/**

$OAT is a token created for those who have suffered too much loss in the crypto space. The rugpulls
and honepots can be very annoying and we have all been there. $OAT aims to help the best it can. To make generational
wealth, just HODL anon. The only mechanism for now, is to buy back and burn from the tax which wil increase the value of the token.
100% community token and 100% supply to Baseswap and Uniswap V2 later on. Final tax 2/2. 

We are launching on base first then on ethereum mainnet later on so we could take advantage of the volume for more
buy back and burn, especially on the base network. This will make history!!! 

Please note: We are making no promises but together, we can achieve greatness!

Below are our contacts for now, please do not get scammed!

$OAT - THE GOAL IS $1 AND BEYOND!
