Extended fees & measured trading cost

DEXEarn Extended Points

Extended runs a live order book on-chain, so its advertised fee is only the opening bid — spread and depth decide the real price of a fill. FeeFloor measures Extended's futures market on BTC, ETH, SOL and XRP, currently $25.79 all-in for $100K BTC futures, ranked against every venue we track. We count only what a market order pays to execute — funding, withdrawals and gas are measured separately.

What our measurements show

Extended's rank moves with trade size: #3 of 49 at $100K, but #37 at $10M. Fees are flat — depth is not.

At $100K, Extended executes 50% cheaper than the median venue we track (2.58 bps vs 5.20 bps).

The cost here is fee-dominated: 2.50 bps of the 2.58 bps total at $100K is the venue's own fee, over a book tight enough that spread and slippage barely register.

At $10M the book genuinely runs out — the venue can't fill that size within 2% of mid, so treat it as a smaller-order venue.

Patient traders do better here: resting maker orders pay 0.00 bps in fees against the 2.50 bps taker rate — $25.00 back on every $100K filled passively.

Cost by trade size

Fees are flat, but spread and slippage scale with size — so a venue that wins at $10K can be mid-pack at $10M. BTC futures, taker.

Extended: quick answers

What does a $100K BTC trade actually cost on Extended?

As of 2 August 2026, a $100K BTC futures market order on Extended costs $25.79 all-in (2.58 bps): 2.50 bps fee, 0.08 bps spread and 0.00 bps slippage. That ranks #3 of 49 venues we measure.

Is Extended better for small or large orders?

Right now, small orders: Extended ranks #4 at $10K and #37 at $10M. Fees are flat percentages, but slippage grows with size, so the answer shifts with the venue's live order-book depth.

Does Extended have hidden costs beyond the trading fee?

Yes — every order-book venue does. On top of the 2.50 bps list fee you pay the live spread (0.08 bps right now) and slippage that grows with order size (0.00 bps at $100K). Neither appears on the fee page, which is exactly why we measure them.
