HyperEVM: Is Hyperliquid EVM-Compatible? Chain ID 999, RPC Setup, Bridging and the Full DeFi Ecosystem Map (2026)

HyperEVM is Hyperliquid's Ethereum-compatible smart-contract layer: chain ID 999, gas paid in HYPE, and the ability to read HyperCore's live order books, prices and positions directly from Solidity. It shares state and consensus with the HyperCore exchange engine, which is what makes it different from every other EVM chain. As of September 2026 it hosts a full DeFi stack, from lending (HyperLend, Felix) and liquid staking (Kinetiq) to DEXs (Kittenswap, Project X), bridges (Unit, LayerZero) and yield vaults (Hyperbeat, Vapor, Nest, Liminal).

Key takeaways

• Is Hyperliquid EVM? Yes. HyperEVM is a standard EVM environment on the same L1 as HyperCore, secured by the same HyperBFT validators.
• Hyperliquid RPC: https://rpc.hyperliquid.xyz/evm, chain ID 999, symbol HYPE; testnet chain ID 998.
• Dual-block architecture: fast small blocks (1 second, 2M gas) for normal transactions and slower large blocks (1 minute, 30M gas) for heavy deployments.
• Precompiles and CoreWriter let contracts read HyperCore state (prices, balances, positions) and send actions (orders, transfers) to the exchange.
• The Hyperliquid DeFi ecosystem is built around the exchange: lending against perp collateral, liquid-staked HYPE (kHYPE), stablecoins, native-asset bridging via Unit, and structured yield on HLP and HIP-3 markets.
• Risks: HyperEVM is newer than Ethereum, has less battle-tested tooling, and its apps are exposed to the exchange's own risks (validator set, bridge, market events).

What is HyperEVM, and is Hyperliquid EVM-compatible?

Hyperliquid launched in 2023 as a single-purpose chain: an order-book exchange for perps, with every order, cancel and liquidation processed by a custom state machine called HyperCore. That engine is fast precisely because it is not a general-purpose virtual machine. But a chain with no smart contracts cannot host lending, DEX aggregators, stablecoins or the thousand other things DeFi builders want to ship.

HyperEVM is the answer. It is an Ethereum Virtual Machine execution environment that runs on the same Hyperliquid L1, agreed on by the same HyperBFT validators, and (crucially) able to see HyperCore's state. It went live on mainnet in February 2025 and has matured through 2026 into a full ecosystem.

So when people ask "is hyperliquid evm?", the accurate answer is: Hyperliquid the chain is not only an EVM chain, but it includes a first-class EVM. You can deploy Solidity contracts with Hardhat or Foundry, connect MetaMask or Rabby, use ERC-20 tokens and ERC-721 NFTs, and interact with it exactly as you would with Arbitrum or Base. The difference is what those contracts can reach.

For the big-picture explanation of the chain and its exchange, start with what is Hyperliquid. This page focuses on the EVM side and the apps built on it.

How HyperEVM works: chain ID 999, dual blocks, HYPE gas

Chain ID and gas

HyperEVM's mainnet chain ID is 999 (testnet 998). Gas is paid in HYPE, the same token that secures the network through staking and pays trading-fee discounts. Gas fees are low, typically fractions of a cent for a transfer, and HYPE spent on gas is burned. Note the contrast with HyperCore: trading on the order book is gas-free, while EVM transactions cost a little HYPE.

Dual-block architecture

HyperEVM produces two interleaved kinds of blocks, which is unusual and worth understanding if you build or use apps here.

• Small blocks are produced roughly every second with a gas limit of around 2 million. They handle the everyday transactions: swaps, transfers, lending deposits.
• Large blocks are produced roughly every minute with a gas limit of around 30 million. They exist for heavy operations such as contract deployments or big batch transactions.

A transaction is routed to the large-block lane by a flag the sender sets. For users this means small transactions confirm in about a second, while a large contract deployment might wait up to a minute. For developers it means you cannot assume Ethereum-style uniform block sizes.

Precompiles: reading HyperCore from Solidity

This is the feature that makes HyperEVM an "exchange-first" EVM. A set of read precompiles at reserved addresses expose HyperCore state to contracts: oracle and mark prices for every perp, spot balances, perp positions, vault equity, staking delegations, L1 block numbers and more. A lending protocol can price collateral from the exchange's own oracle rather than from an external feed. A vault can check its own perp positions on-chain before deciding whether to rebalance.

CoreWriter: sending actions to the exchange

Reading is half the story. CoreWriter is the system contract that lets an EVM contract send actions to HyperCore: place or cancel orders, transfer between spot and perp balances, delegate stake to a validator, or move assets between the EVM and Core sides. It arrived in mid-2025 and turned HyperEVM from an observer of the exchange into a participant. Protocols such as Liminal (delta-neutral vaults) and various automated market-making strategies are built on it.

How to add Hyperliquid RPC to MetaMask (or Rabby)

Adding HyperEVM to a wallet takes a minute. Use these exact values, as of September 2026:

Steps in MetaMask: open Settings, choose Networks, click Add network, then Add a network manually, paste the values above and save. Rabby, Coinbase Wallet, OKX Wallet and Phantom (EVM mode) follow the same pattern. Many wallets also detect the network automatically when you connect to a HyperEVM app, or you can add it with one click from Chainlist.

The public RPC is rate-limited. If you run bots or indexers, use a dedicated provider: QuickNode, dRPC, Alchemy-style services and several Hyperliquid-native providers offer HyperEVM endpoints. Testnet uses https://rpc.hyperliquid-testnet.xyz/evm with chain ID 998; our testnet and faucet guide explains how to get test HYPE.

Bridging between HyperCore and HyperEVM

A single Hyperliquid address has two balances: a HyperCore balance (what you trade with in the Hyperliquid app DEX) and a HyperEVM balance (what MetaMask sees). Moving between them is a native operation, not a third-party bridge.

Core to EVM. In the app, go to your portfolio, choose the token (HYPE, USDC, or any HIP-1 token that has an EVM link) and select transfer to EVM. The tokens appear in your EVM wallet within seconds. Under the hood this is a transfer to a system address that HyperCore and HyperEVM both recognise.

EVM to Core. Send the token to the system bridge address from your EVM wallet, or use the transfer button in a HyperEVM app that supports it. Again, near-instant.

Getting assets onto Hyperliquid in the first place. USDC arrives via the native Arbitrum bridge into HyperCore. BTC, ETH and SOL arrive natively via Unit (HyperUnit) as spot assets. Assets from other chains can land directly on HyperEVM through LayerZero (which is why "hyperliquid zro" is a common search: LayerZero's ZRO token and OFT standard are the messaging layer many HyperEVM tokens use), deBridge, Across, Relay and Jumper. Full instructions are in the bridge, deposit and wallets guide.

Hyperliquid DeFi ecosystem map (September 2026)

The Hyperliquid ecosystem has grown quickly because every app can plug into an exchange that already has billions in volume and deep liquidity. The table groups the main HyperEVM and ecosystem projects by category. TVL figures change daily; check DefiLlama's Hyperliquid page for current numbers.

Lending: HyperLend, Felix and HypurrFi

HyperLend is the Aave-style money market that became the largest TVL protocol on HyperEVM. Its edge is exchange-aware collateral: it can price kHYPE and HYPE from HyperCore's oracle and support assets that only exist on Hyperliquid. Felix takes the Liquity approach: deposit HYPE or other collateral, mint feUSD, and it has expanded into "Felix Vanilla" markets for simple lending and a HIP-3 deployment. HypurrFi is the third money market and tends to list newer, longer-tail assets. If you hold HYPE long-term and want liquidity without selling, these are where you go; compare rates before borrowing and remember that liquidations on HyperEVM are as unforgiving as on the perp engine.

Liquid staking: Kinetiq

HYPE staking yields around 2–2.5% as of September 2026 with a 7-day unstaking period, which locks capital. Kinetiq solves this with kHYPE, a liquid staking token that accrues staking rewards and can be used as collateral on HyperLend, swapped on Kittenswap or deposited into vaults. It is the dominant liquid staking protocol; StakedHYPE (stHYPE) is a smaller alternative. Details in the Hyperliquid staking guide.

Stablecoins: USDH, feUSD, USDe

The "USDH" story is worth telling because it shows how governance works here. In 2025 the validators ran a competitive process for the right to issue Hyperliquid's native USD stablecoin under the USDH ticker; Native Markets won against bids from Paxos, Frax, Ethena and others. USDH launched and was used as a quote asset for some spot pairs. In 2026 the protocol moved toward an "aligned quote asset" framework (AQAv2) that allows multiple stablecoins to qualify as quote assets under common rules, and USDH was wound down in favour of that model. Ethena's USDe and Felix's feUSD are the other significant native stables; USDC remains the collateral for perps.

Native assets: Unit

Unit (HyperUnit) is the infrastructure that lets you deposit real BTC, ETH and SOL and trade them as spot assets on HyperCore, then move them to HyperEVM. It is a guardian-network bridge rather than a fully trustless one, which is a risk to understand, but it is what made Hyperliquid a credible spot venue for majors.

DEXs: Kittenswap, Ramses, Valantis, Project X

Spot swaps on HyperEVM are dominated by Kittenswap, a ve(3,3) DEX with KITTEN emissions directed by voters, and Ramses (branded Hyperswap on Hyperliquid), the Arbitrum-born concentrated-liquidity DEX. Valantis brings modular pool architecture aimed at LSTs and stable pairs. Project X combines a DEX with a Hyperliquid trading terminal and earns via builder codes on perp order flow. HyperCore's own spot order book is still where the most liquid HYPE/USDC trading happens, so for large swaps compare both venues.

Yield: Vapor, Nest, Liminal, Hyperbeat

These protocols package Hyperliquid-native yield. Hyperbeat runs vaults on HYPE, kHYPE and stables. Vapor builds automated strategies around the exchange. Nest brings real-world-asset yield (treasury-backed products) onto HyperEVM. Liminal runs delta-neutral vaults that hedge on HyperCore perps and HIP-3 markets via CoreWriter. All of them compete with the native HLP vault, which remains the simplest way to earn on the exchange itself.

Perp front-ends and NFTs

Based and Dreamcash are consumer front-ends that hide the wallet and gas complexity and route to HyperCore; they earn from builder codes, which we explain in trading bots and builder codes. The Hyperliquid NFT scene is small but real: Hypurr, the cat mascot collection tied to the airdrop cohort, remains the flagship, with a handful of EVM marketplaces supporting ERC-721 trading.

Tokens, listings and integrations people search for

A cluster of searches pairs "hyperliquid" with another project's name. Most are either ecosystem integrations or spot/perp listings. A quick guide:

• Ethena hyperliquid: USDe is live on HyperEVM and Ethena was a bidder in the USDH process; ENA also trades as a perp.
• LayerZero / ZRO hyperliquid: LayerZero is the main cross-chain messaging layer for HyperEVM tokens (OFT standard); ZRO itself trades as a perp on HyperCore.
• Plasma / XPL hyperliquid: XPL, the token of the stablecoin chain Plasma, listed as a Hyperliquid perp around its 2025 launch and was one of the most traded new listings of that period.
• Zora hyperliquid: ZORA trades as a perp; it is not a HyperEVM integration.
• 0G hyperliquid: the 0G AI-data token has a perp listing; searches spiked around its TGE.
• Monad, MegaETH, Fogo hyperliquid: competitor chains, discussed below, whose tokens also have perp or pre-launch markets on Hyperliquid.
• ZK hyperliquid: ZK-rollup tokens trade as perps; more interestingly, "zk" also shows up because Lighter, the main rival DEX, is a zk-verified order book. Hyperliquid itself does not use zk proofs; see Hyperliquid vs Lighter.

The pattern to remember: with more than 200 perp markets and a permissionless spot standard, almost any mid-cap token has a Hyperliquid market. That is different from being built on Hyperliquid, which is what the ecosystem table above covers. Our crypto perps market page lists the major listings.

HyperEVM vs Monad, MegaETH, Solana and Fogo

Because 2025–2026 saw several high-performance chains launch, it is fair to ask how HyperEVM stacks up.

The one-line difference: Monad, MegaETH and Solana are general-purpose chains that hope trading apps will come; Hyperliquid is a trading venue that added a general-purpose chain. HyperEVM's raw throughput is not its selling point. Its selling point is that a lending protocol, a vault or a stablecoin can be built directly against the deepest on-chain order book in crypto, using its prices and its positions as native state. Fogo is the closest philosophical cousin (exchange-first, low latency) but on the Solana VM rather than EVM. For a deeper comparison of Hyperliquid as an L1 against Ethereum and Solana, see Hyperliquid vs Ethereum and Solana.

Risks of using HyperEVM and Hyperliquid DeFi

A one-line risk note is not enough here, because DeFi on a young chain stacks several risk layers.

• Validator and chain risk. HyperEVM inherits HyperCore's security model: a relatively small HyperBFT validator set compared with Ethereum. A consensus failure or governance intervention (as in the March 2025 JELLY episode) affects both sides of the chain.
• Smart-contract risk. HyperLend, Felix, Kittenswap and the rest are audited but young. HyperEVM's precompiles and CoreWriter are novel surface area that Ethereum contracts never had to reason about.
• Bridge risk. Unit is guardian-based; LayerZero and deBridge have their own trust assumptions; the Arbitrum USDC bridge is a contract holding billions.
• Liquidity and oracle risk in apps. Lending against kHYPE or long-tail assets can cascade if HyperCore prices gap. A crash like October 10, 2025 propagates instantly into EVM liquidations.
• Regulatory risk. The app geo-blocks the US and there is no KYC; regulatory changes can affect front-ends and stablecoin issuers.

Read is Hyperliquid safe before committing significant capital, and treat any advertised yield as variable and unguaranteed.

Bottom line

HyperEVM makes Hyperliquid a full DeFi platform rather than just an exchange. It is a standard EVM (chain ID 999, RPC rpc.hyperliquid.xyz/evm, gas in HYPE) with one decisive addition: contracts can read and write the state of the HyperCore order-book engine. That has produced a fast-growing ecosystem, led by HyperLend, Felix, Kinetiq, Kittenswap, Unit and a wave of yield vaults, that competitors like Monad and MegaETH cannot replicate without first building an exchange. As of September 2026 the tooling is mature enough for everyday use, but the chain is young, so size your exposure to any single protocol accordingly.
