How It Works

1. Register an index token with a fee rate and recipient

2. Anyone can call accrueFee() to trigger fee collection

3. Module mints new index tokens to the fee recipient, proportional to:

• Current total supply
• Annual fee rate (basis points)
• Time elapsed since last accrual

Fee Rate Changes

• 48-hour timelock on all fee rate changes
• Maximum fee rate capped at 5% annually (immutable)
• Two-step process: proposeFeeRateChange() → wait 48h → executeFeeRateChange()
