Can You Add Hyperliquid to MetaMask?

Yes. HyperEVM is fully EVM-compatible, so MetaMask adds it as a standard custom network, no Snap or plug-in needed. Unlike a typical sidechain, it shares one chain and one HyperBFT consensus with HyperCore, Hyperliquid's native order book, letting EVM contracts read live order-book prices and positions directly.

ChainList adds it in a few clicks, while manual entry lets you pick the RPC endpoint. We use ChainList, then check each field against the official Hyperliquid docs before approving. A wrong Chain ID or a forum-copied RPC is the usual reason a setup fails or hits a malicious node.

MetaMask sometimes underestimates gas on HyperEVM, so transactions can fail until you raise the limit manually. Hyperliquid's support docs flag this and point users to Rabby, which has HyperEVM built in. Our best Hyperliquid wallets guide compares them.

How to Add HyperEVM to MetaMask

ChainList pulls verified parameters from a shared registry, not a random copy of the RPC:

1. Open ChainList: Go to the HyperEVM page and confirm the address bar reads chainlist.org before connecting MetaMask.
2. Check the details: Confirm the entry shows Chain ID 999 and HYPE as the currency. Searching "HyperEVM" also surfaces the testnet (Chain ID 998), so make sure you have mainnet.
3. Add to MetaMask: Click "Add to MetaMask," then compare the pop-up values against the official docs before approving.
4. Switch and fund: Select HyperEVM in the network menu, then fund a little HYPE for gas, covered below.

Once saved, dApps can prompt MetaMask to switch networks automatically. We read those prompts each time, since phishing sites can request lookalike networks with a swapped RPC. Approving one without checking is how people sign against a hostile node.

HyperEVM RPC and Chain ID

Without ChainList, open MetaMask's "Add a custom network" screen and enter the settings below. Confirm each value against the Hyperliquid developer docs, not third-party copies:

• Network Name: HyperEVM
• RPC URL: https://rpc.hyperliquid.xyz/evm
• Chain ID: 999
• Currency Symbol: HYPE
• Block Explorer URL: https://hyperevmscan.io

The public endpoint suits normal wallet use but is rate limited to 100 requests per minute per IP, so bots and indexers should use a dedicated provider like dRPC or 1RPC. HyperEVM runs the Cancun rule set with EIP-1559, and it burns both the base fee and the priority fee, removing HYPE from supply as activity rises.

HyperEVM Testnet RPC and Chain ID

For testing, add the HyperEVM testnet with the settings below, or connect it through ChainList:

• Network Name: HyperEVM Testnet
• RPC URL: https://rpc.hyperliquid-testnet.xyz/evm
• Chain ID: 998
• Currency Symbol: HYPE
• Block Explorer URL: https://testnet.purrsec.com

Testnet gas is paid in faucet HYPE, not real funds. Confirm the endpoint against the Hyperliquid docs before deploying.

How to Fund HYPE for Gas on HyperEVM

Adding the network gives you nothing to spend. Gas is paid in HYPE, so your EVM balance starts at zero, and most "stuck" setups trace back to this, not a bad RPC.

The cleanest method is an internal transfer. If you hold HYPE on Hyperliquid's spot balances, open the Portfolio page in the app and use the "EVM <-> Core Transfer" button to send some to the EVM side. Funds arrive in seconds and appear in MetaMask once the network is selected. From another chain, bridge to Hyperliquid first, then buy HYPE on the spot market and transfer it.

A manual address method also exists, with real risk. Sending HYPE to 0x2222222222222222222222222222222222222222 moves it from HyperCore to the EVM, but that address only accepts HYPE. Other assets each have their own transfer address, and tokens sent to the wrong one are lost. We default to the in-app transfer for that reason.

About HyperEVM: Architecture and Ecosystem

Hyperliquid began as an on-chain perpetuals exchange, and HyperEVM is the general-purpose layer it added in February 2025. Both share state, so an EVM contract can settle against the same liquidity that powers the exchange.

Its dual-block design splits traffic by size. Small blocks land roughly once a second with a 2 million gas limit for everyday transactions, while big blocks arrive about once a minute with a 30 million gas limit for contract deployment, so quick transfers never queue behind a heavy one. Developers opt into big blocks to ship larger contracts.

Composability with HyperCore is the standout. Read precompiles let EVM contracts pull oracle prices, positions, and balances from the order book with no external feed, while the CoreWriter contract (live since mid-2025) sends actions back. That two-way link lets a HyperEVM lending market liquidate straight against the native order book.

Total value locked has grown past two billion dollars, putting HyperEVM among the larger chains on DeFiLlama. Most of it sits in native protocols: HyperLend and Felix for lending and the feUSD stablecoin, Hypurr and Hyperbeat for vaults and yield, and Kinetiq for liquid-staked HYPE, with Tether's USDT0 as the main dollar stablecoin.

Final Thoughts

Adding HyperEVM to MetaMask takes a minute through ChainList or a manual RPC entry, but funding a little HYPE for gas is what gets you transacting.

Verify the details against Hyperliquid's docs, keep the official RPC unless you have reason to change it, and never approve a network prompt or share a seed phrase with a site you have not vetted.

If MetaMask keeps throwing gas errors, Rabby's built-in HyperEVM support is the cleaner path to the chain's lending, staking, and stablecoin apps.
