Terms

Adaptive Curve

The interest rate model used by Morpho markets. The app uses its shape, with a target utilization of 90%, to estimate how your own borrow moves the rate.

Approval

A transaction that lets a contract move a set amount of one of your tokens. On Robinhood Chain the app asks for the exact amount only.

APY

Annual percentage yield. A yearly rate that includes compounding. It is a snapshot of today and changes.

Borrow factor

On Kamino, a multiplier that makes some borrowed assets count more than one for one against your limit. Shown only when above 100%.

Borrow limit

The most you can borrow against your collateral, found by applying the max LTV to its value.

Collateral

The tokens you deposit to back a loan. On stockloan.fun, stock tokens.

Cross margin

One position where all deposits back all loans together. How Kamino works on Solana.

Debt

What you owe: the amount you borrowed plus interest that has built up.

Drop to liquidation

How far your collateral can fall in value before your health factor reaches 1.00, if nothing else changes.

Gas

The network fee for a transaction. Paid in SOL on Solana and ETH on Robinhood Chain.

Health factor

(Collateral value x liquidation threshold) / debt. Above 1.00 is safe from liquidation, below 1.00 can be liquidated.

Isolated market

A market where each loan is backed only by its own collateral. How Morpho works on Robinhood Chain: one market per stock.

Kamino Lend

The lending protocol stockloan.fun uses on Solana.

Liquidation

When a loan becomes unhealthy, others repay part of the debt and take some of the collateral plus a bonus.

Liquidation bonus

The extra collateral a liquidator receives as a reward. You pay for it.

Liquidation price

The price of a stock token at which your health factor reaches 1.00, if nothing else changes.

Liquidation threshold

The loan to value at which liquidation starts. On Morpho this is called LLTV.

LLTV

Liquidation loan to value. The single limit of a Morpho market. The app uses it as both max LTV and liquidation threshold.

LTV

Loan to value. Your debt divided by the value of your collateral.

Max LTV

The highest LTV a protocol lets you borrow up to for a given collateral token.

Morpho

The lending protocol stockloan.fun uses on Robinhood Chain: Morpho Blue markets and Morpho vaults.

Non custodial

The app never holds your funds or keys. Your wallet signs everything.

Oracle

A price feed that a protocol uses to value collateral and decide on liquidations.

Robinhood Stock Token

A token on Robinhood Chain tracking a stock, issued by Robinhood Assets (Jersey) Limited.

Simulation

A test run of a transaction before you sign it, to catch failures. Called preflight on Solana.

Stablecoin

A token meant to hold a steady value of one dollar, such as USDC or USDG.

Stock token

A token that tracks the price of a stock or ETF. It is not the share itself.

Supply APY

The yearly rate lenders earn at today's rates. Variable and not guaranteed.

USDG

Global Dollar, a dollar token used on both chains in the app.

Utilization

The share of a pool that is lent out. High utilization usually means higher rates and slower withdrawals.

Vault

A smart contract that takes your dollars and lends them out according to a curator's rules. You get shares that grow in value. The app uses Morpho vaults for lending on Robinhood Chain.

Weekend Guard

A helper in the app that warns about price gaps when the US stock market is closed and suggests a safer LTV.

xStocks

Tokenized stocks on Solana, issued by Backed Assets (JE) Limited.
