How to Connect HyperEVM to MetaMask (RPC & Chain ID)

How to Connect HyperEVM to MetaMask

The easiest way to connect HyperEVM is through ChainList, a verified directory of EVM networks that publishes the official RPC endpoints, chain IDs, and native currency settings. 

Using ChainList ensures you don’t have to copy network details from unverified sources, reducing the risk of mistakes or connecting to the wrong RPC.

1. Open ChainList.org and connect your MetaMask wallet.
2. Use the search bar to type HyperEVM.
3. Select HyperEVM from the results and click Add to MetaMask.
4. MetaMask will show the network details including the RPC URL, Chain ID, and symbol. Double-check these match the Hyperliquid documentation.
5. Approve the request and confirm the network switch in MetaMask.

💡 Important Note: Adding HyperEVM to MetaMask lets you use HyperEVM dApps that support wallets directly. Perp DEX trading and HLP vault actions still occur in the Hyperliquid app, and funding or approvals are handled there.

HyperEVM RPC Details (Mainnet)

To add HyperEVM manually in MetaMask, use the following network settings:

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

Alternative RPC endpoints you can use if the main one is unavailable:

• https://hyperliquid.drpc.org
• https://rpc.hyperlend.finance
• https://rpc.hypurrscan.io

These settings let MetaMask recognize HyperEVM so you can interact with dApps, explorers, and tools that run on Hyperliquid’s EVM layer.

HyperEVM RPC Details (Testnet)

Here are the verified details for connecting to HyperEVM Testnet:

• Network Name: Hyperliquid EVM Testnet
• RPC URL: https://api.hyperliquid-testnet.xyz/evm
• Chain ID: 998
• Currency Symbol: HYPE
• Block Explorer (Testnet): https://app.hyperliquid-testnet.xyz/explorer

You can also optionally use alternative RPC endpoints such as https://hyperliquid-testnet.drpc.org (via dRPC) to improve redundancy or performance. 

Alternative HyperEVM Wallets to MetaMask

Beyond MetaMask, HyperEVM is accessible through several wallets that either natively integrate or allow custom EVM setup, though support varies in depth.

• Rabby Wallet – Natively integrated with HyperEVM, showing balances and dApp positions. It even offers Hyperliquid perp trading inside the wallet. Caveat: some users report the default gas limit for HyperEVM transactions can be too low, causing failures unless manually adjusted.
• OKX Wallet – A multi-chain wallet with EVM compatibility. HyperEVM can be added via custom RPC, and OKX’s App Connect supports dApps across EVM chains. However, there is no official confirmation yet that HyperEVM is pre-configured, so manual setup may be required.
• Leap Wallet – A newer wallet with EVM support that lets users add custom networks through RPC details. There’s no public confirmation of native HyperEVM support, so it should be treated as a manual-setup option only.

These wallets give users flexibility: Rabby offers the smoothest HyperEVM experience today, while OKX and Leap remain viable through RPC configuration.

What is the HyperEVM?

The HyperEVM is Hyperliquid’s Ethereum-compatible smart contract layer that runs alongside its core perp DEX infrastructure.

Unlike a typical sidechain or rollup, it shares state directly with HyperCore, meaning contracts can read live trading data like positions, balances, and oracle prices, and can also write intents back into the order book engine. 

This design lets developers build dApps, vaults, and automated strategies that tap directly into Hyperliquid’s deep liquidity and high-performance execution environment, while still using familiar EVM tooling.

Bottom Line

Connecting HyperEVM to MetaMask is the simplest way to unlock Hyperliquid’s growing ecosystem beyond the perp DEX. 

By setting up the network through ChainList or manual RPC details, you ensure secure access to HyperEVM dApps and tools while keeping control in your own wallet. 

Taking this step now positions you to explore new strategies, vaults, and applications as the ecosystem expands.
