Earning

Leverage has to come from somewhere. If you supply it, you are paid for it — and you carry the risk that comes with it.

Fund the longs

Supplying USDT

Every leveraged long borrows USDT. That USDT comes from suppliers, and they earn the interest borrowers pay. The rate is set by utilisation: the more of the pool is lent out, the more it costs to borrow and the more suppliers earn.

Two ways to supply

Insured or Raw

Bad debt has to land on someone. You choose whether that is you.

TierYou earnOn a default
Insuredabout 70% of the yielda reserve absorbs the loss before you do
Rawthe full yieldyou take the write-down first

The 30% the Insured tier gives up is what funds the reserve standing behind it. Neither tier is a guarantee: a large enough loss reaches both.

Fund the shorts

Lending the token itself

Shorts borrow the token, so a holder can lend theirs and earn interest in the token instead of leaving it idle. This is the only way shorts exist on a market — until somebody supplies, there is nothing to borrow and the market is long-only.

You are taking the other side of the short
Your tokens are sold into the pool the moment they are borrowed. You are owed the same number back, not the same value — so if the price collapses and the borrower cannot repay, what you recover is worth less than what you lent.
Be clear about this

What a supplier actually risks

Interest is paid for taking a risk, and the risk is that a position goes bad faster than it can be closed. Liquidation is meant to happen before that, but a collapse steep enough to outrun it leaves debt with nothing behind it.

When that happens the loss is paid in order: the liquidation penalties collected on the way down, then the token’s insurance account, then the Raw tier, then the Insured tier. Every step is visible on chain — a loss is written down, not hidden in a number that stops updating.

Your withdrawal depends on utilisation
Supplied USDT that is currently lent out cannot be withdrawn until it is repaid or liquidated. A pool at high utilisation pays well precisely because that money is working; if you need it back immediately, you may have to wait for a borrower.
