Liquidation

What happens when a position can no longer cover what it owes, and who ends up paying.

The threshold

Health, and when it runs out

A position’s health is its equity divided by its exposure. Equity is simply what you hold minus what you owe, so it falls as the market moves against you. Below 4%, anyone may close the position.

The trigger uses an average, not the last trade
A single transaction cannot push the 10-second average, so nobody can flash-crash the price to liquidate you and buy your collateral cheaply. The cost is that in a genuine collapse the trigger lags slightly behind the market.
The mechanics

It sells into the same pool you traded

Closing a long sells the collateral; covering a short buys the token back. Both go through the ordinary pool, at the ordinary price, and print an ordinary candle — there is no separate liquidation venue and no privileged counterparty.

While a position is still solvent it is closed in parts, so a brief dip does not wipe out someone who would have recovered. Once equity has gone negative the loss is already real, and delaying only shrinks what lenders get back — so at that point the whole thing can be closed at once.

When it is not enough

Bad debt is written down, not hidden

If the collateral no longer covers the debt, the shortfall is recognised immediately: the token’s insurance account pays what it can, and whatever is left is deducted from suppliers’ claims — Raw tier first, then Insured.

Why write it down at all
A loan that will never be repaid still counts as lent-out money until someone says otherwise. Left alone it would misreport how much of the pool is in use, keep the interest rate wrong, and stop the last suppliers from ever withdrawing. Recognising it is worse news, sooner, for a smaller number of people.
Why anyone bothers

The liquidator is paid first

The 10% penalty comes off the top, before the debt is repaid. That ordering is deliberate: a position worth liquidating has, by definition, almost nothing spare, so a fee taken from what is left over would be zero exactly when the work matters most. An unliquidated position costs lenders far more than the fee does.
