# Funki

Markdown version of https://l2beat.com/layer2s/projects/funki

## Summary

**Warning:** Why is the project listed in others? The proof system isn't fully functional. Consequence: projects without a proper proof system fully rely on single entities to safely update the state. A malicious proposer can finalize an invalid state, which can cause loss of funds. 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.

## Risk summary

**Warning:** The project relies on program hashes that could not be successfully reproduced from their published sources (CRITICAL).

**Warning:** The fault proof system is deployed but is not functional. The dispute game commits to the placeholder absolute prestate from the OP Stack deployment template rather than to a reproducible op-program build for this chain. Security relies entirely on the permissioned proposer and challengers.

### Funds can be stolen if

1. the sequencer is malicious and is able to economically outspend the altruistic challengers,
2. there is no challenger willing to challenge unavailable data commitments,
3. a contract receives a malicious code upgrade. There is no delay on code upgrades (CRITICAL),
4. no whitelisted challenger disputes an invalid state root before the challenge window expires (CRITICAL).

### MEV can be extracted if

5. the operator exploits their centralized position and frontruns user transactions.

## Risk analysis

**Warning:** The fault proof system is deployed but is not functional. The dispute game commits to the placeholder absolute prestate from the OP Stack deployment template rather than to a reproducible op-program build for this chain. Security relies entirely on the permissioned proposer and challengers.

### 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 (INT) (3d 12h challenge period + 3d 12h execution delay; sentiment: bad)

Fraud proofs allow actors watching the chain to prove that the state is incorrect. Interactive proofs (INT) require multiple transactions over time to resolve. Only one entity is currently allowed to propose and submit challenges, as only permissioned games are currently allowed.

### Data availability

External (sentiment: bad)

Proof construction and state derivation rely fully on data that is NOT published onchain. A custom data availability (DA) provider without attestations is used, but data unavailability can be challenged.

### 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.

## Stage

Funki is not even a Stage 0 project.

**Warning:** The requirement for available node software is under review.

### Stage 0

1 issue needs fixing.

- 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.
- Under review: A source-available node exists that can reconstruct the L2 state when DA is accessible. Please note that the L2BEAT team has not verified the validity of the node source code.
- Issue: Fraud proof submission is not sufficiently decentralized.

### 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**

- 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: Not all program sources are public or not all program hashes can be independently regenerated.

[Learn more about Stages](https://l2beat.com/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

Altlayer DA is a data availability solution using data availability challenges (DA Challenges).

### Risk analysis

#### Economic security

DA Challenges (sentiment: bad)

There are no onchain assets at risk of being slashed in case of a data withholding attack. However, there is a mechanism that allows users to challenge unavailability of data. The system is not secure if the malicious sequencer is able to outspend the altruistic challengers, and there is no pool of funds onchain to incentivize challengers.

#### Fraud detection

None (sentiment: bad)

There is no fraud detection mechanism in place. A data withholding attack can only be detected by nodes downloading the full data from the DA layer.

#### Committee security

None (sentiment: bad)

The committee does not meet basic security standards, either due to insufficient size, lack of member diversity, or poorly defined threshold parameters. The system lacks an effective DA bridge and it is reliant on the assumption of an honest sequencer, creating significant risks to data integrity and availability.

#### Upgradeability

No delay (sentiment: bad)

There is no delay in the upgradeability of the bridge. Users have no time to exit the system before the bridge implementation update is completed.

#### Relayer failure

No mechanism (sentiment: bad)

The relayer role is permissioned, and the DA bridge does not have a Security Council or a governance mechanism to propose new relayers. In case of relayer failure, the DA bridge will halt and be unable to recover without the intervention of a centralized entity.

### Technology

#### Architecture
![gmnetworkDA layer](https://l2beat.com/images/da-layer-technology/gmnetworkda/architecture.png#center)

#### Data Availability Challenges
The project relies on DA challenges for data availability.
The DA Provider submits an input commitment on Ethereum, and users can request the data behind the commitment off-chain from the DA Provider.
If a DA challenger finds that the data behind a tx data commitment is not available, they can submit a challenge which requires locking a bond within 12h.
A challenge can be resolved by publishing the preimage data within an additional 12h.
In such case, a portion of the challenger bond is burned, with the exact amount estimated as the cost incurred by the resolver to publish the full data, meaning that the resolver and challenger will approximately lose the same amount of funds.
The system is not secure if the malicious sequencer is able to outspend the altruistic challengers.
If instead, after a challenge, the preimage data is not published, the chain reorgs to the last fully derivable state.

#### DA Bridge
Only hashes of data batches are posted as DA commitments to an EOA on Ethereum.
However, there is a mechanism that allows users to challenge unavailability of data.

**Risks**

- Funds can be lost if the sequencer posts an invalid data availability certificate and there are no challengers.
- Funds can be lost if the sequencer posts an invalid data availability certificate, and he is able to outspend the challengers.

## State validation

Updates to the system state can be proposed and challenged by permissioned operators only. If a state root passes the challenge period, it is optimistically considered correct and made actionable for withdrawals.

### State root proposals

Proposers submit state roots as children of the latest confirmed state root (called anchor state), by calling the `create` function in the DisputeGameFactory. A state root can have multiple conflicting children. Each proposal requires a stake, currently set to 0.0 ETH, that can be slashed if the proposal is proven incorrect via a fraud proof. Stakes can be withdrawn only after the proposal has been confirmed. A state root gets confirmed if the challenge period has passed and it is not countered.

**Risks**

- Funds can be stolen if no whitelisted challenger disputes an invalid state root before the challenge window expires (CRITICAL).

### Challenges

Challenges are opened to disprove invalid state roots using bisection games. Each bisection move requires a stake that increases expontentially with the depth of the bisection, with a factor of 1.09493. The maximum depth is 73, and reaching it therefore requires a cumulative stake of 0.00 ETH from depth 0. Actors can participate in any challenge by calling the `defend` or `attack` functions, depending whether they agree or disagree with the latest claim and want to move the bisection game forward. Actors that disagree with the top-level claim are called challengers, and actors that agree are called defenders. Each actor might be involved in multiple (sub-)challenges at the same time, meaning that the protocol operates with [full concurrency](https://medium.com/l2beat/fraud-proof-wars-b0cb4d0f452a). Challengers and defenders alternate in the bisection game, and they pass each other a clock that starts with 3d 12h. If a clock expires, the claim is considered defeated if it was countered, or it gets confirmed if uncountered. Since honest parties can inherit clocks from malicious parties that play both as challengers and defenders (see [freeloader claims](https://specs.optimism.io/fault-proof/stage-one/fault-dispute-game.html#freeloader-claims)), an inherited clock with too little time remaining is generally extended by 3h. The extension is 6h when the next claim is immediately before split depth 30, and 1d 3h (the standard extension plus the 1d oracle challenge period) immediately before the last depth. Along a full-depth path, cumulative extensions can therefore add up to 10d 3h. Since unconfirmed state roots are independent of one another, users can decide to exit with a subsequent confirmed state root if the previous one is delayed. Winners get the entire losers' stake, meaning that sybils can potentially play against each other at no cost. The final instruction found via the bisection game is then executed onchain in the MIPS one step prover contract who determines the winner. The protocol does not enforce valid bisections, meaning that actors can propose correct initial claims and then provide incorrect midpoints. The protocol can be subject to resource exhaustion attacks ([Spearbit 5.1.3](https://github.com/ethereum-optimism/optimism/blob/develop/docs/security-reviews/2024_08_Fault-Proofs-No-MIPS_Spearbit.pdf)).

### [2026-09-30 22:44 UTC](https://l2beat.com/layer2s/projects/funki?update=5e1c26a8) (high severity, 10 changes)

OP Contracts Upgrade 20 (op-contracts/v8.0.0-rc.3): the shared SuperchainConfig implementation was upgraded v2.4.2 → v2.4.3 on 2026-09-24. Version bump only; no chain-specific contract changed. ([diff](https://disco.l2beat.com/diff/eth:0xE4F9779ab53070a55db24dFAeFf9AF147c6ED550/eth:0x5570b1f2b97B1E35b5C6f9Ee76f6cf02c9917504))

### [2026-09-10 12:47 UTC](https://l2beat.com/layer2s/projects/funki?update=6f479007) (1 change)

Optimism Security Council: Member rotated.

### [2026-08-04 21:26 UTC](https://l2beat.com/layer2s/projects/funki?update=555cd99d) (6 changes)

Guardian intervention by the operator: a resolved PermissionedDisputeGame proposal (`0x586a…77ef`) was blacklisted on the OptimismPortal2 and the AnchorStateRegistry anchor was reset from a separate, valid game. Since the guardian role is derived from the Superchain-wide SuperchainConfig, both contracts were temporarily upgraded to `SuperchainConfigSetter` implementations pointing `superchainConfig` at an operator-controlled deployment; minutes later the pointer and original implementations were restored.

### [2026-07-17 10:08 UTC](https://l2beat.com/layer2s/projects/funki?update=00fb76c9) (2 changes)

OpFoundation shared Safes (UpgradeSafe + OperationsSafe): 2 members rotated.

### [2026-07-06 07:55 UTC](https://l2beat.com/layer2s/projects/funki?update=55e15a71) (high severity, 12 changes)

Shared SuperchainConfig upgraded 2.4.0 → 2.4.2 ([diff](https://disco.l2beat.com/diff/eth:0xb08Cc720F511062537ca78BdB0AE691F04F5a957/eth:0xE4F9779ab53070a55db24dFAeFf9AF147c6ED550)). No behavioral change — `ProxyAdminOwnedBase` import moved, misleading pause-state warning removed, and 5 new unused constants added to the shared `Constants` library (forward-plumbing for OPCM tooling). Batcher rotated (`0xE33D…D7d2` → `0xE840…1208`). PermissionedDisputeGame redeployed to rotate proposer (`0x30B6…2AC8` → `0xC7D3…0496`); other params unchanged ([diff](https://disco.l2beat.com/diff/eth:0xB4dAc1E9586f440430bc4F5d2ac4Ed2e51c24117/eth:0x63A70Bb5e1C613B5D2fCA1dac70C1408A271C0bE)).

### [2026-06-08 13:31 UTC](https://l2beat.com/layer2s/projects/funki?update=b47dbf73) (high severity, 5 changes)

PermissionedDisputeGame clone redeployed with new proposer + challenger immutable args ([diff](https://disco.l2beat.com/diff/eth:0x695F652b03470F396789cF007278F922e1726B94/eth:0xB4dAc1E9586f440430bc4F5d2ac4Ed2e51c24117)). SystemConfig `batcherHash` + `unsafeBlockSigner` rotated.

### [2026-05-15 13:08 UTC](https://l2beat.com/layer2s/projects/funki?update=bc137cee) (3 changes)

Scheduled signer-key rotation on shared OP Stack governance contracts (no threshold or permission changes):
- DeputyPauseModule (`0x76fC2F971FB355D0453cF9F64d3F9E4f640E1754`): `deputy` rotated from `0x352f1defB49718e7Ea411687E850aA8d6299F7aC` to `0x2fA150379bF32b6d79Eeb4ff9bD280E76049a87c`. Executed via [superchain-ops eth/052](https://github.com/ethereum-optimism/superchain-ops/pull/1399); the [DeputyPauseModule spec](https://specs.optimism.io/protocol/deputy-pause-module.html) specifies that this is a regular rotation.
- OpFoundationUpgradeSafe: Member rotated.

### [2026-05-05 15:18 UTC](https://l2beat.com/layer2s/projects/funki?update=6f0f1824) (1 change)

Optimism Security Council (`eth:0xc2819DC7...`) — member 12 swap: `0x92827223` → `0xcbC7dCeb`. Shared multisig (referenced by multiple Superchain projects).

### [2026-03-25 10:06 UTC](https://l2beat.com/layer2s/projects/funki?update=7713c532) (4 changes)

Three signers of the shared OpFoundation multisigs (OpFoundationUpgradeSafe) were rotated. The old signer at position 0 was a GnosisSafe (0x42d27eEA1AD6e22Af6284F609847CB3Cd56B9c64) which was replaced by a new EOA.

### [2026-02-27 13:19 UTC](https://l2beat.com/layer2s/projects/funki?update=450547af) (2 changes)

Optimism Security Council: 2 members replaced.

### [2026-01-24 16:32 UTC](https://l2beat.com/layer2s/projects/funki?update=381079e4) (2 changes)

SaferSafes module (LivenessModule + TimelockGuard) added to OpFoundationUpgradeSafe. Timelock delays currently 0.

### [2025-12-18 08:55 UTC](https://l2beat.com/layer2s/projects/funki?update=e39193c7) (high severity, 5 changes)

upgrade to safe 1.4.1

### [2025-11-28 09:51 UTC](https://l2beat.com/layer2s/projects/funki?update=88dd24a8) (high severity, 103 changes)

Jovian upgrade.

### [2025-07-14 12:45 UTC](https://l2beat.com/layer2s/projects/funki?update=61008130) (13 changes)

Discovery rerun on the same block number with only config-related changes.

### [2025-04-06 08:20 UTC](https://l2beat.com/layer2s/projects/funki?update=d09ecccd) (high severity, 67 changes)

Operators change, no change to implementations.

### [2025-04-04 10:09 UTC](https://l2beat.com/layer2s/projects/funki?update=644e95a8) (13 changes)

Standard Orbit chain.

## Operator

### The system has a centralized operator

The operator is the only entity that can propose blocks. 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 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.

**References**

- [Sequencing Window - OP Mainnet Specs](https://github.com/ethereum-optimism/optimism/blob/51eeb76efeb32b3df3e978f311188aa29f5e3e94/specs/glossary.md#sequencing-window)

## Withdrawals

### Regular exits

The user initiates the withdrawal by submitting a regular transaction on this chain. When a state root containing such transaction is settled, the funds become available for withdrawal on L1 after 3d 12h. Withdrawal inclusion can be proven before state root settlement, but a 7d period has to pass before it becomes actionable. The process of state root settlement takes a challenge period of at least 3d 12h to complete. Finally the user submits an L1 transaction to claim the funds. This transaction requires a merkle proof.

### 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, including forced withdrawals from L1 and regular messages initiated on L2. Once the force operation is submitted and if the request is serviced, the operation follows the flow of a regular message.

**References**

- [Forced withdrawal from an OP Stack blockchain](https://docs.optimism.io/stack/transactions/forced-transaction)

## Other considerations

### EVM compatible smart contracts are supported

OP stack chains are pursuing the EVM Equivalence model. No changes to smart contracts are required regardless of the language they are written in, i.e. anything deployed on L1 can be deployed on L2.
