white paper

Shib Fén Inu has been created from the idea of establishing a positive friendship with the world wide community of Shiba Inu. The project is simple and clear and the mission of Shib Fén Inu is very simple…. We want to decimate the supply of Shiba Inu.
If you are a holder of Shiba Inu you will no doubt be driven and waiting for the burns to keep coming. We found many projects offer Shiba Inu as rewards, this is great as it helps the holder count but we struggle to see the overall benefit to Shiba Inu holders as we all know holders are not sending those free tokens to the dead wallet. So that lead the team to Shib Fén Inu.

The team want to keep Shib Fén Inu very clear and simple for investors and people looking at the project.
Shib Fén Inu is designed to be the friendly token that everyone should have alongside their Shiba Inu. There are over 1million holders of Shiba Inu across the globe who are dedicated and simply buying and holding Shib Fén Inu will mean big burns of ShibaInu.

Offering BNB rewards to holders means they will get value back directly in their wallet with the automatic rewards system. This allows people to easily fill up with more Shib Fén Inu or allow them to continuously receive back a % of their investment for doing nothing else other than holding Shib Fén Inu.

The BuyBack feature will be done manually by the team. The buy back will be used to predominantly buy Shiba Inu and then send it to the dead wallet removing from circulation forever. The value of this to holders of Shiba Inu means not only will Shib Fén Inu help to push the value of Shiba Inu but also burning the Shiba Inu purchased means that value put into Shiba Inu will remain.
The BuyBack wallet will also be used if needed to implement the same for Shib Fén Inu if the project needs the boost.

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.


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.
