The five areas head to head
AI AnalysisFees & Costs
Fees run around 0.01% for makers and 0.05% for takers, tiered by trading volume, plus very low network fees on the native Cosmos chain. Against the fee-free newcomers in the segment that is no longer competitive; against centralised exchanges it remains inexpensive. As of August 2026.
Makers pay no trading fee, takers 0.025%. Depending on 30-day maker share, daily rebates of up to 2 basis points apply on top. Network fees on Starknet typically run to a few cents per transaction and barely register against the trading fee. As of August 2026.
Usability & User Experience

Extended runs more than 50 perpetual pairs and adds spot and lending markets. Collateral can be deployed across asset classes and margin is unified at account level. Alongside standard order types there are TP/SL brackets that set target and stop together. As of August 2026.

Verdict
Both providers are practically level in our overall rating (4.3 to 4.4).
dYdX set the standard in decentralised derivatives for years and made the most consistent architectural move in the sector with version 4: away from Ethereum, onto a purpose-built Cosmos chain where validators run the order book themselves. Matching, not just settlement, is decentralised — something most competitors still do not offer.
Market position has shifted drastically. From clear leadership in 2023, dYdX has fallen to a low single-digit share of perpetual volume while Hyperliquid and newer order-book DEXs absorbed the liquidity. For traders that mainly means thinner books in secondary markets and more noticeable slippage than at the volume leaders.
Technically the platform remains solid and fees of around 0.01% maker and 0.05% taker are reasonable. Traders who weight decentralisation highly find the most consistent implementation here; those chasing tight spreads are better served elsewhere. The platform holds no EU authorisation; perpetuals sit outside MiCA in any case, and tax reporting rests entirely with the user.
Extended was built by a team with a Revolut background and runs on Starknet mainnet. The product promise goes beyond plain perpetuals: collateral can be used across asset classes, margin is unified, and spot and lending markets round out the offering.
On price Extended leads: makers pay nothing, takers 0.025%, with daily maker rebates depending on maker share. Network fees on Starknet run to a few cents per transaction, so total costs stay low even for frequent trading.
Scale needs stating plainly: measured by capital locked, Extended is far smaller than Hyperliquid or Lighter, and the market list covers roughly 50 pairs. The platform holds no EU authorisation; perpetuals sit outside MiCA in any case, and tax reporting rests entirely with the user.
