/**
* @dev This contract implements a proxy that is upgradeable by an admin.
*
* To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector
* clashing], which can potentially be used in an attack, this contract uses the
* https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two
* things that go hand in hand:
*
* 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if
* that call matches one of the admin functions exposed by the proxy itself.
* 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the
* implementation. If the admin tries to call a function on the implementation it will fail with an error that says
* "admin cannot fallback to proxy target".
*
* These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing
* the admin, so it's best if it's a dedicated account that is not used for anything else. This will avoid headaches due
* to sudden errors when trying to call a function from the proxy implementation.
*
* Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract. If set up this way,
* you should think of the `ProxyAdmin` instance as the real administrative interface of your proxy.

🦦 The purpose of the project is for charity as we would like to help people and aqua life! Simply hold and receive passive income! This will be beneficial for the token holders.
🧑🌾 A farming/staking smart contract is currently in progress and awaiting audit!
💸 🚀 A fair, silent launch will be held with the intention of avoiding whales pumping and dumping the project.
🗝 We have locked liquidity for six months to show the community that we are dedicated to the project

Shiba Inu... everyone knows him. If it weren't for his silverspoon upbringing and toxic relationship with Elon Musk you would have never met him.
Now It's time to meet me: Scuba Inu! While you all have been shifting through the ocean of meme coins I've been here waiting patiently in its depths to be discovered.
Crypto voyagers prepare to be rich for you have just discovered a treasure!! Scuba Inu is here.
With a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, Myōbu was designed to reward holders and discourage dumping.
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. Developer provides LP
4. Fair launch for everyone!
5. 0,2% transaction limit on launch
6. Buy limit lifted after launch
7. Sells limited to 3% of the Liquidity Pool, <2.9% price impact
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

Myōba are celestial fox spirits with white fur and full, fluffy tails reminiscent of ripe grain. They are holy creatures, and bring happiness and blessings to those around them.
With a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, Myōba was designed to reward holders and discourage dumping.
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. Developer provides LP
4. Fair launch for everyone!
5. 5% transaction limit on launch
6. Buy limit lifted after launch
7. Sells limited to 3% of the Liquidity Pool, <2.9% price impact
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

Temple of Elon
The difference between gods and mortals is basically equal to the difference between the great Elon and man.
While the great gods of the pantheon were worshiped by priests at rituals in cultic centers,
the great god of the Tesla is worshiped by us on Twitter and cryptoworld.
Ancient mortals used to have no direct contact with their deities while contemporary people can easily receive oracles from the great Elon.
Ancient mortals worshiped personal gods, who were thought to be deities who could intercede on their behalf to ensure health and protection for their families;
while contemporary people worship Elon believing that he could protect us from scammers and earn profit in the crypto world.
All crypto buyers should devoutly praise the words of Elon. May the great Elon assuage the spirit of his followers and crypto holders.
May it soothe their hearts, bring wealth to his people.

Ethereum Qilin (ERC20 TOKEN)
Telegram: https://t.me/qilintoken
Website: https://qilintoken.io/
Twitter: https://twitter.com/Qilintoken
Total Supply -> 1,000,000
Redistribution -> 2%
LP Fee -> 12% (6% Developer, 6% sent back to liquidity pool)
Burn -> 0% (useless to burn tokens beforehand if they don't represent actual liquidity value)
(This means 50% of the LP fee will work in the holders advantage, sending money back into the liquidity pool)
Automated buy control (below for more information)
Basic MaxTX of 2%
Between 10th and 25th buy -> 3%
Between 25th and 50th buy -> 4%
Between 50th and 60th buy -> 5%
60th+ -> Unlimited

* -> What?
* [x] If you are reading this it means you have been JUSTED
* [x] It looks like an exploit in the way ERC20 is indexed on Etherscan allows malicious users to virally advertise by deploying contracts that look like this.
* [x] You pretty much own this token forever, with nothing you can do about it until we pull the UNJUST() function.
* [x] Just try to transfer it away, we dare you!
* [x] It's kinda like shitposting on the blockchain
* [x] Pls fix Papa Vitalik
* [x] Also we love your shirts.
*
*
* Also we're required to virally advertise.
* Sorry its a requirement
* You understand

What is JiX Swap?
JiXSwap is a decentralized exchange for swapping ERC-20 tokens.
Multi-chain support is planned for the next releases which is shown on the roadmap.
We built a platform for The crypto trading Industry
JiXSwap uses an automated market maker (AMM) model. That means that while you can trade digital assets on the platform, there isn’t an order book where you’re matched with someone else. Instead, you trade against a liquidity pool.
Those pools are filled with other users’ funds. They deposit them into the pool, receiving liquidity provider (or LP) tokens in return. They can use those tokens to reclaim their share, plus a portion of the trading fees.
JiXSwap Features
JiXSwap allows users to be Liqiudity Provider, Farming, Staking, Exchange, Bridging Assets across chains and more…
Liqiudity Provider
Pools are filled with other users’ funds. They deposit them into the pool, receiving liquidity provider (or LP) tokens in return. They can use those tokens to reclaim their share, plus a portion of the trading fees.
Farming
On the farm, you can deposit your LP tokens, locking them up in a process that rewards you with JIX. Which LP tokens can you deposit? Well, the list is quite long, but here’s a taster of some of the most popular ones.
Staking
JiXSwap allows you to stake its governance token. — JIX
You’ll earn a proportion of JIX token with every new BSC blocks.
Exchange
JiXSwap is an automated market maker (AMM) is a type of decentralized exchange (DEX) protocol that relies on a mathematical formula to price assets. Instead of using an order book like a traditional exchange, assets are priced according to a pricing algorithm.
Bridging Assets
Cross-chain bridging service that aims to increase interoperability between different blockchains. It essentially lets anyone convert selected coins into wrapped tokens (or “pegged tokens”) across chains. i.e. ERC20-BEP20
JiXSwap Roadmap
It’s a to-do list with particular timeline. We will work hard to release roadmap items before deadline.
JiX Swap Token (JIX)
JIX TOKEN
Contract Address:
Name: JiX Swap Token
Ticker: JIX
Decimals: 18
Max supply: 50,000
JIX Liquidity Mining and Burn Rates
Emission Rate: 0.75 JIX/block or 21600 JIX/day [may change in future]
Block Reward: Current block reward is 0.75 JIX. [may change in future]
• To preserve JIX Token value, we decided to burn 2000*(Block Reward) JIX Token every day.
• Nearly 9.09% of the total produced JIX will be sent to the deployer address for marketing&burning. The rest will be distributed among farms&pools on our platform.
• The team will not sell or farm any JIX token. The amount accumulates on the deployer address will be used only for marketing, contents&competitions and future airdrop. The only income for the developer team is deposit fees.
Importance of unique inflation control mechanism:
• Allocating this budget for marketing instead of buyback will help us grow & expand, hence, increasing coin value much more compared to buybacks.
• Income from deposit fees is negligible compared to the size of JIX/ETH and JIX/USDT pools. As a result of this, the value increase of JIX after the buyback will also negligible.
• Buyback can backfire since times of buybacks can create a pump/dump environment, and like said in the second argument, the value increase of the token is negligible due to the high volume of pools.
Deposit Fees
Standard deposit fee is 4% across all NON-JIX farms and pools. For JIX farms and pools, there is no deposit fee (0%). 50% of the deposit fee will be distributed among developers, the other 50% will be used for mainly marketing, buyback, and other expenses such as airdrops, contests, maintenance, etc.
JIX as a Governance Token
JIX is the native governance token of JiX Swap. We are advocates of decentralized platforms, because of this, we will lead our platform to success with our community. The community uses this platform and the community will lead this platform.
Our governance model is explained on Governance. As said there, after compulsory developments are being done, we will give control to our community.
Governance
Since our platform is decentralized, after the core development updates, we will give control to our community. Any JIX governance token holders may propose a change, update or development via our governance portal. Our governance structure will be like this:
First, any community member will propose their suggestion in our Discord channel’ #issues, then our community will talk upon this issue in Discord and Telegram. If this issue is agreed upon, the team will carry this proposal to the project page on Snapshot or Aragon.(the original issue can be amended before going to Snapshot page) When a proposal listed on Snapshot, those who hold JIX can vote either yes or no.
If the majority of JIX holders vote yes, then the team will execute the proposal.
If the majority of JIX holders vote no, then the team will not take action upon this proposal.
Any failed proposal can be talked upon in our socials, but they can be issued again after 2 weeks.

* @dev Implementation of the {IERC20} interface.
*
* This implementation is agnostic to the way tokens are created. This means

* For a generic mechanism see {ERC20PresetMinterPauser}.
*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

SEIZE the memes of production !!!!!
Have you ever wondered why a meme could become so powerful?
Do you think memes are all about a normal picture filled with funny content OR you already know memes could be a powerful cultural weapon that can have a significant impact on our daily lives?
Memes are carriers of cultural information.
The images at the beginning of this post are clear examples of memes in this sense, not because they made you laugh
(or, more than likely, cringe), but because they allowed for the transmission of culturally salient information.
One meme could become viral simply because it contains vast popular information.
We believe that the cryptoworld is the best place to indicate and show how powerful one meme is.
Shiba is one of the best and significant examples to show how powerful one meme can be,
various projects are named after Shiba and most of them turn out successful.
Combining the power of Shiba and the meme, we deliver MemeShiba to maximize the memes of production! Join us and SEIZE the memes of production !

*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.
