What this is
A place to lend and borrow against tokenised equities on Robinhood Chain. Each market pairs one collateral asset with one asset you can borrow, and every market is separate from every other: its own depositors, its own borrowers, its own risk. Nothing that happens in one market can reach another.
Lending
Supplying makes your asset available for borrowers to draw against, and you earn the interest they pay. The rate is not fixed. It rises as more of the pool is borrowed and falls as borrowers repay, so the yield reflects demand rather than a promise.
You can withdraw whatever is not currently lent out. If borrowers have drawn most of the pool, part of your balance stays put until they repay or someone else supplies. This is the trade every lending market makes: a fully used pool pays the most and exits the slowest.
Borrowing
Post collateral, then draw against it. How much you can draw is set by the market’s liquidation limit — a market with a 62.5% limit lets you borrow up to 62.50 for every 100 of collateral value. Borrowing the maximum leaves no room for the price to move, so most borrowers stay well below it.
Interest accrues to your debt continuously. Repay any part of it at any time, and once the debt is clear the collateral is yours to withdraw.
Liquidation
If the value of your collateral falls far enough that your debt crosses the liquidation limit, anyone may repay part of that debt and take collateral in exchange, at a discount. That discount is what pays them for doing it, and it comes out of your position.
Liquidation is what protects lenders. It is also why the limit matters more than it looks: it is not a target to borrow up to, it is the line past which someone else decides what happens to your collateral.
Price age
Every market is valued against a price feed, and next to each market we show how long ago that price last moved. During a trading session it reads in minutes. Outside one it reads in hours, and across a weekend, in days.
This matters because a tokenised stock keeps trading when the shares behind it do not. While the exchange is shut the feed holds its last value, so a position’s loan-to-value stops moving too — not because the risk went away, but because nothing is measuring it. When the exchange reopens, the price catches up in a single step, and every position is re-measured at once against a number that may have travelled a long way.
A stale price is flagged, never blocked. Refusing to price an asset would freeze liquidations along with everything else, which leaves lenders worse off than a warning does. What to do with the information is your call.
Fees
This interface charges nothing. Borrowers pay interest to lenders, and liquidators earn their discount. There is no deposit fee, no withdrawal fee, and no cut taken in between.
Custody
Positions are held in your own name on chain and settle into audited lending contracts. We never take custody of your funds and have no ability to move, freeze, or reverse them. The same is true in the other direction: nothing here can be undone on your behalf, so check a transaction before you sign it.
