This section is aimed at lenders and borrowers. It regroups the different keywords you may find in the Hatom protocol and their definitions.
Money Markets or "MM"
We refer to the money market as any token listed in a lending network. A money market can be understood as a pool of tokens to which lenders provide liquidity and from where borrowers take liquidity.
The Utilisation rate is a percentage that shows how much of a money market’s total value is being borrowed. It can be calculated by dividing the (Total Value of Assets Borrowed) by (Total Value of Assets Supplied).
Collateral Factor or Loan to Value
The collateral Factor is expressed as a percentage. It’s a multiplier used to calculate the maximum amount you can borrow against your collateral. The collateral factor differs from one token to another. For example, if EGLD has a collateral factor of 80%, for every $1,000 of EGLD supplied, you can borrow $800 of any available token.
Borrow Limit Used
Borrow Limit Used is a percentage that indicates the ratio amount you currently have borrowed to the total amount you are allowed to borrow. For example, if you can borrow a maximum of $1,000 (as determined by the Collateral Factor of the supplied token), borrowing $750 would equate to 75% of the Borrow Limit Used.
The maximum of tokens that can be borrowed from a MM (best thought of in terms of a percentage of tokens in circulation, e.g., If there are 100,000,000 tokens in circulation, then a borrowCap of 5,000,000 is 5%)
Liquidation Factor/Health Factor
The liquidation Factor is a percentage that indicates the value at which liquidation occurs and can be thought of as the ratio between the supplied value and the borrowed value. For example, if a user deposits EGLD and has a Liquidation Factor of 75%. When the value of the borrowed positions reaches 75% of the supplied EGLD, a liquidation can occur. The liquidation Factor differs from one token to another.
Liquidation Limit Bar
The Liquidation Limit Bar is a percentage that indicates the ratio of your borrowed value to the borrowed value that would trigger liquidation. It tracks how close your borrow position is to being liquidated. When the Liquidation Limit attains 100%, you are permitted for liquidation. For Example, if a user supplies $1,000 EGLD as collateral and has a liquidation factor of 70% ( so the user’s position gets liquidated when his borrow value equals $700). If he borrows 1 MEX worth $350, his liquidation limit bar would be 50% ($350 Borrowed/$700 Liquidation Value.)
A liquidation Incentive is a cut in price at which a liquidator receives a user’s collateral when completing a liquidation. This discount encourages liquidators to complete liquidations to keep a healthy state.
The portion of borrower-paid interest (per second) to the reserve. The remainder of the borrower-paid interest goes to the MM’s suppliers.
A close Factor is a percentage that indicates the amount of a position that a liquidator can close at one time when performing a liquidation.
The maximum value (in USD) can be used as collateral to borrow against. To be used as collateral, the total active collateral in the said asset must be smaller than activeCollateralCapUSD
The Supply APY is a percentage that reflects the amount of interest a user would earn over one year for supplying tokens. On the other hand, The Borrow APY reflects the interest the borrowers pay for borrowing tokens.
HTokens are issued to lenders after supplying assets to a lending network. HTokens are exchanged for the underlying asset when users wish to withdraw their supplied assets.
The token that can be lent/borrowed in the MM.
The amount of underlying token held by the MM. The balance increases whenever tokens are deposited into the MM and decrease whenever tokens are borrowed from the MM.
The total amount of underlying token that the MM has set aside as a protocol fee. This amount increases as borrowers pay interest and decreases when the admin withdraws these tokens. The reserve can be used, among other things, as an insurance fund to cover the bad debt incurred by the MM.
