A tokenized stock option is a call or put whose underlying asset is a token tracking a listed share rather than the share itself. The payoff matches listed equity options: you sell upside above a strike for premium now, and you keep the downside. What changes is the size you can trade, the hours the asset can move onchain, and the fact that a token issuer sits between you and the share.
If you already write covered calls on crypto, the payoff is the same. Versus listed equity options in TradFi — where one contract covers 100 shares — tokenized assets let you size the write fractionally, so the position no longer has to be a hundred-share block.
Key takeaways
- A tokenized stock option has the same payoff as a listed equity option: premium now, capped upside or an obligation to buy later.
- Listed options cover 100 shares per contract. Tokenized shares are divisible, so a covered call can match the number of shares you hold.
- You add issuer, custodian and price-reference risk that a listed option does not have.
- Rights differ by issuer. Many tokens give economic exposure without shareholder rights.
Why contract size matters
One listed US equity option covers 100 shares. That convention decides who can write a covered call.
| Share price | 100 shares | What a listed covered call requires |
|---|---|---|
| $180 | $18,000 | The full block before you can sell one call |
| $420 | $42,000 | Same, at more than twice the capital |
| $900 | $90,000 | Effectively institutional |
Tokenized shares are divisible, and a quote-driven market does not need a fixed contract size. So the question moves from "can I afford 100 shares of this" to "will someone quote the size I actually hold". That matters most for holders of expensive single names, where a covered call is often attractive but hard to access in listed markets. Overcast currently sets no minimum trade size.
That is the benefit. The cost is that you have added an issuer and a custodian to a trade that previously involved only a broker and a clearing house.
The trade in plain numbers
Suppose you hold 20 tokenized NVDA shares with the share price at $180, and you sell a one-month call struck at $200 — about 11% above the current price.
- Collateral: 20 tokens locked against the call you sold.
- Premium: say $3.20 per share, so $64 received up front.
- If the share stays below $200 through expiry: the call expires, you keep the tokens and the $64.
- If it is above $200 and the call is exercised: you deliver the tokens, or pay the buyer the difference in value, depending on the settlement method — realising $200 per share plus the premium, and forgoing everything above that.
Note what the premium bought you: $64 now, in exchange for capping a 20-share position at $4,000 of value for a month. If the stock runs to $240, your upside was sold for $3.20 a share.
Cash-secured puts on tokenized equity
The mirror trade works the same way. You post stablecoin collateral, sell a put at the price you would be happy to buy at, and collect premium for the obligation. If the share falls through your strike, you buy at the strike — above the market — and keep the premium against that entry. If it does not, you keep the premium and your collateral unlocks.
Divisibility matters here too: a cash-secured put on a $900 share normally requires $90,000 of collateral per contract. Sized in tokens, the collateral tracks the exposure you actually want. The trade itself is explained in Crypto cash-secured puts.
Four differences from crypto assets
Sellers who come from ETH or BTC should account for these differences.
1. Trading hours depend on the tokenized product. The listed share still closes with its exchange. Some tokenized versions only trade in line with those hours; others keep trading overnight and on weekends. Continuous token markets can move while the share is shut — so overnight news may show up in the token first, or not at all if the product does not trade then. Check how your token trades before you treat it like crypto or like the listed stock. The option you sold spans whatever hours that product actually runs.
2. Corporate actions are real events. Splits, mergers, special dividends and delistings all have to be handled explicitly by the issuer and by the option's terms. Ask how a split adjusts your strike before you need the answer.
3. Dividends may or may not reach you. Some issuers pass them through, some do not. For a call seller this changes the calculus around dividend dates, which is precisely when early assignment risk concentrates in American-style listed markets.
4. Price can dislocate from the listed market. Automated market maker pools price from the ratio of assets in the pool, not from the exchange. A token can trade away from its share, particularly in thin pools or outside market hours. If your option settles on the token's price rather than the share's, that basis is your exposure.
Who issues the tokens, and what the rules say
The token you write against is issued by someone, and the structure decides what you hold.
| Structure | Example | What the holder gets |
|---|---|---|
| Issuer-native share | Superstate Opening Bell, used for Galaxy's GLXY shares | The token is the registered share, with voting and dividend rights |
| Custodian-backed wrapper | xStocks (Backed), Ondo Global Markets | Economic exposure to a share held in custody; no shareholder rights |
| Synthetic | Price-tracking tokens with no share behind them | A claim on a counterparty or protocol |
An xStock, for example, is a tracker certificate rather than the share itself, and Kraken states that xStocks do not confer ownership of the underlying equity. The structure descriptions follow QuickNode's 2026 overview.
On 17 September 2026 the US Securities and Exchange Commission granted a temporary, conditional Innovation Exemption that lets qualifying Tokenized Securities Venues trade tokenized US-listed stocks onchain. According to Skadden's summary, it runs for five years, requires the tokens to carry the same rights as the underlying stock, gives issuers notice and a chance to object to third-party tokens, and caps trading volume per stock. Synthetic securities are excluded.
How settlement works
Two questions decide what you are actually agreeing to.
- What settles? Physical delivery hands over the tokens. Cash-style settlement pays the difference in value and leaves you holding the tokens. The second keeps the asset but introduces a dependency on the reference price.
- What is the reference price? The token's own onchain price, a price feed that tracks the listed share, or the exchange close. Each has a different failure mode, and this is the single most important line in the contract for a tokenized stock.
The technical detail is in Overcast's settlement methods docs.
How Overcast approaches it
The price is set by request for quote, and the trade settles onchain. You choose the asset, amount, strike and expiry; trading desks quote a premium; you take one or none.
For tokenized equity, quote-driven sizing is the practical advantage. A listed market can only offer the contracts a platform has chosen to list, in the multiples it has chosen. A quote-driven market can price whatever a counterparty is willing to price, in the size you hold — which is why coverage extends across crypto majors and tokenized real-world assets rather than a fixed contract list. The trade-off is that there is no continuous public order book to check: you learn the price by asking, and the quality of the quote depends on who is competing for it.
How Overcast works covers the product; how to write a covered call covers the steps.
Risks, named
- Capped upside — the reason you were paid. Above the strike, the gain is not yours.
- Full downside — a covered call is not a hedge. If the share halves, you hold that.
- Issuer and custodian risk — the token is only as good as the entity backing it and the share it holds.
- Tracking risk — the token can trade away from the listed share, especially outside market hours.
- Gap risk — the share's exchange closes; your option does not.
- Software and price-feed risk — the escrow is code, and some settlement methods rely on an outside price.
- Jurisdiction — tokenized equity products are restricted in some places, and that can change during the life of your option.
FAQ
Does the covered-call structure still work?
Yes: you hold the tokenized shares as collateral, sell a call at a strike above the current price, and collect premium. Availability depends on the platform and on whether a counterparty will quote your asset and size.
Can I sell covered calls with less than 100 shares?
Yes on Overcast. Tokenized shares are divisible, and Overcast currently sets no minimum trade size, so you can sell a covered call on the number of shares you actually hold — 10, 20 or any other size a desk will quote. In listed US equity options the answer is no: one contract covers 100 shares. That removes a capital barrier; it does not change the payoff or the risks.
What happens to my option if the stock splits or pays a dividend?
It depends on the issuer's handling of the corporate action and on the option's terms. Confirm both before you write, because a split changes the relationship between your strike and the share, and an unpassed dividend changes what you are being paid for.
Is a tokenized stock option the same as a listed equity option?
Economically, the payoff is the same. The differences are in the plumbing: who holds the asset, what price settlement references, whether the contract has a 100-share multiplier, and which rules apply to the platform you trade on.
What price does settlement use?
Either the token's onchain price, a price feed that tracks the listed share, or an exchange close, depending on the settlement method. For a tokenized stock this is the term to read first, since it determines whether a dislocation between token and share works for or against you.
