This is the deepest page in our Cardano introduction. Read it in layers. The main thread is for anyone. The asides are for readers who want the economics underneath. Take what is useful. Leave the rest.

Most explanations of a crypto asset start by calling it digital money and end by saying it will make you rich. We are going to do neither.

ADA is the asset native to the Cardano network. People use it to pay and be paid. Holding it is how the ledger stays secure and how holders can take part in how the network is governed. Its price moves — a lot — so it is an imperfect everyday currency. That is not the only way to see it.

Why would anyone accept something whose price jumps around?

The answer is older than crypto. A school of economic thought associated with Carl Menger and Ludwig von Mises asked a simple question: where does the value of money come from?^[1]^[2]

Their answer, held here as a careful framework rather than as settled fact, has three ideas worth carrying:

Value is subjective. Nothing is valuable "in itself." A thing has value because people judge it useful, scarce, and trustworthy. Gold, land, a dollar, and a digital asset are valued for the same human reasons, in different proportions.
Sound money is scarce money. What made gold a store of value for so long is that no one can easily make more of it. ADA is unusually disciplined on this point, and the detail matters. All 45 billion ADA already exist. The full amount was accounted for when the network launched. Roughly 36.5 billion is in circulation (mid-2026). The rest sits in the protocol's reserve and is released on a fixed schedule as staking rewards and treasury funding.^[3] Nothing new is being invented. Circulation still grows as that reserve pays out — on a published schedule nobody can change at will. That schedule is the property that matters. A national currency can be expanded by decision.
Money moves value across time. To accept any payment is to trust that what you receive will still be worth something later. That trust is the real substance of money.

For the economically curious. The third idea is time preference: people value goods now over goods later, and a sound store of value is one that does not quietly punish the patient saver through inflation. It is the same instinct behind accepting land, or gold, or a well-run currency. You take it today because you trust its future. A modern strand of this thinking has been applied to digital assets.^[4] We find it a useful lens — and, like all lenses, one to hold with care, not as dogma.

Money, or property?

ADA's price is volatile. It can move a great deal either way. You would not want your grocery budget swinging with a market.

Currency is not the only lens. Consider property.

When someone accepts a parcel of land as payment, they are not expecting a stable dollar value week to week. They accept it because, over time, they trust it to hold worth — and because it does useful work. Taking ADA as payment is closer to that: deferred payment. You accept an asset now, trusting its future, the way you might accept property.

And ADA has work beyond scarcity:

It runs the network. Every transaction on Cardano is paid for and secured in ADA. It has a job, not just a price.
It can help. Holders can delegate ADA to help secure the ledger and receive protocol-paid rewards for doing so. That is the next page.
It carries a voice. ADA holders can vote on how the network is governed and funded.

This already shows up off the chart

People already spend ADA in ordinary shops. Since March 2026 you can pay with it at 137 SPAR stores in Switzerland — scan a code from a wallet at the till. The store is paid in Swiss francs, so the grocer does not carry the price swings.^[5]

Markets have also given ADA a formal handle. In February 2026 CME Group listed regulated ADA futures — the same kind of contract desks use to hedge other assets.^[6] Some funds already hold ADA in a basket.^[7] A proposed U.S. spot ADA ETF was filed and later withdrawn by its sponsor; that is a firm changing plans, not a regulator rejecting the asset.^[8]

A partner network, Midnight, is being built so some of this can stay private. A UK bank, Monument, has announced plans to put tokenized deposits there. That work is not live yet.^[9]

None of that makes ADA a stable grocery currency. It does show the same two uses this page is about: spend it, or hold it as property. SPAR does the first and converts at the register. We do both — and when we keep it, that is the property frame, not a bet posted on a wall.

So why we accept ADA — and price some things lower in it

We accept it for the same reason we would accept any useful asset we are willing to hold. It has work. It is scarce on a published schedule. And some of our members already use the network.

We do two separate things. Keep them apart.

We accept ADA as payment for certain products and services. For some of them, the ADA price is lower than the dollar price — item by item, from our own margins. Where that is true, you will see both listed.
We reward delegators separately through the CarPool Discount Tier, unlocked when you delegate to our stake pool. That is a different mechanism, explained on the next page. It stacks with membership. It is not a second price for the same thing.

Neither is financial advice. Neither is a promise about ADA's price.

The practical path: set up a wallet → add some ADA → connect it → pay. The wallet guide walks each step.

The risks

ADA's value is volatile and uncertain. It can fall as well as rise. Past behavior predicts nothing.
Cardano is a maturing technology in a still-evolving regulatory landscape. What exists in shops and on exchanges is real. It is not a guarantee.
Only ever participate with what you understand and can comfortably afford — and never because anyone, including us, told you to.

Maybe the idea still appeals: a scarce, useful, community-governed asset, and putting some of it to work on a network built for the long game. If so, the last piece is the pool that makes delegation possible.

Cardano's monetary policy fixes the maximum supply at 45 billion ADA, all of it accounted for at launch: 31,112,484,646 distributed at genesis and 13,887,515,354 placed in the protocol reserve. Reserves are drawn down at roughly 0.3% per epoch, split between staking rewards and the treasury — so ADA enters circulation by scheduled release from an existing pot, not by minting. Circulating supply roughly 36.4–36.7 billion in mid-2026; public trackers vary, hence "roughly." See Cardano documentation (monetary policy) and cardano.org supply insights.
