# GRVT Markdown version of https://ethbeat.org/layer2s/projects/grvt ## Summary **Warning:** Why is the project listed in others? There is no data availability bridge. Consequence: projects without a data availability bridge fully rely on single entities (the sequencer) to honestly rely available data roots on Ethereum. A malicious sequencer can collude with the proposer to finalize an unavailable state, which can cause loss of funds.

GRVT mainnet alpha launches for all users. ## Risk summary **Warning:** 1 address has unverified source code (CRITICAL). - 0x67fB799C70ee1Ecbc015AcB25F0BA8E77F20F251 ### Funds can be stolen if 1. a contract receives a malicious code upgrade. There is a 4d 3h - 8d 3h delay on code upgrades unless upgrade is initiated by the EmergencyUpgradeBoard in which case there is no delay, 2. the source code of unverified contracts contains malicious code (CRITICAL). ### Funds can be lost if 3. the external data becomes unavailable (CRITICAL), 4. the proof system is implemented incorrectly. ### Users can be censored if 5. the operator refuses to include their transactions, 6. the Operator does not specifically whitelist them in the TransactionFilterer. ### MEV can be extracted if 7. the operator exploits their centralized position and frontruns user transactions. ## Risk analysis **Warning:** 1 address has unverified source code (CRITICAL). - 0x67fB799C70ee1Ecbc015AcB25F0BA8E77F20F251 ### Sequencer failure No mechanism (sentiment: bad) There is no mechanism to have transactions be included if the sequencer is down or censoring. The Operator actively uses a TransactionFilterer contract, which requires accounts that enqueue or force transactions from L1 to be whitelisted. ### State validation Validity proofs (ST, SN) (3h execution delay; sentiment: good) STARKs and SNARKs are zero knowledge proofs that ensure state correctness. STARKs proofs are wrapped in SNARKs proofs for efficiency. SNARKs require a trusted setup. ### Data availability External (sentiment: bad) Proof construction and state derivation rely fully on data that is NOT published onchain. ### Exit window None (emergency upgrade path; sentiment: bad); 4d 3h (regular upgrade path; sentiment: warning) Non-emergency upgrades go through a 4d 3h delay, but the central operator can still censor withdrawal transactions by implementing a TransactionFilterer with no delay. There is no window for users to exit in case of an unwanted upgrade since contracts are instantly upgradable. ### Proposer failure Replace proposer (sentiment: warning) Only the whitelisted proposers can publish state roots on L1, so in the event of failure the withdrawals are frozen. There is a decentralized Governance system that can attempt changing Proposers with an upgrade. ## Stage GRVT is not even a Stage 0 project. ### Stage 0 4 requirements met. - Met: The project self-identifies as a Validium or Optimium. - Met: State roots are posted to Ethereum L1. - Met: A complete and functional proof system (fraud or validity proofs) is deployed. - Met: A source-available node exists that can reconstruct the L2 state when DA is accessible. Please note that the ETHBEAT team has not verified the validity of the node source code. [View code](https://github.com/matter-labs/zksync-era) ### Stage 1 4 issues need fixing. **Principle** - Issue: Compromising ≥75% of the Security Council to push a malicious upgrade, or sequencer+DA-committee collusion to withhold data and finalize invalid state roots, should be the only ways (other than bugs) to steal funds or block withdrawals indefinitely. **Guidelines** - Met: The proof system meets the minimum trusted setup requirements defined in the ETHBEAT [trusted setup assessment framework](https://forum.l2beat.com/t/the-trusted-setups-framework-for-zk-catalog/381). - Met: Prover source code is published. - Met: The sources of all programs used are public and program hashes can be independently regenerated. - Issue: Users' withdrawals can be censored by the permissioned operators. - Issue: Upgrades executed by actors with more centralized control than a Security Council provide less than 7d for users to exit if the permissioned operator is down or censoring. - Issue: The Security Council is not properly set up. [Learn more about Stages](https://ethbeat.org/stages). Please keep in mind that these stages do not reflect project security, this is an opinionated assessment of project maturity based on subjective criteria, created with a goal of incentivizing projects to push toward better decentralization. Each team may have taken different paths to achieve this goal. ## Data availability ### Data is not stored on chain The transaction data is not recorded on the Ethereum main chain. Transaction data is stored off-chain and only the hashes are posted onchain by the centralized Sequencer. **Risks** - Funds can be lost if the external data becomes unavailable (CRITICAL). **References** - [ExecutorFacet - _commitOneBatch() function](https://etherscan.io/address/0x0597CaA8A823A699d7CD9E62B5E5d4153FF82691#code#F1#L50) ## State validation Each update to the system state must be accompanied by a ZK proof that ensures that the new state was derived by correctly applying a series of valid user transactions to the previous state. These proofs are then verified on Ethereum by a smart contract. ### Prover Architecture ZKsync Era proof system Boojum can be found [here](https://github.com/matter-labs/era-boojum/tree/main) and contains essential tools like the Prover, the Verifier, and other backend components. The specs of the system can be found [here](https://github.com/matter-labs/zksync-era/tree/main/prover). ### ZK Circuits ZKsync Era circuits are built from Boojum and are designed to replicate the behavior of the EVM. The source code can be found [here](https://github.com/matter-labs/era-zkevm_circuits/tree/main). The circuits are checked against tests that can be found [here](https://github.com/matter-labs/era-zkevm_test_harness/tree/main). **Risks** - Funds can be lost if the proof system is implemented incorrectly. ### Verification Keys Generation SNARK verification keys can be generated and checked against the Ethereum verifier contract using [this tool](https://github.com/matter-labs/zksync-era/tree/main/prover/crates/bin/vk_setup_data_generator_server_fri). The system requires a trusted setup. ### Prover: [Boojum](https://ethbeat.org/zk-catalog/boojum) #### Trusted setups - Bellman (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.

Install npm and yarn: `npm install --global yarn` 2. Install hardhat: `npm install -g hardhat` 3. Install foundry-zksync: `curl -L https://raw.githubusercontent.com/matter-labs/foundry-zksync/main/install-foundry-zksync | bash` from [here](https://foundry-book.zksync.io/introduction/installation/). Verify: 1. Checkout the correct branch in [era-contracts](https://github.com/matter-labs/era-contracts) repo: `git checkout v0.29.2`. Commit hash should be `dbfc9b5a40d68007dc405a9b669230104c1646e4`. 2. Execute recompute_hashes.sh script: `chmod +x recompute_hashes.sh` and `./recompute_hashes.sh`. Note that the script may require a specific version of `foundryup-zksync` and it will suggest the command to install it. However you might need to manually clear git working tree in the repo foundry-zksync (probably in ~/.foundry/matter-labs/foundry-zksync) to change versions. ## Upgrades & Governance ![A diagram of the upgrades and governance](https://ethbeat.org/static/images/upgrades-and-governance/zkstack.1d46dba7.png) There are two main paths for contract upgrades in the shared ZK stack ecosystem - standard and emergency - both converging on the shared upgrade management contract ProtocolUpgradeHandler. The standard path involves a governance proposal and voting through the DAO, multiple timelock delays and finally approval by the Guardians or 4 SecurityCouncil participants. The emergency path allows for contract upgrades without any delay by the EmergencyUpgradeBoard, which acts as a 3/3 Multisig between SecurityCouncil, Guardians and the FoundationMultisig. ### Standard path #### On ZKsync Era Delegates can start new proposals by reaching a threshold of 21M ZK tokens on the ZKsync Era Rollup's ZkProtocolGovernor contract. This launches a 3d 'voting delay' after which the 7d voting period starts. During these first two periods, the proposal can be canceled by the proposer or if it falls below the proposing threshold. A proposal is only successful if it reaches both quorum (630M ZK tokens) and simple majority. When it reaches quorum, a remaining voting period of 3d is guaranteed by a potential late quorum vote extension. In the successful case, it can be queued in the 0s timelock which forwards it via the Gateway to Ethereum as an L2->L1 log. #### On Ethereum After the execution of the proposal-containing batch (3h delay), the proposal is now picked up by the ProtocolUpgradeHandler and enters the 3d 'legal veto period'. This serves as a window in which a veto could be coordinated offchain, to be then enforced by non-approval of Guardians and SecurityCouncil. A threshold of 2 Guardians can extend the veto period to 7d. After this a proposal enters a *waiting* state of 1mo, from which it can be immediately approved (cancelling the delay) by 4 participants of the SecurityCouncil. For the unlikely case that the Security Council does not approve here, the Guardians can instead approve the proposal, or nobody. In the two latter cases, the waiting period is enforced in full. A proposal cannot be actively cancelled in the ProtocolUpgradeHandler, but will expire if not approved within the waiting period. An approved proposal now enters the *pendingExecution* state for a final delay of 1d and can then be executed. #### Other governance tracks There are two other tracks of Governance also starting with DAO Delegate proposals the ZKsync Era rollup: 1) Token Program Proposals that add new minters, allocations or upgrade the ZK token and 2) Governance Advisory Proposals that e.g. change the ZK Credo or other offchain Governance Procedures without onchain targets. The protocol for these two other tracks is similar to the first part of the standard path described above (albeit having different quorum and timelock values), and not passing over to the Ethereum L1. Further customizations are that the ZkFoundationMultisig can propose to the ZkTokenGovernor without a threshold and that the Guardians' L2 alias can cancel proposals in the ZkTokenGovernor and the ZkGovOpsGovernor. ### Emergency path SecurityCouncil (6/8), Guardians (5/8) and ZkFoundationMultisig (3/6) form a de-facto 3/3 Multisig by pushing an immediate upgrade proposal through the EmergencyUpgradeBoard, which circumvents all delays and executes immediately via the ProtocolUpgradeHandler. ### Upgrade Delays The cumulative duration of the upgrade paths from the moment of a voted 'successful' proposal is 4d 3h or 8d 3h (depending on Guardians extending the LegalVetoPeriod) for Standard, 0 for Emergency and 1mo 4d for the path in which the SecurityCouncil is not approving the proposal. ### Freezing The SecurityCouncil can freeze (pause withdrawals and settlement) all chains connected to the current ChainTypeManager. Either for a softFreeze of 12h or a hardFreeze of 7d. After a softFreeze and / or a hardFreeze, a proposal from the EmergencyUpgradeBoard has to be passed before subsequent freezes are possible. Only the SecurityCouncil can unfreeze an active freeze. ### ZK cluster Admin and Chain Admin Apart from the paths that can upgrade all shared implementations, the ZK stack governance system defines other roles that can modify the system: A single *ZK cluster Admin* role who governs parameters in the shared contracts and a *Chain Admin* role (defined in each chain-specific diamond contract) for managing parameters of each individual ZK chain that builds on the stack. These chain-specific actions include critical operations like setting a transaction filterer that can censor L1 -> L2 messages, changing the DA mode, migrating the chain to a different settlement layer and standard operations like setting fee parameters and adding / removing Validators in the ValidatorTimelock. For rollups, data availability on Ethereum is validated by a RollupL1DAValidator contract (or a RelayedSLDAValidator on the Gateway). Each rollup can become a permanent rollup (through their Chain Admin) which disallows DA changes to non-whitelisted sources or settlement layers in the future. The source of truth for rollup-compliant DA validator contracts is the RollupDAManager contract, which is administered via the ProtocolUpgradeHandler. ZKsync Era's Chain Admin differs from the others as it also has the above *ZK cluster Admin* role in the shared ZK stack contracts. ### Past upgrades The metrics include upgrades on the currently used proxy contracts.

The GRVT chain itself is unchanged and still on protocol 0.30.1; the v31 diamond cut is staged in the EraChainTypeManager but not applied yet. GrvtChainAdminMultisig set itself as the withdrawalRecipient of the YieldRecipientTreasury (https://etherscan.io/tx/0xab5133ebba9d89d7a63a5b347c1ab106a0f7cad4b9335b45439d96f9db93cba3), replacing the 3/6 Safe 0xcE7a…23Ca, which left the discovery together with its deployer EOA; harvested yield now goes to the chain admin multisig. The strategy balances of the GRVTL1TreasuryVault are no longer watched. ### [2026-11-02 11:06 UTC](https://ethbeat.org/layer2s/projects/grvt?update=4e921229) (high severity, 84 changes) GRVTBridgeProxy upgraded (https://disco.l2beat.com/diff/eth:0x7F9FCdaf7f65Fd5737De61d8bF5617A9AA8cFaF1/eth:0x8bc3249fEc4f61440Af91Ea2F3506F156039297C): a new `depositFromCompartment()` lets contracts registered in the new CompartmentRegistry deposit to GRVT without a DepositApprover signature, only to the L2 deposit proxy of their vault. Compartments hold capital of GRVT vaults withdrawn to Ethereum and deploy it into Axcess, Nest and Wildcat venues. Added the GRVTL1TreasuryVault (Grvt Yield Layer) with its yield strategies, that existed before but was not tracked. The exchange withdraws most of its reserves from the shared bridge to this vault, which invests them in Aave, sGHO and USDY, without any user control. ### [2026-10-23 10:17 UTC](https://ethbeat.org/layer2s/projects/grvt?update=59f8be76) (2 changes) Governance approved proposal that sends trxs to L2: https://tools.l2beat.com/decoder-new/?hash=0x301cafca68144cabff26ffe4007100c05ef451203bf461840acd2756ddc0f27d&data=AwA. ### [2026-10-16 09:49 UTC](https://ethbeat.org/layer2s/projects/grvt?update=f81237dd) (2 changes) Governance executed an L2 transaction on GRVT through the Bridgehub: https://tools.l2beat.com/decoder-new/?hash=0x6ecfb2cc39c3522d22e1083b402bbcd494385f32fe69e6615608b59a1f66d1a1&data=AwA. ### [2026-10-13 13:06 UTC](https://ethbeat.org/layer2s/projects/grvt?update=77df2404) (2 changes) Governance proposal to execute some L2 upgrade: https://tools.l2beat.com/decoder-new/?hash=0xc5846160840110f972ee0542b77cdf5744a3d374f58a308ded4b1de12b12131f&data=AwA. ### [2026-10-02 12:40 UTC](https://ethbeat.org/layer2s/projects/grvt?update=74029814) (high severity, 16 changes) Executed this proposal: https://www.tally.xyz/gov/zksync/proposal/49883493212277767948924829453899549013679463473253620701602979414799679547598?govId=eip155%3A324%3A0x76705327e682F2d96943280D99464Ab61219e34f. Now each chain admin can increase the execution delay of its chain (`increaseChainExecutionDelay`), the owner can set it freely (`setChainExecutionDelay`). The effective delay for GRVT is tracked in `executionDelayGRVT` (still 3h). Also adds a new `UPGRADER_ROLE` that can call `upgradeChainFromVersion()` through the VTL (forwarded to the diamond). Currently nobody holds the role for GRVT yet (tracked in `upgraderVTL`). ### [2026-09-04 13:45 UTC](https://ethbeat.org/layer2s/projects/grvt?update=cc5f6a14) (high severity, 5 changes) Governance proposal executed: https://tools.l2beat.com/decoder-new/?hash=0x91b14e9960db6c886e6b0294122f0c5b08398b371f83c83072cab0a00c3c153a&data=AwA.

A live and trustworthy operator is vital to the health of the system. **Risks** - MEV can be extracted if the operator exploits their centralized position and frontruns user transactions. ### Users can't force all transactions If a user is censored by the L2 Sequencer, they cannot by default force their transaction via the L1 queue. An active TransactionFilterer contract which allows only whitelisted accounts to enqueue, prevents it. Even if a user was specifically whitelisted, there is no mechanism that forces L2 Sequencer to include transactions from the queue in an L2 block, as they have the choice to process the queue in order or not at all. **Risks** - Users can be censored if the operator refuses to include their transactions. - Users can be censored if the Operator does not specifically whitelist them in the TransactionFilterer. **References** - [L1 - L2 interoperability - Developer's documentation](https://docs.zksync.io/zksync-protocol/rollup/l1_l2_communication#priority-operations-1) - [Mailbox facet](https://etherscan.io/address/0x1e34aB39a9682149165ddeCc0583d238A5448B45#code#F1#L472) - [TransactionFilterer](https://etherscan.io/address/0x8319fede99061c6723c86d366a903e8fa3a0f541#code#F1#L29) ## 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** - [Withdrawing funds - ZKsync documentation](https://docs.zksync.io/zksync-protocol/rollup/bridging-assets) ### Forced messaging If the user experiences censorship from the operator with regular L2->L1 messaging they can submit their messages directly on L1. The system is then obliged to service this request or halt all messages from L1, including all forced withdrawals and deposits. Once the force operation is submitted and if the request is serviced, the operation follows the flow of a regular message. ## Permissions Explore these contracts and permissions in Disco, ETHBEAT's contract explorer: https://disco.ethbeat.org/ui/p/grvt ### Ethereum #### Actors ##### EmergencyUpgradeBoard Addresses: [0x91989F9BB8391D3471D2672Ec001921cB14C4b7C](https://etherscan.io/address/0x91989F9BB8391D3471D2672Ec001921cB14C4b7C) A custom contract allowing a 3/3 of SecurityCouncil, ZK Foundation Multisig and Guardians to `executeEmergencyUpgrade()` via the ProtocolUpgradeHandler. -

There is a 4d 3h - 8d 3h delay on code upgrades unless upgrade is initiated by the EmergencyUpgradeBoard in which case there is no delay. - Funds can be stolen if the source code of unverified contracts contains malicious code (CRITICAL). ### Program Hashes #### Boojum L2 Bootloader program v0.29.2 EraVM program that proves the correct execution of a batch of ZK Stack L2 blocks. - Hash: `0x01000911c4db4fe62c98e180cfa7e9b3a22fb15f505905d4bf36192f481551e6` - Repository: https://github.com/matter-labs/era-contracts/blob/v0.29.2/system-contracts/bootloader/bootloader.yul - Verification: successful - Used in: [ZKsync Era](https://ethbeat.org/layer2s/projects/zksync-era), [Cronos zkEVM](https://ethbeat.org/layer2s/projects/cronoszkevm), [Abstract](https://ethbeat.org/layer2s/projects/abstract), [Sophon](https://ethbeat.org/layer2s/projects/sophon), [Lens](https://ethbeat.org/layer2s/projects/lens), [GRVT](https://ethbeat.org/layer2s/projects/grvt), [ZERO Network](https://ethbeat.org/layer2s/projects/zeronetwork), [zkCandy](https://ethbeat.org/layer2s/projects/zkcandy) ##### Verification steps Prepare: 1. Install npm and yarn: `npm install --global yarn` 2. Install hardhat: `npm install -g hardhat` 3. Install foundry-zksync: `curl -L https://raw.githubusercontent.com/matter-labs/foundry-zksync/main/install-foundry-zksync | bash` from [here](https://foundry-book.zksync.io/introduction/installation/). Verify: 1. Checkout the correct branch in [era-contracts](https://github.com/matter-labs/era-contracts) repo: `git checkout v0.29.2`. Commit hash should be `dbfc9b5a40d68007dc405a9b669230104c1646e4`. 2. Execute recompute_hashes.sh script: `chmod +x recompute_hashes.sh` and `./recompute_hashes.sh`. Note that the script may require a specific version of `foundryup-zksync` and it will suggest the command to install it. However you might need to manually clear git working tree in the repo foundry-zksync (probably in ~/.foundry/matter-labs/foundry-zksync) to change versions.
