Opening market workspace
Protocol / Robinhood Chain mainnet
Policy rules, made explicit.
Active on Robinhood Chain Mainnet for admitted stock tokens and counterassets. Pricing modes, session fees, and flow limits are enforced directly onchain by the hook.
Fee engine
Session fee
The hook applies the session base fee and takes the maximum of bell, corporate-action, and repricing guards. Unknown calendar state fails closed. A checked pool steps aside when its external price is unavailable; a market-price pool is never affected.
Flow control
Flow budgets
Per-trade T, rolling W, and closure-episode C are raw token units per currency. Adding liquidity never raises caps or refills spent budgets.
Pool type
Checked priceExternal price check
Both assets need an approved external price source. The pool keeps trading close to it while the source is available. When it is not, the pool steps aside to its own market price with a 1% fee and the tightest flow caps, bounded by the calendar interval and closure budget.
Pool type
Market priceOwn-market pricing
Prices come from the pool liquidity itself and never wait for an external feed. Session fees and raw-unit flow limits still apply, but no outside price is claimed and no USD valuation is shown.
Recovery
Recovery and exit
Trading resumes only after required fresh checkpoints and recovery delay. The connected Positions page discovers wallet-owned BELL NFTs and offers direct add, minimum-output in-kind removal, and fee collection through PositionManager.
