Hydration, formerly HydraDX, is a Layer 1 DeFi parachain on Polkadot built around the Omnipool, a single shared pool that all listed assets trade against. Its native token is HDX.
Hydration is a DeFi-focused parachain on Polkadot that pools liquidity into a single Omnipool, so assets trade against one shared pool rather than many separate trading pairs, with the HDX token used for governance and protocol incentives. Here is how it works and what it is used for, not the price.

Hydration runs as a parachain built with the Polkadot SDK, so it does not run its own validator set. Instead it produces blocks as a parachain and inherits security from the Polkadot relay chain, which uses Nominated Proof of Stake. The chain rebranded from HydraDX to Hydration in 2024 after a community referendum, and blocks settle in roughly six seconds.

Omnipool
A single liquidity pool that every listed asset trades against, instead of separate pools for each pair, which concentrates liquidity in one place.
Parachain model
Hydration is a Polkadot parachain, so it shares the relay chain security and can connect with other parachains rather than running an isolated validator set.
HDX governance
Holding HDX grants voting power in the Hydration DAO, which decides protocol changes including whether an asset is added to the Omnipool through public referenda.
Cross-chain liquidity
Because it sits in the Polkadot ecosystem, Hydration can route assets and liquidity between connected chains through cross-chain messaging.
