Hyperliquid vs Aster (2026): Fees, Custody, Which to Pick

Hyperliquid and Aster are both order-book perpetual DEXs that skip identity checks entirely — wallet-based self-custody, no KYC, no exchange holding your funds on your behalf. Where they genuinely diverge is architecture and, more consequentially for cost-conscious traders, the fee schedule: Aster's headline rates undercut Hyperliquid's by a wide margin. That's not a claim we're going to talk around just because Hyperliquid is the platform we cover in depth.

Fees

On paper this isn't close: Aster is cheaper to trade on. Hyperliquid's base perp rate is 0.045% taker / 0.015% maker, improving through volume tiers to 0.024% taker, plus a 5–40% discount for staking HYPE and a 4% discount on the first $25M of referred volume. See the full Hyperliquid fees breakdown for tier detail.

Aster runs two fee tracks by collateral, per its official docs: USDT-margined perpetuals cost 0% maker / 0.04% taker, and USD1-margined perpetuals cost 0% maker / 0.005% taker — well under a tenth of Hyperliquid's base taker rate. Paying in ASTER saves a further 5%, and Aster's referral program gives referred accounts up to a 10% fee rebate.

For a maker-heavy strategy, Aster's 0% maker rate on both contract types is a genuine advantage over Hyperliquid's 0.015% base maker fee. We're not going to manufacture a fee win for Hyperliquid here: on the numbers alone, Aster wins the fee comparison outright.

Architecture and custody

Hyperliquid runs its own purpose-built layer-1 blockchain; every order, cancellation, and fill is processed on-chain, not matched off-chain and merely settled there. Collateral is USDC, and withdrawals settle to Arbitrum for a flat $1 fee. Its Arbitrum bridge has a published audit from Zellic — a concrete reference point for assessing bridge risk rather than taking it on faith.

Aster is an order-book perpetual DEX built within the BNB Chain ecosystem. Like Hyperliquid, it's wallet-based and self-custodial — no exchange-controlled account, no identity check to trade. We don't have an independently verified audit report for Aster to set against Hyperliquid's Zellic review, so treat that as an open question rather than an assumed gap. On custody and KYC specifically, the two are functionally equivalent: neither asks who you are, and both leave funds under wallet control rather than platform control.

Where Aster wins

• Lower headline fees across the board. 0% maker on both USDT- and USD1-margined perpetuals beats Hyperliquid's 0.015% base maker fee outright.
• USD1-perps taker fee. At 0.005% taker, it undercuts Hyperliquid's 0.045% base rate and its best volume-tier rate of 0.024% alike.
• Token-based fee discount. Paying in ASTER shaves a further 5% off fees, stacking on top of the base rate.
• Referral rebate. Referred accounts get up to a 10% fee rebate, versus Hyperliquid's volume-capped referral discount.

Where Hyperliquid wins

• Liquidity depth. Public trading analytics consistently place Hyperliquid among the deepest order books of any perp DEX — depth that affects your fill price more than the posted rate does, especially at size.
• Broader ecosystem. Beyond perp trading, Hyperliquid supports permissionless vaults, its own EVM-compatible chain (HyperEVM), and equity perpetuals — none of it factors into the fee comparison, but it matters if you want more than a trading venue.
• Published bridge audit. The Zellic audit of Hyperliquid's Arbitrum bridge is a checkable reference point rather than an unverified claim.
• Longer track record. Hyperliquid has operated longer as a major on-chain perp venue — not a guarantee of anything going forward, but a real difference in history.

Which to pick

Fee-sensitive traders running a maker/limit-order strategy: Aster's 0% maker rate is hard to beat on cost alone, especially on USD1-margined pairs, where the taker fee also undercuts Hyperliquid.

Traders who care about fill quality, or who want vaults, HyperEVM, and equity perps: Hyperliquid's liquidity depth can matter more than a fee-rate difference at size — a cheaper rate on a worse fill isn't cheaper — and only Hyperliquid offers that broader product surface.

Anyone weighing bridge or custody risk specifically: Hyperliquid's published Zellic audit gives you something concrete to evaluate; we don't have an equivalent verified reference for Aster.

Neither answer is universal; plenty of traders reasonably use both for different purposes. See our broader best perp DEX comparison if you're weighing more than these two, and read our Hyperliquid overview before committing funds.

Can I trade on Hyperliquid or Aster from the US?
