Aave Collateral Swap: Change Your Collateral
Rebalance your active collateral backing on Aave v3 without repaying existing debt obligations or closing your position.
How Aave Collateral Swap Works
Replace underlying collateral backing without closing debt or repaying loans
Select Current & Target Collateral
Choose the asset currently backing your loan (e.g. ETH, WBTC, wstETH) and select the desired collateral token to replace it.
Flash Loan Collateral Replacement
DashsWallet executes a flash loan to deposit the target collateral, releases the original collateral, swaps it via DEX liquidity, and settles the flash loan.
Monitored Health Factor Target
Verify that your new collateral maintains a safe Health Factor threshold and enjoys updated supply APY rates.

Frequently Asked Questions
Q1.What is an Aave Collateral Swap?
An Aave Collateral Swap is an atomic operation that switches the underlying token backing your debt on Aave v3 (for example, swapping supplied ETH for WBTC or USDC) while leaving your borrowed liabilities active.
Q2.Why swap collateral on Aave v3?
Traders and yield farmers swap collateral to take profit, migrate into higher-yielding assets (like liquid staking tokens), or hedge against price volatility by shifting into stablecoins during downturns.
Q3.How does DashsWallet surplus-sharing work on collateral swaps?
When market execution produces more tokens than your minimum accepted amount (positive slippage / surplus), DashsWallet shares the excess: the protocol retention is capped at 2.5% maximum, and 50% to over 75% of the surplus is automatically credited back to your collateral deposit as cashback.
Q4.How does this compare to swapping on the official Aave web interface?
The official Aave web interface routes collateral swaps through CoW Swap with partnerFee settings that charge 15 to 25 bps on the full transaction volume. DashsWallet charges 0 bps on the principal and only retains a capped portion of positive market surplus. See the full breakdown on our surplus-sharing architecture page.
Q5.Is DashsWallet the only protocol offering this surplus-sharing model?
As far as our research has found, we have not identified another public protocol that combines an atomic Aave v3 flashloan collateral swap with surplus cashback returned to the user. This is based on our own review, not an exhaustive market audit.
Q6.How does collateral LTV impact the swap?
Different collateral assets have different Loan-to-Value (LTV) ratios and Liquidation Thresholds on Aave v3. Swapping to an asset with a lower LTV may lower your Health Factor. DashsWallet calculates and displays the exact post-swap Health Factor upfront.
Q7.Do I need to repay my debt before swapping collateral?
No. DashsWallet uses flash loans to temporarily supply the new collateral before withdrawing the old asset, enabling the swap without needing to repay existing debt.
Q8.Is there any downtime during a collateral swap?
No. The transaction is atomic, executing entirely within a single EVM block. Your position is never left uncollateralized or vulnerable to market shifts during execution.
