# What is Uptober Fest?

Uptober Fest: zero trading fees on ETH and BTC perps, with current trading points program ending October 31.

## Key highlights

* **Zero fees on ETH/BTC perps**: 0% maker and taker fees across web, mobile, webhooks, and API
* **Same execution quality**: Same deep liquidity and speed; this is not “low fees, high slippage”
* **Other markets unchanged**: All other markets retain existing fees (for now)
* **Duration**: One‑month, ending **October 31**

## How do LPs earn without trading fees?

Interest Rate Module: utilization-based interest replaces trading fees when OI is high

* **New Interest Rate Module**: When open interest utilization gets high, traders pay a small interest rate instead of trading fees
* **LP earnings mix**: Liquidity providers earn from spreads, funding rates, and the new utilization‑based interest mechanism
* **Goal**: Sustainable yield for LPs while delivering zero fees to traders on eligible markets

## What happens after the fest?

If the fest is successful and volume meaningfully increases, we plan to expand zero‑fee trading to more markets beyond ETH and BTC.
