Margin System
Overview of Backpack’s Margin System
Backpack’s margin system is designed to be simple and resilient. At a high level you:
keep one pool of collateral,
earn yield on idle balances,
borrow automatically when you need to,
and isolate risk with sub-accounts.
For full technical details, see the Margin docs
Unified cross-margin. Your eligible assets (spot balances, perps margin, lending balances) live in one collateral pool, so you don’t have to shuffle funds between products.
Sub-accounts for risk isolation. Create independent sub-accounts. Each has its own collateral, PnL, and margin—so a mistake in one doesn’t spill into another.
Fewer transfers, more utility. Because funds are pooled, you can deploy capital quickly without moving assets around.
Important Update (Effective October 6, 2025 — 07:00 UTC)
We’re introducing a liquidation fee.
Rate: 1% on all system-triggered perps and borrow/spot-margin liquidations.
Scope: Applied only to the filled amount of each liquidation order (per fill).
Unchanged: Regular user trades and fees are unaffected.
