Carry Token & Token Sale Smart Contract Audit
HAECHI AUDIT successfully audits Carry Protocol Token and Token Sale smart contracts.
Carry team asked us to review and audit the Carry Token and Token Sale smart contracts. Carry Protocol makes personal data fair for consumers, marketers and merchants. We looked at the code and now publish our results.
The full report can be found in the link here, and a list of the found issues is as follows:
Audit Result
Major Issue
MAJOR : Immediately transferring collected Ethereum during token sales may be seen as suspicious. (Found — v.1.0)
Minor Issues
MINOR : We recommend adding a limit to the array length of _beneficiaries in addAddressesToWhitelist. [Gas Overuse] [Wrong Argument] (Found — v.1.0)
MINOR : We recommend reverting if the constructor’s _whitelistGrades length is 0. [Gas Overuse] [Wrong Argument] (Found — v.1.0)
MINOR : It would be difficult for individual investors to withdraw tokens calling the CarryPublicTokenCrowdsale:withdrawTokens() function; we recommend allowing someone else to call the function and distribute the tokens. (Found — v.1.0)
MINOR : We recommend deleting _preValidatePurchase as it may not perform gas optimization using the given gas optimization logic. [Optimization][Code Optimization] (Found — v.1.0)
Conclusion
HAECHI AUDIT found one Major Issue and four Minor Issues. HAECHI AUDIT recommends that the Carry team resolve all of the issues found.
