# Supported networks & chains

Which chains and networks the Vault and the extension support, and what can be signed.

## Chains

One Vault account gives you an address on each of these:

| Chain              | Address looks like                    | Send                              | dApp signing                                                                 | Notes                                                              |

## Built-in EVM networks

Ethereum Mainnet · BNB Smart Chain · Arbitrum One · Optimism · Base · Polygon · Linea · Avalanche · HyperEVM · Robinhood Chain. Any other EVM network can be added by hand (**Networks → Add a network**) or on a site's request.

## Swap & bridge routes

| Chain   | Swap             | Bridge                                                               |
| ------- | ---------------- | -------------------------------------------------------------------- |
| EVM     | LI.FI aggregator | LI.FI (EVM ↔ EVM, and to Solana / Bitcoin / Tron where routes exist) |
| Solana  | Jupiter          | via LI.FI routes                                                     |
| Tron    | SunSwap          | dedicated route                                                      |
| Stellar | Path payments    | —                                                                    |

## Hyperliquid

|                                         | Where                    | Signed by                                                          |
| --------------------------------------- | ------------------------ | ------------------------------------------------------------------ |
| Perps deposits and withdrawals          | USDC on **Arbitrum**     | the Vault                                                          |
| Orders                                  | HyperCore                | the [agent key](/browser-extension/hyperliquid-perps/agent-key.md) |
| HYPE spot ↔ **HyperEVM** (chain id 999) | both sides, same address | the Vault                                                          |

**HyperEVM** is a normal EVM network in the roster: HYPE is its native coin, and seven of its tokens ship in the built-in list. See [HYPE between HyperCore and HyperEVM](/browser-extension/hyperliquid-perps/hype-and-hyperevm.md).

{% hint style="info" %}
A **private-key account** only covers the chain(s) its key was made for: a hex key gives Ethereum + Tron; Solana, Sui and Stellar share the ed25519 key type; Bitcoin WIF is Bitcoin only.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.lockerprotocol.com/reference/supported-networks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
