NanoShiba [Nano Shiba Inu] Token
About NanoShiba
Listings
Website
Nano Shiba Inu is a one-of-a-kind reward and rebase token that uses a proprietary contract on the Binance Smart Chain.
Holders of Nano Shiba Inu are rewarded in $SHIB token rewards that are distributed automatically through one of the contract’s protocols.
At the center of it all, the goal remains to create a project that gives a voice to its holders by creating an unbreakable community foundation.
Creating a community project is embracing and recognising that strength and growth does not come from a single perspective, but by creating a cohesive unit, where the sum of all parts come together to make it whole.
First and foremost we are supporters and enthusiasts of cryptocurrency and decentralised finance, and the technology behind it, and it's ability to revolutionise the world.
We embrace all with open arms, our community is 100% dedicated to respect, equality, and there is no room for discrimination.
We are a team that understands the value in community and collaboration. We come together to share our ideas and content with our community and the world of DeFi, and also
are a team that wants to help others, and keep the global adoption of DeFI as the overlaying goal for us all.
And finally, we care about taking initiative and speaking with our actions. We see the potential this project has and we will do everything we can to make our vision a reality.

NANOSHIBAINU.swapBack() (#728-776) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#759)
- (tmpSuccess,None) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#760)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DividendDistributor.distributeDividend(address) (#337-348) ignores return value by RWRD.transfer(shareholder,amount) (#343)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

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.
Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.
