    Users can be censored if

    1. the bridge operators decide not to mint tokens after observing a deposit.
    Technology

    Principle of Operation

    Eclipse implements a custom permissioned bridge. Withdrawals need to be actively authorized by a Multisig.

    1. CanonicalBridge.sol - Etherscan source code, authorizeWithdraw() function
    2. Mailbox.sol - Etherscan source code, receiveMessage() function calls CanonicalBridge

    Third party validation

    Deposits are processed by the bridge operators on the Eclipse side. There is no mechanism to send messages back to Ethereum.

    • Users can be censored if the bridge operators decide not to mint tokens after observing a deposit.

    • Funds can be stolen if the Treasury owner decides to transfer the funds locked on L1.

    1. Treasury.sol - Etherscan source code, emergencyWithdraw() function
    Permissions

    The system uses the following set of permissioned addresses:

    AuthorityMultisig 0x4720…64E0

    This is a Gnosis Safe with 3 / 5 threshold. Can pause and upgrade the EtherBridge and Mailbox contracts and change all parameters in the ‘CanonicalBridge’ contract or authorize/cancel withdrawals.

    AuthorityMultisig participants (5) 0xBb53…D5470xCD2f…e6A40x9508…B2a50x7572…BFc20xF48C…46FA

    Those are the participants of the AuthorityMultisig.

    TreasuryOwner 0x7B2c…0efC

    This is a Gnosis Safe with 3 / 5 threshold. Can upgrade and transfer funds from the Treasury.

    TreasuryOwner participants (5) 0xd061…cDb50x0706…8Fed0xDecF…96860xEe05…82D90x3392…C080

    Those are the participants of the TreasuryOwner.

    WithdrawerEOA 0x1a84…C4fE

    Can authorize arbitrary withdrawals from the Treasury (via the ‘CanonicalBridge’ contract) with a 7d delay.

    PauserEOA 0x6810…77D3

    Can pause standard withdrawals from the ‘CanonicalBridge’ contract and cancel withdrawals during the standard 7d delay.

    Smart contracts

    A diagram of the smart contract architecture

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

    CanonicalBridge 0x2B08…be11

    Entry point to deposit ETH. It is registered as a module in the Mailbox contract.

    Mailbox 0xb23B…968dImplementation (Upgradable)Admin

    Contract receiving messages from registered modules to send to Eclipse. It doesn’t have any functionality to send messages back to Ethereum.

    Treasury 0xD7E4…E644Implementation (Upgradable)Admin

    Holds the funds locked on Ethereum. This contract stores the following tokens: ETH.

    The current deployment carries some associated risks:

    • Funds can be stolen if a contract receives a malicious code upgrade. There is no delay on code upgrades (CRITICAL).
