META KITTIES An ERC20 meme token that fosters and promotes healthy and widespread usage and decentralization of the project through a specific reward linked to users transactions involving decentralized wallets. At the same time, 2% of the total amount is burned from each transaction, which makes the project deflationary.
Meta KittiesSwap Decentralized exchange that features custom functionality and allows holders to trade among themselves and without any centralized point of failure any meme token (Doge, SHIB, Floki, BabyDoge) for another.
Kitties Pools With the help of these pools, our users can hold META KITTIES and receive passive income for this in the form of other meme tokens.
NFT Marketplace, where users can buy unique NFTs and earn real money with them in our games. The better and more unique the NFT, the higher your monthly income.
Wallet tracker where users can track their prizes and rewards out of META KITTIES usage, current token valuations, wallet balance, and more. This wallet is built into all our Marketplaces and games.
A merchandise store run by a ownerless, stockholderless non-profit organization to allow META KITTIES holders to support meme tokens fun in the real world, with any and all proceeds supporting the META KITTIES project growth, maintenance and future features. The founders of the project already at the start agreed with 4,000 merchants from Estonia and Germany.
Dog Games. Play dog farm or dog city. Our games use NFTs and meme tokens that you can earn. Moreover, the project is developing a whole metaverse for meme tokens.
Launchpad. Our users will be able to purchase startup meme tokens at the best prices. Each startup passes our audit and META KITTIES guarantees its users safety.
Meta KittiesSwap
Meta KittiesSwap Decentralized exchange that features custom functionality and allows holders to trade among themselves and without any centralized point of failure any meme token (Doge, SHIB, Floki, BabyDoge) for another.
Meme tokens have become the most popular in the cryptocurrency market. We decided to create the first thematic decentralized exchange for millions of meme token holders, as well as games in which they can earn these tokens, as well as unique gaming NFTs.
Cryptocurrency should be anonymous and accessible to everyone. You can not restrict the exchange, transactions, trade to any users. In 2022, we have witnessed how exchanges block the accounts of their users for political reasons. This is unacceptable in our industry. This goes against the idea of Bitcoin founder Satoshi Nakamoto.
META KITTIES aims to solve these problems. We are building a decentralized trading platform, Meta KittiesSwap, where only users own their assets. We are also creating a decentralized Marketplace, which is not affected by sanctions and political conflicts between states. If a citizen of any country cannot buy any goods for dollars or euros, then he can easily do this with the help of META KITTIES tokens.
NFTs have become very popular. We create NFTs with real-life applications in our games and our marketplace. Our users will be able to receive income in games, discounts in the marketplace. Receiving income from these NFTs, the MetaKittiesproject will be able to buy tokens from the market and actively develop it.
Welcome to the World of Kitties, where you can play, trade, farm and get unique NFTs
META KITTIES was created in February 2022 with the goal of being a decentralized and deflationary meme project with true purpose.
Our mission is to bring popular cryptocurrency concepts to the mainstream. Unlike older, comparable projects, META KITTIES introduces holders to next-gen concepts such as participation rewards, NFTs, decentralized exchanges, and more.

/*
Asuna Inu is an anime ERC20 token with the name inspired by Asuna Yuuki, a character from the popular Japanese series “Sword Art Online”. Asuna is a kind and helpful young woman who, similarly to Kirito, cannot abandon another in trouble. She takes the game very seriously and is determined to clear it before Kirito tells her to enjoy SAO a bit. Asuna is also somewhat proud and despite her kind personality, she will not hesitate to get physical with those that challenge her authority or make fun of her abilities.
Asuna Inu token is a community-oriented project. The biggest selling point of Asuna Inu is that we offer passive rewards to our holders with a 2% tax redistribution for all transactions. Nonetheless, this token is designed with a deflationary function and it is achieved by our special burn function.

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// We derive the sqrtPriceX96 via Maker's own oracles to prevent price manipulation in the pool:
//
// p0 = price of token0 in USD
// p1 = price of token1 in USD
// UNITS_0 = decimals of token0
// UNITS_1 = decimals of token1
//
// token1/token0 = (p0 / 10^UNITS_0) / (p1 / 10^UNITS_1) [Conversion from Maker's price ratio into Uniswap's format]
// = (p0 * 10^UNITS_1) / (p1 * 10^UNITS_0)
//
// sqrtPriceX96 = sqrt(token1/token0) * 2^96 [From Uniswap's definition]
// = sqrt((p0 * 10^UNITS_1) / (p1 * 10^UNITS_0)) * 2^96
// = sqrt((p0 * 10^UNITS_1) / (p1 * 10^UNITS_0)) * 2^48 * 2^48
// = sqrt((p0 * 10^UNITS_1 * 2^96) / (p1 * 10^UNITS_0)) * 2^48
//
// Once we have the sqrtPriceX96 we can use that to compute the fair reserves for each token. This part may be slightly subjective
// depending on the implementation, but we expect most tokens to provide something like getUnderlyingBalancesAtPrice(uint160 sqrtPriceX96)
// which will forward our oracle-calculated `sqrtPriceX96` to the Uniswap-provided LiquidityAmounts.getAmountsForLiquidity(...)
// This function will return the fair reserves for each token. Vendor-specific logic is then used to tack any uninvested fees on top of those amounts.
//
// Once we have the fair reserves and the prices we can compute the token price by:
//
// Token Price = TVL / Token Supply
// = (r0 * p0 + r1 * p1) / totalSupply

Wojak Inu
Can INU change your life? Wojak has the answer.
Wojak Inu is the variation of the original meme Wojak. The original Wojak is usually used as the symbol of sadness, melancholy, regret and loneliness. However, the Wojak Inu depicts the most updated and totally new sides of the supposedly sad Wojak. It presents a new version of Wojak with a big smiley face after gaining the icon of cryptocurrency - the cute INU as his life companion.
What makes the pessimistic Wojak transformed into this optimistics Wojak? It is all because of the SHIBA INU he purchased back then! As many of you may have noticed, the lives of many people have changed because of SHIBA INU and Wojak is one of them.
If you wish to share the happiness of Wojak, join us!

With a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells
1. Buy limit and cooldown timer on buys to make sure no automated bots have a chance to snipe big portions of the pool.
2. No Team & Marketing wallet. 100% of the tokens will come on the market for trade.
3. No presale wallets that can dump on the community.
Token Information
1. 1,000,000,000,000 Total Supply
3. Dev team has provided liquidity
4. Fair launch for everyone!
5. 2% transaction limit on launch
6. Buy limit lifted 5 miinutes after launch
7. Sells limited to 10% of the Liquidity Pool
8. Sell cooldown increases on consecutive sells, 4 sells within a 24 hours period are allowed
9. 2% redistribution to holders on all buys
10. 7% redistribution to holders on the first sell, increases 2x, 3x, 4x on consecutive sells
11. Redistribution actually works!
12. 5-6% developer fee split within the team
