# Hyperliquid

Hyperliquid is the exchange that LandingNet currently supports. It is a decentralized perpetuals exchange running on a L1 blockchain.

## Why Hyperliquid?

* **Non-custodial** -- You retain full control of your funds
* **High performance** -- Low latency order execution
* **Agent mechanism** -- `ApproveAgent` lets LandingNet trade on your behalf without accessing your keys
* **Deep liquidity** -- Sufficient market depth for copy trading strategies

## Supported Markets

* **Perpetuals** -- Perpetual futures contracts (primary)
* **Spot** -- Spot trading (limited support)

## How LandingNet Connects

Two EIP-712 signatures are required during [Account Setup](/doc/documentation/getting-started/account-setup.md#step-2-approve-builder-fees):

1. **Builder Fee Approval** -- Authorizes Hyperliquid to route builder fees to LandingNet on each trade
2. **Agent Approval** -- Grants LandingNet's agent trade-only permissions on a specific subaccount

| The agent can                              | The agent cannot                |
| ------------------------------------------ | ------------------------------- |
| Execute trades on your approved subaccount | Withdraw any funds              |
| Place market and limit orders              | Access your private keys        |
| Collect builder fees (capped)              | Trade on your master account    |
|                                            | Trade on unapproved subaccounts |

## Fees

Your total cost per trade: **Hyperliquid fee + LandingNet builder fee**. For LandingNet's fees, see [Fees & Limits](/doc/documentation/fees-and-limits.md). For Hyperliquid's base fees, refer to their [official documentation](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/fees).

## Subaccounts

Hyperliquid supports a master account and multiple named subaccounts. Each subaccount has its own balance, positions, and leverage settings -- isolated from each other and from the master account.

LandingNet trades on a dedicated subaccount (default name: **"Landingnet"**) to keep bot activity separate from your manual trading.

### Funding

After creating your subaccount during [Account Setup](/doc/documentation/getting-started/account-setup.md), transfer USDC to it from your master account on the [Hyperliquid app](https://app.hyperliquid.xyz/).

{% hint style="warning" %}
Your bots cannot trade if the subaccount has no funds. Make sure to transfer enough USDC to cover your intended trading activity.
{% endhint %}

### Restrictions

* You can only reuse an existing subaccount if it is named "Landingnet" (case-insensitive)
* To use a custom name, it must be a new subaccount
* Leverage settings are managed per-asset directly on Hyperliquid (used when leverage mode is "Native")
