Money taken and money waiting
Borrowed money is already with borrowers. Available money is supplied but has not been borrowed.
The useful read: Aave V3 is the largest borrower-facing system in this group, but size alone does not tell us whether its loans are safe or its lenders can leave quickly.
Does the market disappear without its leader?
No. Removing Aave V3 cuts the total sharply, but more than half of tracked borrowing remains.
The top three still carry 73.6%. The market is broad enough to survive a one-system removal test, yet concentrated enough that the leaders still matter.
What keeps a secured loan standing
The name on the app is only the front door. The money, protection and exit sit underneath it.
A lender supplies money
A saver, company or managed pool puts money where borrowers can take it.
The borrower locks more value
The borrower posts an asset worth more than the loan. That extra value is the first protection.
A price is watched
The system checks whether the locked asset still covers the debt.
The asset may be sold
If the safety margin breaks, the locked asset can be sold to repay the lender.
One contract, under a magnifying glass
Morpho is useful here because its market-level fields cover Ethereum and Base. This one example does not stand for the whole credit market.

How the loss path works: if the loan crosses this contract's maximum loan-versus-collateral rule, the position can be sold. The field does not promise that the sale will cover every dollar.
Issued is not the same as borrowed
$53.2bn of non-stablecoin tokenized assets are tracked across the wider market. This tells us what exists onchain, not how much protects a loan.
The useful limit: issuance proves an asset exists. It does not prove a borrower used it, a lender accepted it, or a loan was made against it.
Where the trouble lands first
These are separate failure paths. They should not be squeezed into one risk score.
The locked asset falls slowly
It can be sold before the loan becomes too large.
Borrower loses the locked asset. Lender is repaid first.The price falls too fast
The sale may bring back less money than the borrower owes.
The lender, reserve or insurer may carry the shortfall.The price check is wrong
A borrower may be sold too early, or a weak loan may remain open too long.
Loss depends on which error occurred.The contract itself fails
Collateral rules may work as written and users can still lose money through faulty code or control.
The affected users carry the loss unless protection exists elsewhere.Read any loan with four questions
Ignore the product name at first. If one answer is missing, that is where the review begins.
Who supplies the money?
Name the depositors, treasury or managed pool, not only the app shown to customers.
What protects the loan?
Name the locked asset, the price check and the point at which it can be sold.
How can money leave?
Can lenders withdraw now, must they wait for repayment, or do they need another buyer?
Who carries a loss?
Name the party left short if the asset falls too fast, the price is wrong or the contract fails.
