*
* 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 interface of your proxy.

* Support for ERC20 is included in this contract, as specified by the EIP: both
* the ERC777 and ERC20 interfaces can be safely used when interacting with it.
* Both `IERC777.Sent` and `IERC20.Transfer` events are emitted on token
* movements.
*
* Additionally, the `granularity` value is hard-coded to `1`, meaning that there
* are no special restrictions in the amount of tokens that created, moved, or
* destroyed. This makes integration with ERC20 applications seamless.
*
* AUGUR Modifications:
* - Public burning functions are note available. The ERC777 standard says they can be made to fail for some or all calls.
* - A hook is exposed for subclasses to send additional logs on transfer events
* - The ERC1820 Registry contract is not hardcoded but instead provided later on in the class heirarchy during runtime. This makes testing simpler.
* - To follow coding standards some member variables with underscores were renamed in favor of simply exposing those variables to satisfy ERC20 and ERC777 interface requirements
* - The internal _mint function allows a boolean to specify requireReceptionAck. Our variable supply tokens will not require this.
* - The internal _burn function allows a boolean to specify wether 1820 hooks are called. Our variable supply tokens will not call them. Calling them would put our contracts at risk for malicious hooks

Welcome to $OLYMPUS
This is a community token. So there is no official group.
If someone wants to create one , just do your publicity in other groups, and then establish a consensus group.
There is only one channel recording the information when I released this coin.
If you want to view all the information about this coin, please check https://t.me/OlympusOfficial_Channel
I'll lock liquidity LPs through team.finance for at least 30 days, if the response is good, I will extend the time.
I'll renounce the ownership to burn addresses to transfer $OLYMPUS to the community, make sure it's 100% safe.
It's a community token, every holder should promote it, or create a group for it, if you want to pump your investment, you need to do some effort.
Great features:
1.Fair Launch!
2.No Dev Tokens No mint code No Backdoor
3.Anti-sniper & Anti-bot scripting
4.Anti-whale Max buy/sell limit
5.LP send to team.finance for 30days, if the response is good, I will continue to extend it
6.Contract renounced on Launch!
7.1000 Billion Supply and 50% to burn address!
8.Auto-farming to All Holders!
9.Tax: 8% => Burn: 4% | LP: 4%
4% fee for liquidity will go to an address that the contract creates,
and the contract will sell it and add to liquidity automatically,
it's the best part of the $OLYMPUS idea, increasing the liquidity pool automatically.
I’m gonna put all my coins with 9ETH in the pool.
Can you make this token 100X or even 10000X?
Hope you guys have real diamond hand

* 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.

The gas lane to use, which specifies the maximum gas price to bump to. For a list of available gas lanes on each network, see https:docs.chain.link/docs/vrf-contracts/#configurations Depends on the number of requested values that you want sent to the fulfillRandomWords() function. Storing each word costs about 20,000 gas, so 100,000 is a safe default for this example contract given that we will request 2 words. Test and adjusr this limit based on the network that you select, the size of the request, and the processing of the callback request in the fulfillRandomWords() function. The number of block confirmations before returning the request. The default is 3, but you can set this higher. For this example, retrieve 2 random values in one request.

/**
* @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.

*

* @dev Implementation of the {IERC20} interface.

* 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}.
