How does Collateral and Borrowing work?

Understanding collateral and Borrowing with your Cash Card

Updated this week

In Borrow Mode, your borrowing limit depends on the value of the assets in your Vault:

  • Different assets may have different LTV values

  • The system ensures you maintain a healthy collateral ratio

  • If collateral values drop significantly, you may need to add more funds or repay some debt

Supported Tokens ​and their LTV (Loan-to-value)

The following tokens are available for deposits and collateral:

Core Assets:

  • wETH (Wrapped Ethereum) - 55% LTV

  • wHYPE (Wrapped Hype) - 45% LTV

  • USDC (USD Coin) - 90% LTV

  • USDT (Tether USDt) - 90% LTV

  • frxUSD (Frax USD) - 90% LTV

  • SCR (Scroll) - 20% LTV

Platform Tokens:

  • ETHFI - 20% LTV

  • eBTC (Ether.fi's staked BTC) - 52% LTV

  • eUSD (Ether.fi's staked USD) - 80% LTV

  • weETH (Ether.fi's wrapped eETH) - 55% LTV

  • beHYPE (Etherfi's wrapped Hype) - 40% LTV

Ether.fi's Liquid Vaults Tokens:

Understanding Liquidation Risk

  • What is liquidation?

    • If your borrowing exceeds your maximum allowed amount (due to collateral value decreases or other factors), the system may liquidate some of your assets to maintain the health of your account.

  • How to avoid liquidation:

    • Monitor your borrowing power and total borrowings

    • Keep a healthy margin between what you've borrowed and your maximum borrowing limit

    • Add additional collateral or repay some debt if your position approaches risky levels

    • Ensure you maintain sufficient collateral value for any borrowed funds

  • What happens during liquidation:

    • The Debt Manager controls the liquidation process

    • Specific tokens from your Vault are transferred to the liquidator

    • 50% of your total collateral is liquidated first; if the position is still unhealthy, the rest of the assets are liquidated as well

    • The liquidator decides what they want. Each asset has a liquidation bonus. A higher bonus means more profit to the liquidator, but they also need to assess whether there is enough liquidity to swap those assets. Higher bonuses are often assigned to riskier or less liquid tokens. So it depends on the liquidator; they determine the priority based on what makes sense for them.

  • After liquidation: Your Vault remains operational, and you can continue using the remaining assets either as collateral or for Direct Pay mode spending

Liquidation Cheat Terms:

LTV (Loan-to-Value)

LTV is the maximum amount you can borrow against your collateral when initially taking out a loan.

Liquidation Threshold

This is the point at which your position becomes eligible for liquidation. If your borrowed amount exceeds this percentage of your collateral value, liquidators can step in.

Liquidation Bonus

This is the incentive paid to liquidators who repay bad debt. They receive the collateral plus this bonus percentage.

Example scenarios:

Example 1: USDC Collateral (Partial Liquidation Sufficient)

Initial Position:

  • Collateral: $10,000 USDC

  • Borrowed: $9,000 (90% LTV - maximum safe borrow)

  • After interest accrual, debt grows to $9,520

Liquidation Triggered: Debt ($9,520) exceeds 95% of collateral ($9,500)

Step 1 - 50% Liquidation:

  • Liquidator repays: $4,760 (50% of $9,520 debt)

  • Liquidator receives: $4,807.60 USDC ($4,760 + 1% bonus)

  • Remaining debt: $4,760

  • Remaining collateral: $5,192.40 USDC

Health Check:

  • Debt-to-collateral ratio: $4,760 ÷ $5,192.40 = 91.7%

  • Position is now healthy (below 95% threshold)

  • No further liquidation needed ✓

Example 2: weETH Collateral (Full Liquidation Required)

Initial Position:

  • Collateral: $10,000 weETH

  • Borrowed: $5,500 (55% LTV - maximum safe borrow)

  • weETH USD market value drops 30%, collateral now worth $7,000

  • Current debt-to-collateral: $5,500 ÷ $7,000 = 78.6%

Liquidation Triggered: 78.6% exceeds 75% threshold

Step 1 - 50% Liquidation:

  • Liquidator repays: $2,750 (50% of $5,500 debt)

  • Liquidator receives: $2,846.25 worth of weETH ($2,750 + 3.5% bonus)

  • Remaining debt: $2,750

  • Remaining collateral: $4,153.75 worth of weETH

Health Check:

  • Debt-to-collateral ratio: $2,750 ÷ $4,153.75 = 66.2%

  • Position is healthy (below 75% threshold)

  • No further liquidation needed ✓

Alternative Scenario - Full Liquidation: If weETH price had dropped 35% instead (collateral worth $6,500):

After 50% liquidation:

  • Remaining debt: $2,750

  • Remaining collateral: $3,653.75 worth of weETH

  • Debt-to-collateral: $2,750 ÷ $3,653.75 = 75.3%

  • Still above 75% threshold → Full liquidation executed

Step 2 - Remaining 50% Liquidation:

  • Liquidator repays: $2,750

  • Liquidator receives: $2,846.25 worth of weETH

  • Position fully closed
