What Is Polkadot (DOT)?

Polkadot is a blockchain project that focuses on creating a platform that other blockchain-based projects and applications can build on. Polkadot is a decentralized, nominated proof-of-stake (NPoS) blockchain with smart contract functionality, described as a layer-0 protocol that unites purpose-built blockchains.

DOT has a maximum supply cap of 2.1 billion tokens, set by governance on September 15, 2025 and activated on March 14, 2026 through an on-chain governance vote. The current circulating supply is approximately 1.7 billion DOT (per CoinGecko). Annual issuance was cut by 53.6% to roughly 57 million DOT per year, lowering inflation from about 7–10% to roughly 3.1%, with issuance stepping down further over time.

DOT serves three purposes: staking for network operations and security, participating in on-chain governance, and bonding tokens to connect parachains.

Who created Polkadot?

Polkadot was founded by Gavin Wood, a co-founder of Ethereum and creator of the Solidity programming language, alongside co-founders Peter Czaban and Robert Habermeier. Its mainnet, also known as the Relay Chain, went live on May 26, 2020, enabling DOT token transfers and network governance. In August 2020, DOT tokens underwent a redenomination. The nonprofit Web3 Foundation, based in Zug, Switzerland, managed the network during its early phase, while the Polkadot SDK and other core technology components are developed by Parity Technologies.

What Makes Polkadot Unique?

Most blockchains function autonomously and are not connected to any others. Popular cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH), and Cardano (ADA) each have their own blockchain. As they don’t communicate with each other, decentralized applications (dApps) developed on Ethereum and Cardano cannot work together.

This is where Polkadot comes in. As a multichain network, it can connect multiple blockchains. Developers utilizing Polkadot can construct their own blockchains that can communicate with every other blockchain in the Polkadot network.

At the center of Polkadot sits the Relay Chain, a central blockchain that connects all other participating blockchains together. Parachains are user-created blockchains that hook into the Relay Chain and inherit shared security. Solochains are blockchains built with the Polkadot SDK that function independently. Interoperability across the network is created through a common standard of data exchange called XCM.

Interoperability creates new opportunities for Polkadot’s blockchains. For example, assume that one blockchain allows the purchase of tokenized stock. This blockchain could access the most recent stock price information from an independent blockchain.

Developers also benefit from Polkadot’s handling of transaction validation and network security. The network’s relay chain processes the transactions. This frees developers to concentrate solely on blockchain initiatives, as they won’t have to worry about creating a safe method for validating transactions.

How to buy Polkadot?

DOT can be bought or sold on Coinbase and other exchanges that list DOT. DOT is available on major cryptocurrency exchanges; check that the venue lists DOT and supports your region.

DOT is used for staking and governance. Unstaking starts a 28-day unbonding period, and leaving a nomination pool unbonds too. Only after it ends can you send or sell the DOT. An account that drops below the minimum of 0.01 DOT is closed and the rest is removed; either send your whole balance or leave at least 0.01 DOT behind.

As with any cryptocurrency, DOT is subject to price volatility, changing regulatory policies, and technical risks. Nothing here should be taken as a guarantee of future performance.

Funding & history

Polkadot held an initial coin offering (ICO) in October 2017, raising over $144.3 million. A private token sale in 2019 raised an additional $43 million. Shortly after the ICO, a vulnerability in the multi-signature wallets developed by Parity Technologies led to the freezing of approximately $150 million worth of Ethereum. Over 500 wallets were impacted, including Polkadot’s wallet, which held a significant portion of the $144.3 million raised during its ICO.

Institutional access & regulation

On March 6, 2026, the 21Shares Polkadot Trust (TDOT) launched on Nasdaq as the first US-listed spot Polkadot exchange-traded product, holding physical DOT with Coinbase as custodian. The fund charges a 0.30% management fee, reduced to 0.09% through October 2026. On March 19, 2026, an SEC/CFTC interpretation named Polkadot (DOT) as a digital commodity.
