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

Reentrancy in BMONSeedAndPreSale.buyTokens() (#283-312):
External calls:
- token.transfer(msg.sender,tokenAmount) (#296)
External calls sending eth:
- address(benificiary).transfer(msg.value) (#297)
State variables written after the call(s):
- totalPresaleTokensSold += tokenAmount (#302)
Apply the check-effects-interactions pattern.

BMONSeedAndPreSale.buyTokens() (#283-312) ignores return value by token.transfer(msg.sender,tokenAmount) (#296)
BMONSeedAndPreSale.buyTokens() (#283-312) ignores return value by token.transfer(msg.sender,tokenAmount) (#307)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.


Contract ownership is not renounced (belongs to a wallet)

Pragma version>=0.7.0<0.9.0 (#1) is too complex
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

BMONSeedAndPreSale.closePreSale() (#314-320) ignores return value by token.burn(token.balanceOf(address(this))) (#318)
Ensure that all the return values of the function calls are used.

BMON.allowance(address,address).owner (#119) shadows:
- Ownable.owner() (#28-30) (function)
BMON.transferFrom(address,address,uint256).owner (#123) shadows:

BMON.boosterBuyingAllowance(address).owner (#139) shadows:
- Ownable.owner() (#28-30) (function)
BMON.boosterBuyingAllowance(address,address).owner (#143) shadows:
- Ownable.owner() (#28-30) (function)
Rename the local variables that shadow another component.

BMON.setSeedAndPresale(address) (#153-155) should emit an event for:
- seedAndPresale = seedAndPresale_ (#154)
- seedAndPresale = seedAndPresale_ (#154)
Emit an event for critical parameter changes.

BMONSeedAndPreSale.setStartTime(uint256) (#251-253) should emit an event for:

BMON.setSeedAndPresale(address).seedAndPresale_ (#153) lacks a zero-check on :
- seedAndPresale = seedAndPresale_ (#154)
BMONSeedAndPreSale.constructor(address,address).beneficiary_ (#246) lacks a zero-check on :
- benificiary = beneficiary_ (#248)
Check that the address is not zero.

BMONSeedAndPreSale.getState() (#259-273) uses timestamp for comparisons
Dangerous comparisons:
- block.timestamp < startTime (#260)
- block.timestamp >= startTime && block.timestamp < startTime + SEED_DURATION (#261)
- block.timestamp >= startTime + SEED_DURATION && block.timestamp < startTime + SEED_DURATION + DELAY_BEFORE_PRESALE (#265)
- block.timestamp >= startTime + SEED_DURATION + DELAY_BEFORE_PRESALE && block.timestamp < startTime + SEED_DURATION + DELAY_BEFORE_PRESALE + PRESALE_DURATION (#266-267)
- block.timestamp >= startTime + SEED_DURATION + DELAY_BEFORE_PRESALE + PRESALE_DURATION (#271)
Avoid relying on block.timestamp.
