Website
On the search for somewhere to place your investment? SPC has constructed a coin perfectly equipped to launch your portfolio into the cosmos. A Binance Smart Chain-powered token with a real use case. Anyone else like Galaga as much as we do? We are already in the late stages of the game's development and will have a video showcasing the game completed prior to DXsale launch.
We have a working play to earn function on your website now! https://play.spaceport.to/ As mentioned in our play to earn series, we've been rewarding our players a % of their current token holdings in correlation to the jackpot.
Rewards have been working and we're constantly updating our game to include multiple content updates such as Boss fights, new Npcs, and various different power upgrades. NFT art is included also in our rewards and in future development, we'll integrate those NFTs into the game.

SpacePort.addLiquidity(uint256,uint256) (#707-720) sends eth to arbitrary user
Dangerous calls:
- _uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#712-719)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.
SpacePort.reflectionFromToken(uint256,bool).tMarketing_scope_2 (#526) 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.
Additional information: link
SpacePort.addLiquidity(uint256,uint256) (#707-720) ignores return value by _uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#712-719)
Ensure that all the return values of the function calls are used.
Additional information: link
SpacePort._approve(address,address,uint256).owner (#472) shadows:
- Ownable.owner() (#102-104) (function)
Rename the local variables that shadow another component.
Additional information: link
SpacePort.setMinLiquidityPercent(uint256) (#587-591) should emit an event for:
- _numTokensSellToAddToLiquidity = _tTotal.mul(minLiquidityPercent).div(100) (#589-590)
Emit an event for critical parameter changes.

SpacePort.setUniswapPair(address).p (#613) lacks a zero-check on :
- _uniswapV2Pair = p (#614)
Check that the address is not zero.

Variable 'SpacePort.reflectionFromToken(uint256,bool).tMarketing (#517)' in SpacePort.reflectionFromToken(uint256,bool) (#512-534) potentially used before declaration: (tFee,tLiquidity,tMarketing) = _getTValues(tAmount) (#526-527)
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.

Ownable.unlock() (#133-138) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is still locked) (#135)
Avoid relying on block.timestamp.

SafeMath.mod(uint256,uint256,string) (#79-83) is never used and should be removed
Remove unused functions.
Additional information: link
SpacePort._previousMarketingFee (#391) is set pre-construction with a non-constant function or state variable:
- _marketingFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.4 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.

Variable SpacePort._uniswapV2Pair (#400) is not in mixedCase
Follow the Solidity naming convention.
Additional information: link
Redundant expression "this (#11)" inContext (#5-15)
Remove redundant statements if they congest code but offer no value.
Additional information: link
Variable SpacePort._getRValues(uint256,uint256,uint256,uint256,uint256).rTransferAmount (#853) is too similar to SpacePort._transferToExcluded(address,address,uint256).tTransferAmount (#784)
Prevent variables from having similar names.
Additional information: link
SpacePort.slitherConstructorVariables() (#362-885) uses literals with too many digits:
- _numTokensSellToAddToLiquidity = 500000000000 * 10 ** 9 (#394)
Use: Ether suffix, Time suffix, or The scientific notation
Additional information: link
SpacePort._tTotal (#377) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
isExcludedFromReward(address) should be declared external:
- SpacePort.isExcludedFromReward(address) (#599-601)
Use the external attribute for functions never called from the contract.
