* 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:
* ```
* contract ERC1967 {
* bytes32 internal constant _IMPLEMENTATION_SLOT = 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc;
*
* function _getImplementation() internal view returns (address) {
* return StorageSlot.getAddressSlot(_IMPLEMENTATION_SLOT).value;
* }
*
* function _setImplementation(address newImplementation) internal {
* require(Address.isContract(newImplementation), "ERC1967: new implementation is not a contract");
* StorageSlot.getAddressSlot(_IMPLEMENTATION_SLOT).value = newImplementation;
* }
* }
* ```
*
* _Available since v4.1 for `address`, `bool`, `bytes32`, and `uint256`._

* @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
* behind a proxy. Since a proxied contract can't have a constructor, it's common to move constructor logic to an
* external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
* function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
*
* TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
* possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
*
* CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
* that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.

📝"Shikage will introduce an anti-rug LP locker with 2 modes:
Simple Lock - Shikage's simple LP lock will have a "cool-down" period during which the LP will be frozen and released after a period of time upon verification
SAFU Lock - Shikage's SAFU lock adds a KYC to the simple lock. In case of a scam, the KYC document will be shared with the community"

/*
Geass is a supernatural ability which certain people can bestow upon others. This power is usually called the Power of Kings. According to an English edition of "Newtype", the power of Geass has something to do with the very existence of humankind, and it may be used to destroy, control, or transform just about anything.
The power of Geass increases with use, and should the user lack the willpower, they may be consumed by it.
Lelouch states that the Geass is a form of wish. However, people who have Geass are not immune to the Geass effects of others. The Geass is represented by a glowing, bird-shaped symbol.

* TIP: For a detailed writeup see our guide

*
* 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}.

*
* 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
* allowances. See {IERC20-approve}.

EINSTEIN INU - $EINSTEIN
Einstein Inu is a connection between crypto and science , we are exposing scientific causes to a world of untapped capital.
In our view, there are fundamentally two different types of token: the ones that
deal with fiat currency; and the ones that deal purely in crypto. It is the latter one that we will focus on. Even though they are small now, we strongly believe that pure
Einstein Inu will build a world-class crypto token, powering the future of crypto finance.
TOKEN FEATURES :
- Investment launchpad
- Deflationary Tokenomics
- University Funding ( Building of scientific Lab and Artificial intelligence system)
- NFT Market Place
▫️6% Buy tax
▫️10% Sell tax
▫️100,000,000,000 Total supply
▫️Max tx 1,500,000,000
▫️Max wallet 3,000,000,000
Callers lined up - prelaunch and right after launch.
Launch date - Saturday 04/02 🚀
