Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

EMOCOINDividendTracker.getAccount(address) (EMOCOINDividendTracker.sol#373-420) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (EMOCOINDividendTracker.sol#417-419)
EMOCOINDividendTracker.canAutoClaim(uint256) (EMOCOINDividendTracker.sol#445-451) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (EMOCOINDividendTracker.sol#446)
- block.timestamp.sub(lastClaimTime) >= claimWait (EMOCOINDividendTracker.sol#450)
Avoid relying on block.timestamp.
