DOT Token
DOT is Polkadot's native token, similar to BTC for Bitcoin or ETH for Ethereum. DOT has three main functions:
- Governance: DOT holders can vote network governance and propose changes to the protocol, including fees, token inflation, and code upgrades. Learn more on the governance page.
- Staking: DOT holders can lock their tokens to secure the network and get staking rewards for their commitment. Learn more on the staking page.
- Access secure computation: DOT is used to purchase Coretime and access secure computation and interoperability; and reserve parachain identifiers for rollups.
A portion of DOT inflation is diverted to the Treasury, which can fund Polkadot-related projects via OpenGov referenda.
See the chain state values page for more information about DOT total issuance, active and inactive issuance, deposits and more.
The Planck Unit
Section titled “The Planck Unit”The smallest unit of account balance on Polkadot SDK-based blockchains is Planck, named after the Planck Length. DOT equals 1010 Planck, while Kusama's KSM equals 1012 Planck.
| Unit | Decimal Places | Conversion to Planck | Conversion to DOT |
|---|---|---|---|
| Planck | 0 | 1 Planck | 0.0000000001 DOT |
| Microdot (uDOT) | 4 | 104 Planck | 0.0000010000 DOT |
| Millidot (mDOT) | 7 | 107 Planck | 0.0010000000 DOT |
| Dot (DOT) | 10 | 1010 Planck | 1.0000000000 DOT |
| Million (MDOT) | 16 | 1016 Planck | 1,000,000.00 DOT |
| Unit | Decimal Places | Conversion to Planck | Conversion to KSM |
|---|---|---|---|
| Planck | 0 | 1 Planck | 0.000000000001 KSM |
| Point | 3 | 103 Planck | 0.000000001000 KSM |
| MicroKSM (uKSM) | 6 | 106 Planck | 0.000001000000 KSM |
| MilliKSM (mKSM) | 9 | 109 Planck | 0.001000000000 KSM |
| KSM | 12 | 1012 Planck | 1.000000000000 KSM |
DOT Inflation
Section titled “DOT Inflation”Total supply
Section titled “Total supply”The current total supply is approximately 1.6 billion DOT, with a maximum supply capped at 2.1 billion DOT. You can check the latest value on the Subscan token supply dashboard, the Developer Interface Explorer, or on CoinGecko / CoinMarketCap.
New DOT is minted to reward validators and nominators who secure the network through staking, and to fund the Polkadot Treasury. The issuance model has evolved through OpenGov: Referendum 1710 (implemented January 2026) introduced a capped, stepped schedule in which inflation steps down every two years — 13.14% of the remaining gap to the 2.1 billion DOT cap every two years, with the first step on 14 March 2026 — so it declines as the circulating supply approaches the cap.
DOT is an inflationary token, with fixed annual expansion of the token supply of 120,000,000 DOT, of which 15% goes to the treasury and 85% to stakers.
It is essential to understand that the primary objective of inflation is to incentivize network participants through Nominated Proof of Stake (NPoS) and to grow the network through funding the on-chain treasury. The token inflation rate can be updated through on-chain governance based on thorough tokenomics research.
Below is a 25-year prediction of DOT gross annual inflation (red line) and DOT total issuance (blue line), assuming the current fixed inflation rate.
The total issuance takes into account the gross DOT inflation and thus does not consider tokens that are burned.
Net DOT inflation depends on treasury burns and coretime sales that are variables and thus cannot be predicted. Net inflation can be defined as follows:
Net Inflation = Gross fixed inflation - burned supply (treasury + coretime sales)Where Gross fixed inflation is the annual inflation of 120M DOT and the burned supply is the
annual burn supply due to treasury burns and coretime sale burns.
DOT and KSM Claims
Section titled “DOT and KSM Claims”DOT and KSM are not freely distributed. Obtain them via the claim process, Treasury, or the open market.
Obtaining Testnet Tokens
Section titled “Obtaining Testnet Tokens”Testnet tokens allow experimentation on Polkadot's features. Obtain testnet tokens on the official faucet. For faucet issues, use the support chat or create an issue.
Paseo mirrors Polkadot's runtime. Obtain PAS tokens here or via !drip <PASEO_ADDRESS> in the Matrix chatroom.
| Unit | Decimal Places | Conversion to Planck | Conversion to PAS |
|---|---|---|---|
| Planck | 0 | 1 Planck | 0.0000000001 PAS |
| Microdot (uPAS) | 4 | 104 Planck | 0.0000010000 PAS |
