## Protocol Key Parameters
- Total Token Supply: 1,000,000,000 (1 Billion) tokens with 18 decimals.
- Bonding Curve Allocation: 800,000,000 (80%) available for immediate trading on curve.
- DEX Liquidity Pool Seed: 200,000,000 (20%) reserved and minted directly to Uniswap v4 Hook Pool upon curve graduation.
- Bonding Curve Model: Virtual Constant Product AMM (vCPMM): (x + x_0)(y + y_0) = k.
- Trading Fee: 1.0% flat (100 basis points).
  - 50% (0.50%) to Token Creator
  - 30% (0.30%) to Protocol Treasury
  - 20% (0.20%) to HootV2BuybackVault
- Graduation Condition: Once 800,000,000 tokens are sold, curve graduates automatically. 100% of collected quote assets and 200M reserved tokens are deposited to Robinhood Swap AMM; LP tokens are burned forever to address(0).
