DIAMONDHANDS [DIAMOND HANDS] Token

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

DIAMONDHANDS.swapAndLiquify(uint256) (#2098-2117) sends eth to arbitrary user
Dangerous calls:
- marketingWallet.transfer(marketingAmount) (#2109)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Reentrancy in DividendPayingToken._withdrawDividendOfUser(address) (#1412-1428):
External calls:
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (#1417)
State variables written after the call(s):
- withdrawnDividends[user] = withdrawnDividends[user].sub(_withdrawableDividend) (#1420)
Apply the check-effects-interactions pattern.

SafeToken.withdraw(address,uint256) (#1734-1737) ignores return value by IERC20(_token).transfer(safeManager,_amount) (#1736)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

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.

DIAMONDHANDS._transfer(address,address,uint256).extraFee (#2067) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

DIAMONDHANDS._transfer(address,address,uint256) (#2033-2096) ignores return value by dividendTracker.process(gas) (#2089-2094)
Ensure that all the return values of the function calls are used.

DividendPayingToken.constructor(string,string)._symbol (#1369) shadows:
- ERC20._symbol (#832) (state variable)
Rename the local variables that shadow another component.

DIAMONDHANDS.setSwapAtAmount(uint256) (#2161-2163) should emit an event for:
- swapTokensAtAmount = _swapAtAmount (#2162)
Emit an event for critical parameter changes.

Additional information: link

DIAMONDHANDS.setMarketingWallet(address)._marketingWallet (#2165) lacks a zero-check on :
- marketingWallet = _marketingWallet (#2166)
Check that the address is not zero.

Variable 'DIAMONDHANDS._transfer(address,address,uint256).iterations (#2089)' in DIAMONDHANDS._transfer(address,address,uint256) (#2033-2096) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#2090)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

Reentrancy in DIAMONDHANDSDividendTracker.processAccount(address,bool) (#1710-1720):
External calls:
- amount = _withdrawDividendOfUser(account) (#1711)
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (#1417)
State variables written after the call(s):
- lastClaimTimes[account] = block.timestamp (#1714)

DIAMONDHANDSDividendTracker.canAutoClaim(uint256) (#1638-1644) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1639)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1643)
Avoid relying on block.timestamp.

Low level call in DIAMONDHANDS.swapAndLiquify(uint256) (#2098-2117):
- (success) = address(dividendTracker).call{value: dividends}() (#2112)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
