2. Click “Diamond Proxy” > “Read”
3. In the left sidebar, click “ViewerFacet”

ViewerFacet selected in sidebar — scroll down to find positions and restakers functions:

​

Check Restake Position

Find and expand the restakers function. Click Query. You will see: Example: querying the aEthWETH/WETH restake pool (0xc95d...6459) for address 0x08c7...bff5 — result shows scaledSupply and interest:

Note: scaledSupply is RAY-scaled (divided by 10^27 with the liquidity index). The actual amount is approximately scaledSupply * liquidityIndex / 10^27.

​

After Unstaking: Withdraw from Aave

After unstaking, you receive the aToken (e.g. aEthUSDC, aSonUSDC, aPlaUSDT0). To get the underlying token (e.g. USDC), withdraw via the Aave UI: app.aave.com — Go to Dashboard > find your supplied asset > click Withdraw > enter max amount > confirm.

​

3.5. Redeem re-aUSDC (Sonic Only)

If you hold re-aUSDC on Sonic, you need to redeem it to get back your aSonUSDC (aToken). re-aUSDC Contract: 0x561d1907dd7C0B92E5278356BC230B7e94704d57 re-aUSDC is an ERC4626 vault. Use withdraw to get back an exact amount of aSonUSDC.

​

Step by Step

4. Repay Debt

If you have an outstanding borrow position, you must repay the debt before withdrawing collateral.

​

How much debt do I owe?

Your debt amount can be calculated from on-chain data:

1. Go to Diamond246 > “Diamond Proxy” > “Read”
2. Call positions with your pairId + wallet address — note your debtShares
3. Call pairs with the same pairId — note totalDebtShares and totalScaledDebt

Your debt ≈ (debtShares × totalScaledDebt) / totalDebtShares

Note: This gives you an approximate amount in the token’s smallest unit (e.g. 6 decimals for USDC, so 100000000 = 100 USDC). The actual debt accrues interest over time, so approve a bit more than this estimate (e.g. add 1%). The repay function only transfers the exact amount owed — any excess stays in your wallet.

​

Step 1: Approve Diamond246

Before repaying, you need to approve Diamond246 to spend your debt token.

Tip: Don’t approve max uint256 if you’re uncomfortable with unlimited approvals. Instead, approve an amount slightly above your estimated debt. The repay function only transfers the exact amount owed — any excess approval is not spent.

1. Go to the debt token contract on the block explorer (links below)
2. Click “Write as Proxy” (for proxy tokens like USDC) or “Write Contract”
3. Click “Connect to Web3”
4. Find the approve function
5. Fill in:

6. Click Write and confirm
7. (Optional) After repaying, you can revoke the approval by calling approve again with amount 0

Example: approving USDC on Etherscan — approve expanded with Diamond246 as spender and 100 USDC (100000000) as value:

Step 2: Repay on Diamond246

1. Go to Diamond246 > “Diamond Proxy” > “Write”
2. In the left sidebar, click “BorrowingFacet”
3. Find and expand the repay function
4. Fill in:

5. Click Write and confirm

Example: repaying on the hyperUSDC/GHO pair — BorrowingFacet selected, repay expanded with GHO as debt (0x40d1...6c2f), hyperUSDC as collateral (0x7777...7777), amount=0 and share=max for full repay:

​

5. Withdraw Collateral

After repaying all debt, you can withdraw your collateral.

Important: You must repay all debt first. If you have outstanding debt, this transaction will revert.

1. Go to Diamond246 > “Diamond Proxy” > “Write”
2. In the left sidebar, click “CollateralManagementFacet”
3. Find and expand the withdrawCollateral function
4. Fill in:

5. Click Write and confirm

Example: withdrawing collateral from the hyperUSDC/GHO pair — CollateralManagementFacet selected, withdrawCollateral expanded with GHO as debt, hyperUSDC as collateral, exact collateral amount entered:

Important: For amount, use the exact collateral value returned by the positions read call in step 2. Do NOT use max uint256 — it will revert.
