| mark | max(oracle, pool TWAP), clamped at a band over the oracle. Every debt, health factor and liquidation in StockLend uses it. |
| band | How far over the oracle the mark may follow the pool. Frozen into each loan at the open, so a regime change cannot reach an existing one. |
| regime | Open or closed, from the on-chain trading calendar — or from a feed older than six hours, which is the fail-closed backstop, not the primary test. |
| buyIn | After maturity, anyone spends the borrower's collateral in the pool to buy the shares back, capped at the settlement price plus a slippage allowance that grows hourly. |
| writeOff | The collateral buys back neither the debt nor a single share. The shortfall is shared across lenders by share, and the leftover USDG goes to them. |
| weekend premium | The pool price over the frozen oracle during a closed session. What a borrower pays to sell into. |
| payout | Stock sent to $HEDGE holders by balance each round: the holders' share of the tax. What the treasury's stock earns buys back $HEDGE. |
| treasury inventory | Stock the treasury holds and works. Never sold, never shorted; lent on weekends, written against on weekdays. |
| covered call | Selling, for a premium, the right to buy the treasury's stock at a strike before expiry, with the stock locked as collateral. |
| any stock | The treasury can hold any stock token that has a lending or options market here; NVDA is only the first. |
| Hedgefun | One launch on Hedgefun Protocol v1: a token, a treasury that trades one real stock by a fixed strategy, and a pool. The contracts call it a strategy — strategies(id) — which is the word the ABI uses. |
| strategy | The five numbers a Hedgefun follows — tp1, tp2, dip, stop, lotBps — public before anyone buys and frozen at launch. |
| lot | A parcel of stock a Hedgefun treasury holds, with the cost it was booked at. It sells above that cost — tp1, then tp2 — unless the creator set a stop. |
| book | Costing stock that has arrived into a lot, at the live oracle price. book() is open to anyone and pays nothing; every other treasury call does it first. |
| bounty | What a treasury pays whoever sends one of its calls, out of what that call produced: bountyBps, 0.5% as shipped. It is why the rule runs with no keeper — see running a treasury. |
| USDG | The stablecoin every stock pool on Robinhood Chain is quoted against, and what collateral and fees are denominated in. |
| NAV share | A v2 fund share: an ERC-20 token worth its fraction of the fund's stock and USDG. Premium stays in the fund, so it shows up in the share price rather than as a reward. |
| cohort | The queue of deposit or redemption requests waiting for one cutoff. Priced and paid together at the freeze; cancellable until its own cutoff. |
| cutoff / freeze | Monday 09:30 ET: requests close, redemptions are paid in kind, deposits become shares at the live oracle price, and the week's holdings are fixed. |
| in kind | Paid in the fund's own assets, stock and USDG pro rata at the moment of the freeze, rather than in one of them. |
| wheel | Selling covered calls on the stock and cash-secured puts on the USDG, rotating between the two as each is assigned. |
| cash-secured put | Selling, for a premium, the obligation to buy the stock at a strike at expiry, with the USDG to pay for it locked as collateral. |
| uiMultiplier | The per-token factor that carries corporate actions. Chainlink's RHxxx / USD answer already includes it — see the three prices. |
