Extended Reviews
Perpetual DEX on Starknet built by a team with Revolut roots: 0% maker fees, cross-asset collateral and very low network costs.
Extended Rating
Our Opinion
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.
