Most stablecoins are tourists. They're issued somewhere else, custodied somewhere else, and they treat the chain they land on as a venue. The yield they generate flows back to a parent company that doesn't know your validators' names. USDH was built on a different premise: that the largest perp DEX in DeFi shouldn't have to rent its own settlement currency.
USDH is Hyperliquid's native stablecoin. It's pegged 1:1 to the dollar, fully backed by US Treasuries, cash, and cash equivalents, and live across both HyperCore and HyperEVM. The asset is designed by Native Markets and issued by Bridge, a US-regulated stablecoin issuer. Reserves are managed by BlackRock and Superstate, with custody at JPMorgan Chase and Fireblocks.
If you trade on Hyperliquid, USDH is worth understanding. The fee structure alone changes the math on active trading. And the best way to get USDH on Hyperliquid is with Across with no fees.
Why Hyperliquid Built Its Own Stablecoin
Before USDH, Hyperliquid's liquidity was overwhelmingly USDC. By the time the USDH proposal went to validator vote in September 2025, roughly 95% of the platform's stablecoin deposits, about $5.6 billion, were sitting in Circle's stablecoin (source).
That worked. But it also leaked value. The reserves backing all that USDC were earning yield on US Treasuries, and that yield flowed to Circle and its distribution partners, not to the protocol that created the demand. Estimates put the foregone revenue between $150 million and $220 million per year (source).
The other concern was sovereignty. A platform marketing itself as decentralized perp infrastructure was settling almost entirely in a permissioned asset that can be frozen at the issuer level. For a chain whose pitch is on-chain, transparent, self-custodial trading, that was a structural mismatch worth fixing.
So Hyperliquid reserved the USDH ticker and ran one of the more interesting governance experiments DeFi has produced: a competitive bid for the right to issue the chain's stablecoin, decided by an on-chain validator vote.
The Bid That Won
Native Markets won the validator vote in September 2025, beating Paxos, Ethena, Frax, Sky, and Agora. Several of those bids offered more generous revenue splits, 95% to 100% of reserve yield in some cases against Native Markets' 50%, and Native Markets still won (source).
The argument for Native Markets was alignment. Their team draws on alumni from BlackRock, Uniswap, Stripe, Circle, and Ramp (source), assembled specifically to launch a Hyperliquid-native stablecoin. Cofounders include Max Fiege, an early Hyperliquid ecosystem investor; Anish Agnihotri, a blockchain researcher; and MC Lader, the former president and COO of Uniswap Labs. The validators bet that proximity to the ecosystem mattered more than maximum revenue extraction.
The headline result is the one Native Markets leads with: 100% of USDH reserve yield goes back to the Hyperliquid ecosystem (source). The split is 50% to the Hyperliquid Assistance Fund, which programmatically converts fees into HYPE tokens, and 50% to USDH growth and ecosystem builders. Native Markets has also staked 1 million HYPE as a long-term commitment to the ecosystem.
The Trader's Edge: Aligned Quote Asset Benefits
The reason most Hyperliquid traders care about USDH isn't the philosophy. It's the fee schedule.
USDH is the first and only Aligned Quote Asset (AQA) on Hyperliquid, which earns three concrete advantages on USDH-quoted markets (source):
20% lower taker fees on USDH-quoted markets
50% higher maker rebates for providing liquidity
20% volume contribution amplification, so USDH trading volume counts more toward your overall fee tier and gets you to lower rates faster
For an active trader, those numbers compound fast. A 20% reduction on every taker fee across a high-frequency strategy is the kind of edge worth restructuring a workflow around. A 50% bump on maker rebates rewards anyone providing liquidity. And the volume amplification toward fee tiers means your USDH activity carries more weight when Hyperliquid calculates which discount band you sit in.
This is the design intent. USDH isn't another stablecoin sitting alongside USDC. It's the asset Hyperliquid wants traders to use, and the AQA framework is how the protocol expresses that preference.
USDH vs USDC on Hyperliquid
The practical question for most users is which one to hold. Both are 1:1 USD-backed. Both are supported on Hyperliquid as quote assets. Native USDC will continue to be supported alongside USDH, so the migration isn't forced (source).
The differences come down to economics and alignment. USDH-quoted markets give you 20% lower taker fees, 50% higher maker rebates, and faster fee-tier progression. The reserve yield USDH generates flows back to the Hyperliquid ecosystem rather than to an external issuer. USDH also offers a free 1:1 USDC-to-USDH bridge through Across and a direct bank-to-Hyperliquid onramp through Native Markets' dashboard.
USDC has wider distribution outside Hyperliquid and Circle's regulatory track record. For traders whose activity is mostly inside Hyperliquid, the math points toward USDH. For users who need stablecoin liquidity across a wide set of chains and apps, USDC remains useful.
HyperCore and HyperEVM: Where USDH Lives
Hyperliquid's architecture is two virtual machines unified under a single consensus layer. USDH is live on both.
HyperCore is the Rust-based trading engine. It's where the on-chain order book matches, margin gets calculated, and trades settle. When you bridge USDH to HyperCore, it lands directly in your Hyperliquid trading account, ready to use as the quote asset on USDH-denominated markets.
HyperEVM (Chain ID 999) is the EVM-compatible smart contract layer. It's where the broader Hyperliquid DeFi stack lives: lending, yield, ecosystem apps. USDH on HyperEVM works like a standard ERC-20, composable with smart contracts and usable across DeFi protocols wherever HyperEVM apps support it.
For most traders, the destination is HyperCore. For builders and DeFi users routing into HyperEVM lending or yield strategies, the destination is HyperEVM. The choice is explicit when you bridge.
How to Get USDH on Hyperliquid
There are three primary paths.
Bridge USDC to USDH for free with Across
The fastest path for crypto-native users is bridging USDC into USDH through Across, at a 1:1 rate, with zero bridge fees on transfers up to $1 million per transaction (source).
This is unusual. Most bridging into a destination stablecoin involves two steps: bridge USDC, then swap into the local asset. Each step costs basis points. Across collapses both into a single transaction with no slippage. Send $100,000 in USDC from any of 22+ supported chains, receive $100,000 in USDH on HyperCore. The only thing you pay is origin chain gas, typically a few cents.
The mechanics depend on size. Smaller transfers settle near-instantly through Across's intent-based architecture, with relayers fronting capital on the destination side. Larger transfers route through CCTP mint-and-burn for native USDC, which lets the route scale up to $1M per transfer without compromising execution quality.
The five-step flow:
Open across.to
Pick your origin chain and select USDC as the origin token
Pick HyperCore as the destination, USDH as the destination token
Enter the amount
Confirm
Fills land in roughly 2 seconds (source). 1 USDC in, 1 USDH out, ready to trade.
Onramp directly from a bank account
Onboarded users can mint USDH 1:1 from fiat through the Native Markets dashboard, with redemption back to USD on the same rails (source). That route bypasses crypto rails entirely and goes straight from a US bank account into HyperCore, which is the cleanest path for institutional and high-net-worth flows.
Earn yield on USDH
USDH isn't just a settlement currency. Through Native Markets' earn product, holders can deposit USDH into lending protocols and earn yield without leaving the app. For traders parking capital between trades or yield-seekers who want a productive stablecoin, that's a layer on top of the trading benefits.
USDH for Builders
USDH is permissionless on HyperEVM, which means builders can integrate it the same way they'd integrate any ERC-20 (source). The combination of AQA fee benefits on the trading side and ecosystem yield distribution on the reserve side gives apps a stablecoin that aligns with Hyperliquid's incentives by design.
Across's SDK supports USDH as a destination token from any of 22+ supported chains, so apps that want to onboard users into USDH from elsewhere can do it in a single integration. Native Markets' documentation covers minting, redemption, and reserve attestation flows for institutional integrators.
What USDH Means for the Stablecoin Market
The USDH bid process did something most DeFi governance hasn't managed: it forced the major stablecoin issuers to compete for an ecosystem on terms set by that ecosystem.
Paxos offered 95% revenue share. Ethena offered 95% plus eight figures in incentives. Frax offered 100%. The fact that Hyperliquid's validators chose Native Markets anyway, and that Native Markets' 100%-to-ecosystem framing is now the floor, has reframed the playing field. Stablecoin issuance went from a product the issuer offered to a service the chain accepted. Future protocol-native stablecoins will start their bid processes against this benchmark.
For Circle, the implications are concrete. Roughly $5.5 billion in USDC sat on Hyperliquid before USDH launched, around 7.5% of total USDC supply (source). Circle's response was to accelerate native USDC and CCTP deployment on Hyperliquid to defend share. The migration won't be forced; it'll be earned, by whichever asset offers traders better economics.
Right now, the better economics are USDH's.
