Collateral Is Single-Use
You deposit. You borrow. You redeposit what you borrowed. You borrow again. The chain repeats until your “borrow power” looks enormous.
On paper, each step is valid. The collateral is still there—until it isn’t.
Everything looks fine. It isn’t.
The Illusion
Borrow power is a tidy label. It hides a dependency: the same economic stake is backing more than one claim.
Once collateral is redeposited and borrowed against again, positions are not independent. They stack. That is recursion—same base, layered claims.
Why It Breaks
- Price movement — A small move hits every layer built on the same collateral.
- Liquidity collapse — Forced sales meet thin books; marks and exits get worse together.
- Correlated unwinds — Everyone unwinds the same structure at once; the loop unwinds as a system, not as isolated loans.
The Default Behavior
Many lending systems let you borrow repeatedly against the same economic asset as you loop.
If you can loop your own collateral, it’s being counted more than once.

Why Not
MakerDAO
Keeps collateral and debt separate. You cannot reuse the borrowed asset inside the same vault in a way that re-leverages the same stake through that loop.
Maple Finance
Reputation and creditworthiness drive the loan. Deals are underwritten, not built from reusable collateral accounting. In practice you don’t get the same loop; the constraint is product and process, not the same ledger trick as a pure collateral market.
DorkFi
Collateral is removed at borrow time. Reuse is blocked in the accounting itself.
A Different Model
No abstract “borrow power” that survives after the collateral is spent. Collateral is subtracted when it backs a loan.
effective = max(0, total - excluded)Collateral used is removed.
Tradeoffs
Costs
Lower leverage. Lower capital efficiency. TVL that isn’t pumped by nested claims.
Gains
Risk that matches what is actually at stake. No recursive exposure. Simpler, flatter system state.
Closing
Some systems manage the loop.
This one removes it.
Collateral used is collateral removed.
