Hyperliquid Backstop Liquidation and HLP Explained
How Hyperliquid liquidations work step by step: partial liquidation, order-book execution, and the backstop transfer to HLP's liquidator.
Direct answer
Hyperliquid first tries to liquidate an underwater position through the order book, sometimes partially. If an account falls below two-thirds of maintenance margin without a successful book liquidation, a backstop transfer can send the position to HLP's liquidator component. You can lose your position before a stop fills, and HLP takes on the risk.
In short
- 1Liquidations can be partial and are tried through the book first.
- 2The backstop threshold is two-thirds of maintenance margin.
- 3HLP's liquidator component can absorb positions, which is part of HLP's risk.
What is the liquidation flow?
When margin falls to the maintenance requirement, the system tries to reduce the position through the order book. Hyperliquid may use partial liquidations, closing enough to restore the account rather than all of it, where the rules allow.
What is a backstop liquidation?
If book liquidation fails and the account drops below two-thirds of maintenance margin, the position can be transferred to HLP's liquidator component. This is a last resort that protects the system from bad debt.
Why does HLP matter here?
HLP is community-owned and runs market-making and liquidation strategies. Taking over liquidated positions can produce profit or loss, and that exposure is shared by depositors. It is one reason HLP returns are not a fixed yield.
What should traders take from this?
A stop order is not a guarantee against liquidation. In a fast move the margin boundary can be reached first. Keep enough buffer that your stop sits well before it, and read the liquidation guide for the tier-aware formula.
Example: a gap through the boundary
Say a long is liquidatable at $2,000 but the price gaps from $2,030 to $1,950 in seconds, and the book cannot absorb the position. If equity is already below two-thirds of maintenance, the position can transfer to HLP's liquidator component.
The trader loses the position at the system's price rather than their stop, which might have sat at $1,990. This is a simplified example of why gaps matter more than stop distance.
Common mistakes
Keep the stop well inside liquidation and use lower leverage in thin books.
- Believing a stop guarantees an exit above liquidation.
- Running high leverage in thin markets where gaps are likely.
- Treating HLP as risk-free because the protocol owns it.
Practical next steps
The practical lesson is to design for the gap, not the average move. Pick leverage so that your stop sits comfortably inside the estimated liquidation price, then check the visible depth at the levels between them. In a thin market, assume the exit can fill well beyond your stop and keep enough margin to absorb that. If you deposit in HLP, remember that you are sharing the other side of these events, and read the HLP risk page for live figures before putting money in.
