NVDA Printer (v1): quick start
:::note The first Stock Yield vault
This page describes the NVDA Printer, the first-generation vault (BrokerEpochVault), which keeps running on its
own contracts. The eight v2 funds (EpochFund: seven stocks, covered calls and a wheel, transferable shares,
premium kept in NAV, no exit pool) are a separate set of contracts with different rules: see the
Stock Yield funds (v2) user guide.
:::
Hold NVDA, sell a call on it every week, collect the premium every Friday. The upside above the strike is what you sell; NVDA's downside stays yours. The rules page has every number and every role.
Four steps
- Stake 10,000 HEDGE (1,000,000 before 2026-10-18). It is the deposit pass. It stays staked while you have money in the vault, and unstaking takes a request and 7 days.
- Deposit NVDA, or USDG. USDG is swapped to NVDA in the pool, never at more than 1% worse than the oracle price, or the deposit fails.
- Monday 09:30 ET deposits close; at 09:35 the vault sells one call. It is a listed NVDA call expiring that Friday, 1% to 6.5% above the price: farther when options are expensive, nearer in quiet weeks. The buyer's premium is paid into the vault contract at that moment.
- Friday ~16:10 ET the week settles at NVDA's official close. Claim the premium in USDG, or turn on auto-reinvest and it becomes NVDA for next week.
One week
| When (ET) | What happens | What you can do |
|---|---|---|
| Fri ~16:10 → Mon 09:30 | Taking deposits | Deposit, cancel, get shares back within about an hour |
| Mon 09:30 | Deposits close; this week's NVDA is fixed | New deposits wait for next week |
| Mon 09:35 | The call is sold; the premium is in the vault | — |
| Mon 10:35 → Fri 14:59 | Earning | Exit now, or withdraw at expiry |
| Fri 15:59 | Expiry | — |
| Fri ~16:10 | Settled at the official close | Claim; withdrawals are paid |
Holidays and early closes move these times. The vault page always shows the current week's times.
What you earn, and what you give up
- The premium is what the buyer paid for the call, minus Hedgehood's 20% fee, split by vault shares. It is fixed the moment the call is sold, and it is yours however NVDA moves.
- NVDA closes Friday at or below the strike: you keep all your NVDA and the premium.
- NVDA closes above the strike (at most about a 40% chance in any week): the buyer takes, in NVDA, the value above the strike. You keep the premium and everything else. Gains above the strike are exactly what you sold.
- NVDA falls: that is yours, as if you held it. The premium only cushions it.
Getting your money out
| When | Cost | You receive | |
|---|---|---|---|
| Cancel a queued deposit | Until it becomes shares | none | the NVDA, back in your wallet |
| Withdraw at expiry | any time; Keep it in cancels it | none | NVDA after the week settles (about an hour between weeks) |
| Exit now | locked weeks, 1 h after the sale to 1 h before expiry | 1%, plus buying back your part of the call | USDG or NVDA, at once |
A queued deposit becomes shares at the next hourly queue run while deposits are open; one made during a locked week waits until that week settles.
Who can touch your NVDA
- No admin withdrawal, no upgrade. The contracts cannot be replaced and have no function that sends your NVDA anywhere but to you. The owner (a Safe) sets parameters inside limits the contracts enforce on themselves.
- NVDA leaves your position only when you cancel, withdraw or exit, and when the week settles above the strike. The Vault's operator is a contract that can do one thing, submit the signed weekly sale, so no key can report a loss against your NVDA. Why that matters.
- Nobody can hold it longer than the week. Pausing stops new deposits and sales, never settlement, claims or cancellations. If our keeper stopped, anyone could settle the week: from 48 h after expiry at Chainlink's price, and after 7 days without any price as if the call expired worthless.
:::warning Read this part
NVDA can fall, and the vault holds NVDA. Upside above the strike is sold every week. The call's buyer is Hedgehood's own account. The contracts have been reviewed internally and tested; they have not had a third-party audit. Nothing here is investment advice or a promise of return.
