Your supplied balance in Aave is not necessarily the amount you can withdraw immediately. A withdrawal needs enough unborrowed liquidity in the pool. If those tokens also support an active loan, removing them can create a separate collateral problem, even when the pool has liquidity available.

| Aave withdrawals require sufficient liquidity that is not currently borrowed from the pool. |
| Supplied tokens used as collateral may require loan repayment or additional collateral before withdrawal. |
| A health factor below 1 signals liquidation risk; removing collateral deserves particular care. |
| Withdrawing the same underlying token differs from withdrawing and switching into another token. |
Check which limit is holding up the withdrawal
The official withdrawal guide says suppliers can withdraw up to the amount available in the pool that is not currently borrowed. That limit concerns the pool, rather than just the balance displayed for your account. A large supplied balance therefore does not, by itself, establish that the same quantity is available to leave the protocol now.
The second check concerns your own position. Aave says that if supplied tokens are being used as collateral, you may need to repay part of the borrowing or supply additional collateral before withdrawing. Adding collateral addresses that account constraint; it does not establish that the pool has enough unborrowed tokens for your intended withdrawal. Treating those as separate questions avoids mistaking one remedy for a solution to both.
Aave’s collateral-status explanation describes the health factor as an indicator of the position’s collateral coverage. A value below 1 signals liquidation risk. The page also distinguishes loan-to-value, which limits opening a new borrowing position, from the liquidation threshold. Do not substitute a borrowing limit for a check of the withdrawal’s effect on existing collateral.
Read the transaction you are actually approving
In the interface, the documented route is Dashboard, Your Supplies, then the chosen token and withdrawal amount. Check the available liquidity and whether the asset is supporting a loan before confirming. This is a guide to those checks, not evidence that a particular asset or market currently has enough liquidity.
The withdrawal method also matters. According to Aave, withdrawing the same underlying token, such as WETH to WETH, needs no additional approval transaction. Withdrawing a network’s base token such as ETH instead involves the WrappedTokenGateway, which unwraps the stored wrapped token. The interface’s separate withdraw-and-switch feature requires approvals for the withdrawal and switch.
Read those requests against the action you intended. An explanation that no extra approval is needed for a same-token withdrawal does not apply unchanged to switching tokens. Before confirming, establish both what leaves your supplied position and what arrives in your wallet; a successful interpretation of the approval screen cannot remove either the liquidity constraint or the collateral requirement.
