How does Hyperliquid work?

Hyperliquid is really two things layered together: a purpose-built Layer 1 blockchain and, sitting on top of it, a flagship perpetual-futures and spot exchange. The key design decision is that the exchange runs on-chain but performs like a centralized exchange — a full order book with price-time priority matching, rather than the AMM/pool model most DeFi uses. Per DefiLlama, that perps market is currently doing about $4.1M in daily fees (~$3.3M of it the protocol's own revenue), which puts it among the most actively used derivatives protocols in crypto.

Here's how the pieces fit together:

The chain itself. Hyperliquid is its own Layer 1 (custom EVM, not Ethereum-based). It was built specifically so that every order, cancel, trade, and liquidation can be recorded transparently on-chain while still matching at high speed. The native asset is HYPE, and USDC is bridged in (native USDC is minted via CCTP, mostly from Arbitrum). The bridge currently holds around $6.4B in TVL per DefiLlama.

Order-book trading. On the perps and spot orderbooks, orders are matched in strict price-time priority — first-in-line at a given price gets filled first, exactly like a CEX. This gives you real order books, limit orders, and deep liquidity that AMM-style DEXs typically can't offer, but with the transparency and self-custody of on-chain infrastructure.

HLP — the liquidity vault. Hyperliquid doesn't rely on outside market makers in the usual way. Instead, a protocol-owned vault called the Hyperliquidity Provider (HLP) supplies liquidity using multiple market-making strategies, performs liquidations, earns yield on USDC, and collects a share of trading fees. It's community-owned. It currently holds about $185M in TVL per DefiLlama — that's what backs the deep, always-on books.

The broader ecosystem. Beyond perps and spot, Hyperliquid supports borrowing/lending, RWA projects, and EVM apps — so it's evolving into a general-purpose chain, not just an exchange. DefiLlama tracks several of these modules separately (spot orderbook ~$160M TVL, bridge ~$6.4B, HLP vault ~$185M, perps).

Trade-offs to be aware of:

• It's a centralized-style order book — great for liquidity and low slippage, but a different trust model than a peer-to-peer AMM. Validators secure the chain, and the exchange is custodial in the sense that you're trading against the protocol's books rather than a pool.
• Perp volume data isn't freely available from DefiLlama (requires their paid plan), so daily fees and revenue are the closest free proxy for how busy the platform is — and by that measure it's very active.

If you want, I can look up where to trade perps in general (and compare Hyperliquid against other perp DEXs by fee revenue), or pull the live price/trending context on HYPE itself.
