*
* 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}.

* Using this library instead of the unchecked operations eliminates an entire
* class of bugs, so it's recommended to use it always.

/**
* @dev Wrappers over Solidity's arithmetic operations with added overflow
* checks.
*
* Arithmetic operations in Solidity wrap on overflow. This can easily result
* 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.

ℍ𝕪𝕡𝕖𝕣𝕔𝕪𝕔𝕝𝕖 is brought to you by seasoned developers from past hypercycles. The team has extensive background in developing successful meme coins.
They've been able to create over 10+ Meme coins with over 3M daily volume EACH. They've also cracked the code of achieving top 3 trending on Dextools. (this can't always be achieved since it includes multiple external factors.)
To prove that we are not only talk, we've decided to launch this coin with one of our old wallets. This wallet created ''SpaceShiba'' which managed
to perform fantastically. It raked in over 3m+ Daily volume with a total of 1500+ transactions. It can still be found in over 500 peoples wallets. (All of this can be viewed on Dextools.)
To commemorate past HODLers we've decided to airdrop the top 100 holders of ''SpaceShiba'' a total of 1% of $HYPEs total supply (0.01% EACH).
The name ℍ𝕪𝕡𝕖𝕣𝕔𝕪𝕔𝕝𝕖 reffers to the good old days, when the uniswap volume was unmatched. We've been keeping an eye on the sidelines and have noticed that the volume now is slowly starting to match the one we all miss.
Tokenomics:
- Total Supply: 1,000,000,000 $HYPE
- Launch Liquidity: 3 Ethereum
- Burned Supply: 20% before launch
- Airdrop: 1% to the top 100 ''SpaceShiba'' HODLers. (These addresses can be double checked from the multisender TX)
- Tax: 10% ( 4% on Buys & 4% on Sells)
- Token Redistribution: 2% ( 1% on Buys & 1% on Sells)
- Some buy backs will be performed by the fee wallets and the bought tokens burned.
- Launch buy limit: 1% of the total supply.
- LIQUIDITY WILL BE LOCKED BEFORE TRADING HAS BEEN ENABLED!

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

It’s time to apply all that we have learned
Tokens bought and tokens spurned
Private keys and several seeds
With which we’ve written all our deeds
But still fall silent our hopes still pending
For a transaction not unwished sending
At last on this nonce arose a degen anthem for us to sing
“We’re all going to make it” let the blockchain ring
- 100% Tokens to Liquidity / No premine dev token wallet
- Dev tax 7% at time of launch
- Launch with 2% Wallet Cap Limit

*
* 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.

$BARK Token
$BARK is the parent token of the whole ecosystem. Investors who hold $BARK will receive a 2% reflection on every transaction. Fees from the BARK MINER will be used to buy-back and burn $BARK tokens periodically.
Tokenomics:
1,000,000 Total Supply
10% Private Sale
1% Max Wallet
12% Buy/Sell Tax
BARK MINER
BARK Miner is a fork of the popular BSC project, Baked Beans. BARK Finance is a locked reward pool that gives rewards forever (Up to 12% daily).
TREASURY
A portion of fees from $BARK tokens will be accumulated into the treasury. The treasury will be used to contribute further funds into the TVL + also buyback and burn $BARK.
