What is HiMeet (Rook Club)?

HiMeet is a social network with free worldwide classifieds (ads and chat are translated into your language), 18+ dating, and online chess where players can stake USDC on Polygon. It also has free chess puzzles, tournaments and chess NFTs.

Is there dating on HiMeet?

Yes. Dating is free and for adults only (18+): profiles with up to 3 photos, filters, likes, matches and private chat.

Which currency and network does HiMeet use?

USDC on the Polygon network, plus a small amount of POL for network fees.

The fee is 10% of the pot, so the winner receives 90%. Draws and cancelled games are refunded in full.

Who holds the stakes?

A smart contract holds the stakes, and the winner claims the prize from it.

What is a chess NFT on HiMeet?

In the NFT Studio you pick a move from your own finished game and combine it with a cartoon chess piece, a mood and a background. The result is an ERC-721 NFT on Polygon that shows the board position of that move. Each move of a game can become an NFT only once.

Can I sell a chess NFT on OpenSea?

Yes. The NFTs are standard ERC-721 tokens on Polygon with 5% creator royalties (ERC-2981), so they can be listed and traded on OpenSea.

How do I play chess for crypto?

Sign in or connect a wallet, get USDC and a little POL on Polygon, create a game with a stake or join one in the lobby, and play. The winner claims 90% of the pot from the smart contract.

What are HiMeet classifieds and are chats translated?

HiMeet has an international classifieds board in the Rook Club community: for sale, wanted, rent, jobs and services in any country and city. Ads and chat messages can be translated into your language with one tap. Your first ad is free.

Can I practise for free?

Yes. You can play chess against a bot or a friend for free without any stake.

HiMeet (Rook Club): Whitepaper

Version 0.1 · 8 November 2026 · https://serwmwser.github.io

This document describes the project as it works today and what is planned. It is not investment advice and does not promise any income.

1. Summary

HiMeet is a social platform for chess players and their friends. It combines a social network called Rook Club, free classifieds for the whole world with chat translation, 18+ dating, puzzles, tournaments and online chess where players can put USDC stakes on the Polygon network.

Stakes are held by an open smart contract, not by the website. The winner of a staked game receives 90% of the pot and the fee is 10%.

2. The problem

Chess players who want more than a casual game have few places where the result carries a stake and the money is held by a neutral party.
Communities, classifieds and dating live in separate apps, and cross-border classifieds suffer from language barriers.

3. What the platform offers

Rook Club: a social feed, profiles, messages and voice messages.
Classifieds: the first ad is free, with built-in chat translation between languages.
Dating (18+): profiles and chat.
Chess: free games against a bot or a friend, and games for USDC stakes.
Puzzles and tournaments: free mate-in-1, mate-in-2 and mate-in-3 puzzles with XP, and free hourly arenas with points, badges and cups.
Chess NFTs: a move from your own finished game can become an ERC-721 NFT on Polygon.
Referral programme Eternal Gambit: invite friends with your personal link and receive a share of the fee from their paid games: 10%, 20% once you have 21 friends and 30% from 101 friends. A friend counts after their first paid game; income is not guaranteed.
Languages: the interface is available in English and Russian; more languages are planned.

4. How a staked game works

Sign in or connect a wallet.
Hold USDC and a little POL (for network fees) on the Polygon network.
Create a game with a stake, or join one in the lobby. Both stakes go into the smart contract.
The game server applies the rules of chess and reports the result to the contract.
The winner presses Claim and receives 90% of the pot. A draw or a cancelled game is refunded in full.

5. Smart contracts

ChessEscrow (stakes): 0xaf8714656261dc770A41857706FF4b2f495e92e9. GameNFT (chess NFTs): 0xD929546324c0d675C16C8005F2df59D79AEFf87B. Both are on Polygon and their source code is verified on Polygonscan.

The maximum stake is limited by the contract. The contracts have not had a paid third-party audit. Game results are reported to the contract by a server-side oracle key, so players trust the game server to report results honestly.

6. Money and fees

Currency and network: USDC on Polygon; POL pays network fees.
Chess stakes: 10% fee on the pot, the winner gets 90%.
Classifieds: the first ad is free; extra ads 1 USDC per 30 days; renewal 1 USDC; top placement 3 USDC for 7 days.
Chess NFT: 1 USDC plus the network fee; 5% creator royalties where marketplaces honour them.
Signing in, the feed, dating, puzzles, tournaments and free chess are free.

7. Safety and fair play

Age 18+ only. Responsible play information is on the site.
Wallet sign-in: the site never asks for a password and never sees your private keys.
Moderation tools for posts, ads and profiles; blocking and reporting.
Rules of chess are enforced by the game server, including clocks and draw rules.

8. Planned features

Calls between profiles.
The TCH in-app token (see the TCH whitepaper).
More interface languages.

9. Risks

You can lose your stake. Blockchain transactions cannot be undone.
Smart contracts may contain errors; the contracts have not been independently audited.
Results depend on a game server and its oracle key.
Rules for cryptocurrencies and games differ by country; you are responsible for following the laws of yours. The service may be unavailable in some countries.
Play only with money you can afford to lose.
