About Polkadot
A network designed to coordinate multiple connected blockchains.
Polkadot launched in 2020 to coordinate a relay chain and connected application-specific chains.
Polkadot appears in this directory for research, not as an endorsement. Its interoperability network design should be judged through the documented network, supply, control, and failure model rather than through the DOT unit price alone.
How to read the DOT price
The displayed DOT reference is the latest available observation from Coinbase Exchange for DOT/USD. It belongs to that venue, quote asset, and timestamp; Polkadot has no single official global price.
An executable DOT order can differ after spread, depth, slippage, fees, payment method, and location. The market label above shows which currency or asset defines the observed price.
