About

Honeypot is an application-specific rollup designed to challenge the security of Cartesi Rollups. It provides a gamified battlefield to incentivize bug hunters to hack the application to obtain the funds locked in the rollup contract.

    Risk summary

    Funds can be frozen if

    1. the centralized validator goes down. Users cannot produce blocks themselves and exiting the system requires new block production (CRITICAL).

    MEV can be extracted if

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

    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 is no delay on this operation.

    State validation

    None

    Currently the system permits invalid state roots. More details in project overview.

    Data availability

    Onchain

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

    Exit window

    ∞

    Users can exit funds at any time because contracts are not upgradeable.

    Proposer failure

    Cannot withdraw

    Only the whitelisted proposers can publish state roots on L1, so in the event of failure the withdrawals are frozen.

    Learn more about Rollup stages
    Please keep in mind that these stages do not reflect rollup security, this is an opinionated assessment of rollup 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.
    Technology

    Fraud proofs are in development

    Ultimately, Cartesi DApps will use interactive fraud proofs to enforce state correctness. This feature is currently in development and the Honeypot DApp permits invalid state roots. Since Honeypot is immutable, this feature will not be added to the DApp.

    • Funds can be stolen if an invalid state root is submitted to the system by the configured Authority (CRITICAL).

    1. Authority.sol#L148 - Etherscan source code, submitClaim function

    All transaction data is recorded on chain

    All executed transactions are submitted to an on chain smart contract. The execution of the rollup is based entirely on the submitted transactions, so anyone monitoring the contract can know the correct state of the rollup chain.

    1. InputBox.sol#30 - Etherscan source code, addInput function
    State derivation
    Node software

    The Cartesi node software source code can be found here.

    Compression scheme

    No compression is used.

    Genesis state

    The genesis state is derived from the Honeypot Cartesi Machine template, which can be found within the Honeypot server Docker image at /var/opt/cartesi/machine-snapshots/0_0. Alternatively, it is possible to recreate it by following the build procedure outlined in the Honeypot GitHub Repository.

    Data format

    The reference implementation for ERC20 deposits can be found here. To learn about the withdrawal request format, please refer to the documentation here.

    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.

    Withdrawals

    Regular exit

    The user initiates the withdrawal by submitting a regular transaction on this chain. When the block containing that transaction is finalized the funds become available for withdrawal on L1. The process of block finalization usually takes several days to complete. Finally the user submits an L1 transaction to claim the funds. This transaction requires a merkle proof.

    • Funds can be frozen if the centralized validator goes down. Users cannot produce blocks themselves and exiting the system requires new block production (CRITICAL).

    Permissions

    The system uses the following set of permissioned addresses:

    Authority owner 0x79Ec…3861

    The Authority owner can submit claims to the Honeypot DApp.

    Smart contracts

    The system consists of the following smart contracts on the host chain (Ethereum):

    Honeypot 0x0974…C366

    CartesiDApp instance for the Honeypot DApp, responsible for holding assets and allowing the DApp to interact with other smart contracts. This contract can store any token.

    InputBox 0x59b2…c768

    Contract that receives arbitrary blobs as inputs to Cartesi DApps.

    ERC20Portal 0x9C21…a1DB

    Contract that allows anyone to perform transfers of ERC-20 tokens to Cartesi DApps.

    Authority 0x9DB1…C45f

    Simple consensus model controlled by a single address, the owner.

    History 0x3854…FAd9

    Contract that stores claims for Cartesi DApps.

    Value Locked is calculated based on these smart contracts and tokens:

    Generic escrow 0x0974…C366

    Contract storing bounty funds.
