Durak Crypto — Poker & Durak - Sell Project

KEY HIGHLIGHTS Custom-built Durak game engine Developed entirely from scratch as a server-authoritative implementation with a complete ruleset: Attack / defense / transfer phases Throw-in mechanics Trump logic Loser resolution 2–6 player tables Not a re-skinned white-label casino script. Texas Hold'em Poker included No Limit Texas Hold'em, 6-max and Heads-up tables Stake levels from 5 to 100 USDT Global game switcher: Durak and Poker are cleanly separated across lobby, profile, history and leaderboard Working on-chain money loop Real USDT deposits and withdrawals are live on TON and BSC (BEP-20), processed end-to-end. BTC deposits are also supported: BTC is automatically converted to USDT at market rate and credited to the player's balance (usually within 30 minutes). Withdrawals are paid in USDT (TON or BSC). Includes: HD wallets (BIP39) Deposit monitoring Idempotent transaction handling This is one of the hardest, riskiest, and most expensive parts of building a crypto gaming platform, and it is already implemented and verified. Provably fair Commit–reveal scheme with a server seed Per-player client seeds, editable by the player Public drand (League of Entropy) randomness drawn after all seats are filled Players can recompute the deck and verify every game themselves Live production platform, not an MVP The platform is fully developed, deployed, and operational.

CUSTOMERS Durak Crypto targets crypto-native gamers, poker players, and Durak enthusiasts. Durak is one of the most popular card games across CIS and Eastern European markets, providing a naturally existing audience. Poker opens the platform to a global audience.

Durak Crypto is also listed on tg.app and other game directories, providing additional visibility and discovery. FINANCIALS Early-revenue stage: the platform is fully developed and live, but has not yet generated meaningful trading volume. Multiple users have successfully completed real on-chain deposits, confirming the complete payment flow works end-to-end: Deposit detection Balance crediting Gameplay using deposited funds This project is being sold as a proven technical asset, not as a business with an established revenue history.

HOW THE PLATFORM MAKES MONEY Durak Crypto generates revenue through a configurable platform fee (rake) on real-money games between players. Current rake: 5% per game...
