Our take
Both are order-book perps venues from the Starknet ecosystem where you keep custody and withdraw with your own keys. Paradex charges nothing on orders placed through its web interface; Extended charges every user 0.025% taker and 0% maker, with no retail speed bump. Extended moved settlement from Starknet to Circle's Arc on 22 October 2026, while Paradex runs its own Starknet-based appchain. Both bar the US and Canada, and Extended also bars the UK.
Choose Extended if
You want stock, FX, commodity and index perps alongside crypto in one USDC account, a 10% fee discount through a referral code, or execution without a 300ms retail speed bump.
Choose Paradex if
You place orders by hand in the web interface and want zero trading fees, dated options in the same margin account, or you live in the UK, which Paradex's restricted list does not name.
Key differences
- Fees: Paradex Retail orders (web UI) pay 0% maker and 0% taker; its API (Pro) orders pay 0.045% taker and 0.003% maker. Extended is 0.025% taker and 0% maker for everyone, and 0.010% taker on RWA markets.
- Worked example, $10,000 position opened and closed with market orders: $0 on Paradex through the web UI, about $5.00 on Extended, and about $9.00 on Paradex through the API at the base tier.
- Settlement: Extended validates trades and health checks on Arc, Circle's Layer 1, since 22 October 2026, with USDC as native collateral. Paradex settles on the Paradex Chain, a Starknet-stack appchain that hides positions and PnL from the public.
- Products: Extended lists 300+ markets including stocks, FX, commodities, indices and pre-IPO perps. Paradex lists 90+ perps, spot and dated options markets.
- Referrals: an Extended code takes 10% off fees for the first $50M of volume. A Paradex code gives a 5% XP (points) bonus, not a fee cut.
- Geo: both bar the US and Canada. Extended's list also names the UK, Hong Kong, Panama and Seychelles; Paradex's list does not name the UK.
- Track record: a Paradex database migration error on 19 January 2026 priced BTC at $0 and forced a chain rollback after about eight hours offline. Extended's CEO said a partial-liquidation bug caused about an hour of downtime after the October 2025 crash.
