An app store for Arc · 12 apps, all finished, all live
The mission: build every new kind of app that Arc makes possible, and hand each one to someone who will run it. Twelve are finished and live. Pick one, or ask for one nobody has built yet, and it is yours.
Each one is a real example, on the real rules. Tap one to see it up close.
Own one
Nothing here is downloaded and nothing is rented. Pick one of the twelve, or ask for one that does not exist yet, and it is handed over whole: the code, the deployment, and the contract on Arc mainnet with your wallet as the one it pays.
It earns.
The revenue line is written into the contract and paid to the owner’s wallet, on chain, with every act. Round keeps 1% of every pot. Skim keeps 10% of every premium. Charter keeps 0.25% of every payment through a page. Nothing passes through me.
It is yours.
You deploy it from your own wallet and register it yourself, so no key of yours ever exists anywhere else. Your repository, your hosting, your contract. Change it, hand it to another developer, sell it. There is no platform in between and nothing to cancel.
It is fundable.
Arc and Circle are funding builders now, and what their programmes ask to see is a real product on Arc with people using it. Each one here ships live on mainnet with its own pitch page and its own deploy page, written for exactly that.
Arc’s programmes, as Arc lists them
Just getting started
MicrograntsFor early experiments, prototypes and promising ideas that need a push.
Already shipping
Developer grantsMilestone-based funding and technical guidance for production applications already on Arc.
Building a company
Arc Builders FundStrategic investment and introductions through Circle Ventures for category-defining companies.
The community
Arc HouseHackathons, accelerators, workshops and office hours for people building on Arc.
Those pages are Arc’s and Circle’s, and they decide. What I do is make sure that when you apply, the product already exists, works, and earns.
Have one built
Or something that does not exist yet, on the same foundation. Any language. Answered by me, not a form.
1Today
Send a message
Say which of the twelve, or describe what you need in your own words. Any language. It goes to me, not a form.
2Tomorrow
Twenty minutes
We settle three things: what it is called, what the rules are, and what the contract earns you. A price if you want one; free if not.
3Days
I build it
Its own look, its own first screen, a person and a story on it, every contract function with a screen, tested end to end on a local Arc chain. You watch it grow.
4One press
You deploy it
From its deploy page, with your own wallet, for a few cents of gas. No key of yours ever leaves your browser.
5For good
It is yours
The repository, the deployment, the contract, the revenue line inside it. The fees go to your wallet, not mine. Nothing to cancel.
Its own look
Twelve looks on this page, none alike. Yours is drawn for what it is, not skinned from a template.
Real before anyone signs in
A labelled example runs on the real rules, so a stranger with no wallet understands it in ten seconds.
A contract that earns
The revenue line is inside the contract and paid to your wallet: a share of every pot, premium, fee or deposit.
Every function on a screen
Nothing that only a developer can do. If the contract can do it, there is a button for it.
Fast on a phone
Ninety and above on Google’s mobile score and a hundred on accessibility, across all twelve.
A pitch and a deploy page
Each product carries its own pitch for a grant or a partner, and a page to deploy it from any wallet.
Arc’s request for builders · 16 September 2026
Arc’s team wrote that programmable money makes things buildable that were not buildable before, named the four places where the biggest opportunities sit, and put grants behind them. The twelve on this page were built to those four. Every one is live on Arc mainnet, and every one can be owned.

The twelve
Each is a product for a person in a real place, not a wallet or a dashboard, and each is shown here running on its own example so you can see what it does before you decide anything.
01 / 12
AI agents that pay for themselves
Pip is a courier for a florist. It pays for every thought from its own wallet, and when the money runs out it lies down. Elif keeps it alive.
02 / 12
Money that obeys the rules you write
You handed your brother the shop’s money. You wrote the rules on one page. The money obeys the page, and every refusal is stamped on the record.
03 / 12
Family money that finds its way home
A household with a quiet clock. If you go quiet, the lamps come on one by one and the money finds its way home, with your letters.
04 / 12
Pay a whole crew the second you say yes
Post a big job with the money in it. The people who take it hire people. When you say yes, every one of them is paid in the same second.
05 / 12
Managers race for your savings
Stables race for your savings. Each one bids a rate, delivers in cash, and is cut the moment it pays less than it promised.
06 / 12
Wages priced in months of living
Amaka is paid 1.2 months of living a month, priced by the town’s own board. When rice goes up at the market, the meter speeds up.
07 / 12
A till that borrows for itself
A stall puts every sale through a till on Arc. Its books are live to the second, and the till borrows against them by itself.
08 / 12
Insurance that pays before it checks
Amara’s bike was stolen at six in the morning. She filed from the kerb and was paid before she got home. The checking came after.
09 / 12
A savings circle that runs itself
Eight people, fifty dollars a week, and each week one of them takes the whole pot. Nobody keeps the notebook: the pot pays itself.
10 / 12
Hourly cover for hourly workers
A rider taps on when the shift starts and is covered by the second, from a small jar of her own money. Tap off, and it stops.
11 / 12
Credit that grows with every on-time day
Day 41. A ten-dollar line became twenty-seven, one on-time day at a time, backed by her mum and a stranger who liked the streak.
12 / 12
A town with its own money
San Roque has its own money. Every coin remembers how many hands it passed through, and leaves free once it has gone round.
Why these, and why here
None of the twelve is a wallet, an exchange, a dashboard or a token. Each is a thing a person in a real place needs, and each only works because a dollar on Arc is final in under a second, for a fraction of a cent. None of them could run on a rail that takes a day.
Typical times for the money to be final; Arc’s is its block time, measured live at the top of this page.
Final in under a second
A claim is paid before the claimant gets home. A pot tips the moment a round closes. Nothing sits as pending for days.
In dollars
Arc’s own currency is USDC, so every amount on every screen is a dollar. There is no token to buy and nothing that goes up and down.
For a fraction of a cent
Pay can stream by the second and cover can switch on with a tap, because a payment costs less than the paper it would have been printed on.
With no account
A stranger understands each product in ten seconds from a labelled example, and signs in with a face or a fingerprint only to act.
The proof
Nothing here is a mock-up. Each product has its own contract deployed from an ordinary wallet, registered on chain, read by the app at runtime. The examples say they are examples; everything else is the chain.
| Product | Contract on Arc | Whoever runs it earns | Functions | Tests |
|---|---|---|---|---|
| 01Heartbeat | 0xD027…df73 | 1% of what keeps a creature alive | 5 | 5 |
| 02Charter | 0x584C…98D7 | 0.25% of every payment through a page | 11 | 13 |
| 03Heir | 0xCCe3…e33E | 0.25% a year in custody | 8 | 11 |
| 04Cascade | 0x1512…9993 | 1% of every job | 11 | 16 |

| 10Skim | 0x4828…F291 | 10% of every premium | 12 | 8 |
| 11Streak | 0xF352…689C | a fifth of every fee | 8 | 10 |
| 12Barangay | 0x157A…28D7 | a fifth of what leaving costs | 6 | 6 |
They share code and never a look. A thirteenth goes live in under an hour, and a bespoke one in days.
Connect, balance, send, stream, escrow, attest. Typed, never throws, every write optimistic with a rollback.
Numerals that roll because money moved. Live data at sixty frames a second that degrades gracefully.
One token file per product: palette, faces, density, motion, voice. Change it and the whole product follows.
Every product is real before a wallet is connected. Seeded, live-feeling, honestly labelled.
Every question
In the sense that matters: a catalogue of finished products you can pick from, each one running so you can try it before you decide. In the sense that does not: nothing is downloaded and nothing is rented. The one you pick becomes yours, code, deployment and contract.
A post from Arc’s team on 16 September 2026. It names four frontiers where programmable money makes something buildable that was not buildable before: global money and embedded finance, the agentic economy, onchain credit and collateral, and the intelligent account. It lists what Arc would like to see on each, and the grants and funding behind them. The twelve here were built to those four, three to each.
No. None is a wallet, an exchange, a dashboard or a token. Each one is a product for a person in a real place: a rider, a stall, a town, a family, a savings circle. Each one needs the half second to work at all, which is why they did not exist before.
Yes, and it is a good reason to have one built. Arc’s microgrants are for early experiments, its developer grants for production applications already on Arc, and the Builders Fund for companies. Each product here is live on mainnet with its own pitch page and deploy page. I will help with the application; Arc and Circle decide. What I promise is that the product already exists, works, and earns when you apply.
You deploy the contract from your own wallet, so its platform address is yours and its fees go to you. You hold the repository and the hosting account. I keep nothing that you need to keep running. If you want to change it, hand it to another developer, or sell it, you can.
Your own repository, your own deployment, your own contract on Arc with the revenue line inside it, a pitch page and a deploy page, all with your name on. The fees the contract earns go to your wallet. No platform fee, no subscription, no lock-in.
One of the twelve, made yours, in days: your name, your rules, your fee line, your colours if you want them. Something that does not exist yet, on the same foundation, in one to three weeks. You see a first version you can press within the week.
Name your price, or free. Tell me what it is worth to you and what you can do. If the answer is nothing yet, say so; that is fine. Deploying costs a few cents of gas. Running it costs nothing.
Because a product with a real town, a real market or a real fleet behind it is worth more to me than a fee, and because the foundation under these twelve makes the next one cheap for me to make. Ask for a price if you would rather pay one.
Yes. It is a normal codebase you own, on a normal hosting account you own, and a contract you deployed. Change it, hand it to another developer, or ask me. Nothing is hidden and nothing phones home.
Then you still have everything: the code, the deployment, the contract and its revenue. That is the point of you deploying it from your own wallet rather than me.
No. You need a wallet on Arc, which is an app on your phone that signs with your face or fingerprint. You press one button to deploy and one to register. I walk you through it on WhatsApp.
No. Every product here works with no account and no wallet: a stranger understands it in ten seconds from a labelled example. They only sign in to act, and signing in is a passkey: face or fingerprint, nothing to install, nothing to pay.
Yes. Arc’s native currency is USDC, a dollar, so every amount on every screen is dollars. There is no token to buy and nothing that goes up and down.
A fraction of a cent, paid in dollars from the same balance. It is final in under a second, and the app tells them so.
No word like that appears on a customer screen anywhere on this page. They see a pot, a jar, a vest, a page of rules, a board. The chain is what makes it honest; it is not what they see.
Every write is checked before it is sent, and if the chain refuses it the app says why in plain words and nothing moves. There is no state where money is “pending” for days.
The contract, on chain, in dollars. Not me, not a company. What a contract may do is written in it and cannot be changed after it is deployed; every product’s about page says exactly what its contract does.
No. I never hold a key. You deploy the contract from your wallet, so the platform address is yours. The only thing a contract sends anywhere on its own is the fee line to your wallet.
Made-up people and example money running on the same arithmetic the contract does, so what you see is exactly what the chain would do. It is labelled as an example wherever you can act on it, and never shown next to real numbers.
Every contract has a test suite, and every product’s live layer is exercised end to end on a local Arc chain before it ships: every function, every screen, with real signatures.
Circle’s blockchain, the company behind USDC. Its native currency is the dollar, payments are final in under a second, and a transfer costs a fraction of a cent. It is what makes a wage by the second or a pot that pays itself possible.
Because a lot of products only exist at that speed. A claim paid before the claimant gets home, cover that switches on with a tap, a pot that tips the moment a round closes, pay that streams while you work. Slower rails do not make those worse; they make them impossible.
No. All twelve are on Arc mainnet, with real dollars. Every contract address on this page opens in Arc’s explorer.
One builder. I designed and built all twelve, the foundation under them, and this page. You talk to me directly and I answer myself, usually within the hour.
A message saying which product, or what you need in your own words, and what to call it. Everything else we settle in twenty minutes.
Any. Write in the language you think in.
