Constantly fluctuating supply through decentralized burning and the development of a staking and non-fungible token (ERC721) mining system using Arteon Graphics Cards to generate passive income.

Token seems to be (relatively) fine. It still become a scam, but probability is moderate.



Token (#336-706) contract sets array length with a user-controlled value:
- lockReason[_to].push(_reason) (#596)
Token (#336-706) contract sets array length with a user-controlled value:
- lockReason[msg.sender].push(_reason) (#575)
Do not allow array lengths to be set directly set; instead, opt to add values as needed. Otherwise, thoroughly review the contract to ensure a user-controlled variable cannot reach an array length assignment.

Token.unlock(address) (#672-690) ignores return value by this.transfer(_of,unlockableTokens) (#689)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract locking ether found:
Contract Token (#336-706) has payable functions:
- Token.fallback() (#702-704)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Owned.transferOwnership(address)._newOwner (#80) lacks a zero-check on :
- newOwner = _newOwner (#84)
Check that the address is not zero.

Token.tokensUnlockable(address,bytes32) (#663-670) uses timestamp for comparisons
Dangerous comparisons:
- locked[_of][_reason].validity <= now && ! locked[_of][_reason].claimed (#668)
Avoid relying on block.timestamp.

Token.approveAndCall(address,uint256,bytes) (#492-505) compares to a boolean constant:
-require(bool)(ApproveAndCallFallBack(_spender).receiveApproval(msg.sender,_value,this,_data) == true) (#501)
Remove the equality to the boolean constant.

SafeMath.div(uint256,uint256) (#163-171) is never used and should be removed
SafeMath.mul(uint256,uint256) (#153-161) is never used and should be removed
Remove unused functions.

Pragma version^0.4.24 (#5) allows old versions
solc-0.4.26 is not recommended for deployment
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.
