# Fee Structure

**HOLI pool type:** Uniswap V4 full-range hook.

**Base V4 LP fee:** the pool key stores a static **0** fee — not a dynamic-fee sentinel. Standard pool scanners therefore read **0% LP fee**. The Hook separately charges a HOLI sell **1%**, paid in HOLI and **burned in the same swap**. It is not an LP fee and is not credited to the LP, Treasury, or a developer wallet. The pool curve receives the remaining **99%** of a HOLI sell. Fill and slippage affect trade price, not official NAV. Official NAV is **1× the external leg**. **Fixed by the hook.** Community governance decides **which pools to open**; it does **not** change this asymmetric exit tax.

Do not mix this with the SHYT **tax**. SHYT tax **20%** still funds development. The HOLI sell burn does not.

Protocol-owned pools are Uniswap V4 **full-range**. Each NAV LP is independently priced vs HOLI. Positions are **external-asset / HOLI only** — no StockA/StockB.

## Asymmetric fee

| Direction | V4 LP fee | Hook exit tax |
| --- | --- | --- |
| **Buy HOLI** (spend the external asset, take HOLI) | **0** | **0** |
| **Sell HOLI** (spend HOLI, take the external asset) | **0** | **1% HOLI burn** |

Buying HOLI into the hub is cheap. Leaving through the hub pays 1%. That is **fixed by the hook**, not a HOLI transfer tax, and not a <Md expr="w" /> parameter. The hook takes 1% of the HOLI input and burns it atomically; the remaining 99% enters the [standing take-up](/pol) curve and the pool releases the external asset along that curve. The burn and slippage affect the **fill**, not dashboard NAV.

## Burn destination

The 1% HOLI sell amount is burned immediately. There is no accrued fee balance, no `collect` or `harvest` path for it, and nothing from this mechanism belongs in Treasury assets or NAV. Developers receive none of it.

The burn is a supply sink, not Treasury income and not a promise of price support.

SHYT **tax** **20%** still funds development. That is a trading tax on SHYT, not this hook fee. Do not mix the two.

How the hook is implemented is a contract fact. This page is the design: V4, full-range hook, static 0 LP fee, 0 on buys / 1% HOLI burn on sells, and no developer cut. A <Md expr="w" /> vote admits names; it does not retune the exit tax.
