* @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 `ERC20Mintable`.
* 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`.

SODIUM ($Na) is the essential element for living. SODIUM will become the key element for crypto investors.
Core Businesses of SODIUM:
SODIUM gateway
This gateway allows you to top up your Fiat or Crypto assets and pay to the merchants. Also, we support merchants to receive Crypto and we provide solutions to change the Crypto to Fiat for the merchants.
SODIUM exchange
We aim to provide a cross-chain DEX for all crypto users. We will launch an ERC-20 Exchange first and then extend the service to other chains. Our target is helping people to buy any crypto project from any chains.
Staking Reward
6% of each transactions and the all profit from SODIUM gateway & SODIUM exchange
will go for the reward pool to reward all the users who stack SODIUM in the pool.

A casino is a place that some people find similar to a hotel, where you can enjoy various types staying up all night but enjoying gambling activities at the same time.
However, Casino is actually a Colosseum. It is a place for gladiators to fight, to seize, to conqueror.
You either double your bet or you earn nothing if you are not a fighter material.
Living in a cryptocurrency world is exactly like gambling in a Casino; you need to play to earn your profit.
Shibagen is designed to tell those jeets. You either die like a gladiators or live long to see yourself becomes a stupid loser. Be bold, not jeets !

/*
The APE’s Dream is an otherworldly replica of the original Caesar's Workshop, now called the Abandoned Caesar Workshop under the Caesar's Ape Colony.
Created by Caesar and Malcolm, the Caesar's Dream was originally intended as a way to ensure there were always hunters to fight humans.
Caesar eventually realized that the Dream was bound to his consciousness, with each requiring the existence of the other,
and nearly went mad from the revelation of never dying yet serving an eternal cause.
The APE's Dream acts as a central hub and sanctuary for Ape warriors, where resources can be exchanged and weapons can be fortified here,
as well as a connection to every other location in Caesar's kingdom.
Gibber is now trapped inside the APE’s Dream and he decided to turn this endless loop of dream into a endless profit generating machine by establishing a treasury fund.
A REWARDING mechanism can be easily achieved due to our unique treasury fund. 11% tax will be charged in each transaction and automatically added into the treasury fund.
This treasury fund will be used to reward token holders each month and the rewarding method will be decided by our DREAM DAO.

/**
A PennyAuction-like game to win a prize.
UI: https://www.pennyether.com
How it works:
- An initial prize is held in the Contract
- Anyone may overthrow the Monarch by paying a small fee.
- They become the Monarch
- The "reign" timer is reset to N.
- The prize may be increased or decreased
- If nobody overthrows the new Monarch in N blocks, the Monarch wins.
For fairness, an "overthrow" is refunded if:
- The incorrect amount is sent.
- The game is already over.
- The overthrower is already the Monarch.
- Another overthrow occurred in the same block
- Note: Here, default gas is used for refund. On failure, fee is kept.
Other notes:
- .sendFees(): Sends accrued fees to "collector", at any time.
- .sendPrize(): If game is ended, sends prize to the Monarch.

// ethbox is a smart contract based escrow service. Instead of sending funds from A to B,
// users send funds through ethbox. This enables users to abort outgoing transactions
// in case of a wrong recipient address.
//
// Funds are put in "boxes". Each box contains all the relevant data for that transaction.
// Boxes can be secured with a passphrase. Users can request ETH or tokens in return
// for their deposit (= OTC trade).
//
// The passphrase gets hashed twice. This is because the smart contract needs to do
// its own hashing so that it cannot be manipulated - But the passphrase shouldn't
// be submitted in clear-text all over the web, so it gets hashed, and the hash of
// that is stored on the smart contract, so it can recognize when it is given the
// correct passphrase.
//
// Depositing funds into contract = createBox(...)
// Retrieving funds from contract = clearBox(...)
