From d80b101617671ccea258954af09efdfe7ec11c54 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 6 Nov 2025 17:38:12 +0000 Subject: [PATCH 1/3] feat: add create-hathor-dapp template with Hathor Dice example - Add CLI tool for scaffolding Next.js Hathor dApps - Include complete Hathor Dice game with nano contract integration - Add wallet components (ConnectWallet, WalletInfo, NetworkSwitcher) - Implement dice game components with animations and controls - Add liquidity pool functionality for LPs - Include comprehensive hooks for contract interactions - Add utility libraries for probability calculations and formatting - Create responsive UI with Tailwind CSS - Include detailed documentation and examples - Add How It Works page explaining the game mechanics The template demonstrates: - MetaMask Snap integration - Nano contract interactions (deposits, withdrawals, method calls) - Provably fair dice game with customizable bets - Liquidity providing with ROI tracking - Real-time balance and statistics - Game history with localStorage persistence Users can run 'npx @hathor/create-hathor-dapp my-dapp' to get started. --- packages/create-hathor-dapp/README.md | 177 +++++++++++

How Hathor Dice Works

+ +
+ {/* Game Mechanics */} +
+

šŸŽ² Game Mechanics

+
+

+ Hathor Dice is a provably fair dice game where you choose your bet amount and win threshold. + The game generates a random number between 0 and 99.99, and you win if the result is{' '} + under your chosen threshold. +

+
+

Example:

+
    +
  • ā€¢ You bet 100 HTR with a threshold of 50.00
    • +
  • ā€¢ The dice rolls 42.15
    • +
  • ā€¢ Since 42.15 {'<'} 50.00, you win!
    • +
  • ā€¢ Your payout is calculated based on the multiplier
    • +
+
+
+
+ + {/* Probability & Payouts */} +
+

šŸ“Š Probability & Payouts

+
+

+ The payout multiplier is calculated based on your win chance and the house edge (1.90%): +

+
+ Multiplier = (1 / Win Chance) Ɨ (1 - House Edge) +

+

šŸ”’ Provably Fair

+
+

+ This game uses Hathor's nano contracts to ensure fairness. The random number generation happens + on-chain and cannot be manipulated by the house or players. +

+
+

Why it's provably fair:

+
    +
  • āœ… Random numbers generated using blockchain entropy
    • +
  • āœ… All game logic runs in a nano contract (immutable)
    • +
  • āœ… Every bet is recorded on-chain
    • +
  • āœ… You can verify results using the transaction ID
    • +
+
+
+
+ + {/* Nano Contracts */} +
+

āš” Nano Contracts

+
+

+ Hathor Dice is powered by nano contracts - lightweight smart contracts on the Hathor Network. + When you place a bet: +

+
    +
  1. Your HTR is deposited into the contract
    2. +
  2. The contract generates a random number
    3. +
  3. The contract calculates your payout based on the result
    4. +
  4. Winnings are automatically added to your contract balance
    5. +
  5. You can claim your balance at any time
    6. +
+
+

+ Note: Your balance stays in the contract until you claim it. This saves on + transaction fees if you want to play multiple rounds! +

+
+
+
+ + {/* Liquidity Pool */} +
+

šŸ’° Liquidity Pool

+
+

+ The game is backed by a liquidity pool where anyone can provide HTR to earn from the house edge. +

+
+
+

For Players

+

+ The pool ensures there's always liquidity to pay out big wins. Max bet is limited to protect + the pool. +

+
+
+

For Providers

+

+ Earn passive income from the 1.90% house edge. Your share of profits is proportional to your + contribution. +

+
+
+

āœ… Benefits

+
    +
  • ā€¢ Earn passive income from house edge
    • +
  • ā€¢ Proportional share of all profits
    • +
  • ā€¢ Withdraw anytime (with available liquidity)
    • +
  • ā€¢ No lockup period required
    • +
+
+
+

āš ļø Risks

+
    +
  • ā€¢ Players may win big, reducing pool value
    • +
  • ā€¢ Withdrawal limited by available liquidity
    • +
  • ā€¢ Smart contract risks
    • +
  • ā€¢ Value fluctuates with game outcomes
    • +
+
+
+
+

+ Example: If you provide 1,000 HTR to a 10,000 HTR pool, you own 10% of the pool. + When players lose 100 HTR to the house edge, you earn 10 HTR (10% of 100 HTR). +

[PATCH 2/3] fix: add useCallback to hooks to fix ESLint exhaustive-deps warnings - Wrap async functions in useCallback in useHathorWallet hook - Wrap async functions in useCallback in useContractBalance hook - Wrap sync function in useCallback in useGameHistory hook - Wrap async functions in useCallback in NetworkSwitcher component - Wrap async functions in useCallback in WalletInfo component - Add proper dependency arrays to all useEffect hooks - Add package-lock.json for create-hathor-dapp CLI dependencies These changes prevent ESLint warnings about missing dependencies and ensure hooks work correctly with React's dependency system. --- packages/create-hathor-dapp/package-lock.json | 173 ++++++++++++++++++ .../components/wallet/NetworkSwitcher.tsx | 14
