The Honest Token is the Funds-Distribution Honest Labs' native token.

It is a ERC-20 token with the implementation of the ERC-2222 Fund Distribution Standar.

This means that any funds in ETHER that is sent to this contract (The token contract) will be 
proportionally distributed among token holders, even if token holders sell their tokens before 
having withdrawn their dividends.

This allows token holders to earn dividends in all projects that will pay it's revenues to the token contract.

In order to buy Honest Tokens (HTK), please go to www.honestlabs.win or just send funds to
the TOKEN ICO CROWDSALE contract: 0x474d52047c62545d596b22ee953f290d51fa1ac2!!

You can verify that 0x474d52047c62545d596b22ee953f290d51fa1ac2 is the ICO contract address in Etherscan using Metamask.
Read the variable: tokenSaleContractAddress().

If you read the code you will see that this address can be set only once. The variable tokenSaleContractAddressSetAndMinted should be "true"

If you send money to this contract (token contract address 0x474d52047c62545d596b22ee953f290d51fa1ac2),
your ETHER will be distributed among HTK token holders, but you won't receive any HTK. Prefer to buy HTK in the honestlabs.win webpage.

For Pre-ICO and ICO purposes, tokens transfer won't be allowed yet.
The only addresses that will be allowed to transfer tokens will be the ICO contract and The Honest Tree and Pharaoh Games contracts (for bounty)
After ICO (December 30th 2020, you will be able to transfer tokens and sell them on any exchange)
Check that tokenTransfersAllowed=true;
_________________________________________________

As written in the ICO webpage:
- Total Suppply:  5,000,000
- Pre-ICO and ICO: 85% = 4,250,000 (tranferred to the token ico crowdsale contract)
- Team: 8% = 400,000, sent to the team address
- Consultants: 4% = 200,000, sent to 3 addresses of our 3 Consultants
- Bounty Programs: 6% = 150,000 sent to the bounty address

One example of the bounty program is the 500 free HTK tokens that all 100 fist players of The Honest Tree game will receive.
This 50,000 tokens will be sent from this contract directly to the Honest Tree Game contract. Read the code.
The rest 150,000 will be sent to an address from where we will only send these tokens to our next 3 projects
(See www.honestlabs.win)

_____________________________________________________


The first project to implement this Funds Distribution Payment is The Honest Tree (visit www.honesttree.win)

All root node rewards are distibuted proportionally among Honest Tokens (HTK) holders!!!!

Buy HTK tokens in: http://www.honestlabs.win

IMPORTANT: In order for you to claim your Honest Tree root node's dividends, you must make sure to hold 
Honest Tree Tokens (HTTs) at the time of Honest Tree's root node's withdraw moment (every 15 days).
After any of those moments, you can safely sell or transfer your tokens, even before having withdrawn your funds,
and your past dividends will be honored. However, if you sell or transfer your HTT tokens, 
your won't receive any future Honest Tree's dividends.
*****

What is ERC-2222 ?
The ERC-2222 standard enables the token to represent claims on future cash flow of an asset
such as dividends, loan repayments, fee or revenue shares. This means that any incoming funds
can be distributed efficiently among large numbers of token holders.
Anyone can deposit funds and token holders can withdraw their claims.

The MOST IMPORTANT FEATURE OF ERC-222 STANDARD is that token holders CAN TRANSFER THEIR TOKENS
at any time and can be sure that their PAST CLAIMS TO THE CASH FLOW of the token WILL BE HONORED.

The interface provides methods to deposit funds, to get information about available funds and to withdraw funds.

In this implementation, payments are made in Ethers, and token holders are seen as fractional
owners of any future cash flow (mainly Honest Tree's root node's rewards, distributed very 90 days)

/**
 * @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}.

The Honest Token is the Funds-Distribution Honest Labs' native token.

It is a ERC-20 token with the implementation of the ERC-2222 Fund Distribution Standar.

This means that any funds in ETHER that is sent to this contract (The token contract) will be 
proportionally distributed among token holders, even if token holders sell their tokens before 
having withdrawn their dividends.

This allows token holders to earn dividends in all projects that will pay it's revenues to the token contract.

In order to buy Honest Tokens (HTK), please go to www.honestlabs.win or just send funds to
the TOKEN ICO CROWDSALE contract!!

The see the  TOKEN ICO CROWDSALE CONTRACT please read this contract in Etherscan using Metamask, and read the variable:
tokenSaleContractAddress().
If you read the code you will see that this address can be set only once. The variable tokenSaleContractAddressSetAndMinted should be "true"

Please don't send any funds to this contract, unless you want to experiment on the funds distribution mechanism
(or unless you want to give away Ethers to HTK tokens holdes :P )


For Pre-ICO and ICO purposes, tokens transfer won't be allowed yet.
The only addresses that will be allowed to transfer tokens will be the ICO contract and The Honest Tree Game contract (for bounty)
After ICO (December 30th 2020, you will be able to transfer tokens and sell them on any exchange)
Check that tokenTransfersAllowed=true;
_________________________________________________

As written in the ICO webpage:
- Total Suppply:  5,000,000
- Pre-ICO and ICO: 85% = 4,250,000 (tranferred to the token ico crowdsale contract)
- Team: 8% = 400,000, sent to the team address
- Consultants: 4% = 200,000, sent to 3 addresses of our 3 Consultants
- Bounty Programs: 6% = 150,000 sent to the bounty address

One example of the bounty program is the 500 free HTK tokens that all 100 fist players of The Honest Tree game will receive.
This 50,000 tokens will be sent from this contract directly to the Honest Tree Game contract. Read the code.
The rest 150,000 will be sent to an address from where we will only send these tokens to our next 3 projects
(See www.honestlabs.win)

The first project to implement this Funds Distribution Payment is The Honest Tree (visit www.honesttree.win)

All root node rewards are distibuted proportionally among Honest Tokens (HTK) holders!!!!

Buy HTK tokens in: http://www.honestlabs.win

IMPORTANT: In order for you to claim your Honest Tree root node's dividends, you must make sure to hold 
Honest Tokens (HTKs) at the time of Honest Tree's root node's withdraw moment (every 15 days).
After any of those moments, you can safely sell or transfer your tokens, even before having withdrawn your funds,
and your past dividends will be honored. However, if you sell or transfer your HTT tokens, 
your won't receive any future Honest Tree's dividends.

What is ERC-2222 ?
The ERC-2222 standard enables the token to represent claims on future cash flow of an asset
such as dividends, loan repayments, fee or revenue shares. This means that any incoming funds
can be distributed efficiently among large numbers of token holders.
Anyone can deposit funds and token holders can withdraw their claims.

The MOST IMPORTANT FEATURE OF ERC-222 STANDARD is that token holders CAN TRANSFER THEIR TOKENS
at any time and can be sure that their PAST CLAIMS TO THE CASH FLOW of the token WILL BE HONORED.

The interface provides methods to deposit funds, to get information about available funds and to withdraw funds.

In this implementation, payments are made in Ethers, and token holders are seen as fractional
owners of any future cash flow (mainly Honest Tree's root node's rewards, distributed very 90 days)
