System Overview

Inverse Arena is a blockchain-based elimination game where players stake assets, make binary choices (Head/Tail), and the minority survives each round. The last player standing wins the entire prize pool plus accumulated yield from Real-World Asset (RWA) protocols.

Key Features

  • Multi-Currency Support: USDT0, mETH, and native MNT
  • RWA Yield Generation: Stakes automatically generate 4-6% APY during gameplay
  • Provably Fair: Chainlink VRF for random outcomes
  • Intelligent Matchmaking: Solves the "waiting room problem"
  • NFT Achievements: Player progression and rewards
  • Multiple Game Modes: QuickPlay, Scheduled, and Private rooms

Contract Interactions

GameManager ↔ YieldVault

  1. Deposit Flow:

    • GameManager calls depositUSDT0() or depositMETH() when game is created/joined
    • YieldVault stores deposit and calculates shares
    • GameManager tracks yieldProtocol in game state

  2. Yield Query:

    • GameManager calls getAccumulatedYield(gameId) during game completion
    • YieldVault calculates time-weighted yield

  3. Distribution:

    • GameManager calls distributeYield(gameId, winner) to pay winner
    • YieldVault transfers principal + yield to winner

  4. Snapshots:

    • GameManager calls emitYieldSnapshot(gameId) between rounds
    • Provides real-time yield tracking

GameManager ↔ NFTAchievements

  1. Minting:

    • GameManager calls mintAchievement(winner, 0, gameId) on game completion
    • NFTAchievements mints "First Victory" NFT

  2. Verification:

    • GameManager can check hasAchievement() for conditional logic
    • Used for streak tracking, loyalty tiers, etc.

Matchmaking ↔ GameManager

  1. Game Creation:

    • Matchmaking calls createQuickPlayGame() or createPrivateRoom()
    • GameManager creates game and returns gameId

  2. Player Joining:

    • Matchmaking calls joinGame(gameId) for each matched player
    • GameManager adds players and handles deposits

Game Flow

Complete Game Lifecycle

1. GAME CREATION
   ├─ Player calls createQuickPlayGameUSDT0()
   ├─ GameManager creates game structure
   ├─ Deposits entry fee to YieldVault
   └─ Game status: Waiting

2. PLAYER JOINING
   ├─ Players call joinGame(gameId)
   ├─ Entry fees deposited to YieldVault
   ├─ Auto-start when minPlayers reached
   └─ Game status: InProgress

3. ROUND EXECUTION
   ├─ Players call makeChoice(gameId, choice)
   ├─ When all chosen: Request Chainlink VRF
   ├─ VRF callback: fulfillRandomWords()
   ├─ Process round: Minority survives
   ├─ Eliminate majority players
   └─ Advance to next round OR complete game

4. GAME COMPLETION
   ├─ Last player standing wins
   ├─ Calculate yield from YieldVault
   ├─ Distribute principal + yield to winner
   ├─ Mint achievement NFT
   └─ Game status: Completed

Round Processing Logic

1. All active players make choices (Head/Tail)
2. Count choices: choiceCounts[Head] vs choiceCounts[Tail]
3. Determine minority choice (fewer votes)
4. If tie: Use VRF randomness to break tie
5. Eliminate players who chose majority
6. Survivors advance to next round
7. Repeat until 1 player remains

Yield Accumulation

Time 0: Deposit 1000 USDT0 → YieldVault
Time 5min: Yield = 1000 * 0.05 * 300 / (31536000 * 10000) = ~0.48 USDT0
Time 10min: Yield = 1000 * 0.05 * 600 / (31536000 * 10000) = ~0.95 USDT0
Time 15min: Yield = 1000 * 0.05 * 900 / (31536000 * 10000) = ~1.43 USDT0

Winner receives: 950 USDT0 (principal - 5% fee) + 1.43 USDT0 (yield)

Yield Generation Flow

Deposit Flow

Player Stakes 100 USDT0
    ↓
GameManager receives USDT0
    ↓
GameManager.approve(YieldVault, 100)
    ↓
GameManager.depositUSDT0(gameId, 100)
    ↓
YieldVault.safeTransferFrom(GameManager, YieldVault, 100)
    ↓
YieldVault calculates shares
    ↓
YieldVault stores GameDeposit with timestamp
    ↓
Yield starts accumulating immediately

Yield Calculation

Formula: yield = principal * apy * timeElapsed / (SECONDS_PER_YEAR * BASIS_POINTS)

Example:

  • Principal: 1000 USDT0
  • APY: 5% (500 basis points)
  • Time: 15 minutes (900 seconds)
  • Calculation: 1000 * 500 * 900 / (31536000 * 10000) = 1.43 USDT0

Distribution Flow

Game Completes
    ↓
GameManager.getAccumulatedYield(gameId)
    ↓
YieldVault calculates yield based on time elapsed
    ↓
GameManager.distributeYield(gameId, winner)
    ↓
YieldVault transfers principal + yield to winner
    ↓
YieldVault updates TVL and protocol totals
    ↓
YieldVault records yield snapshot
