Flint

Your stocks, paid to wait.

Hold Apple and plan to keep holding it? Promise to sell it at a higher price you choose, by a Friday you choose, and a buyer pays you for that promise today. If the price never gets there, the shares come back to you and the money stays with you. Holding dollars instead? Promise to buy below today's price, and get paid the same way.

How it works

Four moments in the life of one option

A covered call on half an Apple share, from the day you write it to the Friday it ends.

1

Write

Pick a stock you hold, a strike above today's price and a Friday. Valorem locks the shares and gives you two things: the option, and a claim that is your receipt for what you locked.

2

List

Name your price. The listing goes on chain through Seaport, where anyone can see it and buy all of it or part of it. Until someone does, you can take it down.

3

Get paid

A buyer pays your price in dollars, straight to your wallet, in the same transaction that hands them the option. That money is yours whatever happens next.

4

Friday

If the buyer exercised, they paid the strike for your shares and your claim collects the dollars. If not, your claim collects your shares. Either way, you redeem it in one click.

Calls & puts

Two promises, both fully backed

Every option here is backed in full by what it promises. There is no borrowing, no margin call and no liquidation, because there is nothing to call.

Call Covered call

You hold shares. You promise to sell them at your strike, above today's price, any time before your Friday. The shares are locked until then.

  • You are paid now, whatever happens.
  • If the price stays under your strike, your shares come back on Friday. You keep them and the payment.
  • If it goes above, you sell at your strike. Everything above it goes to the buyer, not to you.

Put Cash-secured put

You hold dollars. You promise to buy shares at your strike, below today's price, any time before your Friday. The dollars are locked until then.

  • You are paid now, whatever happens.
  • If the price stays above your strike, your dollars come back on Friday. You keep them and the payment.
  • If it falls below, you buy at your strike, which is more than the shares are then worth.
WHY FLINT
Choose a price.
Give it time.
A price, a date, and a fully backed promise.

A clear view of either side.

Write a covered call on shares you hold, or a cash-secured put at a price you would accept. Choose the strike and expiry before you commit.

Buy an option to hold the right to exercise. The terms remain on chain, and every transaction starts in your wallet.

What it costs you

The payment is real. So is what you give up.

The reference interface reports a backtest of a one-week covered call, 5% above the price, on every stock we list, every Friday that Robinhood's own feeds cover. Each was priced fairly from that stock's measured swings. These are historical reference results, not Flint performance or a return forecast.

23%

of weeks, the shares were called away

Out of 204 stock-weeks across 35 stocks, Fridays Aug 7 to Sep 11. The fair-price model expected 24%.

382 pts

collected, against 274 pts given up

Premiums summed over every stock-week, as a share of each week's price, beside the gains handed over above the strike in the weeks the shares were called.

42%

given up in one week, by one stock

NBIS, the week of Aug 7: that much of the price went above the strike, to the buyer. A single week like that can outweigh months of payments.

This assumes a buyer paid a fair price. Nobody has to. On a new market, with few buyers, you may get less or sell nothing, and then the shares simply come back on Friday. The median fair payment was 1.43% of the price a week, and much less on steady stocks: Apple's measured swings are 21% a year. Covered calls trade away a stock's best weeks for a steady payment. Whether that suits you is your decision, and this is not advice. Every week and every number is in the docs.

Built on what's already here

Flint deploys nothing

Every transaction Flint builds is a call from your wallet to a contract that was on Robinhood Chain before this site existed. We hold no key, no role and no fee in any of them.

Valorem clearinghouse

Writes the option and holds the collateral until it is exercised or expires. Physically settled, fully collateralised, with no oracle and no liquidation. Its source on this chain matches Valorem's own repository line for line. Zellic audited that code; the copy here differs from the audited release in three lines, which the docs name.

0x9a7b…C0C0

Seaport 1.6

Moves the payment and the option in one transaction, or neither. A listing is a Seaport order you publish yourself, so the list of offers is Seaport's own public log. There is no private orderbook.

0x0000…B395

Robinhood's own prices

The price beside every option comes from Robinhood's feeds on this chain, not from a trading pool. The reference market scan found 35 of them and set aside 15 stocks whose "price feed" was a Uniswap pool's price read back.

How the list was made
ON CHAIN

Read the terms. Check the transaction.

The interface reads public contracts and creates transactions for your own wallet. Verify the network, assets and amounts before confirming.

Your wallet signs

Approvals, listings, purchases, exercise and redemption are separate, visible actions. Flint stores no private keys.

The market is public

Listings are read from Seaport events, and options and claims from Valorem balances.

No audit claimed

This is a new interface. Read the contract addresses, risks and integration notes in the docs.

Questions

Before you write one

Can I lose my shares?

With a covered call, yes, but only by selling them at your own price. If the stock is above your strike when the buyer exercises, your shares go to them and you get the strike in dollars, plus the payment you already received. You never get less than you agreed to. You do miss everything above the strike.

Can I get my shares back before Friday?

While your options are unsold, you can exercise them yourself. You pay the strike and take the shares back now, and your claim returns that money after expiry. Once a buyer holds them, the shares stay locked until they exercise or Friday passes. That is the promise they paid for.

What if nobody buys my listing?

Then nothing is paid. You can take the listing down, lower the price, or leave it. Your shares or dollars stay locked in Valorem until Friday and come back to you when you redeem your claim. This is a new market on a new chain, so expect few buyers at first. We would rather say so.

Who can exercise, and when?

Whoever holds the option, at any moment until Friday 20:00 UTC. That is 4pm in New York in summer, when the market closes. After that it is worthless and your claim collects everything. If several people wrote the same strike and date, Valorem spreads each exercise across their claims by its own fixed rule. Between them the claims always return exactly what was locked, according to the clearinghouse rules.

Does Flint charge anything?

No. There is no Flint fee and no Flint contract. Valorem has a 0.15% fee switch that belongs to whoever deployed it. It is off as of the last check, and the app reads it live before every transaction and adds it to what you approve if it is ever on. You pay the chain's gas, measured in the docs.

Is this audited?

Flint itself is not audited, and there is no Flint contract to audit. It is a web page that builds transactions. Valorem's code was audited by Zellic, and Seaport by several firms. The copy of Valorem on this chain differs from the audited release in three named lines. Neither contract was deployed or is controlled by us.

Is this investment advice?

No. Options move money in ways that surprise people. A covered call caps your gains, and a put can make you buy a falling stock. Read what it costs you before you write one. Tokenized stocks on Robinhood Chain are not available everywhere.

Hold it anyway? Get paid to.

Pick a stock, a strike and a Friday. The app shows a fair price before you name yours.
