* 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}

* 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
* 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 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}.

//! whereby the same hash must be provided by some number (specified in
//! constructor) of the set of owners (specified in the constructor, modifiable)

/*
Overflow safety:
We do not use SafeMath and control overflows by
not accepting large ints on input.
Balances inside contract are stored as int192.
Allowed input amounts are int112 or uint112: it is enough for all
practically used tokens: for instance if decimal unit is 1e18, int112
allow to encode up to 2.5e15 decimal units.
That way adding/subtracting any amount from balances won't overflow, since
minimum number of operations to reach max int is practically infinite: ~1e24.
Allowed prices are uint64. Note, that price is represented as
price per 1e8 tokens. That means that amount*price always fit uint256,
while amount*price/1e8 not only fit int192, but also can be added, subtracted
without overflow checks: number of malicion operations to overflow ~1e13.

* 1) operator's own permission set read from userRoles[operator]
* 2) target permission set - what is already set on the target

*
* @dev Corner cases:
* 1) Operator is super admin and its permission set is `FULL_PRIVILEGES_MASK`:
* `desired` bitset is returned regardless of the `target` permission set value
* (what operator sets is what they get)
* 2) Operator with no permissions (zero bitset):
* `target` bitset is returned regardless of the `desired` value
* (operator has no authority and cannot modify anything)
*
* @dev Example:
* Consider an operator with the permissions bitmask 00001111
* is about to modify the target permission set 01010101
* Operator wants to set that permission set to 00110011
* Based on their role, an operator has the permissions
* to update only lowest 4 bits on the target, meaning that
* high 4 bits of the target set in this example is left
* unchanged and low 4 bits get changed as desired: 01010011
*

* @title Illuvium (ILV) ERC20 token
*
* @notice Illuvium is a core ERC20 token powering the game.
* It serves as an in-game currency, is tradable on exchanges,
* it powers up the governance protocol (Illuvium DAO) and participates in Yield Farming.
*
* @dev Token Summary:
* - Symbol: ILV
* - Name: Illuvium
* - Decimals: 18
* - Initial token supply: 7,000,000 ILV
* - Maximum final token supply: 10,000,000 ILV
* - Up to 3,000,000 ILV may get minted in 3 years period via yield farming
* - Mintable: total supply may increase
* - Burnable: total supply may decrease
*
* @dev Token balances and total supply are effectively 192 bits long, meaning that maximum
* possible total supply smart contract is able to track is 2^192 (close to 10^40 tokens)
*
* @dev Smart contract doesn't use safe math. All arithmetic operations are overflow/underflow safe.
* Additionally, Solidity 0.8.1 enforces overflow/underflow safety.
*
* @dev ERC20: reviewed according to https://eips.ethereum.org/EIPS/eip-20
*
* @dev ERC20: contract has passed OpenZeppelin ERC20 tests,
* see https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/test/token/ERC20/ERC20.behavior.js
* see https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/test/token/ERC20/ERC20.test.js
* see adopted copies of these tests in the `test` folder
*
* @dev ERC223/ERC777: not supported;
* send tokens via `safeTransferFrom` and implement `ERC20Receiver.onERC20Received` on the receiver instead
*
* @dev Multiple Withdrawal Attack on ERC20 Tokens (ISBN:978-1-7281-3027-9) - resolved
* Related events and functions are marked with "ISBN:978-1-7281-3027-9" tag:

* @dev Implementation of the {IERC20} interface.

*
* 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}.

// The following contract automatically distributes the Eth raised from the
// token sale.
// 1. 40% of the Eth raised will go into a "development" ethereum wallet, immediately
// accessible to the team, to be used for marketing, promotion, development,
// running costs, exchange listing fees, bug bounties and other aspects of
// running the company.
//
// 2. 30% of the Eth will go into a "Tote Liquidator" ethereum wallet, which will be
// used by the team purely to to liquidate the ethertote over the the opening
// 12 weeks. It will be very easy to see the transactions on Etherscan as
// they will match the CryptoPot smart contracts that make up the Ethertote
// ecosystem.
//
// 3. 30% of the Eth will go into a time-locked smart contract called "Team Eth"
// which will be available to claim by the Ethertote team over a 12-month period
//
//
// Note that ALL Eth raised from the token sale will initially go to this
// smart contract

* An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
