# Hydration > Finance made efficient Hydration is a DeFi appchain on Polkadot that combines token trading, lending, and a native over-collateralized stablecoin in one protocol. Hydration is a DeFi appchain on Polkadot that consolidates trading, lending, and stablecoin issuance into a single protocol. Users can trade tokens through the Omnipool, borrow assets using crypto collateral via a money market based on Aave v3, and mint HOLLAR, an over-collateralized stablecoin. HDX token holders participate in on-chain governance and earn staking rewards from protocol revenue. - Type: Project - Sector: Finance - Status: Active - Founded: 2020-01-01 - Profile: https://thegrid.id/profiles/hydration ## Products - [Hydration](https://thegrid.id/profiles/hydration): Hydration is a decentralised exchange that combines all supported assets in a single Omnipool, enabling single-sided liquidity provision and reduced slippage. Users can trade through standard swaps, automated dollar-cost averaging orders, or OTC markets, and pay transaction fees using any supported asset. The appchain design ensures liquidations are executed at the start of every block, reducing MEV exploitation common on general-purpose chains. (Decentralised Exchange, Live, Main Product) - [Hydration Money Market](https://thegrid.id/profiles/hydration): Hydration Money Market is a decentralised lending protocol built on a modified Aave v3 architecture that allows users to supply crypto assets to earn interest and borrow against accepted collateral. Supported collateral includes DOT, ETH, USDT, USDC, tBTC, vDOT, and WBTC. Partial liquidations are executed automatically at the start of every block to restore health factors, reducing all-or-nothing liquidation risk. (Decentralised Borrowing & Lending, Live) ## Assets - [Hydration (HDX)](https://thegrid.id/profiles/hydration): HDX is the governance token of Hydration. It is used to vote on protocol referenda, earn staking rewards from protocol revenue, and incentivize liquidity provision. Stakers earn rewards from LP fees and treasury subsidies through a bonding curve that accelerates payouts for active governance participants. (Governance) - [HOLLAR (HOLLAR)](https://thegrid.id/profiles/hydration): HOLLAR is a decentralized stablecoin backed by crypto collateral on Hydration. It is used for trading, as collateral in DeFi, and as a stable store of value on the Hydration network. Unlike full liquidation models, HOLLAR uses partial liquidations executed at the start of every block to restore borrower health factors while preserving remaining collateral positions.
