TVL Fee

TVL Fee Explained

The TVL fee is expressed as a percentage of the DTF's Total Value Locked and is applied continuously through a compound interest calculation.

Technical Implementation

The TVL fee is implemented using a compound interest formula:

fee=11−feePerSecondsecondsPassed−1fee=1−feePerSecondsecondsPassed1​−1

Where:

• feePerSecond is set by the DTF Owner (governance)

• secondsPassed represents the time since the last fee calculation

This mechanism ensures that:

• The fee is calculated and accounted for on every user interaction

• Any view functions account for the TVL fee since the last contract update

• The fee accumulates continuously rather than at discrete intervals

Practical Implications

For users and integrators, this means:

• The TVL fee effectively acts as a continuous management fee

• The longer assets remain in the DTF, the more fees accrue

• The displayed value of Index DTF tokens will gradually decrease relative to the underlying assets, reflecting the accrued fees
