// This contract is part of Zellic’s smart contract dataset, which is a collection of publicly available contract code gathered as of March 2023. //SPDX-License-Identifier: Cucklicensed /* Hi fellow etherscan vagrant, idk whats up with the state of defi right now but * Yesterday I deployed YURU, idk what happened with that. No promotion, no sharing, no announcement, just liquidity, I held initially 99.99% of the supply, people bought * I just did it for fun for no reason: * MEVs fucked everyone, generated $1.8m in volume * EDIT: You guys have 100% slippage MEV bots took 99% of real user buys on YURU. * Anyways I sold some of my tokens to make back liquidity, deploy txn costs, and some profit * Why? I believe I'm not obliged to maintain such a random, ERC20 deployed for no reason. I didn't tell anyone to buy, nor forced anyone to buy. * also congrats whoever is looking at this you are a true degenerate wtf :) * Fucking around on mainnet is so interesting */ pragma solidity ^0.8.0;
