# Soon Alpha Mainnet Markdown version of https://ethbeat.org/layer2s/projects/soon ## Summary **Warning:** There are impactful changes and part of the information might be outdated. **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.

These typically occur every 44m 44s on average. ## Risk summary **Warning:** Fraud proof system is currently under development. Users need to trust the block proposer to submit correct L1 state roots. ### Funds can be stolen if 1. a contract receives a malicious code upgrade. There is no delay on code upgrades (CRITICAL), 2. an invalid state root is submitted to the system (CRITICAL). ### Funds can be lost if 3. the sequencer posts an unavailable transaction root (CRITICAL), 4. the data is not available on the external provider (CRITICAL). ### Funds can be frozen if 5. the centralized validator goes down. Users cannot produce blocks themselves and exiting the system requires new block production (CRITICAL). ### MEV can be extracted if 6. the operator exploits their centralized position and frontruns user transactions. ## Risk analysis **Warning:** Fraud proof system is currently under development. Users need to trust the block proposer to submit correct L1 state roots. ### 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 None (3d challenge period; sentiment: bad) Currently the system permits invalid state roots. More details in project overview. ### Data availability External (sentiment: bad) Proof construction and state derivation fully rely on data that is posted on EigenDA. The sequencer is publishing data to EigenDA v2. Sequencer transaction data roots are not checked against the DACert Verifier onchain. ### 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 Soon Alpha Mainnet is not even a Stage 0 project. **Warning:** There is no available node software that can reconstruct L2 state transitions from available DA, so this system cannot be independently verified. ### Stage 0 2 issues need fixing. - Met: The project self-identifies as a Validium or Optimium. - Met: State roots are posted to Ethereum L1. - Issue: The proof system is still under development. - Issue: No source-available node exists that can reconstruct the L2 state from the DA layer. ### Stage 1 3 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. [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 posted to EigenDA Transactions roots are posted onchain and the full data is posted on EigenDA. Since the ServiceManager bridge is not used, availability of the data is not verified against EigenDA operators, meaning that the Sequencer can single-handedly publish unavailable commitments. If EigenDA becomes unavailable, the sequencer falls back to Ethereum. **Risks** - Funds can be lost if the sequencer posts an unavailable transaction root (CRITICAL). - Funds can be lost if the data is not available on the external provider (CRITICAL). **References** - [EigenDA Docs - Overview](https://docs.eigenda.xyz/overview) - [Derivation: Batch submission - OP Mainnet specs](https://github.com/ethereum-optimism/specs/blob/main/specs/protocol/derivation.md#batch-submission) - [BatchInbox - address](https://etherscan.io/address/0xfF000000000000000000000000000000000000FF#code) - [OptimismPortal.sol - source code, depositTransaction function](https://etherscan.io/address/0x24331B68bea70c2b086BC883EEEA551BAF80C2BA#code) ## State validation ### No state validation OP Stack projects can use the OP fault proof system, already being deployed on some. This project though is not using fault proofs yet and is relying on the honesty of the permissioned Proposer and Challengers to ensure state correctness. The smart contract system permits invalid state roots. **Risks** - Funds can be stolen if an invalid state root is submitted to the system (CRITICAL). **References** - [L2OutputOracle.sol - source code, deleteL2Outputs function](https://etherscan.io/address/0x8b89b84B978f00e4Db5B70c3a0a567A74Cf7fDD4#code) ## Upgrades & Governance ### Past upgrades The metrics include upgrades on the currently used proxy contracts.

Only the permissioned proposer can submit state roots and rotate its own address. The SoonMultisig (challenger) can delete proposed outputs, change the 3-day finalization period and the submission interval, and rotate the challenger address. DisputeGameFactory, KailuaGame, KailuaTreasury, FaultDisputeGame, PermissionedDisputeGame and RiscZeroVerifier are no longer referenced. - OptimismPortal 3.11.0-beta.2 -> 2.8.1-beta.1 (SOON fork): https://disco.l2beat.com/diff/eth:0xcd87F6B5B03A73733ab5A9cbB56951600f3330A6/eth:0x24331B68bea70c2b086BC883EEEA551BAF80C2BA Batcher rotated. The last batch was posted to the batch inbox on 2026-07-11 and the new batcher has not posted since. ### [2026-07-14 15:59 UTC](https://ethbeat.org/layer2s/projects/soon?update=37598bb8) (high severity, 16 changes) SOON paused on 2026-07-12; reason unknown. Guardian EOA rotated (`0x7fFB…1593` → `0xcb17…B911`), the new guardian was also added to SoonMultisig (member[3]), then it called `pause` on the `SuperchainConfigFake` — OptimismPortal2, L1CrossDomainMessenger, L1StandardBridge, L1ERC721Bridge all read `paused: true` through it. OptimismPortal2 impl upgraded ([tx](https://etherscan.io/tx/0xa4ccaddf2ef0b79355fce160a4241d1b637cb32d6a1b6b7c12eea57f32577f0c)); `disputeGameFinalityDelaySeconds` and `proofMaturityDelaySeconds` extended 8h → 10d. SystemConfig `opStackDA.isUsingEigenDA` set to `false` (was `"v3"`) — EigenDA disabled. ### [2025-12-12 15:40 UTC](https://ethbeat.org/layer2s/projects/soon?update=54206c28) (high severity, 33 changes) OptimismPortal replaced with OptimismPortal2 using dispute games. Significant change compared to standard OptimismPortal2 is the possibility for a Guardian to freeze withdrawals with updateWithdrawalFrozenState(). ### [2025-07-14 12:46 UTC](https://ethbeat.org/layer2s/projects/soon?update=c385a2d0) (10 changes) Discovery rerun on the same block number with only config-related changes. ### [2025-05-30 05:44 UTC](https://ethbeat.org/layer2s/projects/soon?update=848fe65a) (2 changes) signer change. ### [2025-04-09 13:41 UTC](https://ethbeat.org/layer2s/projects/soon?update=7716d94f) (high severity, 46 changes) L2OutputOracle upgrade: Challenger can change the challenge period. ### [2025-03-07 14:39 UTC](https://ethbeat.org/layer2s/projects/soon?update=fb74e565) (high severity, 5 changes) `SequencerPubkeyInfos` struct added to the SystemConfig. This is not used by anything but assumed to store sequencer pubkeys for their EigenDA sequencer. ### [2025-02-26 16:48 UTC](https://ethbeat.org/layer2s/projects/soon?update=d691cd4c) (1 change) Withdrawal unfrozen and finalized: - prove (https://etherscan.io/tx/0x79eda9b1db8676c0bac77e96a1eb76b27e9c4bd557019b35632f70bd7b90f90c) - freeze (https://etherscan.io/tx/0x296cc7e2aa191bcf14b2c2f157f86e336448c696c07994b39671c89c396a9eb0) - unfreeze (https://etherscan.io/tx/0x7b49b8bd227cd19e5e5535ca8860d3c3ce5f7c1b202b19f463a2e64903810f7d) - finalize (https://etherscan.io/tx/0xf6ac1f315271e5db80c179889623c8fddef37c6cccc6dccdc2c1e9ea25a03347) config related: added categories for all opstack, op stack and polygoncdk stack templates. ### [2025-02-21 13:37 UTC](https://ethbeat.org/layer2s/projects/soon?update=9aaa5d93) (high severity, 38 changes) Minor upgrade to allow changing the proposer, challenger and guardian by the respective role itself. ### [2025-02-12 15:49 UTC](https://ethbeat.org/layer2s/projects/soon?update=5989acb0) (high severity, 18 changes) OptimismPortal upgrade: Add function to 'freeze' specific withdrawals, which prevents finalization and withdrawal. ### [2025-01-20 12:05 UTC](https://ethbeat.org/layer2s/projects/soon?update=6ad5c995) (high severity, 3 changes) Upgrade of the L1StandardBridge with a one-line change: ERC20SharedDecimals = 9 (was 12). ### [2025-01-16 13:34 UTC](https://ethbeat.org/layer2s/projects/soon?update=292455a4) (10 changes) Initial discovery. SOON is a fairly standard OP Stack (with no proofs) with SVM as the execution environment all EVM addresses are changed to SOL addresses (byte32) ERC20 token transfers are not allowed, only ETH they are using EigenDA for DA with no bridge (no trace of Service Manager) ## 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. **References** - [L2OutputOracle.sol - source code, CHALLENGER address](https://etherscan.io/address/0x8b89b84B978f00e4Db5B70c3a0a567A74Cf7fDD4#code) - [L2OutputOracle.sol - source code, PROPOSER address](https://etherscan.io/address/0x8b89b84B978f00e4Db5B70c3a0a567A74Cf7fDD4#code) ### 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) - [OptimismPortal.sol - source code, depositTransaction function](https://etherscan.io/address/0x24331B68bea70c2b086BC883EEEA551BAF80C2BA#code) ## 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. The process of block finalization takes a challenge period of 3d to complete. **Risks** - Funds can be frozen if the centralized validator goes down. Users cannot produce blocks themselves and exiting the system requires new block production (CRITICAL). **References** - [OptimismPortal.sol - source code, proveWithdrawalTransaction function](https://etherscan.io/address/0x24331B68bea70c2b086BC883EEEA551BAF80C2BA#code) - [OptimismPortal.sol - source code, finalizeWithdrawalTransaction function](https://etherscan.io/address/0x24331B68bea70c2b086BC883EEEA551BAF80C2BA#code) - [L2OutputOracle.sol - source code, PROPOSER check](https://etherscan.io/address/0x8b89b84B978f00e4Db5B70c3a0a567A74Cf7fDD4#code) ### 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 ### Solana Virtual Machine is supported OP stack chains are usually pursuing the EVM Equivalence model. But Soon implements the rust-based Solana virtual machine (SVM) which uses parallel processing. **References** - [Soon Docs - Decoupled SVM](https://docs.soo.network/introduction/decoupled-svm) ## Permissions Explore these contracts and permissions in Disco, ETHBEAT's contract explorer: https://disco.l2beat.com/ui/p/soon ### Ethereum #### Actors ##### SoonMultisig Addresses: [0xD686D498a67Bb96FAa4afA3b2b1Cf182f5c3A701](https://etherscan.io/address/0xD686D498a67Bb96FAa4afA3b2b1Cf182f5c3A701) A Multisig with 2/4 threshold. - Can upgrade **with no delay** - L2OutputOracle [via: ProxyAdmin] - SystemConfig [via: ProxyAdmin] - OptimismPortal [via: ProxyAdmin] - L1ERC721Bridge [via: ProxyAdmin] - L1CrossDomainMessenger [via: ProxyAdmin] - SuperchainConfig [via: ProxyAdmin] - L1StandardBridge [via: ProxyAdmin] - Can interact with L2OutputOracle - Allowed to challenge or delete state roots proposed by a Proposer - change the finalization period (challenge period) - Can interact with SystemConfig - it can update the preconfer address, the batch submitter (Sequencer) address and the gas configuration of the system - Can interact with AddressManager - set and change address mappings [via: ProxyAdmin] Participants (4): [0xd1bc675f91C9E54C8eA5Adc7B22Cae4C6AD39BB8](https://etherscan.io/address/0xd1bc675f91C9E54C8eA5Adc7B22Cae4C6AD39BB8), [0x7b12Dc6d2b7F13d1283E9CCe9eC818C09CB02432](https://etherscan.io/address/0x7b12Dc6d2b7F13d1283E9CCe9eC818C09CB02432), [0x6437a4b69e0CF59F21D2cdB59FFaB9dc115A0643](https://etherscan.io/address/0x6437a4b69e0CF59F21D2cdB59FFaB9dc115A0643), [0xcb17B5F3Cf75eb40F0Addf97B0D457922f10B911](https://ethbeat.org/layer2s/projects/soon#EOA-1) (EOA 1) ##### EOA 1 Addresses: [0xcb17B5F3Cf75eb40F0Addf97B0D457922f10B911](https://etherscan.io/address/0xcb17B5F3Cf75eb40F0Addf97B0D457922f10B911) Member of SoonMultisig. - Can interact with OptimismPortal - Allowed to pause withdrawals.
