What is USDH? A Guide to the Two Stablecoins Behind the Ticker

You might think USDH is just another dollar-pegged token. But if you try to buy it on a major exchange today, you could end up with two completely different assets depending on where you look. That’s because "USDH" isn't one coin-it’s two distinct stablecoins sharing the same ticker, operating on different blockchains, and backed by fundamentally different things.

This confusion matters. One USDH is a crypto-backed asset on Solana, minted through decentralized loans. The other is a fiat-backed native asset on Hyperliquid, issued by Native Markets and backed by actual cash and US Treasuries. Mixing them up could mean holding an over-collateralized debt position when you expected a simple digital dollar, or vice versa. Let’s untangle the web so you know exactly what you’re buying.

The Big Split: Two Coins, One Name

Before diving into mechanics, let’s clarify the landscape. As of September 2026, the ticker USDH refers to:

• Hubble USDH (Solana): A decentralized, crypto-backed stablecoin issued by Hubble Protocol. It’s an SPL token on the Solana blockchain, backed by a basket of cryptocurrencies like SOL and ETH. Think of it as a cousin to DAI.
• Hyperliquid USDH (HyperEVM): A centralized, fiat-backed stablecoin issued by Native Markets. It lives on the Hyperliquid L1 network and is backed 1:1 by cash and short-term US Treasuries managed by institutional giants like BlackRock. Think of it as a competitor to USDC, but native to Hyperliquid.

Why does this matter? Because their risk profiles, yield mechanisms, and use cases are worlds apart. If you’re looking for a safe haven from crypto volatility, Hyperliquid USDH might fit. If you want to leverage your existing crypto holdings without selling, Hubble USDH is the tool. But don’t assume they’re interchangeable.

Hubble USDH: The Crypto-Backed Option on Solana

Hubble Protocol launched USDH as its core product on Solana. Unlike traditional banks that print money based on reserves, Hubble mints USDH through smart contracts. You can’t just "buy" new USDH directly from the protocol; you have to borrow it.

Here’s how it works: You deposit approved collateral-such as SOL, mSOL, BTC, ETH, RAY, SRM, or FTT-into Hubble’s vaults. In return, you can mint USDH against that collateral. Crucially, this is an over-collateralized system. For every $1 worth of USDH you mint, you must lock up at least $1.50 worth of crypto assets. This 150% buffer protects the peg if the value of your collateral crashes.

Because it’s backed by volatile assets, Hubble USDH carries liquidation risk. If the market dips sharply and your collateral ratio drops below the threshold, the protocol automatically sells your assets to repay the debt. It’s censorship-resistant and fully on-chain, but it requires active management if you’re using it as a borrowing instrument rather than just holding it in a wallet.

Hyperliquid USDH: The Fiat-Backed Native Asset

On the other side of the spectrum is USDH on Hyperliquid. This version emerged from a community-driven effort to create a stablecoin aligned specifically with the Hyperliquid ecosystem. Before USDH, about 95% of Hyperliquid’s $5.6 billion in stablecoin deposits were in USDC. The problem? Reserve yield from those USDC deposits flowed to Circle, not to Hyperliquid users.

Native Markets won a validator governance vote in September 2025 to issue USDH as the native liquidity asset for Hyperliquid’s HyperEVM layer. This USDH is backed 1:1 by cash and short-term US Treasury equivalents. The reserves are managed through a hybrid model: Stripe’s Bridge platform handles fiat tokenization, BlackRock manages off-chain cash portfolios, and Superstate issues on-chain tokens representing treasuries.

The key innovation here is yield sharing. Half of the interest earned on the reserve assets goes toward buying back and burning HYPE tokens, benefiting the Hyperliquid community. The other half funds ecosystem growth. This makes USDH more than just a payment rail; it’s a revenue-generating mechanism for the protocol itself.

Comparing Risk and Reward

Which USDH should you choose? It depends on your tolerance for complexity and your goals.

Hubble USDH appeals to DeFi power users who understand collateral ratios and liquidations. Its price has hovered around $0.99-$1.00, with minor deviations due to market liquidity. Since it’s backed by crypto, its stability relies on the health of the underlying assets. If Bitcoin and Ethereum crash simultaneously, the system remains solvent thanks to the 150% buffer, but individual borrowers face liquidation risks.

Hyperliquid USDH targets traders seeking a reliable, low-volatility asset within the Hyperliquid environment. Independent safety scores, such as those from usd.net, rate it around 51/100 with a "Caution" label. Why the caution? It’s young (launched late 2025), relies on centralized partners like BlackRock for reserves, and operates under evolving regulatory frameworks for tokenized treasuries. However, its 1:1 fiat backing generally offers lower volatility risk compared to crypto-backed models.

For context, early trading data showed Hyperliquid USDH maintaining a tight peg, with USDH/USDC pairs trading near 1.001 shortly after launch. This suggests strong initial confidence, but long-term viability will depend on sustained transparency from Native Markets and continued adoption within Hyperliquid’s order books.

How to Use Each USDH

If you’re interacting with Hubble USDH, you’ll likely be doing one of three things:

1. Borrowing: Deposit collateral to mint USDH, effectively leveraging your position.
2. Earning Yield: Hold USDH in Solana DeFi protocols or deposit it back into Hubble to earn liquidation rewards.
3. Transacting: Use it as a medium of exchange across Solana apps that support SPL tokens.

With Hyperliquid USDH, the use case is more focused:

1. Trading Settlement: Use it as the default quote asset for perpetual futures and spot markets on Hyperliquid.
2. Lending: Supply USDH to lending markets within the Hyperliquid ecosystem.
3. Community Rewards: Benefit indirectly from HYPE buybacks funded by reserve yields.

Developers integrating these tokens should note the technical differences. Hubble USDH is an SPL token, compatible with standard Solana wallets and SDKs. Hyperliquid USDH runs on HyperEVM, requiring EVM-compatible tools and interacting with Hyperliquid’s specific order book architecture.

Future Outlook and Regulatory Considerations

Both versions of USDH are actively maintained. Hubble’s documentation was updated as recently as September 2026, reflecting ongoing improvements to its liquidation engines. Hyperliquid’s USDH continues to gain traction as it replaces external stablecoins within its ecosystem, capturing value that previously leaked out to issuers like Circle.

Regulation remains a wildcard. Hyperliquid USDH’s reliance on tokenized treasuries places it at the forefront of the "RWA" (Real World Assets) trend. While partnerships with BlackRock add credibility, they also introduce counterparty risk and regulatory scrutiny. Hubble USDH avoids direct exposure to traditional finance regulations but faces the inherent risks of crypto market volatility.

As we move through 2026, watch for changes in collateral requirements for Hubble and further integration of yield-sharing mechanisms for Hyperliquid USDH. Both projects aim to solve the same problem-providing a stable dollar-but they take radically different paths to get there.
