the state is incorrect. Single round proofs (1R) only require a single transaction to resolve. ZK proofs are used to prove the correctness of the state transition. Challenges are currently restricted to 1 whitelisted challenger and proposals are restricted to 1 whitelisted proposer. ### 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 whitelisted proposers can publish state roots. Permissionless proposing becomes available only after 1000y of proposer inactivity, which is not a practical recovery path. ## 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. Learn more about the DA layer here: [Ethereum](https://ethbeat.org/projects/ethereum) ## State validation ### Fraud proofs State roots are proposed by whitelisted proposers who create dispute games via the DisputeGameFactory by posting a bond of 0.00000001 ETH. Once created, the game enters a challenge period of 1h during which whitelisted challengers can dispute the proposal by posting a bond of 0.00000001 ETH. If challenged, anyone can submit a ZK proof to prove the correct state within the proving period of 7d. After the challenge period passes without a successful challenge, or after a valid proof is submitted, anyone can resolve the game and finalize the state root. **Risks** - Funds can be stolen if the validity proof cryptography is broken or implemented incorrectly. - Funds can be stolen if no whitelisted challenger disputes an invalid state root before the challenge window expires. - Funds can be stolen if the SP1 verifier gateway owner routes proof verification through a malicious or faulty verifier. - Funds can be frozen if the permissioned proposer fails to publish state roots to L1. **References** - [OP Succinct Lite architecture](https://succinctlabs.github.io/op-succinct/fault_proofs/fault_proof_architecture.html) - [OPSuccinctFaultDisputeGame.sol - Etherscan source code](https://etherscan.io/address/0x8841FA06099FEdfE7DB6962926C6A281e9E1e607#code) - [SP1VerifierGateway.sol - Etherscan source code](https://etherscan.io/address/0x3B6041173B80E77f038f3F2C0f9744f04837185e#code) ### Prover: [SP1 Hypercube](https://ethbeat.org/zk-catalog/sp1hypercube) #### Trusted setups - Gnark (Plonk): - Aztec Ignition, risk green (lowest risk) per the [Trusted Setups Risk Framework](https://forum.l2beat.com/t/the-trusted-setups-framework-for-zk-catalog/381): Aztec Ignition is a trusted setup ceremony that was run by Aztec for KZG commitment over BN254 curve in 2019.

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.

The previous rollupType was 4. ### [2024-04-25 09:16 UTC](https://ethbeat.org/layer2s/projects/xlayer?update=701fd5fe) (1 change) The contract (`PolygonValidiumStorageMigration.sol`, here `XLayerValidiumEtrog`) was already diff'd to Astar by Luca (0 diff). ### [2024-04-23 12:14 UTC](https://ethbeat.org/layer2s/projects/xlayer?update=ed033ddb) (8 changes) New Validium. There is no diff with Astar zkEVM. ## 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 ### Agglayer shared bridge and OP Stack state validation X Layer uses OP Stack dispute games for state validation and withdrawal finalization. Separately, the Agglayer shared bridge uses pessimistic proofs to constrain cross-chain bridge accounting for assets in the shared bridge. **Risks** - Funds can be lost if the Agglayer pessimistic proof system for shared bridge accounting is implemented incorrectly. - Funds can be frozen if the OP Succinct Lite proof system or verifier gateway cannot accept valid proofs during a challenge. **References** - [Pessimistic Proof - Polygon Knowledge Layer](https://docs.polygon.technology/cdk/concepts/pessimistic-proofs) ## Permissions Explore these contracts and permissions in Disco, ETHBEAT's contract explorer: https://disco.l2beat.com/ui/p/xlayer ### Ethereum #### Actors ##### PolygonAdminMultisig Addresses: [0x242daE44F5d8fb54B198D03a94dA45B5a4413e21](https://etherscan.io/address/0x242daE44F5d8fb54B198D03a94dA45B5a4413e21) A Multisig with 5/9 threshold. -
