What is USDH? The Stablecoin Behind Hyperliquid Trading
USDH is Hyperliquid's native stablecoin. Here's what it is, how it relates to USDC, and why Hyperliquid uses it.
Every exchange needs a dollar
When you trade on any platform — stocks, crypto, prediction markets — there needs to be some base currency that everything is priced in. On Binance, that’s USDT. On Coinbase, it’s USD. On Hyperliquid, it’s USDH.
USDH is a stablecoin — a crypto token designed to always be worth $1. But it’s specifically the stablecoin that lives natively on Hyperliquid’s L1 chain. Understanding USDH takes about two minutes, and it’ll save you confusion later.
USDH vs USDC: what’s the difference?
USDC is the stablecoin you probably already know. It’s issued by Circle, backed by US dollars and Treasury bills, and lives on multiple blockchains (Ethereum, Arbitrum, Solana, etc.). It’s one of the most trusted stablecoins in crypto.
USDH is Hyperliquid’s native representation of that dollar value on its own L1. When you deposit USDC into Hyperliquid via the bridge, your balance on Hyperliquid is denominated in what functions as USDH.
Think of it like exchanging dollars for chips at a casino — except the “chips” are always worth exactly $1, and you can cash them back to USDC whenever you want. The conversion is 1:1, and withdrawals are permissionless (no casino manager can refuse to cash you out).
Why does Hyperliquid need its own stablecoin?
Good question. A few reasons:
Speed
Hyperliquid’s L1 settles transactions in under a second. If every trade had to interact with USDC’s smart contract on Ethereum or Arbitrum, that speed would be impossible. USDH is native to the chain, so transfers and settlements happen at L1 speed.
Unified collateral
Your USDH balance backs everything you do on Hyperliquid: perp positions, spot trades, and prediction markets. This shared margin model only works cleanly if there’s one base asset the entire engine understands natively.
Composability on HyperEVM
Hyperliquid has an EVM-compatible layer (HyperEVM) where developers can deploy smart contracts. USDH serves as the native stablecoin for this ecosystem too — it’s the base pair for DeFi protocols, lending markets, and anything else built on HyperEVM.
Is USDH safe?
The safety of USDH is directly tied to the safety of the USDC backing it. Since USDH is backed 1:1 by USDC deposits, the risk profile is essentially the same as holding USDC — which is to say, it depends on your trust in Circle (the USDC issuer) and the Hyperliquid bridge infrastructure.
The bridge is the key trust assumption. You’re trusting that:
- The bridge correctly locks your USDC on Arbitrum
- The corresponding USDH is minted correctly on Hyperliquid’s L1
- When you withdraw, the process works in reverse
Hyperliquid’s bridge has processed billions of dollars without incident, but it’s worth understanding that this trust assumption exists. It’s the same type of bridge risk that applies to any L2 or alt-L1 in crypto.
How USDH works in practice
As a user, you mostly don’t need to think about USDH. Here’s your actual experience:
- You deposit USDC from Arbitrum into Hyperliquid
- Your Hyperliquid balance shows up in dollar terms
- You trade — perps, spot, prediction markets — all denominated in dollars
- When you withdraw, you get USDC back on Arbitrum
The USDH ↔ USDC conversion happens automatically behind the scenes. You never need to “swap” between them or manage two separate balances.
On HyperEVM, USDH has a token contract address (0xb88339CB7199b77E23DB6E890353E22632Ba630f — that’s actually the USDC representation on HyperEVM) that DeFi protocols interact with. But again, as a regular user and trader, you don’t need to deal with this directly.
USDH vs USDT vs DAI: a quick comparison
| Feature | USDH | USDC | USDT | DAI |
|---|---|---|---|---|
| Peg | $1 | $1 | $1 | $1 |
| Backing | USDC (1:1) | USD + T-bills | USD + commercial paper | Crypto collateral |
| Native chain | Hyperliquid | Ethereum | Ethereum | Ethereum |
| Used for | Hyperliquid trading | Broad DeFi | Broad DeFi | DeFi |
| Trading fees | Zero (on prediction markets) | Varies by platform | Varies by platform | Varies by platform |
The important takeaway: USDH inherits USDC’s stability while being optimized for speed on Hyperliquid. It’s not trying to compete with USDC across all of crypto — it’s the dollar unit for Hyperliquid’s ecosystem specifically.
What about USDT0?
You might also encounter USDT0 on HyperEVM. This is a bridged version of USDT (Tether) that arrives via the LayerZero bridge. It’s a separate stablecoin from USDH, available for DeFi applications on HyperEVM. For core Hyperliquid trading (perps, spot, prediction markets), your balance is USDH — not USDT0.
The bottom line
USDH is just “your dollars on Hyperliquid.” It’s backed by USDC, it’s always worth $1, and it powers everything you do on the platform. You deposit USDC, trade with USDH, and withdraw back to USDC. The abstraction is clean enough that most traders never even think about it — which is exactly how a stablecoin should work.
