Chess Polygon Whitepaper


From the team:

“First, we believe that crypto projects are created for people and should not be difficult to understand. We wrote the Whitepaper in the form of a presentation to ensure clarity and prevent an overabundance of technical terms. Below, we have tried to convey our idea unambiguously and intelligently. Of course, you can always relate your questions to us by mail or Telegram.”

Ode to chess

Chess is one of the intellectual games known to humankind for over 1500 years. Almost every civilized person has played chess at least once in his or her life. The history of chess is associated with great victories and tragedies, brilliant people, and exciting ideas. Chess has an amazing ability always to remain relevant. Moreover, despite the traditions and rules, they are ready for constant development.

In turn, blockchain is one of the youngest and most promising technologies. It is the use of cryptocurrency in chess that can open up new facets of this game and become a pleasant training of your intellect and an opportunity to earn money while playing. Combining tradition and innovation, we have created Chess Polygon, the chess game that allows you to monetize intelligence.

Project idea

The global idea of the Chess Polygon project is to use the chess game as a tool for cryptocurrency mining. As you know, the mining process itself implies the solution to a particular task. As a result, miners receive a reward in cryptocurrency.

The Chess Polygon project presents a new concept called "intelligent mining". The task that players need to solve is to defeat the opponent, and the rewards are given in STEIN tokens.

Project goals

Combining the ancient chess game and the latest blockchain technology and declaring the goals of the project, Chess Polygon defines the following purposes:

To popularize the chess game in general, and particularly among the younger generation, by adding the possibility of monetization directly into the gameplay.

To provide the crypto community with an alternative green mining solution with a near-zero carbon footprint.

To enable gamers from the world of play-to-earn games to expand their respective playing field by becoming more familiar with chess and intellectual gaming.

To offer a public cryptocurrency mining solution that allows users to "make money using their mind".

Project audience

Chess fans

It has historically been difficult for chess players to monetize their hobby, where an almost only way to obtain price was participation in tournaments. The tournament's drawback was that they were the prerogative of grandmasters and not amateur chess players. In addition, to get a cash prize, you needed to get to the prize-winning place, which the tournament granted to only a small number of its participants.

The Chess Polygon project integrates cryptocurrency into the gameplay, allowing every participant, whether amateur or grandmaster, to monetize every victory, regardless of his or her knowledge, experience, or world ranking.

Crypto community

It's no secret that cryptocurrency mining equipment is quite expensive and consumes a large amount of electricity. This circumstance has led to a heated debate over the environmental friendliness of the mining process and its impact on the environment.

The Chess Polygon project introduces "intelligent mining", an alternative green mining solution for the crypto community. No more GPU or ASIC is required. Now the players' time, attention, and intelligence is the computing power!


The world of modern youth is unimaginable without video games. Gamers spend many hours honing their skills, but it is not always possible to monetize their time. With an understanding of strategy, knowledge of tactics, and logic, gamers will be able to defeat their opponents and earn cryptocurrency. Training your chess skills will help you become the "Global Elite" in intellectual games.

The Chess Polygon project invites gamers to take advantage of their gaming experience and try their hand at intellectual gaming. By getting to know chess better, gamers will significantly enrich their gaming experience and expand their respective playing field.


Many people have a great desire to learn how to play chess. Some even tried. But, for various reasons, this game has never become their favourite. Cryptocurrency can serve as an excellent incentive to get acquainted with this fascinating game or resume chess battles with rivals.

The creators of The Chess Polygon project designed it so that the system automatically selects opponents with approximately the same rating. This project allows you to evenly distribute the "power" in the network and maintain a balance between amateurs and professionals.


The worlds of investment and chess are similar. They unite purposeful people who look into the future. Both investors and chess players have one more thing in common – they both have a habit of thinking through their actions several steps ahead.

The Chess Polygon project offers a unique opportunity to invest not only in the project token, but also directly in individual players. An Investor can act as a Manager, create his chess team and receive passive income without playing chess. Who knows, maybe with your help, the world will get a new Champion.


Chess Polygon

Chess Polygon is a game that will be available as an app for Android or iOs mobile devices. The game application is developed using Node.js, React Native, and other technologies. Several smart contracts written in Solidity are responsible for STEIN and NFT tokens transactions.

The game mechanics are no different from classical chess rules; we are not changing chess but adding modern technologies to it.

For defeating rivals, players are awarded STEIN tokens, which can be used within the Chess Polygon ecosystem or transferred to an external wallet, and disposed of them at the discretion of the players. In addition, players receive NFT tokens for personal achievements. They can be collected, sold, used within the game, or utilized as a ticket to enter Chess Polygon tournaments. You can find detailed information about the rules and distribution of rewards in the Game Modes section.

There are several game modes that take into account different user preferences:

Mining. Here, players earn STEIN and NFT tokens by defeating opponents selected by the system at random.
Challenge. This mode allows you to choose opponents and play against your friends or unknown worldwide opponents.
Investor. Allows the user to create his team and receive a part of the reward for the victories of each team member without having to play chess himself.
Observer. In this mode, you can follow other players' games in real-time.
Practice. Here you can practice your gaming skills by solving tactical tasks on a chessboard.
Tournament. Monthly tournaments with a prize pool in STEIN and NFT rewards for the top places.


Mining Mode


In Mining mode, players cannot choose their opponents. Instead, the system selects players randomly so that opponents have the closest possible rating. This way of selecting allows you to evenly distribute the "power" in the network and maintain a balance between amateurs and professionals.

It is essential to understand that for the player selection system to work correctly, the player needs to play several games. The more games held, the more accurate the selection system would work.

Time to play

In this mode, the game time is strictly limited. Each player has 15 minutes of playing time for the entire game. Accordingly, a chess game can last up to 30 minutes. If none of the opponents can checkmate during this time, the system will count defeat to the one who used up his playing time first.

Player Rating

All players are assigned an initial rating upon registration. The number of wins directly affects its value changes and losses in chess games played in the Mining mode. All games played in the Mining mode are taken into account to calculate the rating.

Daily limits

The number of games per day is unlimited. However, the number of winnings in 24 hours rewarded with STEIN tokens is limited to 10. In other words, players get STEIN for the first ten wins within 24 hours. It is done to distribute the tokens more evenly among the players. When the limit is reached, the player can continue to play in Mining mode, but no rewards will be awarded. Limits are reset at 00:00 GMT.

STEIN awards

Players receive STEIN tokens for defeating opponents. The amount of STEIN awarded in case of winning depends on several factors. Firstly, it depends on the selected game mode, and secondly, on the number of STEIN placed on the staking balance (see the Staking section for more information).

Players receive STEIN tokens for the first ten wins within 24 hours. Tokens are awarded only for wins, but neither defeats nor draws are awarded. However, in case of defeat, players do not lose the tokens earned earlier.

A player must put at least 10 STEIN on the staking balance to get a STANE for a win. This condition is equal to 0.01 STEIN received by the player for winning. When replenishing the staking balance for ten tokens, the reward for winning increases by 0.01 STEIN.


Staking balance 120 STEIN = 0.12 STEIN per win.
Staking balance 1200 STEIN = 1.2 STEIN per win.
Staking balance 10000 STEIN = 10 STEIN per win.
The maximum staking balance cannot exceed 10,000 STEIN.

Staking has no time limit. The player receives relevant rewards for winning as long as STEIN is in his staking balance. If a player withdraws tokens from staking, his reward for winning will decrease to the initial level. Players can withdraw STEIN from staking at any time. Tokens are returned to the principal balance at 00:00 GMT.

As STEIN tokens enter circulation, the amount of the reward for defeating an opponent decreases proportionally. For more information on reward reductions, see the STEIN Token Distribution section.

NFT Rewards

Players receive NFT tokens for personal achievements in the game, while all winnings in Mining mode are considered. NFT can be used:

For additional games in the Mining mode (in addition to the daily limit).
As a ticket to participate in Chess Polygon chess tournaments.
For sale on the NFT marketplace.
For collecting to confirm personal achievements in chess.

Players receive NFT tokens for the following personal achievements:

100 wins
Players receive 1 NFT for every 100 wins. You can exchange that NFT for ten additional games in Mining mode (in addition to the daily limit) or use it as a ticket to one Chess Polygon chess tournament.

1000 wins
Players receive 1 NFT for every 1000 wins. You can exchange that NFT for hundred additional games in Mining mode (in addition to the daily limit) or use it as a ticket to one Chess Polygon chess tournament.

Player of the Month
The player who wins the most games during the month gets 1 NFT. You cannot exchange this NFT for additional games in Mining mode, but its owner gets the opportunity to participate in Chess Polygon tournaments an unlimited number of times.

Player of the Year
The player who wins the most games during the year gets 1 NFT. You cannot exchange this NFT for additional games in Mining mode, but its owner gets the opportunity to participate in Chess Polygon tournaments.

Champion of the month
The player who has the highest number of wins among all participants on the last day of the month receives an NFT. Wins are taken into account for all the time that has passed since the player's registration. This NFT cannot be exchanged for additional games in Mining mode, but its owner gets the opportunity to participate in Chess Polygon tournaments an unlimited number of times.

Champion of the Year
The player with the highest number of wins among all participants as of December 31 receives an NFT token. Winnings are counted for the entire time since the player's registration on the platform. This NFT cannot be exchanged for additional games in Mining mode, but its owner gets the opportunity to participate in Chess Polygon tournaments an unlimited number of times.

A unique NFT design has been developed for each category mentioned, but it is repeated within the category.

Challenge Mode


Using this mode, the players choose their opponents, including from the list of friends.

Time to play

In this mode, users can set a time limit for the game at their discretion, by agreement with the opponent, ranging from one to 120 minutes.

Player Rating

The system does not consider games played in the Challenge mode for calculating the rating.

Daily limits

There are no limits on the number of games within 24 hours.

STEIN awards

The players set the amount of STEIN that the winner of the game will receive on their own. To do this, both opponents should have enough STEIN in the balance. The commission of Chess Polygon is 10%.


Player 1 creates a game with a 100 STEIN reward for winning; Player 2 accepts the challenge and contributes 100 STEIN. The winner receives 180 STEIN, and Chess Polygon's commission is 20 STEIN.

Players can create "friendly parties" with no rewards for winning; however, for parties in the Challenge mode, staking balance is not considered and it does not affect rewards.

NFT Rewards

When users play games in the Challenge mode, it does not count towards NFTs.

Investor Mode

The Investor mode allows the user to act as a Manager. For example, the Manager can "hire" other players to form his team. For the victories of the team members playing in the Mining mode, the Manager receives STEIN tokens in the amount of a pre-agreed percentage.

To receive a percentage payment from a player of his team, the Manager must delegate STEIN tokens to the Player, which will be placed on his staking balance. Thus, the Manager can influence the increase in the reward of the Player who is conducting games in the Mining mode. The maximum number of tokens delegated to team members cannot exceed 10,000 STEIN. Accruing interest to the Manager and rewards to the Player is automatic and does not require human intervention.


The Manager delegates 1000 STEIN to the Player with the distribution of rewards 50/50. The Player receives tokens on the staking balance, which increases his reward for winning up to 1 STEIN. If the Player defeats the opponent, both the Player and the Manager automatically receive 0.5 STEIN each.

Delegating STEIN to team members is safe and eliminates the risk of losing or not returning tokens. Delegated tokens remain under the complete control of the Investor (Manager). The Player cannot use them and cannot withdraw them from the staking balance. However, the Player has the option to opt-out of the partnership. In this case, the tokens are returned to the Manager. The Manager, in turn, can also cancel the partnership with the Player and return the delegated tokens to his balance. STEIN tokens will be credited to the Manager's balance at 00:00 GMT.

The manager has the privilege to delegate tokens to several players. However, the Player himself can only be on one team. At the same time, the Player's staking balance should not exceed 10,000 STEIN, including delegated tokens.

Observer Mode

In the Observer mode, users registered in the application can watch other players' games in real-time. For example, you can select the Observer mode both to observe the game process of unfamiliar users and among friends.

Using this mode is helpful for beginner chess players who can follow the games of more experienced colleagues and gain experience.

Practice Mode

The most effective way to improve your chess skills is to solve tactical exercises. In this mode, players will have access to various practical tasks. With the help of a good selection of exercises, you can work out any game elements at any stage of chess. Most experts consider solving chess tasks the most effective method of learning and improving chess skills. Practice your skills, find the right solutions and return to Mining mode with renewed vigor!

Tournament Mode

The Chess Polygon team plans to hold monthly tournaments with a prize pool in STEIN and NFT rewards for the top places. Details about the conditions and rules are announced before announcing the tournaments themselves. Announcements and news are published in our communities..



The Chess Polygon project developers chose the Polygon Blockchain ecosystem (previously called Matic Network), as its main network was launched in the spring of 2020.

The distinctive features of the chain are a high degree of decentralization, low fees, high transaction speed, the ability to scale up to millions of transactions per second, the ability to integrate with DeFi projects already running on Ethereum, and, of course, a close-knit community.


STEIN is the native token of the Chess Polygon project. The developers named the token after Wilhelm Steinitz, the first generally recognized World chess champion, considered the "father of positional chess". The STEIN token is built on the Polygon blockchain, a fast, reliable, and secure protocol focused on scalability and mass adoption. Players receive STEIN for defeating their opponents.

Token distribution

Chess Polygon token distribution

 70% For players

70% of the entire STEIN supply is intended solely to reward players for defeating rivals (in the Mining game mode). This amount of STEIN will be sent to a smart contract that controls the payment of rewards for winnings. These tokens will get into circulation only through players' victory over rivals.

The number of STEIN received by players for defeating rivals in the Mining mode will decrease in direct proportion to the decrease in the balance of the smart contract. Each time the next 10% of tokens are put into circulation, the amount of STEIN received for winning will be reduced by 10%. Players can check balance and transaction history at any time.

Public address: 0xC8b8609E632B3e54EDFBed0D866968d2AAa0fDcC


Knowing that the initial number of tokens intended to reward wins is 700,000,000 STEIN, one can calculate that the reward will be reduced when 700,000,000 x 0.1 = 70,000,000 STEIN are put into circulation. The balance of the smart contract will be 630,000,000 STEIN.

The subsequent reduction in rewards will occur when 630,000,000 x 0.1 = 63,000,000 STEIN are put into circulation, and the balance of the smart contract will be 567,000,000 STEIN, etc.

Such a system of reducing rewards for victories resembles Bitcoin halving cycles. Its net result is the following: players will start receiving less STEIN for winning with equal time and effort. In addition, users can increase the price when selling earned tokens to keep mining profitability at the same level. This calculation, in turn, should have a positive impact on the price of STEIN as a whole and bring a deflationary component to the Chess Polygon economy.

 18% STEIN at the disposal of the project

18% of the STEIN emission remains at the disposal of the project. This part of the tokens creates a reserve fund that can be used for the future needs of the project. There are no plans to sell these tokens.

Public address: 0x10C40a4568FececE7c71DFFE539DA1D97B054376

 10% For token sale and listing

10% of all STEIN issuance is dedicated to STEIN's public sale rounds and listings on the crypto exchanges. Tokens sold during the sale period will be available for trading. There is no token blocking period. The listing will take place after the end of the sale period.

Public address: 0xAFbd569aa6Bde7b739517B2078DDbB47043d1Bb4

 1,9% For STEIN private sale round

1.9% of the entire STEIN offer is allocated for a private token sale round. Would you like to purchase STEIN before the public sale and support the project? Write to us on Telegram. Telegram. You need to wait for the operator's response to complete the purchase. First-line investors who want to support the project at the launch stage will be able to purchase tokens at the lowest price.

Funds raised at this stage are primarily intended for:

Marketing and advertising campaigns to attract the audience's attention and popularize the Chess Polygon project.
Paying the costs of conducting STEIN Public Sale.
STEIN smart contract audit.

Staking in Chess Polygon increases the amount of STEIN tokens that a player receives for defeating opponents in Mining mode. The more STEIN locked into the staking balance, the higher the reward for winning. The maximum balance of a staking wallet cannot exceed 10,000 STEIN.

Staking has no time limit and is perpetual. The player can transfer STEIN from the staking balance to the principal balance at any time. After a request to withdraw STEIN from staking, tokens will be credited to the main wallet at 00:00 GMT.

To receive tokens for wins, a player must stake at least 10 STEIN, equal to 0.01 STEIN per win. For every ten token increase in staking balance, rewards increase by 0.01 STEIN.


Staking balance 120 STEIN = 0.12 STEIN per win.
Staking balance 1200 STEIN = 1.2 STEIN per win.
Staking balance 10,000 STEIN = 10 STEIN per win.

From an economic point of view, the staking solution has several advantages over classic NFT games, where as an initial investment, users are most often asked to buy game characters in the form of NFT tokens. The main differences can be highlighted:

Players can invest in staking exactly as much as they see fit, and not the amount that the creators of the NFT project ask for purchasing a game characters.

In the case of NFT characters, the total amount of the initial investment is locked in a non-fungible token, making partial withdrawals impossible. In turn, Chess Polygon staking allows players to withdraw part or all of their investment at any time.

The use of the STEIN token for staking creates conditions for market relations between users, in which new players act as buyers and generate demand of the token. Active users can sell previously mined STEIN (offer).

Supply and demand conditions within one token in the in-game economy should lead to an increase in STEIN trading volumes, which will undoubtedly be a positive factor.


We plan to create our own NFT Marketplace, where users will be able to sell and buy NFTs obtained in the game and create their chess-themed collections. Follow the announcements and news of the project in our communities.
