/**
* @dev Wrappers over Solidity's arithmetic operations with added overflow
* checks.

* in bugs, because programmers usually assume that an overflow raises an
* error, which is the standard behavior in high level programming languages.
* `SafeMath` restores this intuition by reverting the transaction when an
* operation overflows.
*
* Using this library instead of the unchecked operations eliminates an entire
* class of bugs, so it's recommended to use it always.

From the makers of $DONSHIBA, we present to you... Bonsai Inu!
Bonsai Inu was raised in the Aokigahara jungle.
The fresh air coming from Mount Hotaka breezes through the jungle flora, and made sure all those who were raised here would be stronger then any of it's species.
Bonsai Inu dropped his past, since his superior bloodline was always involved in conflicts between different Inu tribes.
His interests for taking care of Bonsai trees increased over the year.
Holding Bonsai Inu will be rewarding because of the reflection & redistribution tokenomics.
As always, the developer will fund the starting liquidity, and after a burn there will be no wallets with any sort of tokens.
Fairest launch possible! Fake presale wallets and owner wallets are something Bonsai Inu doesn't want to see!
What Bonsai Inu offers you:
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. After a 15% burn, 85% of the tokens will come on the market for trade.
3. No presale wallets that can dump on the community. This is in my eyes, illegal!
4. A fast growing community that has a passion for ERC20 meme tokens!
5. Very nicely, from scratch made Bonsai Inu art, so those who take a glimps at him, will never forget it.
Token Information
1. 100,000,000,000 Total Supply
2. 15% Burned
3. Developer provides LP
4. Buy limit/cool down
5. Fair launch for everyone!
6. 5% redistribution to holders
7. 10% developer fee split within the team

Good luck on launch!

Recently news sources have been reporting on the negative affect that cryptocurrency can have on the environment from mining due to high electricity costs.
That's why ClimApe is stepping up to show them that we apes do care about our jungle.
ClimApe is here to fight climate change, by donating 8% of all buys and sells to OneEarth, a philanthropic organization working to accelerate collective action to limit global average temperature rise to 1.5°C.

/**
Eldring's rules
▶ If you make the biggest buy (in tokens) you will hold the Eldring for one hour, and collect 4% fees (in ETH) the same way marketing does.
Once the hour is finished, the counter will be reset and everyone will be able to compete again for the Eldring.
▶ If you sell any tokens at all at any point you are not worthy of the Eldring.
▶ If someone beats your record, they steal you the Eldring.

/**
* Implements battles between Loot weapon holders.
*
* The battle is a simple tug-of-war in which people can enlist to support
* either side. Each weapon contributes a "power" score that amplifies the
* strength of their side. At the end of the battle, the side with more power wins.
*
* A given warrior (address) can only participate in any individual battle once.
* In practice, some people might run multiple warriors via separate addresses,
* but our setup discourages this practice.
* Similarly, each weapon can only be used once in a given battle.
*
* We record the power of the weapon _at the time it is used_; upgrades to the
* weapon will have no effect on battles that weapon is currently in.
*
* Once a warrior and weapon are committed, there is no turning back, retreating,
* or switching sides. This simplifies the state tracking.
*
* Weapon power computation is abstracted behind an IPowerCalculator, which
* allows the possibility of re-balancing the game without needing to change
* this contract.
* Similarly, the distribution of battle rewards (XP) is handled through an
* IBattleRewarder, so we can tweak the XP reward mechanics without redeploying
* this contract.
*
* There is support for a v2 loot weapon contract; once we deploy it we can
* add the new contract address. Since all weapon stat calculation is abstracted
* behind the IPowerCalculator, from the perspective of this contract we only
* know that the loot weapons are ERC-721s and we check that warriors actually
* own them.

/**
* @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 inerface of your proxy.

ALL TIME HIGH TOKEN
Welcome to the All Time High Token. A simple concept token on both Eth (Uniswap) and BSC (Pancakeswap), introducing a game theory component, brought to you by that weird guy that runs LiqLockBot.
5% Tax on all buys and sells
- 2% Dev
- 3% to the ATH Wallet IN ETH/BSC!
To become the the ATH Wallet, simply be the person that buys at the top! If you bought the token for the highest price, you get 3% of all subsequent trades!
But, like anything in life, there is a catch. If you are the ATH Wallet holder, and you:
- Sell ANY of your tokens
- Transfer ANY of your tokens
you will forfeit your ATH Wallet holder rights. The next person that BUYS after you sell or transfer, automatically becomes the new ATH Holder (Until someone pays more than them)
Launch Details and Tokenomics
* Launching on both ETH and BSC
* 5% Tax on all Buys and Sells, converted to Ethereum.
* 5 minute buy to sell cool down (You can't sell if you bought within 5 minutes)
* 3 minute buy to buy cool down
* Launch Max TX Size of 0.5% of Total Supply (5000 tokens), will be raised after 1 hour
* 100% of supply to liquidity.
* Liquidity locked.
* No pre-sale
* Ownership renounced

/**
🌏 Cop26 Token 🌏
Because of the us, the earth is going to die and we are extinct our species.
The world leaders gathered in the #COP26 but they will not save us, they are just gathered and spend two weeks celebrating everything as usual and blah blah blah.
We need to change the world with our hands. This is the meme-token community for saving the world.
Do everything that you can do and we will donate the fee to the climate related charity. Let's save the world!

LemonApeStand ($LAS)
We decided to make a generous 3% dev tax token that goes to whales who can hold their ground.
This is a community token. Community vs Whales. With community joint efforts whales can be beat!
We all make riches. Don't jeet.

/**
PANDAO seeks to reduce the control centralized organizations have over information, and instead put personal data into the hands of the people.
We also aim to produce tools for DAOs, allowing more individuals to work full-time for this new type of organization. PANDAO is more than just a decentralized media organization.
We are developing new decentralized data systems and liberating internet products and human resources from Web2.
PANDAO has been community-managed since the beginning, and now continues this path by decentralizing all authority over the treasury.
Token holders own 100% of the treasury assets. This white paper was created with the purpose of establishing ground rules which will discipline evildoers and motivate the contributors in the DAO.
Elections will occur in cycles, keeping the power of project initiators or evildoers in check.
The white paper also defines the proposal process, review steps, and voting weights, which enable management and workers to hear the voice of everyone in the community.

What Is Laminar (Laminar)?
Laminar is an open financial platform founded in 2019 that powers margin and synthetic assets trading. The platform is based on Ethereum and uses DeFi building blocks and Flow Protocols to meet the community's needs.
In 2021, the Laminar developer team started to launch Flowchain using Substrate to scale to a high-performance retail chain. As a partner in the Polkadot ecosystem, Flowchain will contribute to this interoperable and scalable blockchain ecosystem. The Substrate-based Laminar Chain connects Polkadot as a parachain in order to strengthen the overall security of Polkadot and the DeFi community.
In the early stages of its launch, Laminar received funding from the Web 3.0 Foundation, an organization that also sponsored Polkadot and Kusama.
Who Are the Founders of Laminar?
Laminar was founded by the team behind the Acala Network and Karura (KAR). It consists of Ruitao Su, Bette Chen, and Bryan Chen.
Ruitao Su is currently co-founder of Acala and CEO of Laminar. He is a former CTO of Centrality, an award-winning software engineer, talented entrepreneur, investor, and advisor to technology companies and startups.
Bette Chen is a co-founder at Acala Network and COO at Laminar Protocol since 2019. She is a visionary product manager and skilled entrepreneur. Chen received academic degrees in Engineering (Software) and Business (MBA). She has impressive experience in management and leadership in the high-tech industry.
Bryan Chen is another co-founder of the Acala Network. He is also the co-founder and CTO of Laminar. Chen is an irreplaceable contributor to the Substrate codebase and a Polkadot Ambassador.
Antonia Chen is Chief Economist at Laminar. Chen holds a Ph.D. in economics and is experienced in tech startups, microeconomics, mathematics research, and token economy design.
Ermal Kaleci holds the position of Senior Software Engineer at the company. Kaleci is a well-known KYC and mobile wallet App developer and an award-winning mobile developer as well.
What Makes Laminar (Laminar) Unique?
Laminar is a decentralized financial protocol that creates an open and reliable trading platform for crypto traders and traditional financial market traders alike. The main goal of the project: to offer modern and competitive business models to financial service providers and strengthen the DeFi ecosystem in general. Here are the main points of development:
Synthetic Asset: Users can trade various financial assets and earn interest on their holdings. The effectiveness lies in the fact that traders block 100% of the value of an open position, and liquidity providers cover the risks.
Margin Trading: There is an option to open short and long positions with leverage. The advantages are instant liquidity and limited risks for traders, and the protocol fixes the potential profit.
Money Market: An integrated option where the user can earn interest in the trading process. The interest rate is floating; it provides a profitability and liquidity guarantee.
It’s worth paying attention to the fact that Laminar offers decentralized margin trading. The platform opens up opportunities for conducting leveraged trading transactions on a decentralized basis and using synthetic digital assets.
The Flow Protocols offer the following features:
Instant Liquidity: Users trade against smart contracts, which means there is instant and endless liquidity. This happens if the collateral ratio doesn’t fall below the specified liquidation threshold.
Asset Efficiency: Traders need to provide collateral in the amount of the value of the positions. The rest of the risks are taken by the liquidity providers who receive the transaction fees. In fact, even margin traders can trade against liquidity pools.
Environment for Trading Experience: Protocols provide transparent pricing and proper counterparty actions that are governed by both the protocol and the community.
Integrated Money Market: Financial assets deposited by traders and liquidity providers generate interest, which increases liquidity.
Laminar Flow Protocols strive to be blockchain-independent. The platform enables both synthetic and margin trading, which helps to combat opaque pricing and price manipulation in financial markets.

How Many Laminar (Laminar) Coins Are There in Circulation?
As of June 2021, Laminar ERC-20 tokens are not in circulation. Relevant information about the business plan of the cryptocurrency (tokenomics) is also not available. The confirmed specifics on the Initial Token Sale (ICO) weren’t published on the official channels of the project, so the exact details (total supply of Laminar tokens and their distribution) are currently unknown.
How Is the Laminar Network Secured?
Laminar supports the Ethereum smart contract implementation, which acts as a value gateway to fully utilize the DeFi Ethereum ecosystem, providing liquidity and trading diversity. On top of that, for maximum protection, the network uses a PoS (proof-of-stake) mechanism, the significant advantages of which include security, reduced risk of centralization, and energy efficiency.

* We have followed general OpenZeppelin Contracts guidelines: functions revert

* 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
