Hello, i'm actually learning solidity.
I have found this contract : https://snowtrace.io/address/0x3a3d8628D095A897DaADDfe37F882871cE6D3036#code

Creator said :
AntiDump :
-Buy : 10% = 4% to all holder, 3% to marketing, 3% to liquidity
-Sell : 18% = 8% to all holder, 5% to marketing, 5% to liquidity

But i can't find it on code, it's possible to do that ?

Thanks you in advance.
