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.
