HyperEVM: chain ID, RPC URLs and explorers

The HyperEVM chain ID is 999, according to Hyperliquid's own docs, and the official RPC at https://rpc.hyperliquid.xyz/evm returned 999 when we tested it today. HYPE, the gas coin, trades at $72.85 on CoinGecko at this check.

HyperEVM Chain ID Sources Disagree

HyperEVM chain ID sources disagree on 999. Hyperliquid's wallet guide says to add the network with chain ID 999, and the official RPC returns 0x3e7, which is 999. chainid.network, the registry built from the ethereum-lists project, lists 999 as Wanchain Testnet and has no HyperEVM mainnet entry.²

A third registry sides with Hyperliquid: Chainlist's page for chain 999 is titled HyperEVM, and Hyperliquid's docs link to it.³

For a wallet user this means one thing: type the values from Hyperliquid's docs by hand, or use Chainlist, and check that the network name and the HYPE symbol appear before you confirm. A wallet or tool that reads chainid.network may label 999 as Wanchain Testnet with WAN as the coin, and that label is wrong for HyperEVM.

HyperEVM RPC URL Tested Today

The HyperEVM RPC URL that Hyperliquid publishes is https://rpc.hyperliquid.xyz/evm, and it passed our eth_chainId test today, November 8, 2026. Hyperliquid's docs give these wallet values:¹

Network name: Hyperliquid
Chain ID: 999
RPC URL: https://rpc.hyperliquid.xyz/evm
Currency symbol: HYPE
Explorer: https://hyperevmscan.io or https://www.hyperscan.com

That endpoint has no websocket support and uses the same IP rate limits as Hyperliquid's API server, the developer docs say.⁴ Three community endpoints also returned 999 today, but Hyperliquid's docs do not list them, so they stay off this page. The testnet runs on chain ID 998 at https://rpc.hyperliquid-testnet.xyz/evm, and the Hyperliquid testnet faucet page covers test HYPE.

Hyperliquid Explorer Options for HyperEVM

The Hyperliquid explorer options for HyperEVM in Hyperliquid's docs are HyperEVMScan at hyperevmscan.io, built by Etherscan, and Hyperscan at hyperscan.com, built by Blockscout, with Owlscan listed among builder tools.⁵

These explorers show HyperEVM blocks, contracts and 0x addresses. Trades, orders and perp positions on HyperCore are a separate part of Hyperliquid, so a HyperEVM explorer is the wrong place to look for them.

HyperEVM vs HyperCore

HyperEVM and HyperCore are the two parts of the Hyperliquid blockchain, and Hyperliquid's docs say HyperEVM is not a separate chain. HyperCore holds the onchain perpetual futures and spot order books; HyperEVM runs Ethereum-style smart contracts. Both are secured by HyperBFT, a consensus algorithm inspired by HotStuff.⁶

Because they share one state, a HyperEVM contract can read HyperCore order book prices and send orders to them directly.⁷ Moving HYPE between the two works by sending it to 0x2222222222222222222222222222222222222222. Hyperliquid's docs warn that this address takes HYPE only: any other asset sent there is lost, since each spot asset has its own transfer address.

Blocks come in two sizes. Small blocks arrive every second with a 3M gas limit, and big blocks every minute with a 30M gas limit, both in one sequence of block numbers.⁸

USDC and USDT on HyperEVM

USDC on HyperEVM has an official contract, 0xb88339CB7199b77E23DB6E890353E22632Ba630f, on Circle's address list, and a symbol call over the official RPC returned USDC today. The USDC contract address page lists the other chains.

Tether does not list an official USDT contract on HyperEVM as of November 8, 2026.¹⁰ A token named USDT on HyperEVM is not one Tether lists itself. HyperEVM went live on mainnet on February 18, 2025, The Block reported, and block 1 of chain 999 carries that date. Hyperliquid's docs still call HyperEVM alpha. Other networks and their IDs are collected on the chains overview.

Questions People Ask About HyperEVM: chain ID, RPC URLs and explorers

These are the questions people ask next about HyperEVM: chain ID, RPC URLs and explorers.

What is the HyperEVM chain ID?

The HyperEVM chain ID is 999 on mainnet and 998 on testnet, according to Hyperliquid's docs, and the official RPC returns 999. chainid.network lists 999 as Wanchain Testnet instead, so a wallet that shows WAN for 999 is reading that registry.

What is the HyperEVM RPC URL?

The HyperEVM RPC URL is https://rpc.hyperliquid.xyz/evm, the endpoint Hyperliquid's docs publish for mainnet. It passed our test today. It has no websocket support, and its rate limits match Hyperliquid's API server, and Hyperliquid's builder tools page lists RPC providers for heavier use.

What is the Hyperliquid explorer for HyperEVM?

The Hyperliquid explorer for HyperEVM can be HyperEVMScan at hyperevmscan.io or Hyperscan at hyperscan.com, the two Hyperliquid's wallet guide names. They cover HyperEVM blocks and contracts. HyperCore trading activity sits in a different part of Hyperliquid.

Is HyperEVM a separate chain from Hyperliquid?

HyperEVM is not a separate chain from Hyperliquid, its docs say. It shares one state with HyperCore and the same HyperBFT consensus, which lets contracts reach HyperCore's order books directly. It has its own EVM chain ID, 999, for wallets.
