# How to Use RIZ v2

RIZ v2 is Radiant's isolated lending infrastructure built on Morpho's contract architecture. Each market consists of exactly two assets: one **collateral** and one **loan asset**. These roles are fixed per market and clearly labeled in the UI.

### Navigating to Isolated Markets

Access RIZ v2 by clicking **Isolated** in the top navigation bar.

The market list displays all available isolated pairs in the format **Collateral / Loan**, alongside:

* **Deposit %** — current APY for supplying the loan asset
* **Borrow %** — current APY for borrowing the loan asset
* **Available Liquidity** — liquidity available to borrow
* **Utilization Rate** — percentage of supplied liquidity currently borrowed

Select a market to open its detail page.

### Understanding a Market

Each market detail page shows two assets with distinct roles:

| Label          | Function                                                |
| -------------- | ------------------------------------------------------- |
| **Collateral** | Deposited to back a borrow. Cannot be borrowed.         |
| **Loan asset** | Supplied to earn yield, or borrowed against collateral. |

> **Example:** In the syrupUSDC / USDC market:
>
> * syrupUSDC → Collateral only
> * USDC → Loan asset (supply to earn, or borrow against syrupUSDC)

Each market also shows its own **Health Factor**, **Your Supplies**, and **Your Borrows,** all scoped to that specific market. Positions in one RIZ market do not affect another.

### Deposit

Click the **Deposit** tab inside a market.

Use the dropdown to select which asset to deposit:

* **Collateral asset** → to back a future borrow
* **Loan asset** → to earn supply APY

Enter the amount and click **Continue** to submit the transaction.

> If you deposit only the loan asset without collateral, you earn yield but cannot borrow from that market.

### Borrow

To borrow, you must first have collateral deposited in the market.

Click the **Borrow** tab, enter the amount of the loan asset you want to borrow, and click **Continue**.

Your borrowing capacity is determined by the collateral amount and the market's **Max LTV** parameter, visible in the **Reserve Status & Configuration** section at the bottom of the market page.

> Borrowing is only possible within the market where your collateral is deposited. Collateral in one RIZ market cannot be used to borrow from another market or from Core.

### Health Factor

Each RIZ v2 market has its own isolated health factor.

The health factor reflects:

* **Borrowing power used** — percentage of available credit used
* **Current LTV** — ratio of debt to collateral value

If the health factor drops below 1.0, the position becomes eligible for liquidation.

### Withdraw

Click the **Withdraw** tab to remove supplied assets from a market.

> If you have an active borrow, withdrawing collateral will affect your health factor. Repay part or all of your borrow before withdrawing if needed.

### Repay

Click the **Repay** tab to reduce or close an active borrow.

Repaying in full restores full access to your collateral for withdrawal.

### Reserve Status & Configuration

At the bottom of each market page, the **Reserve Status & Configuration** panel shows parameters for each asset in the market.

Toggle between **Collateral** and **Loan** asset views to see:

| Parameter                 | Description                                  |
| ------------------------- | -------------------------------------------- |
| **Max LTV**               | Maximum loan-to-value ratio for borrowing    |
| **Liquidation threshold** | LTV at which liquidation becomes possible    |
| **Liquidation penalty**   | Fee applied to collateral during liquidation |
| **Collateral usage**      | Whether the asset can be used as collateral  |

### Coming from RIZ v1?

If you have active positions in RIZ v1 markets, those markets are being phased out. Manual migration is required.
