Position Management

Where to manage

• Open Dashboard page and locate your position card.

  
• Click Manage on the position card.

  
• In the Manage panel, use the tabs:

  • Deposit

  • Withdraw

  • Borrow

  • Repay

    • Repay with USDB

    • Repay with collateral

What the position card shows

• Collateral amount & value, Debt, and fixed interest rate.

• CR (Collateral Ratio) with a health bar

• Market Price and Liquidation Price

  

Health bar colors:

• Green = conservative

• White = normal

• Yellow = aggressive

• Red = very risky

• Liquidation label = Minimal Collateral Ratio of the Collateral type

Actions

The after-action simulation appears on every tab to preview CR and Liquidation Price before you confirm.

Deposit(add collateral)

1. Go to Deposit and enter the amount to add.

2. Review the after-action CR and Liquidation Price.

3. Confirm(Deposit).

Effect: CR increases; Liquidation Price moves lower (safer).

Borrow more USDB

1. Go to Borrow and enter the amount of USDB you want to borrow.

2. Review the after-action CR and Liquidation Price (CR must remain ≥ MCR(Liquidation).

3. Confirm(Borrow).

Effect: Debt increases; CR decreases; Liquidation Price moves higher (riskier). Fixed interest rate is based on debt amount

Withdraw collateral(partially)

1. Go to Withdraw and enter the amount to take out.

2. Review the after-action CR and Liquidation Price (CR must remain ≥ MCR(Liquidation).

3. Confirm(Withdraw).

Max withdraw note: the UI shows a max-withdraw estimate that trends your CR close to the MCR line.

Effect: CR decreases; Liquidation Price moves higher (riskier).

Repay debts

Repay with USDB

• Enter the amount of USDB to repay and confirm.

• Max repay behavior:

  • If wallet USDB balance ≥ total debt, Max fills the entire outstanding debt (including real-time interest).

  • Otherwise, Max uses your full wallet balance.

• Partial repay is supported.

Effect: Debt decreases; collateral remain the same. CR increase(Safer).

Repay with collateral

• For supported assets, sell a portion of collateral into USDB and repay in one flow.

• The modal previews: collateral to sell → USDB repaid → new CR.

• Under the hood, the protocol routes the steps atomically; availability depends on on-chain DEX liquidity.

Effect: Debt decreases; collateral also decreases. CR typically improves if the debt reduction is proportionally larger than collateral sold.

Close position

Close fully repays the position and returns all remaining collateral to your wallet in a single transaction. Choose one of the two paths:

• Close — Repay with USDB

  • Requirement: your wallet’s USDB balance must be ≥ total debt.

  • What happens: repays the entire debt using your USDB and withdraws 100% of the collateral back to your wallet.

• Close — Repay with collateral

  • Availability: always available(Slippage < your setting).

  • What happens: sells a portion of collateral into USDB, repays all debt, then withdraws the remaining collateral to your wallet.

  • The modal shows a preview: collateral used(to sell) → USDB repaid → collateral left.

Examples

Shared assumptions

• Collateral: 1,000 SUI

• Market price: $5.00 per SUI → Collateral Value $5,000

• Debt: 4,000 USDB

• MCR (Liquidation) = 110% (1.10)

• Baseline: CR = 5,000 / 4,000 = 1.25 (125%)

• Liquidation Price = (1.10 × 4,000) / 1,000(SUI) = $4.40 per SUI

A) Deposit 200 SUI

• New collateral = 1,200 SUI (value $6,000)

• New CR = 6,000 / 4,000 = 1.50 (150%)

• New Liquidation Price = (1.10 × 4,000) / 1,200(SUI) ≈ $3.67 per SUI

B) Repay with collateral 500 USDB

• At $5.00/SUI (ignoring routing fees), sell ~100 SUI → ~500 USDB to repay.

• New collateral = 900 SUI (value $4,500); New Debt = 3,500 USDB

• New CR = 4,500 / 3,500 ≈ 1.286 (128.6%)

• New Liquidation Price = (1.10 × 3,500) / 900 ≈ $4.28 per SUI
