TL;DR: Hyperliquid is a perpetual futures DEX with an on-chain order book, zero gas fees, and sub-second settlement. It's built to feel like a centralized exchange while keeping your assets in your custody. Over $4T in cumulative perp volume processed, $1.7B chain TVL, and a native stablecoin (USDH) that gets you lower fees. You can bridge into it for free via Across.
Centralized exchanges were supposed to be temporary. A stopgap while DeFi figured out how to be fast enough. Then years went by and most onchain trading still felt like placing orders through a fax machine. Slow execution, expensive gas, AMM slippage that punished anyone trading with real size.
Hyperliquid is what happens when someone actually builds the thing DEX traders have been asking for.
Hyperliquid in 60 Seconds
Hyperliquid is a Layer 1 blockchain purpose-built for derivatives trading, running an on-chain order book with zero gas fees and sub-second settlement. It supports perpetual contracts on BTC, ETH, SOL, and other major assets with leverage up to 40x. Unlike AMM-based DEXs, Hyperliquid uses a central limit order book (CLOB) executed entirely on-chain, giving traders the interface and execution quality of a centralized exchange without handing over custody of their funds.
The chain has processed over $4 trillion in cumulative perp volume and holds $1.7B in TVL as of early 2026. Those aren't DeFi-graded-on-a-curve numbers. Those are numbers that make centralized exchanges pay attention.
How Hyperliquid Works
Hyperliquid runs its own L1 blockchain with a custom consensus mechanism called HyperBFT, purpose-built for the throughput and latency that trading demands. This isn’t an app bolted onto Ethereum or rolled up on someone else’s stack. It’s a chain designed from scratch around one question: what would a trading blockchain look like if you started from zero?
The answer involves a few unusual choices:
On-chain order book. Most DEXs use AMMs because building a performant order book on-chain was considered impractical. Hyperliquid did it anyway. Limit orders, market orders, stop losses. All matched on-chain. The experience is closer to Binance than Uniswap, except the matching engine lives on a blockchain and your funds stay in your wallet.
Zero gas fees for trading. Hyperliquid uses EIP-712 signatures for trade execution, which means you sign orders off-chain and the chain processes them without charging gas. You read that correctly. No gas per trade. The friction that makes onchain trading feel expensive compared to a CEX is just gone.
Sub-second settlement. HyperBFT consensus delivers finality fast enough that the trading experience feels real-time. Place an order, it fills, your position updates. No waiting for block confirmations while the market moves against you.
The Three Layers
Hyperliquid’s architecture splits into three layers: HyperEVM for general-purpose smart contracts, HyperCore for the trading engine, and the Hyperliquid DEX as the primary trading application.
HyperEVM (Chain ID 999) is an EVM-compatible L1. If you’ve deployed contracts on Ethereum, you can deploy on HyperEVM. This is where the broader Hyperliquid DeFi stack lives and grows. Standard Solidity tooling with standard wallet support.
HyperCore (Chain ID 1337) is the performance layer underneath. This is where the order book matching, margin calculations, and trade settlement happen. It’s optimized specifically for trading workloads, separate from the general-purpose EVM layer so that DeFi contract activity doesn’t compete with trade execution for throughput.
Hyperliquid DEX is the perpetual trading application built on top of both layers. BTC up to 40x leverage. ETH up to 25x. Altcoins at 5-20x depending on the asset. This is what most users interact with, and it's the product that's driven over $4 trillion in cumulative perp volume.
The layered design is the key architectural bet. By separating trading from general EVM computation, Hyperliquid can optimize each layer independently. The trading engine doesn’t slow down because someone deployed a yield farm on HyperEVM.
USDH: Hyperliquid’s Native Stablecoin
USDH is Hyperliquid’s native stablecoin, offering 20% lower taker fees and 50% higher maker rebates compared to USDC on the platform. It’s pegged 1:1 to the dollar and designed as the default settlement currency for Hyperliquid trading.
The fee incentive is the real story here. If you’re trading on Hyperliquid with any frequency, the difference between USDC and USDH fees compounds fast. 20% lower taker fees on every trade isn’t a rounding error. It’s the kind of edge that active traders will rearrange their entire workflow to capture.
Getting USDH is straightforward. You can bridge USDC to USDH at a 1:1 rate through Across, and the bridge fee is $0. Literally zero. You pay origin chain gas (somewhere between $0.01 and $0.50 depending on your source chain) and that’s it. The conversion and bridge are the same transaction.
How to Get Started
Bridge USDC into USDH on Hyperliquid through Across for $0 in bridge fees, with 1:1 conversion and fast fills in seconds.
Go to app.across.to
Connect your wallet
Select your source chain and USDC
Set Hyperliquid as your destination and USDH as the output token
Confirm the transaction
Bridge fees: $0. You pay only origin chain gas. Fills from L2s (Arbitrum, Base, Optimism) take about 2 seconds. From Ethereum L1, about 10 seconds. Transfers up to $1M per transaction are supported.
You can also bridge USDC, USDT0, and HYPE to HyperEVM if you want to interact with the broader Hyperliquid DeFi stack rather than the perp DEX directly.
Frequently Asked Questions
