Extended review
The cheapest taker fee in the series at 0.025%, on a venue built by an ex-Revolut team that settles entirely on Starknet. Deposits are accepted from six EVM chains in USDC, ETH, USDT or wBTC, which removes the usual bridging detour.

Perpetual futures are leveraged: a small move against you can liquidate your position. Only trade what you can afford to lose.

You want to trade on a phone, or you need a referral program that pays in cash rather than points.
Strengths / Limits
Strengths
- 0.025% taker and 0% maker, the lowest taker fee of the whole series, with RWA markets at 0.010%.
- Funds stay in on-chain Starknet contracts, and the team says it has no custodial access; the contracts are published and audited.
- Deposits accepted from Ethereum, Arbitrum, Base, Polygon, Avalanche and BNB Chain, in four assets.
- $7.3B of perp volume over 30 days with normalized data matching reported data within 2%.
Limits
- The referral program pays 2.5% of points, not a share of cash fees: monetisation depends on what the points turn into.
- 100+ markets is an advertised floor, not a published count, and no mobile app is documented.
- Access is restricted by jurisdiction and the docs repeat eligibility caveats on every page.

How to start safely
- Open the official app
Type app.extended.exchange yourself or use a bookmark: phishing copies of perp exchanges are common.
- Deposit a small amount first
Send a test deposit of the collateral the exchange accepts, on the chain it documents, before moving more.
- Set leverage and a stop before the order
Pick isolated margin for a new trade, keep leverage low, and place the stop-loss with the order, not after.
- Watch funding and liquidation price
Funding is paid regularly while a position is open, and the liquidation price moves closer as leverage rises.
