DeFi lending, explained.A pool, a curve, a liquidator.
DeFi lending protocols let anyone supply tokens to a pool and earn interest from borrowers. There is no loan officer. Rates move with demand, borrowers post collateral, and code sells that collateral if a loan becomes unsafe.

The short answer
Lenders supply tokens to a pool and receive a deposit token. Borrowers lock collateral and take loans from the same pool.
Interest rates follow utilization: the more of the pool is borrowed, the higher the rate for both borrowers and suppliers.
If a borrower’s collateral falls in value, anyone can liquidate the position by repaying part of the debt and taking collateral at a discount.
If liquidation fails to cover the debt, the pool has bad debt. Depending on the design, lenders may share that loss.

How a lending market works
Aave, Morpho, Kamino and similar protocols follow the same basic logic.
- 1
Supply
You deposit a token such as USDC into a market. You receive a token that tracks your share and grows as interest accrues.
- 2
Borrow
A borrower deposits collateral, often ETH, BTC or a staked token, and borrows against it up to a set loan-to-value limit.
- 3
Utilization
Utilization is borrowed amount divided by supplied amount. It is the main driver of the rate.
- 4
The rate curve
Rates rise slowly at low utilization and steeply above a target level. This pulls in new supply and pushes out borrowers when the pool gets tight.
- 5
Supply rate vs borrow rate
Suppliers earn the borrow rate times utilization, minus a reserve factor kept by the protocol. That is why supply rates are always lower than borrow rates.
- 6
Pooled vs isolated markets
Aave uses large shared pools. Morpho and some Kamino markets use isolated markets or vaults run by curators, where each market has its own collateral and risk settings.
Liquidation, bad debt and what to check
The risks for lenders sit mostly in what happens when borrowers fail.
- 1
Liquidation
When a loan crosses its liquidation threshold, liquidators repay debt and receive collateral plus a bonus. This normally keeps the pool whole.
- 2
Bad debt
If collateral drops too fast, or its market is too thin, liquidation may not recover the full loan. The shortfall is bad debt.
- 3
Who absorbs losses
Some protocols have a safety module or reserve. In isolated markets, losses typically fall on that market’s lenders. Read how the protocol handles shortfalls.
- 4
Oracles
Prices come from oracles. A wrong or manipulated price can trigger unfair liquidations or let bad loans through.
- 5
Withdrawal at high utilization
If nearly all supply is borrowed, there may be little left to withdraw. You wait until borrowers repay or new supply arrives.
- 6
Rewards vs base rate
Displayed rates often include token incentives on top of interest. Those can end at any time. Check the base rate separately.

Questions
How do DeFi lending rates work?+
They are set by an interest rate curve based on utilization. When more of the pool is borrowed, rates go up; when demand falls, they go down.
Can I lose money lending on Aave or Morpho?+
Yes. Smart contract bugs, oracle failures and bad debt from failed liquidations can cause losses. A stablecoin you lend can also lose its peg.
Why can’t I withdraw my deposit?+
Usually because utilization is near the maximum. Your funds are lent out, and withdrawal depends on repayments or new deposits.
What is the difference between Aave and Morpho?+
Aave runs large shared pools with governance-set parameters. Morpho runs isolated markets and vaults where curators choose which markets to lend into.
