white paper

NFT-Starter (NST) was originated as a pioneer created in more favorable, more consistent, more healthy development environment for the association between the new DeFi and NFT ecosystem. Our long-term vision for NFT-Starter is developing an NFT ecosystem based on Binance Smart Chain because we can slash gas fees to a minimum with more scalability and reliability. The plan to execute this vision starts with creating a prestigious, real-time, high-throughput experience in conjunction with launchpad governed by community. NFT-Starter platform positions itself with a highly digitalized, secure and accessible system, which supports the evolution of NFTs’ projects on the path to success. NFT-Starter ecosystem could create favorable conditions for the community to participate in NFT marketplace to raise capitals for NFT projects and value NFT assets in a more transparent and more complete manner. Members holding at least 2,000,000 NST Tokens can participate in the future IDOs and insurance pool. The role of NFT-Starter is as a provider of technology to have platform exclusively governed by NFT-Starter community. There are multiple benefits for NST holders such as earning BNB passively , IDO participation, voting power, farming (liquidity pool), earning rating star and many benefits coming in the future.

NST.addLiquidity(uint256,uint256) (#1158-1171) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,lockedLiquidity(),block.timestamp) (#1163-1170)
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.

NST.addLiquidity(uint256,uint256) (#1158-1171) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,lockedLiquidity(),block.timestamp) (#1163-1170)
Ensure that all the return values of the function calls are used.

NST._approve(address,address,uint256).owner (#1037) shadows:
- Ownable.owner() (#436-438) (function)
Rename the local variables that shadow another component.

Ownable.setLockedLiquidityAddress(address).liquidityAddress (#487) lacks a zero-check on :
- _lockedLiquidity = liquidityAddress (#490)
Check that the address is not zero.

SafeMath.mod(uint256,uint256,string) (#248-251) is never used and should be removed
Remove unused functions.

Additional information: link

NST._previousLiquidityFee (#737) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#380-401):
- (success,returndata) = target.call{value: weiValue}(data) (#384)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable NST._maxTxAmount (#747) is not in mixedCase
Follow the Solidity naming convention.

Variable NST._transferBothExcluded(address,address,uint256).rTransferAmount (#917) is too similar to NST._getValues(uint256).tTransferAmount (#949)
Prevent variables from having similar names.

NST.slitherConstructorVariables() (#709-1247) uses literals with too many digits:
- _tTotal = 100000 * 10 ** 6 * 10 ** 9 (#724)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

Ownable._burnAddress (#419) should be constant
Add the constant attributes to state variables that never change.

setRouter(address) should be declared external:
- NST.setRouter(address) (#1243-1245)
Use the external attribute for functions never called from the contract.
