Sub-accounts

Sub-accounts and position isolation

Mirroring more than one trader sounds like a feature until you look at where the positions land. In a single account, two leaders holding opposite views on the same market silently cancel each other out — and you pay for both. Sub-accounts are the mechanism that stops that happening.

In short

A Hyperliquid sub-account is a separate account under your own ownership with its own margin and its own positions. HyperMirror mirrors one Hyperliquid sub-account per mirrored leader, so each leader's positions are held, margined and measured on their own. That preserves every leader's intent, keeps their performance attributable, and prevents one leader's book from being netted against another's.

Why isolation is a structural requirement, not a nicety

Copy trading a basket is portfolio construction: you are deliberately holding several strategies at once because their mistakes do not arrive on the same day. Netting undoes that on the way in — the exposures are combined before they can diversify anything.

Isolation is what makes a multi-leader basket behave like a basket instead of like an accidental single position with extra fees.

Each leader's long and short exposure survives intact.
Per-leader PnL is measurable, which is what makes scoring and replacement meaningful.
Margin problems in one sleeve cannot consume the margin backing another.
Replacing one leader touches one sub-account and leaves the rest untouched.

What isolation does not do

Isolation separates positions; it does not neutralise market risk. If every leader is long and the market falls, every sleeve loses. Correlation across leaders is a real limit on diversification, and it is why leader styles matter as much as leader count.

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.

Starter mode and Full mode

Starter mode mirrors one leader, so there is nothing to net. From $100,000 of mirrored volume, Full mode mirrors up to 10 leaders in parallel, each in its own sub-account, with capital weighted by score rather than split evenly.

The unlock is a practical threshold, not a paywall: splitting small capital across ten sleeves produces position sizes too small to track their leaders faithfully.

Comparison

Basic copy tools vs HyperMirror

The differences that change your risk profile, not the feature-list ones.

Dimension	Basic copy tools	HyperMirror
Where positions sit	One account; all copied positions share a book.	One isolated sub-account per mirrored leader.
Opposing views	Net against each other; both leaders' intent is lost.	Both positions are held as the leaders intended.
Attribution	Blended PnL — you cannot tell who worked.	Per-leader PnL, which is what scoring needs.
Margin	Shared; one bad sleeve pressures every position.	Separated per sleeve.

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.

Questions

Frequently asked

Are sub-accounts still mine?

Yes. Sub-accounts belong to your own Hyperliquid account. Funds never leave your ownership and withdrawals remain signable only by your wallet.

Do sub-accounts split my fee tier?

Volume across your sub-accounts aggregates for fee-tier purposes, so isolation is an accounting and risk decision rather than a fee penalty.

How many sub-accounts will I have?

One per mirrored leader — one in Starter mode, up to 10 in Full mode.
