HouseBuffer

Shared USDC reserve backing one or more LiquidityVault instances. Collects liquidity fees from vault redemptions and provides float top-ups when vault idle reserves run low.

Role

The HouseBuffer serves two functions:

1. Fee sink — receives 0.5% liquidity fee from every vault redemption
2. Float provider — transfers USDC to vaults when their idle reserve drops below 50% of target

Not an insurance fund

The HouseBuffer does not calculate gap coverage and does not insure against market losses. It provides liquidity services. If vault positions fail, the HouseBuffer cannot make investors whole.

Revenue Model

Daily fee income = dailyRedemptionVolume × 0.5%

// At $2M TVL, 1% average daily redemption:
// Daily volume  = $20,000
// Daily fee     = $100
// Monthly fee   = ~$3,000
// Annual fee    = ~$36,500
// House capital = $240,000 (12% of TVL)
// Fee ROI       = ~15% annually on committed capital
