Markets & services
Sections ↑Hydration combines automated crypto exchange, lending and a collateral-backed stablecoin on a Polkadot appchain. Trading occurs against protocol liquidity rather than a centralised customer order book. Its Omnipool brings multiple assets into a shared system, while separate pools serve correlated assets and individually created markets. These mechanisms sit alongside tools for individual wallets, projects and DAO treasuries.[1]
Trading services and execution controls
| Service | How it works | Material boundary |
|---|---|---|
| Omnipool | A user can supply one supported asset; H2O acts as the internal hub linking asset pools. | Single-asset entry does not eliminate exposure to other pool assets or price changes.Source 21 |
| Stablepools and isolated pools | Stablepools serve correlated assets; isolated pools support separate markets and token launches. | Pool composition and available liquidity determine which route can execute.Source 1 |
| Instant swap | Specify the amount to spend or the amount to receive, adjust slippage and sign through the wallet. | An unsigned quote is not a completed transaction.Source 4 |
| Protocol OTC | The EVM-wallet guide explicitly supports placing OTC orders. | This establishes a protocol feature, without a staffed institutional dealing desk or public minimum ticket.Source 9 |
Split Trade breaks a large instruction into smaller executions. The product documentation targets an estimated slippage below 0.1% per component, while the quick-start guide describes offering the feature above 0.15% estimated price impact and execution over less than three hours. These are interface estimates with different purposes, not a guaranteed fill price or completion time.[4][6]
The full DCA tool accepts the amount per execution, total budget, destination asset and interval. Advanced settings use block intervals rather than an approximate number of hours. The customer signs the schedule once; the protocol schedules later executions. Open schedules can run in parallel and can be terminated for their remaining amount. Closing the browser is not the documented termination action.[5][6]
Fees & commercial terms
Sections ↑Published protocol and pool charges
| Action | Published charge | Charging scope |
|---|---|---|
| Network transaction | Approximately 1.60 HDX or more | Applies to network actions.Source 3 |
| Omnipool swap | Asset fee 0.25%–5%; protocol fee 0.05%–0.10% | Dynamic; asset fee in output token, protocol fee in H2O.Source 3 |
| Omnipool liquidity exit | 0.01%–1% | Dynamic liquidity-withdrawal fee.Source 3 |
| Isolated-pool swap | 0.3% | Taken in the purchased asset.Source 3 |
| Stablepool swap or exit | 0.04% headline | Pool-specific trade fee; withdrawal fee matches it.Source 3 |
| Liquidity bootstrapping pool | Variable | Creator sets repayment and subsequent swap charges.Source 3 |
| Protocol OTC trade | 0% trading fee | Network transaction cost remains separate.Source 3 |
At 0.04%, a 10,000-unit fee basis produces a 4-unit charge, excluding price impact and network costs. The stablepool’s actual configured rate governs.[3]
Transaction fees normally use an Omnipool asset; the first received asset becomes the default. The fee guide restricts MetaMask 0x-address fee payment to WETH (MRL). Confirm the live fee asset before signing.[3]
Borrowing adds variable interest tied to the selected lending market. The HOLLAR page states 5% annually in one passage and 5.12% in its minting instructions without clearly reconciling the rate labels. Neither is presented here as a fixed current borrowing quote. The position dashboard and its stated annual-rate convention are needed before estimating a holding cost.[17][18]
Deposits, withdrawals & operational limits
Sections ↑Moving assets into and out of Hydration
| Route or balance | Published process | What remains distinct |
|---|---|---|
| Polkadot ecosystem | Choose source chain, destination chain, asset, amount and receiving address, then sign the transfer. | The receiving-chain fee balance and supported route matter; a token symbol alone is insufficient.Source 8 |
| Ethereum via Wormhole | Bridge representation is minted on Moonbeam before onward transfer to Hydration. | Requires appropriate Ethereum and Polkadot wallets and ETH for source-chain fees.Source 7 |
| Ethereum via Snowbridge | Assets are represented on Asset Hub before onward transfer to Hydration. | The interface can offer different versions of the same underlying asset; review the actual representation.Source 7 |
| Ordinary wallet balance | Cross-chain and bridge mechanisms also transport assets away from Hydration. | A transfer out differs from removing liquidity or repaying a collateralised loan.Source 4 |
For a farmed liquidity position, the removal guide separates two actions: exit the farm and confirm that transaction, then remove liquidity and confirm again. Stopping farming rewards therefore does not itself return the underlying assets to a free wallet balance. The pool’s withdrawal charge and any active controls still apply.[23]
Lending deposits have their own withdrawal action under the supplied-assets dashboard. The guide shows a signed withdrawal but does not establish a universal settlement-time guarantee. Where assets support a loan, borrowing obligations and the position’s health must be resolved before treating the full displayed supply as freely transferable.[19][20]
GIGAHDX exit converts the position into HDX that remains transfer-locked for at least 28 days. Prior conviction votes can extend the lock; collateral supporting HOLLAR debt can reduce the amount available to unstake. Cancelling a pending unstake returns it to staking and loses the elapsed lock progress.[24]
The retrieved funding guides describe crypto movement, not a Hydration bank account or a fiat cash-out service. Dollar values shown in borrowing or homepage statistics are valuations, not evidence of a US-dollar deposit balance. Network transfer charges, bridge execution and later token conversion are separate stages.[7][8]
Custody & security
Sections ↑Wallet ownership and a protocol position are different forms of control. A wallet signs the initial transaction, but assets supplied to a pool follow its accounting rules until withdrawn. Omnipool liquidity can lose value relative to simply holding the original token; the comparison depends on price divergence against H2O and the asset’s pool weight. A single-token deposit is not a promise of returning the original quantity.[22]
The security documentation describes asset-level liquidity caps, oracle comparisons and a limit on trading more than 50% of an asset’s liquidity in one block. It also says liquidity additions and removals pause when the spot/oracle discrepancy exceeds 1%. These controls can restrict an otherwise valid exit during stressed conditions.[13]
HDX holders propose and vote on protocol decisions. The Technical Committee can whitelist urgent referenda for a faster track and temporarily pause selected asset functions. This gives the system an emergency intervention mechanism; the decentralised model should not be described as immutable or incapable of restricting trading.[14]
Hydration cites a September 2022 Runtime Verification audit of the Omnipool implementation and a March 2022 BlockScience economic review. Those dated and scoped reviews do not establish that every current component, bridge or later upgrade has the same audit coverage.[13]
Immunefi’s Hydration programme, updated 17 July 2026, lists a USD 222,222 maximum reward while older descriptive wording on the same page mentions a different cap. It pays qualifying security researchers in HDX under the programme’s scope. It is not customer deposit insurance, a reserve audit or an entitlement to compensation after a trading loss.[16]
The mobile-wallet guide places recovery responsibility on the holder’s mnemonic phrase and PIN. A protocol help channel cannot be assumed to reconstruct a lost signing key. The Ledger guide instead describes signing with the Universal Polkadot application through Talisman or SubWallet; hardware signing does not change the economic exposure of an approved pool or loan transaction.[10][12]
Access & eligibility
Sections ↑Published access instructions start with a compatible wallet. Desktop examples include Talisman, SubWallet and Nova Spektr; the mobile guide uses Nova Wallet. These are software-access routes, not a verified legal eligibility matrix. The retrieved documentation did not establish a complete minimum-age rule, residency list or set of prohibited jurisdictions for the public interface.[11][10]
Connecting an EVM wallet involves choosing the EVM option, selecting the account and accepting the Hydration network. That connection does not by itself approve a swap or move funds. The available guides do not establish identical alerts, saved preferences or transaction controls across every mobile browser, extension and hardware-wallet combination.[9]
DAO treasury activity has additional protocol requirements. Omnipool listings require a governance decision, and eligibility criteria do not guarantee approval. The listing guide limits an account’s liquidity addition or removal to 5% of that token’s pool liquidity per block, requiring larger changes in increments. A project’s ability to create an isolated market should not be confused with acceptance into the shared Omnipool.[33]
Support & complaints
Sections ↑Published assistance and disclosure routes
| Need | Official route | Scope |
|---|---|---|
| General contact | [email protected] | Listed on the current Hydration homepage; response hours are not published there.Source 2 |
| Wallet or Ledger difficulty | Discord or Telegram through official Hydration links | The Ledger guide refers unresolved issues to these community channels.Source 12 |
| Security vulnerability | [email protected] | Responsible disclosure address in the official node repository.Source 29 |
| Developer integration issue | Galactic Council SDK repository issue tracker | For SDK behaviour; not an order-cancellation desk.Source 15 |
A paused asset or an outstanding DCA schedule requires its relevant protocol action and state. The documentation describes targeted pauses and signed termination; sending a support message is not an alternative execution mechanism. No staffed emergency dealing service, guaranteed response time or formal compensation-based complaint route was established.[14][5]
Authorisations & registrations
Sections ↑The inspected public material did not establish a specific financial authorisation, regulated customer counterparty or statutory compensation scheme for using Hydration’s interface. OpenGov authority concerns protocol decisions. It should not be presented as a financial regulator’s licence, and wallet-based access alone does not determine which laws apply to a user.[14]
The SDK credits Intergalactic, Limited (GIB), while documentation footers use Intergalactic, Inc. The retrieved material did not reconcile those labels into a verified contracting-company chain. No customer entity, incorporation number, regulator identifier or permission scope is inferred solely from a software copyright notice.[15][1]
Protocol & operating identity
Sections ↑The official node repository identifies Hydration as formerly HydraDX. This profile treats those names as one protocol identity. Its open development repositories, protocol governance and public interface are related aspects of the service, rather than evidence of several separately licensed exchanges.[29]
On 20 October 2026 the homepage displayed approximately USD 59.4 million in total capital allocated, USD 3.1 million in total yield earned, USD 3.2 million in protocol revenue generated and 13.1 million HOLLAR issued. Those labels do not measure daily trading turnover or active customers, and the page does not give a common reporting period for a peer comparison.[2]
A liquidity-rewards page still advertises a campaign ending in December 2025. Its headline rates are not current October 2026 offers; trading-fee income and a presently available farm campaign must be assessed separately.[32]

Additional services & account tools
Sections ↑Lending, strategy tokens and governance staking
| Product | Return or exposure mechanism | Exit and risk conditions |
|---|---|---|
| Lending | Supply approved assets; borrower interest contributes to supplier returns. | Rates respond to supply and demand. Collateral ratios, liquidation thresholds and penalties are market-specific.Source 18 |
| HOLLAR | Mint a stablecoin targeting USD 1 against approved crypto collateral. | Debt accrues interest. Repayment releases collateral; partial liquidation and peg deviation remain possible.Source 17 |
| GIGADOT | Combines vDOT staking exposure, aDOT lending interest, pool fees and incentives when available. | Represents a composite pool position. Borrowing against it adds debt and liquidation exposure.Source 30 |
| GIGAETH | Combines wstETH, aETH and underlying pool income, with any additional incentives. | The guide describes exit by swapping; market liquidity, price impact and any collateral commitment remain relevant.Source 31 |
| GIGAHDX | HDX deposited into a governance-linked pool earns protocol revenue through a changing conversion rate. | Governance and borrowing features are separate from proof-of-stake validator delegation. The exit lock is described above.Source 24 |
Lending users can inspect the market’s maximum loan-to-value ratio, liquidation threshold and penalty before signing. The borrowing guide distinguishes adding collateral from repaying debt. For illustration, a loan of 600 units against collateral worth 1,200 units has 50% loan-to-value; this arithmetic does not establish that a particular market permits that ratio or that the position cannot be liquidated later.[20]
The lending design prioritises protocol liquidations at the start of blocks and can recycle the resulting surplus through governance. This changes execution incentives; it does not remove the borrower’s liquidation penalty or make collateral values stable. E-Mode can use different parameters for correlated assets, so its borrowing capacity should not be applied to an ordinary market.[18]
GIGAHDX voting rewards require qualifying Aye or Nay votes with conviction. Split, Abstain and no-conviction votes do not earn that additional reward. Claiming compounds the reward into the position, while passive yield appears through its conversion value. An estimated voting APR is not an immediately withdrawable cash bonus.[25]
Existing legacy staking positions have a separate route at staking-old, with migration presented in the GIGAHDX interface. New staking uses the current GIGAHDX route. A legacy bookmark should therefore not be used to assume that old reward or exit conditions apply to a new position.[24]
GIGADOT’s published approximation combines half the vDOT yield, half the aDOT yield, pool fees and incentives. GIGAETH uses a similar composition for ETH exposures. The component rates cannot all be added at full weight, and illustrative APR figures should not be relabelled as a guaranteed compounded portfolio APY.[30][31]
Yield DCA uses appreciation in Bifrost’s vDOT to fund periodic purchases of another supported asset. The documentation describes execution at least every 24 hours depending on order size. Its older average-yield illustration is not a current rate commitment. The staking token, the underlying DOT exposure and the assets purchased by the schedule remain separate holdings.[27]
Referral rewards come from Omnipool asset fees and accumulate in HDX for claiming. The referrer’s tier and actual trading activity affect the amount; the programme has five tiers. HDX asset fees have a separate staking allocation. This is fee-sharing income, not a deposit-matching bonus with a fixed cash value or a promise that referral earnings offset trading costs.[26]
The bond documentation describes HDX claims with a maturity date, issued through governance to obtain assets for protocol-owned liquidity. Distribution can use a priced sale or an OTC offer, and the claims can trade before maturity. This describes the mechanism; it does not establish that a particular bond sale is open, that an exit buyer exists, or that every HOLLAR-labelled product has identical terms.[28]
The current Galactic SDK provides trade routing, pool queries and cross-chain tools; its older Polkadot API toolkit is maintained separately as sdk-legacy. These are developer interfaces, without a published exchange-style read/trade/withdraw API-key permission matrix in the retrieved README. A wallet-connected integration must still distinguish reading data from signing transactions.[15]
The official site links a blockchain explorer, but the reviewed public material did not establish a complete tax-ready statement, cost-basis export or post-disconnection reporting service. Transaction hashes and position events provide evidence of activity; they should not be assumed to contain the entire fiat valuation or acquisition history needed for a person’s own records.[2]
