We funded a Hyperliquid account, ran perpetuals through the order book, and checked its fee schedule against a centralized exchange. Here is where the speed holds up and where the JELLY incident still matters.
We opened a Hyperliquid account, connected a wallet, funded it with USDC and placed a run of perpetual orders on BTC and HYPE to answer one question: does an on-chain order book actually feel like a centralized one, or is that just marketing.
The order book felt like a centralized exchange
Order placement returned in well under a second in our tests, and the book stayed liquid on both BTC and the smaller HYPE-USDC pair we watched during a volatile afternoon. Hyperliquid runs its own Layer 1, HyperBFT, which the team states reaches roughly 0.07-second blocks and a theoretical throughput near 200,000 transactions per second. We cannot verify the ceiling, but nothing we did hit a visible queue.
What matters more than raw speed is that the funds never left our wallet. There is no deposit sitting in an exchange-controlled account and no withdrawal queue to join if the operator has a bad week. That single design choice removes an entire category of risk that has hurt centralized futures traders before.
What the fees actually cost
Hyperliquid's base perpetual fees sit at 0.045% for takers and 0.015% for makers, before any volume or HYPE-staking discount, according to the fee schedule Hyperliquid Labs publishes and third-party trackers confirm. Both rates undercut most centralized derivatives desks at the entry tier, and heavy makers can reach a rebate rather than a fee once volume climbs. Ninety-nine percent of protocol revenue routes to an Assistance Fund that buys HYPE on the open market, a mechanic no centralized exchange offers because the fee revenue there belongs to shareholders, not the token.
