Oracle

Pricing collateral, corporate actions, and what happens when a feed fails.

Robinhood Stock Tokens have onchain Chainlink price feeds, and those are the canonical valuation source wherever supported. At 97% LTV, price latency is the binding risk in the whole system — the gap between liquidation and insolvency is two points, and a stale feed spends it.

Required checks

• Price is greater than zero
• Feed is valid and not stale
• Asset is active in the registry
• Trading-halt status considered
• Corporate-action multiplier applied

Corporate actions

Stock Tokens use an onchain multiplier for splits and dividends. A holder’s raw ERC-20 balance can stay constant while the multiplier changes what it represents, so collateral must never be valued from the raw balance alone.

Value = Token Balance × Effective Multiplier × Oracle Price

Failure handling

If a feed becomes invalid the protocol stops new borrowing and stops collateral increases, while existing positions remain protected. Critically, it must not liquidate against a stale or invalid price — a bad feed is not evidence that a position is unhealthy.
