Risk parameters

Loan To Value

The maximum amount that can be borrowed for a specific mortgage is determined by the Loan To Value (LTV) ratio. For example, if the LTV is 75%, borrowers will be allowed to borrow 0.75 ETH worth of corresponding currency for every 1 ETH worth of collateral.

For a wallet, the maximum LTV is calculated as the weighted average of LTVs of collateral assets and their value. In particular, for a wallet that deposits the collateral assets that are worth in dollars C1,…,CnC_1, \dots ,C_n, and their LTVs corresponding to LTV1,…,LTVnLTV_1, \dots , LTV_n, maximum LTV is

C1×LTV1+⋯+Cn×LTVnC1+⋯+Cn\frac{C_1 \times LTV_1 + \cdots + C_n \times LTV_n }{C_1+\cdots+C_n}

Liquidation Threshold

The liquidation threshold is the percentage at which a position is defined as undercollateralised. For example, a Liquidation threshold of 80% means that if the value rises above 80% of the collateral, the position is undercollateralised and could be liquidated.

The difference between the Loan To Value and the Liquidation Threshold is a safety cushion for borrowers.

For each wallet, the liquidation threshold is calculated as the weighted average of the liquidation thresholds of the collateral assets and their value. In particular, for a wallet that deposits the collateral assets that are worth in dollars C1,…,CnC_1, \dots ,C_n, and their liquidation threshold, respectively, LT1,…,LTnLT_1, \dots, LT_n , the liquidation thresholds of wallet is

C1×LT1+⋯+Cn×LTnC1+⋯+Cn\frac{C_1 \times LT_1 + \cdots + C_n \times LT_n}{C_1 + \cdots + C_n}

Health Factor

For a wallet, these risk parameters enable the calculation of the health factor:

Hf=C1×LT1+⋯+Cn×LTnBH_f = \frac{C_1 \times LT_1+ \cdots + C_n \times LT_n}{B}

where BB is total borrows (in dollars), C1,…,CnC_1,\dots,C_n is the values (in dollars) of collateral assets, and LT1,…,LTnLT_1, \dots, LT_n is their liquidation threshold, respectively. When Hf<1H_f < 1 the loan may be liquidated to maintain solvency.

Liquidation penalty

Liquidation penalty is a bonus applied to the price of collateral assets purchased by liquidators as part of the liquidation of a loan that has reached the liquidation threshold.

Reserve Factor

The reserve factor allocates a share of the protocol's interests to a collector contract as reserve for the ecosystem.

Price Discovery

The frequency of price updates is determined by the liquidation strategy. We use a margin method, which means that prices are refreshed whenever the deviation exceeds a certain threshold. For the price feed, we rely on Chainlink's decentralized oracles.
