Fees

Builder fee approval, in depth

The second signature in onboarding is the one people skim, which is unfortunate, because it is the entire commercial relationship. It sets a ceiling on what can be charged, and it is enforced by the exchange rather than by an invoice.

In short

The builder-fee approval authorises a maximum fee rate that a builder may add to orders it routes for your account. HyperMirror charges 0.1% of mirrored notional volume through that native mechanism. It is not a deposit, not a subscription, and not a share of your profits — and because the ceiling is what you signed, it cannot be raised without a new approval from you.

What the approval authorises

Hyperliquid supports a builder fee: a rate attached to orders submitted by an approved builder on your behalf. You approve a maximum rate once, and any order routed for you can carry a fee up to that ceiling.

That is the whole mechanism. There is no separate billing relationship, no card on file, and no balance held by the platform.

It sets a maximum rate, not a fixed charge.
It applies only to orders routed for your account by the builder.
It cannot move funds, cannot withdraw, and is unrelated to the trading agent's scope.
It is revocable from your wallet, like the agent approval.

What 0.1% of mirrored notional means in practice

The fee is charged on the notional volume that is mirrored into your account, not on your equity and not on your gains. Turnover therefore drives cost: a high-frequency leader generates more mirrored volume for the same capital than a slow swing leader does.

This is worth understanding before you compare it with a performance fee. A profit share costs nothing in a flat month and a great deal in a strong one; a volume fee is proportional to activity in either direction.

Why a volume fee rather than a profit share

A performance fee creates an incentive to chase volatility, because upside is shared and downside is not. A flat volume fee keeps the incentive aligned with running the basket as designed rather than with maximising variance.

It is also the only revenue line. There is no subscription tier, no spread markup and no order-flow arrangement layered on top.

The costs the builder fee is not

Hyperliquid's own taker and maker fees still apply, as does funding on perpetual positions. Those are exchange-level costs that exist whether or not you mirror anyone, and they are separate from the builder fee.

Past performance is not indicative of future results. Perpetual futures are leveraged instruments and carry a substantial risk of loss, including the loss of your entire position.

Methodology

Scoring and replacement are documented in full on How it works and in the Docs (Policy v3). In short: the Elite basket is sticky, emergencies remove a leader immediately, and soft issues accrue at most one strike per UTC day with three strike-days triggering replacement. Read how it works or the documentation for the full table.

Questions

Frequently asked

Can the fee be raised without me noticing?

No. The rate you approve is a ceiling enforced by Hyperliquid. Raising it would require a new approval signed by your wallet.

Is there a performance fee?

No. The 0.1% builder fee on mirrored notional volume is the only revenue HyperMirror takes.

Do I pay when nothing is mirrored?

No. The fee applies to mirrored volume, so a paused account with no mirrored orders generates none.

Does the fee include Hyperliquid's own trading fees?

No. Exchange taker and maker fees and perpetual funding are separate exchange-level costs.
