Aave lets users supply crypto assets to a pool and borrow other supported assets against collateral. That does not make a DeFi loan “set and forget.” The key question is whether a price move or accrued interest can push the position into liquidation before you can respond.
What borrowing on Aave actually means
A borrow position is overcollateralized: the value supplied as collateral must stay high enough relative to the value borrowed. Each market and asset has its own risk parameters, including a loan-to-value limit and a liquidation threshold. Available assets, rates, and parameters can change by market, so the live interface and the protocol documentation are the places to verify them before signing.
Borrow interest begins to accrue after the transaction. A position can also become riskier when collateral falls, when the borrowed asset rises, or when a stablecoin trades away from its intended price. “I borrowed a stablecoin” is not the same as “my risk cannot change.”
Health factor: the number to watch
Aave expresses the safety of a position with a health factor. In simplified form, it is collateral value multiplied by its weighted liquidation threshold, divided by debt value. A health factor below 1 means the position is eligible for liquidation. It is an indicator, not a promise of safety: price feeds, debt, and collateral composition all matter.
For a simple illustration, supplying $10,000 of collateral with an 80% liquidation threshold and borrowing $6,000 produces a health factor near 1.33. If collateral falls or debt grows, that buffer shrinks. The example is educational only; it is not a recommended borrowing level.
What liquidation can cost
When the health factor falls below the threshold, any eligible liquidator can repay part of the debt and receive collateral plus the applicable liquidation incentive. You may keep some position, but you can lose collateral at a discount and emerge with less flexibility than before. The exact close factor and bonus depend on the market and the affected assets.
A pre-transaction checklist
- Confirm the network, the asset contract, and the current Aave market.
- Read the live loan-to-value and liquidation parameters for the collateral.
- Model a downside move and allow room for interest accrual and transaction delays.
- Keep a way to add collateral or repay without relying on a single congested bridge or exchange.
- Review the wallet prompt and retain native tokens for transaction fees.
Do not confuse a dashboard with risk management
A dashboard is useful only if you can act on it. Alerts, a written response plan, and modest sizing are more practical than trying to predict every market move. If you are also considering pool income, first understand how it differs from debt risk: read our guide to impermanent loss in liquidity pools.
