$LOCKER
Launches on March 28th (ERC)
Goal
Instead of individual Teams developing their own Apps,
$LOCKER packages it all into a single App and makes it available for Teams, players, and Fans.
Money Transfers, Marketplace Sales, Contract Agreements, Milestone based payouts, etc.
Hyped launch with presale/private. Solid team. vested for 1-3 years
LP Lock 6 Months, CERTIK AUDIT in the works, various marketing plans in the works - Not personally worked with this team but have seen the team members around in other based chats.

Viking Inu Shiba (VIKING SHIBA🍺)
Telegram: https://t.me/VikingShiba
Autism got you down? Can't relate to people in the real world?
Fear no more! Viking Shiba has got your back! This token embodies
not only the dream that Elon has for a new financial system, but
also his social deficiencies as well!
Features include:
- 5% Reflection to autistic holders
- Anti-listing-bot, only autists can buy
- No team tokens, devs are autistic
- Anti whale dumping protection
- Cooldown and tax on mass sells
- Burn 20% of the initial token supply
- Full liquidity provided and locked

*
* 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}.

Call weaponComponents(), chestComponents(), etc. to get
an array of attributes that correspond to the item.
The return format is:

[1] = Suffix ID (0 for none)
[2] = Name Prefix ID (0 for none)
[3] = Name Suffix ID (0 for none)

$APEER is the king of the future apes. $APEER is a community based token to grow the future ape kingdom with the token holders.
Kingdom is built and based by the community. All of the token holders have obligations to shill and market the project to grow our kingdom of ape.
Crown and power is for all the active holders. If you hold $APEER and shill elsewhere, you will have a chance to get a certain amount of the tax.
$APEER will use the scepter to burn the token to make the $APEER become one of the most popular deflationary tokens in ERC.
Throne is for the king. It is used by the development team to do marketing and develop further utility in the next stage.

/**
* @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}.

🐅 Welcome to Kotatsu Nyan - the comfiest Cat Token based off Ethereum! 🐱
WHY KOTATSU?
⇸ We are a token that revolves around it's community. Developers have locked liquidity and renounced ownership to ensure safety!
⇸ We plan on donating regularly to animal shelters from a wallet that takes 1% of transaction fees. 2% is reflected to all holders!
⇸ NFT trading cards backed by KOTATSU tokens are in the works.
⇸ A BSC based version of this token and a bridge is in progress - after two weeks, a snapshot will be taken at a random time and people will be airdropped 50% of their holdings in the ERC20 token!

"Wit beyond measure is man's greatest treasure."
— Rowena Ravenclaw
As far as we are concerned, the admission to Hogwarts is selective. However Hogwarts is now providing us the second opportunity for you to become an official wizard in the cryptoword. Embrace yourself, here comes the sorting hat!
There's nothing hidden in your head
The Sorting Hat can't see,
So try me on and I will tell you
Where you ought to be.
Or yet in wise old Ravenclaw,
if you've a ready mind,
Where those of wit and learning,
Will always find their kind;
Members of the Ravenclaw were characterised by their wit, learning, and wisdom. This is the house designed for wizards and witches that possess extraordinary wisdom. Ravenclaw corresponded roughly to the element of air, and it was for that reason that the House colors were chosen; blue and bronze represented the sky and eagle feathers respectively.
Welcome RAVENCLAW ! To be officially part of us you will need to purchase the community token as part of the admission fee. You will be able to redeem your own wands and your enchanting pets !

/**
* @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.
