Extended is a perpetual-futures DEX on Starknet with hourly funding and a 2 bps maker / 4 bps taker schedule. It is another pre-TGE venue in the active-points cluster, and its hourly cadence makes it a natural counter-leg to the 8-hour Starknet sibling Paradex or to a CEX.
What is Extended?
Two Starknet venues with different funding cadences (Extended hourly vs Paradex 8-hour) frequently drift apart on the same asset — a clean, same-ecosystem cross-exchange spread to capture delta-neutral while farming Extended's points.
Extended points & airdrop
Extended is pre-TGE and running an active points program; trading volume accrues points expected to convert into a future airdrop. Its fees are a touch higher than the zero-fee venues, so the funding spread has a little more to overcome — the backtester nets it out.
Hold the Extended leg of a hedged pair and farm points on capital you are committing for the funding spread anyway. Use the ORBIT Points Calculator for an FDV-based dollar estimate before choosing it over a cheaper points leg.
Extended trading fees
Extended charges 4 bps taker and 2 bps maker on perpetuals. On a round-trip — entry and exit, and across two venues if you trade delta-neutral — those fees are the first thing any spread has to overcome. ORBIT's backtester subtracts both legs' taker fees plus live order-book slippage, so the PnL it shows is net, not headline.
Funding rates on Extended
Extended settles funding every 1h. Funding is the payment between longs and shorts that anchors the perpetual to spot — and because every venue computes its own rate, the same asset can pay very differently on Extended than on another exchange at the same moment. That gap is a tradeable, delta-neutral edge.
Is Extended safe?
Extended is non-custodial on Starknet, with the usual young-venue considerations: smart-contract risk and variable long-tail liquidity. Directional risk is removed by the delta-neutral structure; the live risk is a per-leg move before you rebalance.
Because its taker fee is higher than the zero-fee venues, prioritize majors with a wide enough spread that 4 bps round-trip does not erase the edge — the backtester will tell you immediately.
How to get started with Extended
- Open Extended and connect your wallet.
- Deposit margin (USDC on Starknet) and start with a small size while you learn the interface.
- Open the Funding Screener to see where Extended's funding diverges from another venue.
- Confirm the net edge in the backtester — it subtracts fees and slippage — before sizing up.
Extended vs Paradex
The most common comparison for Extended is Paradex. Rather than restate fees here, see the live side-by-side — funding, fees, open interest and airdrop status — on the Extended vs Paradex comparison. For funding arbitrage you often use both: long the lower-funding venue, short the higher one.
Extended review: verdict
Extended is a decent pre-TGE points leg, most interesting as the hourly-funding counterpart to Paradex within the Starknet ecosystem. Its fees are slightly higher than zero-fee venues, so favor wider spreads on majors — but for farming points on a hedged Starknet pair it earns a place in the rotation. Verify net PnL in the backtester.
