🌊Liquidations

The Health Factor is a key metric in Voltage Lending. It indicates how safe a user’s borrow position is relative to the value of their collateral. If the health factor falls below 1, the position becomes eligible for liquidation.

Health Factor Formula

Health Factor = (Collateral Value × Liquidation Threshold) / Borrowed Value

• A Health Factor > 1 means your position is safe.

• A Health Factor < 1 means your loan may be liquidated.

Let’s say a user supplies $1,000 of USDC with an 80% liquidation threshold, and borrows $700 of another asset. The health factor would be:

($1,000 × 0.80) / $700 = 1.14

As long as the health factor stays above 1.0, the user remains safe.

How Liquidation Works

When a borrower’s health factor drops below 1, a portion of their debt becomes eligible for liquidation. This means that a liquidator can repay up to 50% of the user’s borrowed amount and, in exchange, receive a discounted portion of the collateral.

• Triggered by: Drop in collateral value or increase in borrow value

• Repaid by: A third-party liquidator (any user on the network)

• Liquidation Bonus: Applied to the collateral seized by the liquidator

Liquidation helps maintain the solvency of the protocol and ensures that funds remain available for other users.

Why Your Health Factor May Drop

• Collateral loses value (e.g. market dip)

• Borrowed asset increases in value

• Accrued interest increases your borrow position

• Stablecoins depeg or experience volatility

To avoid liquidation, users can:

• Repay part of their borrowed amount

• Supply more collateral

• Monitor asset prices regularly (via the dashboard)

Who Can Liquidate?

Anyone. Liquidations on Voltage are permissionless. Users or bots can monitor the protocol and initiate a liquidation as soon as a position becomes unhealthy. It’s a competitive process often done by bots or experienced DeFi users.

During Beta, liquidation mechanics are active. While caps are in place, users should monitor their health factor closely to avoid loss of collateral.
