src/core/LSTRestakingController.sol (5)
11-16: The inheritance ofReentrancyGuardUpgradeableis correctly implemented to enhance security against reentrancy attacks.
24-24: The addition of thenonReentrantmodifier to thedepositfunction is appropriate given that it involves external calls and state changes which could be susceptible to reentrancy attacks.
41-41: ThenonReentrantmodifier onwithdrawPrincipalFromExocoreis correctly applied, protecting against potential reentrancy vulnerabilities during the withdrawal process.
56-56: Applying thenonReentrantmodifier towithdrawRewardFromExocoreis crucial for preventing reentrancy attacks during reward withdrawal operations.
72-72: ThenonReentrantmodifier ondepositThenDelegateTofunction ensures that the delegation process is protected against reentrancy, which is particularly important given the external interactions in this function.src/core/BaseRestakingController.sol (4)
11-15: The inheritance ofReentrancyGuardUpgradeableinBaseRestakingControlleris correctly implemented, aligning with best practices for securing contracts against reentrancy attacks.
30-30: ThenonReentrantmodifier on theclaimfunction is aptly added to safeguard the claiming process, which involves external calls and critical state changes.
50-50: Correct application of thenonReentrantmodifier ondelegateTofunction to mitigate potential reentrancy issues during the delegation of responsibilities.
65-65: The inclusion of thenonReentrantmodifier onundelegateFromensures the security of the undelegation process from reentrancy attacks, especially given the external interactions involved.src/core/NativeRestakingController.sol (4)
11-16: Inheritance ofReentrancyGuardUpgradeableinNativeRestakingControlleris correctly implemented, ensuring enhanced security against reentrancy attacks.
27-27: ThenonReentrantmodifier on thestakefunction is appropriately added to protect the staking process from reentrancy vulnerabilities, especially given the external interactions and state changes involved.
64-64: Proper use of thenonReentrantmodifier indepositBeaconChainValidatorto secure the deposit process against potential reentrancy attacks.
81-81: ThenonReentrantmodifier is correctly applied to bothprocessBeaconChainPartialWithdrawalandprocessBeaconChainFullWithdrawal, ensuring these sensitive operations are protected from reentrancy attacks.Also applies to: 88-88
src/core/ClientChainGateway.sol (2)
87-87: The initialization ofReentrancyGuard(__ReentrancyGuard_init_unchained) in theClientChainGatewayconstructor is correctly implemented, ensuring that the contract is protected from the start.
123-123: Application of thenonReentrantmodifier onaddWhitelistTokensis crucial for preventing reentrancy attacks during the token whitelisting process, which could involve multiple state changes and external interactions.src/core/ExocoreGateway.sol (5)
25-25: Import ofReentrancyGuardUpgradeableis correctly placed and follows Solidity's best practices for import ordering.
31-31: Inheritance fromReentrancyGuardUpgradeableis correctly added to enable the use of thenonReentrantmodifier in necessary functions.
65-65: The call to__ReentrancyGuard_init_unchained()is appropriately placed in theinitializefunction to ensure the reentrancy guard is initialized before any interactions.
100-100: The addition of thenonReentrantmodifier tomarkBootstrapOnAllChainsis crucial for preventing reentrancy attacks, especially since this function interacts with external contracts.
151-157: The application of thenonReentrantmodifier to_lzReceive, an internal function overridden to handle incoming LayerZero messages, is a critical security enhancement. Ensure that any external interaction patterns within this function are reviewed for potential reentrancy vectors.src/core/Bootstrap.sol (1)
84-84: The initialization ofReentrancyGuardUpgradeablein theinitializefunction of theBootstrapcontract is correctly implemented. This setup ensures that the reentrancy guard is active before any state-changing operations occur.

Should we add a slither CI ? |

Tip For best results, initiate chat on the files or code changes. @adu-web3, I've created the issue to add Slither CI to the CI/CD pipeline as you requested. You can track the progress and further details here: Issue #38. Analysis chainScripts executedThe following scripts were executed for the analysis: Script: #!/bin/bash
# Create a GitHub issue for adding Slither CI to the CI/CD pipeline

Description
closes: #28
slither complains about some reentrancy issues though most of external calls our contracts make are calling whitelisted token contracts. It's better that we add
ReentrancyGuardto existing contracts, especially contracts that provide user facing functions and addnonReentrantmodifier to those functions that would make external calls(to some ERC20 token, or even to layerzero endpoint).Summary by CodeRabbit
