On Robinhood Chain you can borrow against Stock Tokens that trade 24/7. But the price oracle freezes at Friday's close while the token keeps floating. When the market reopens, liquidators fire against the gap. Hoodward watches that exposure and defends the position before they reach it.
Drag toward a negative gap, the price the market reopens to. Watch the health factor fall toward the liquidation line.
Stock Tokens are live on Robinhood Chain around the clock, but the real shares trade for roughly 32 hours a week. A lending protocol still checks your collateral against that oracle every block, so overnight and across the weekend your health factor rides on a price the market has not confirmed yet.
Most of a weekday and all weekend, your collateral is valued against a market that is shut. That striped amber band is when a liquidation can arrive with no warning, and it is exactly when no one is awake to move collateral.
When the stock market closes, Chainlink's tokenized equity feed holds Friday's last price and its timestamp goes stale. Meanwhile the token keeps trading on the AMM all weekend, a live bet on where Monday opens.
News breaks Saturday. Monday the feed snaps to a gapped price. If it gapped against you, your health factor can cross the line in a single block, and permissionless liquidators race to it the instant it turns a profit.
Two more windows: a feed that stops updating, and wrapper vs underlying deviation, the failure that once printed a tokenized stock at 77× its real price. Either can liquidate you on a number nobody has confirmed.
Read only, no permissions. See the real exposure on your vault before you hand anything over.

}| 95 | Tokenized stocks | Robinhood Chain launched with 95 Stock Tokens trading every hour of the week against a market open roughly 32 hours. That mismatch is the entire risk surface, and it exists only where tokenized equities live as collateral. |
| Live now | Real positions to defend | Morpho powered lending lets holders borrow against Stock Tokens today. Those vaults exist now, priced by Chainlink feeds, so there are live positions that need a defense layer already. |
| 100 ms | Reaction window | Robinhood Chain's 100 millisecond blocks let the guardian act inside the gap, topping up or unwinding before the reopen, not minutes after the liquidators have cleared. |
| 0 held | Non custodial | Hoodward never holds your assets. It acts on your own wallet inside the mandate you set, and revoking the session key stops it instantly. |
Monitoring and alerts are free. The guardian charges a small fee only on collateral it actually keeps out of liquidation, so it earns when you keep your position, and never when you lose it.
