What works where
The table shows the shape. The catalogue lists every operation and the networks it runs on, and it is generated from the running system, so it is the answer when the two disagree.
One account, four addresses that match
Your account has the same address on every network. You can send tokens to it on any of them. The agent holds one key and signs for all four networks. It can act only on a network the service has switched on, and a plan that names any other network is refused. See Your account and your keys.Ethereum
Gas costs more here than on the other networks, so a small trade costs more of its own size. Ethereum has the full set of swaps, lending, loops and liquidity positions, plus deposits to Lighter. It has no property or rent operations.Base
Base carries the whole product. It is the only network with property and rent operations and with tokenized stocks.Arbitrum
Arbitrum has the same swaps, lending, loops, liquidity positions and orders as Ethereum. It has no property, rent or stock operations, and no Lighter deposits.HyperEVM
HyperEVM is Hyperliquid’s own network. It is small on purpose: you move USDC in and out, and you trade on Hyperliquid from here.- It carries three assets: HYPE, WHYPE and USDC.
- It has no swaps, no lending and no liquidity positions. A step that asks for one is refused.
- USDC reaches it from Ethereum, Base or Arbitrum through a crossing. WETH cannot.
- Transactions on HyperEVM are not tested on a copy of the network before they are sent. See how transactions are sent.
Networks that are not available
A plan cannot use any network outside these four. The service refuses it at the check, so money cannot be sent to a network the service does not run on. MegaETH is not switched on for plans.Where to go next
Moving between networks
Routes, fees and how long a crossing takes.
How transactions are sent
The fee payer, the check before every send, and what protects a swap.
