    Risk summary

    Funds can be stolen if

    1. a contract receives a malicious code upgrade. Both regular and emergency upgrades must be approved by both the Security Council and the Foundation. There is no delay on regular upgrades.

    MEV can be extracted if

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

    Sequencer failureState validationData availabilityExit windowProposer failure
    Sequencer failure
    Self sequence

    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)

    Fraud proofs allow actors watching the chain to prove that the state is incorrect. Interactive proofs (INT) require multiple transactions over time to resolve.

    Data availability
    Onchain

    All of the data needed for proof construction is published on Ethereum L1.

    Exit window
    None

    There is no exit window for users to exit in case of unwanted upgrades as they are initiated by the Security Council with instant upgrade power and without proper notice.

    Proposer failure
    Self propose

    Anyone can be a Proposer and propose new roots to the L1 bridge.

    The project passes the walkaway test: users can exit in the presence of malicious operators even if the Security Council disappears.
    Learn more about 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

    All data required for proofs is published on chain

    All the data that is used to construct the system state is published on chain in the form of cheap blobs or calldata. This ensures that it will be available for enough time.

    State derivation
    Node software

    The rollup node is composed of two software components: op-node, implementing consensus related logic, and op-geth, implementing execution logic. The configuration file can be found here.

    Compression scheme

    Data batches are compressed using the zlib algorithm with best compression level.

    Genesis state

    The genesis file can be found here.

    Data format

    The format specification of Sequencer’s data batches can be found here.

    State validation

    A diagram of the state validation

    Updates to the system state can be proposed and challenged by anyone who has sufficient funds. 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 0.08 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.

    1. OP stack specification: Fault Dispute Game
    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 691.43 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. 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), if a clock gets inherited with less than 3h, it generally gets extended by 3h with the exception of 6h right before depth 30, and 1d right before the last depth. The maximum clock extension that a top level claim can get is therefore 10d. 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).

    Karst hardfork (Upgrade 19b, op-contracts/v7.0.0) L2 activation on 2026-07-08 16:00:01 UTC. Most predeploys now inherit ProxyAdminOwnedBase , which lets a contract read its proxy's ProxyAdmin and ProxyAdmin owner on-chain so privileged functions can be gated to them. On the initializable ones — both bridges, both mintable factories, L2CrossDomainMessenger and every FeeVault — the constructor calls disableInitializers() and initialize() is restricted to the ProxyAdmin or its owner (the SuperchainProxyAdminOwner). L1Block is not initializable but inherits the same base and gates its new setFeature setter the same way. Custom gas token support was removed from L2StandardBridge and L2CrossDomainMessenger. The gasPayingToken() override is gone, and withdraw() / withdrawTo() no longer revert on custom gas token chains. Ink pays gas in ETH, so behaviour is unchanged. L2ProxyAdmin (1.0.0) adds upgradePredeploys(address) , which delegatecalls the L2ContractsManager. FeeVault configuration (recipient, minimum withdrawal amount, withdrawal network) moved from constructor immutables to storage set by initialize() , and is now mutable post-deployment via setRecipient , setMinWithdrawalAmount and setWithdrawalNetwork — each gated to the ProxyAdmin owner. Previously these values were fixed at deployment; the SuperchainProxyAdminOwner can now change them.

    Karst hardfork (Upgrade 19b, op-contracts/v7.0.0) L2 activation on 2026-07-08 16:00:01 UTC.

    Most predeploys now inherit ProxyAdminOwnedBase, which lets a contract read its proxy’s ProxyAdmin and ProxyAdmin owner on-chain so privileged functions can be gated to them. On the initializable ones — both bridges, both mintable factories, L2CrossDomainMessenger and every FeeVault — the constructor calls _disableInitializers() and initialize() is restricted to the ProxyAdmin or its owner (the SuperchainProxyAdminOwner). L1Block is not initializable but inherits the same base and gates its new setFeature setter the same way.

    Custom gas token support was removed from L2StandardBridge and L2CrossDomainMessenger. The gasPayingToken() override is gone, and withdraw() / withdrawTo() no longer revert on custom gas token chains. Ink pays gas in ETH, so behaviour is unchanged.

    L2ProxyAdmin (1.0.0) adds upgradePredeploys(address), which delegatecalls the L2ContractsManager.

    FeeVault configuration (recipient, minimum withdrawal amount, withdrawal network) moved from constructor immutables to storage set by initialize(), and is now mutable post-deployment via setRecipient, setMinWithdrawalAmount and setWithdrawalNetwork — each gated to the ProxyAdmin owner. Previously these values were fixed at deployment; the SuperchainProxyAdminOwner can now change them. BaseFeeVault and L1FeeVault are byte-identical and now share implementation 0xf7bed7215EEF1003fac426682Cf2edeb958569f7.

    GasPriceOracle stayed at 1.6.0 with unchanged source; only its implementation address moved.

    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.

    • 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.

    1. Sequencing Window - OP Mainnet Specs
    2. OptimismPortal2.sol - source code, depositTransaction function
    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.

    1. OptimismPortal2.sol - Etherscan source code, proveWithdrawalTransaction function
    2. OptimismPortal2.sol - Etherscan source code, finalizeWithdrawalTransaction function

    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.

    1. Forced withdrawal from an OP Stack blockchain
    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.
