# Manage your positions

Adjust, repay and merge your CDPs, and claim leftover collateral.

Your CDPs are on **Positions**, on the **Manage** tab. Each one has **Adjust** and **Repay** buttons, which also appear on the CDP's own page.

## Adjust

Adjusting a CDP changes its collateral, debt or rate cap, and pays the interest it has accrued so far.

1. Select **Adjust** on the CDP.
2. Change the collateral, debt or rate cap.
3. Check the updated debt, collateral and health factor, then select **Adjust Position**.
4. [Submit the transaction](/get-started.md#action-composability-engine).

## Repay

Repaying reduces the debt of a CDP you own. A partial repayment leaves the CDP open with less debt. A full repayment closes it and returns all of its collateral.

1. Select **Repay** on the CDP.
2. To close it, select **Repay all**.
3. To repay part of it, enter the **Debt to repay**, check **You pay**, then select **Repay**.
4. [Submit the transaction](/get-started.md#action-composability-engine).

**You pay** includes all of the CDP's accrued interest, even when you repay only part of the debt.

On desktop, you can close several CDPs at once: switch to the table layout, select them and choose **Repay** below the table.

### Partial repayment and the rate cap

If the market rate is above your CDP's rate cap, repaying part of the debt also raises the cap to the market rate. The app shows the new cap before you confirm. The CDP then pays the market rate and is no longer redeemable.

## Merge

Merging combines several of your CDPs for the same synthetic into one. Their collateral and debt are combined, including any accrued interest, and the merged CDP takes the lowest rate cap among them.

1. On desktop, switch to the table layout and select at least two CDPs for the same synthetic.
2. Select **Merge** below the table.
3. Check the merged CDP in the transaction review, then submit the transaction.

The original CDPs are closed when the transaction is confirmed, and the merged CDP replaces them.

## Claim leftover collateral

If someone redeems or liquidates your CDP in full, the collateral they do not take is set aside for you to claim. Open **Portfolio**, find **Leftover collateral to claim**, select **Claim** and sign the transaction.
