What Is Hydration?
Hydration is Polkadot's main decentralised exchange. It is its own blockchain in the Polkadot network, built for trading, lending and stablecoins, and it is where $WUD trades most. It was known as HydraDX until its rebrand.
UpdatedThe Omnipool
Most exchanges split liquidity into thousands of separate pairs. Hydration's big idea is the Omnipool: one shared pool where every asset can trade against every other. Liquidity is concentrated instead of scattered, so trades get better prices and anyone can provide liquidity with a single token instead of a pair.
For you, that means you can swap almost any Polkadot token for almost any other in one step. On gavunwud.com, paying for $WUD with USDT or ETH routes through the Omnipool automatically.
What else Hydration does
- Money market. Lend and borrow against your assets.
- HOLLAR. Hydration's own dollar stablecoin.
- Fees in almost any token. You do not need HDX to use Hydration. You can pay network fees in DOT, USDT, USDC, ETH and many others, and change it from the Trade page.
- MetaMask support. Hydration runs an EVM, so Ethereum wallets work there too.
HDX
HDX is Hydration's native token. It pays for the network and is used in Hydration's governance. You can also use HDX to buy $WUD on gavunwud.com.
Why $WUD trades on Hydration
Hydration is where Polkadot's liquidity lives. $WUD's deepest market is on Hydration as asset 1000085, and it has more holders there than any other community token. $WUD also has a pool on Polkadot Asset Hub, where it is issued. Learn about Asset Hub.
