Corporate Actions
How splits, distributions, mergers, symbol changes and halts affect Stock Token quantities, prices and payoff terms.
#Multiplier and metadata adjustments
Robinhood publishes corporate-action records and multiplier metadata through the Stock Token API. Scheduled multiplier values are also readable onchain. Integrations should reconcile the asset record, token state and price-feed state before applying an adjustment.
| Event | Primary concern |
|---|---|
| Forward split | Multiplier, strike and share-equivalent quantity must remain economically aligned |
| Reverse split | Precision, minimum quantities and strike conversion require careful rounding |
| Cash or stock distribution | Reinvestment can change the multiplier and per-token price |
| Merger or spin-off | One instrument may map into cash, another asset or multiple components |
| Symbol or name change | Ticker metadata changes; asset uid and contract identity remain the safer keys |
| Trading halt | Underlying quotes, venue liquidity and oracle freshness can stop |
#Covered-call consistency
A corporate action must preserve the economic relationship among Stock Token quantity, strike, premium and call notional. Adjusting only one field changes the payoff.
- Freeze inconsistent creation or settlement states.
- Resolve pending multiplier values and effective timestamps.
- Version the asset identity and adjustment rule used by a position.
- Handle multi-asset outcomes explicitly rather than forcing them into a single-number payoff.
- Resume pricing only after the reference, multiplier and oracle agree.
