Fair Auto Donate Ukraine: $FADU
-5% of Each Sell Automatically Goes to Ukraine

Tokenomics:
10% of each buy goes to existing holders via Reflections.
5% of each sell goes directly to Ukraine (0x165CD37b4C644C2921454429E7F9358d18A45e14)
5% of each sell will be used to buy back $FADU

Website:
https://etherscan.io/address/0x165CD37b4C644C2921454429E7F9358d18A45e14

Why Fair？

Marketingwalletaddress is Gnosis Safe wallet,0x9F7459D992633f212b9EA99368b8B022F328906A

https://gnosis-safe.io/app/eth:0x9F7459D992633f212b9EA99368b8B022F328906A/balances

Every 12 hours will buyback $FADU and what time to buyback decided by the maxbuywallet(not sell)

We will add the maxbuywallet to Gnosis Safe wallet

As you konw,some guys said "will be used to buy back $MCC for the #MultiNodes rewards pool" It is a trick!

SAFU:

Lock 100% LP for month(Will Extend if need)

RenounceOwnership

All Announcement will on twitter:https://twitter.com/FADU_tokens
