What Is Cardano?

Cardano is a blockchain network for payments and smart contracts, the self-running programs that power lending apps, exchanges and other crypto services. Its coin is ADA, used to pay transaction fees, earn staking rewards and vote on how the network changes.

Charles Hoskinson, one of Ethereum's co-founders, started Cardano through his company Input Output Global (IOG). The network went live in September 2017. Two other groups share the work: the Cardano Foundation, a Swiss nonprofit, and EMURGO, a company focused on business adoption.

Cardano's main claim is its method. The project says it builds from peer-reviewed academic research, with parts of the protocol first described in papers starting in 2015. Supporters see that as a careful approach. Critics point out that it has made Cardano slower than rivals to ship features like smart contracts, which arrived in 2021.

How Cardano Works

Cardano runs on proof of stake, a system where coin holders, instead of miners, secure the network. Its version is called Ouroboros. Time is split into five-day "epochs," and the protocol picks stake pool operators at random, weighted by how much ADA is delegated to them, to produce each block.

Anyone holding ADA can delegate it to a stake pool without locking it up or handing it over. The ADA stays in your wallet and you can spend it anytime. Grayscale's ETF filing notes that rewards typically start 15 to 20 days after you delegate, and that Cardano does not use slashing, the penalty some networks impose by destroying part of a validator's stake.

ADA has a fixed maximum of 45 billion coins. The portion not yet in circulation sits in a reserve, and a small share is released each epoch to pay staking rewards. Part of each epoch's rewards flows to a community treasury.

Since upgrades in September 2024 and January 2025, ADA holders govern the network on-chain. They elect delegated representatives (DReps) who vote on protocol changes and treasury spending under a written constitution.

What People Use It For

The most common use of ADA is staking. Holders delegate to a stake pool to earn rewards while keeping full control of their coins, which makes ADA a popular holding for people who want yield without lockups.

ADA also pays for transactions and smart contracts on Cardano. The network hosts decentralized exchanges, lending apps and stablecoins, though its app activity is far smaller. DefiLlama counted about $54 million locked in Cardano apps on Nov. 2, 2026, against about $44.5 billion on Ethereum and $5.5 billion on Solana, according to its chain rankings.

Governance is a newer use. ADA holders can vote directly or delegate their vote to a DRep on treasury proposals, which fund development, marketing and other projects.

Cardano also supports native tokens, which can be created without writing a smart contract. Projects use them for stablecoins, NFTs and their own tokens.

Risks To Know

Ownership is fairly concentrated. As of October 2025, the 100 largest ADA wallets held about 29% of circulating supply, according to Grayscale's filing.

The network has had serious technical problems. On Nov. 21, 2025, a malformed delegation transaction exploited a dormant bug in some recent node versions and split the chain in two. Node operators and exchanges upgraded to patched software, and the network was back on a single chain within about 14.5 hours with no funds stolen, according to Intersect's incident summary.

The SEC named ADA as a security in its 2023 lawsuits against Binance, Coinbase and Kraken. All three cases were dismissed in 2025, but the label shaped which platforms listed ADA during that period.

There is no US spot ADA ETF. Grayscale filed for one in August 2025 and withdrew the filing in August 2026, saying it no longer planned to proceed.

Key-person risk is real, too. Hoskinson remains Cardano's most visible figure, and Grayscale lists his departure as a risk to ADA's price.

How To Buy Cardano

ADA is listed on most major US exchanges, including Coinbase, Kraken, Bitstamp, Binance.US, Crypto.com and OKX. Bitstamp's US service stops taking new deposits and purchases on Feb. 1, 2027. International buyers can also use Bitget, MEXC and Gate.

Many exchanges let you stake ADA directly, though they keep a cut of the rewards. If you want to delegate yourself, you can move ADA to a Cardano wallet and pick a stake pool.

Cardano And Your Taxes

The IRS treats ADA as property, so selling, trading or spending it creates a capital gain or loss. Holding more than a year qualifies you for long-term rates.

Staking rewards count as ordinary income at their fair market value when you gain control of them, which on Cardano means each epoch they're paid. That creates many small income entries over a year, so a crypto tax tool helps. Read more on how crypto taxes work.

FAQ

Is Cardano A Good Investment?

That's a call only you can make. Points to weigh include ADA's fixed 45 billion supply, staking without lockups and on-chain governance. On the other side, Cardano's app activity trails bigger networks, the November 2025 chain split showed software risk, and no US spot ETF exists. For background, see how to invest in Cardano.

What Is The Max Supply Of Cardano?

ADA's maximum supply is fixed at 45 billion. Coins not yet in circulation sit in a protocol reserve, and a small portion is released every five-day epoch to fund staking rewards and the treasury. As the reserve shrinks, new issuance slows, and fees make up a growing share of rewards.

Who Created Cardano?

Charles Hoskinson, a co-founder of Ethereum, created Cardano through Input Output Global, the company he leads. The Cardano Foundation in Switzerland and EMURGO also supported the 2017 launch. Today the network is governed on-chain by ADA holders and their elected representatives.

Can I Stake Cardano?

Yes. You can delegate ADA to a stake pool from your own wallet and keep the coins liquid, since Cardano has no lockup and no slashing. Rewards start after about 15 to 20 days. Many exchanges also offer ADA staking, though they keep part of the rewards and state availability varies.

Can I Buy Cardano In An IRA?

Not through a US spot ETF, because none exists after Grayscale withdrew its filing in August 2026. Some crypto IRA providers let you hold ADA directly in a self-directed account. Compare platform fees and whether the provider supports staking. See our list of crypto IRA providers.

Where Can I Buy Cardano In The US?

Coinbase, Kraken, Bitstamp, Binance.US, Crypto.com and OKX all list ADA for US customers. Check that the exchange operates in your state, and whether it offers staking where you live, before you sign up. Fees and spreads vary from one exchange to the next, so compare the full cost in the table above before you buy. Our ranking of the best crypto exchanges covers each platform in more detail.
