Buying on Hydration means you never connect your wallet to this site. The swap below uses the same pool, if you prefer to stay here. Using it means you accept the Terms. Nothing here is financial advice.
Open Nova Wallet or SubWallet and tap Buy. Pay with a card, Apple Pay or Google Pay through Banxa, Mercuryo or Transak, and DOT lands in your wallet. Move it to Hydration, then swap here.
Watch the guideSwap stablecoins on Hydration straight into $WUD, in one transaction. No need to buy DOT first.
Watch the guideComing from Ethereum or Base? Buy $WUD right here with MetaMask. No Polkadot wallet needed.
- Connect MetaMask with the button below. It adds the Hydration network for you.
- Bring ETH, USDC or USDT over from Ethereum in the tab. It usually lands in 15 to 30 minutes, and your first deposit also pays your network fees, so you never need another token.
- Buy $WUD here. Choose ETH, USDT or USDC under Pay with, enter an amount and press Buy. MetaMask asks you to sign, and the fee comes out of your deposit.

Swaps run on Hydration and are signed in your own wallet, including MetaMask. Pay with DOT, HDX, ETH, USDT or USDC held on Hydration. DOT still on Asset Hub? Pick "DOT from Asset Hub" and Buy moves it over in the same flow. Everything goes through Hydration's own pools to the WUD/DOT pool in one transaction. Nothing on Hydration yet? See .
Watch the guideSwaps run in the WUD/DOT pool on Polkadot Asset Hub, using the DOT already in your wallet there. No bridging needed. Keep about 0.05 DOT on Asset Hub for network fees.

Cross-chain
Move DOT, USDT, USDC or $WUD between Polkadot Asset Hub and Hydration in one step. Every move is test-run on both chains before you sign.

When to move
- Just sent DOT to Asset Hub? Move it to Hydration here, or skip this: the Buy button on the Trade tab can move it and buy $WUD in one go.
- To Hydration to trade, provide liquidity or burn on the Burner Board. To Asset Hub to hold on Polkadot's main asset chain.
- Test-run first. Each move is simulated on both chains with your real balances. If anything would get stuck, the button stays off and nothing is sent.
- Your account stays open. The page always leaves the minimum each chain needs: about 0.1 DOT on Asset Hub, and 20,000 $WUD if you keep any $WUD on Hydration.
- Fees are paid in DOT on the chain you send from. Moving USDT, USDC or $WUD adds 0.1 DOT to carry it, and most of that comes back to you.
From Ethereum

How deposits work
- Your funds stay yours. They arrive at your own MetaMask address on Hydration, and this page checks that before you sign.
- ETH goes through Snowbridge, Polkadot's own Ethereum bridge: one signature.
- USDC and USDT go through Wormhole: an approval, then the deposit.
- Fees are paid in ETH on Ethereum, so keep a little ETH in MetaMask even when you send USDC or USDT.
- Your first deposit also pays your fees on Hydration, so you never need another token.
- You can close this page. The deposit keeps going, and this card picks it back up when you return.
Transfer
Send $WUD, DOT, stablecoins and more to another address on the same chain.

How transfers work
- Pick the chain your $WUD is on. Your balances are under the Trade tab. Most $WUD sits on Hydration.
- Same chain only. The recipient receives on the chain you send from. To switch chains, use the tab.
- Any Polkadot address works. Addresses starting with 1, 5 or 7 all point to the same account, so paste whatever the recipient gives you.
- On Hydration, an account needs at least 20,000 $WUD. Send 20,000 or more to a new holder, and keep 20,000 or more yourself, or send it all.
- On Asset Hub, the recipient must already hold a little DOT there, or the transfer is refused. Nothing is lost if it fails.
- Never send $WUD to an exchange deposit address. No exchange lists $WUD, and those tokens are unlikely to be recovered.

Buy DOT
Fastest: by card in your wallet. In Nova Wallet or SubWallet, tap Buy, pick DOT and pay with a card, Apple Pay or Google Pay. It arrives straight in your wallet, so you can skip step 3.
Or on an exchange. Coinbase, Kraken, Binance and most major exchanges sell DOT. $WUD itself is not on any centralized exchange, so DOT or a stablecoin is how you get in.

Withdraw DOT to your wallet
Copy your Polkadot address from your wallet and withdraw DOT to it, choosing the Polkadot network your exchange offers. Send a small test amount first, then the rest.
