</script>

React Native

Quick Start

Info endpoint

import * as hl from "@nktkas/hyperliquid";

const transport = new hl.HttpTransport();
const infoClient = new hl.InfoClient({ transport });

const openOrders = await infoClient.openOrders({ user: "0x..." });

Exchange endpoint

import * as hl from "@nktkas/hyperliquid";

const privateKey = "0x..."; // or `viem`, `ethers`

const transport = new hl.HttpTransport();
const exchClient = new hl.ExchangeClient({ wallet: privateKey, transport });

const result = await exchClient.order({
    orders: [{
        a: 0,
        b: true,
        p: "30000",
        s: "0.1",
        r: false,
        t: {
            limit: {
                tif: "Gtc",
            },
        },
    }],
    grouping: "na",
});

Subscription

import * as hl from "@nktkas/hyperliquid";

const transport = new hl.WebSocketTransport();
const subsClient = new hl.SubscriptionClient({ transport });

const sub = await subsClient.allMids((event) => {
    console.log(event);
});

await sub.unsubscribe(); // unsubscribe from the event

Multi-Sign

import * as hl from "@nktkas/hyperliquid";

const multiSignAddress = "0x...";
const signers = [
    "0x...", // Private key; or any other wallet libraries
] as const;

const transport = new hl.HttpTransport();
const multiSignClient = new hl.MultiSignClient({ transport, multiSignAddress, signers }); // extends `ExchangeClient`

const data = await multiSignClient.approveAgent({ // same API as `ExchangeClient`
    agentAddress: "0x...",
    agentName: "agentName",
});

Usage

1) Initialize Transport

First, choose and configure your transport layer (more details in the API Reference):

import * as hl from "@nktkas/hyperliquid";

// 1. HTTP Transport: suitable for one-time requests or serverless environments
const httpTransport = new hl.HttpTransport(); // Accepts optional parameters (e.g. isTestnet, timeout, etc.)

// 2. WebSocket Transport: has better network latency than HTTP transport
const wsTransport = new hl.WebSocketTransport(); // Accepts optional parameters (e.g. url, timeout, reconnect, etc.)

2) Initialize Client

Next, initialize a client with the transport layer (more details in the API Reference):

Create InfoClient

import * as hl from "@nktkas/hyperliquid";

const transport = new hl.HttpTransport(); // or `WebSocketTransport`
const infoClient = new hl.InfoClient({ transport });

Create ExchangeClient

import * as hl from "@nktkas/hyperliquid";
import { createWalletClient, custom } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { ethers } from "ethers";

const transport = new hl.HttpTransport(); // or `WebSocketTransport`

// 1. Using private key directly
const privateKey = "0x...";
const exchClient_privateKey = new hl.ExchangeClient({ wallet: privateKey, transport });

// 2. Using Viem
const viemAccount = privateKeyToAccount("0x...");
const exchClient_viem = new hl.ExchangeClient({ wallet: viemAccount, transport });

// 3. Using Ethers (or Ethers V5)
const ethersWallet = new ethers.Wallet("0x...");
const exchClient_ethers = new hl.ExchangeClient({ wallet: ethersWallet, transport });

// 4. Using external wallet (e.g. MetaMask) via Viem
const [account] = await window.ethereum.request({ method: "eth_requestAccounts" });
const externalWallet = createWalletClient({ account, transport: custom(window.ethereum) });
const exchClient_viemMetamask = new hl.ExchangeClient({ wallet: externalWallet, transport });

// 5. Using external wallet (e.g. MetaMask) via `window.ethereum`
const exchClient_windowMetamask = new hl.ExchangeClient({ wallet: window.ethereum, transport });

Create SubscriptionClient

import * as hl from "@nktkas/hyperliquid";

const transport = new hl.WebSocketTransport(); // only `WebSocketTransport`
const subsClient = new hl.SubscriptionClient({ transport });

Create MultiSignClient

import * as hl from "@nktkas/hyperliquid";
import { privateKeyToAccount } from "viem/accounts";
import { ethers } from "ethers";

const multiSignAddress = "0x...";
const signers = [
    privateKeyToAccount("0x..."), // first is leader for multi-sign transaction, must contain own address
    new ethers.Wallet("0x..."),
    { // can be a custom async wallet
        async signTypedData(params: {
            domain: {
                name: string;
                version: string;
                chainId: number;
                verifyingContract: Hex;
            };
            types: {
                [key: string]: {
                    name: string;
                    type: string;
                }[];
            };
            primaryType: string;
            message: Record<string, unknown>;
        }): Promise<Hex> {
            // Custom signer logic
            return "0x..."; // return hex signature
        },
    },
    "0x...", // private key directly
];

const transport = new hl.HttpTransport();
const multiSignClient = new hl.MultiSignClient({ transport, multiSignAddress, signers }); // extends `ExchangeClient`

3) Use Client

Finally, use client methods to interact with the Hyperliquid API (more details in the API Reference):

Example of using an InfoClient

import * as hl from "@nktkas/hyperliquid";

const transport = new hl.HttpTransport();
const infoClient = new hl.InfoClient({ transport });

// L2 Book
const l2Book = await infoClient.l2Book({ coin: "BTC" });

// Account clearinghouse state
const clearinghouseState = await infoClient.clearinghouseState({ user: "0x..." });

// Open orders
const openOrders = await infoClient.openOrders({ user: "0x..." });

Example of using an ExchangeClient

import * as hl from "@nktkas/hyperliquid";

const privateKey = "0x..."; // or `viem`, `ethers`

const transport = new hl.HttpTransport();
const exchClient = new hl.ExchangeClient({ wallet: privateKey, transport });

// Place an orders
const result = await exchClient.order({
    orders: [{
        a: 0,
        b: true,
        p: "30000",
        s: "0.1",
        r: false,
        t: {
            limit: {
                tif: "Gtc",
            },
        },
    }],
    grouping: "na",
});

// Approve an agent
const result = await exchClient.approveAgent({
    agentAddress: "0x...",
    agentName: "agentName",
});

// Withdraw funds
const result = await exchClient.withdraw3({
    destination: account.address,
    amount: "100",
});

Example of using a SubscriptionClient

import * as hl from "@nktkas/hyperliquid";

const transport = new hl.WebSocketTransport();
const subsClient = new hl.SubscriptionClient({ transport });

// L2 Book updates
await subsClient.l2Book({ coin: "BTC" }, (data) => {
    console.log(data);
});

// User fills
await subsClient.userFills({ user: "0x..." }, (data) => {
    console.log(data);
});

// Candle updates
const sub = await subsClient.candle({ coin: "BTC", interval: "1h" }, (data) => {
    console.log(data);
});

Example of using a MultiSignClient

import * as hl from "@nktkas/hyperliquid";

const multiSignAddress = "0x...";
const signers = [
    "0x...", // Private keys
] as const;

const transport = new hl.HttpTransport();
const multiSignClient = new hl.MultiSignClient({ transport, multiSignAddress, signers });

// Interaction is the same as with `ExchangeClient`

// Place an orders
const result = await multiSignClient.order({
    orders: [{
        a: 0,
        b: true,
        p: "30000",
        s: "0.1",
        r: false,
        t: {
            limit: {
                tif: "Gtc",
            },
        },
    }],
    grouping: "na",
});

// Approve an agent
const result = await multiSignClient.approveAgent({
    agentAddress: "0x...",
    agentName: "agentName",
});

// Withdraw funds
const result = await multiSignClient.withdraw3({
    destination: account.address,
    amount: "100",
});

                ];
            },
    );

    // Same methods as `ExchangeClient`
}

Transports

Transport acts as a layer between class requests and Hyperliquid servers.

HTTP Transport

HTTP transport is suitable for one-off requests or serverless environments.

class HttpTransport {
    constructor(options?: {
        isTestnet?: boolean; // Whether to use testnet url (default: false)
        timeout?: number; // Request timeout in ms (default: 10_000)
        server?: { // Custom server URLs
            mainnet?: { api?: string | URL; rpc?: string | URL };
            testnet?: { api?: string | URL; rpc?: string | URL };
        };
        fetchOptions?: RequestInit; // A custom fetch options
        onRequest?: (request: Request) => MaybePromise<Request | void | null | undefined>; // A callback before request is sent
        onResponse?: (response: Response) => MaybePromise<Response | void | null | undefined>; // A callback after response is received
    });
}

WebSocket Transport

WebSocket transport has better network latency than HTTP transport.

class WebSocketTransport {
    constructor(options?: {
        url?: string | URL; // WebSocket URL (default: "wss://api.hyperliquid.xyz/ws")
        timeout?: number; // Request timeout in ms (default: 10_000)
        keepAlive?: {
            interval?: number; // Ping interval in ms (default: 30_000)
            timeout?: number; // Pong timeout in ms (default: same as `timeout` for requests)
        };
        reconnect?: {
            maxRetries?: number; // Maximum number of reconnection attempts (default: 3)
            connectionTimeout?: number; // Connection timeout in ms (default: 10_000)
            connectionDelay?: number | ((attempt: number) => number | Promise<number>); // Delay between reconnection (default: Exponential backoff (max 10s))
            shouldReconnect?: (event: CloseEvent) => boolean | Promise<boolean>; // Custom reconnection logic (default: Always reconnect)
            messageBuffer?: MessageBufferStrategy; // Message buffering strategy between reconnection (default: FIFO buffer)
        };
        autoResubscribe?: boolean; // Whether to automatically resubscribe to events after reconnection (default: true)
    });
    ready(signal?: AbortSignal): Promise<void>;
    close(signal?: AbortSignal): Promise<void>;
}

Additional Import Points

/types

The import point gives access to all Hyperliquid-related types, including the base types on which class methods are based.

/signing

The import point gives access to functions that generate signatures for Hyperliquid transactions.

Examples

Cancel order yourself

import { actionSorter, signL1Action } from "@nktkas/hyperliquid/signing";

const privateKey = "0x..."; // or `viem`, `ethers`

const nonce = Date.now();
const action = {
    type: "cancel",
    cancels: [
        { a: 0, o: 12345 },
    ],
} as const;

const signature = await signL1Action({
    wallet: privateKey,
    action: actionSorter[action.type](action),
    nonce,
});

// Send the signed action to the Hyperliquid API
const response = await fetch("https://api.hyperliquid.xyz/exchange", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ action, signature, nonce }),
});
const body = await response.json();

Approve agent yourself

import { signUserSignedAction, userSignedActionEip712Types } from "@nktkas/hyperliquid/signing";

const privateKey = "0x..."; // or `viem`, `ethers`

const action = {
    type: "approveAgent",
    signatureChainId: "0x66eee",
    hyperliquidChain: "Mainnet",
    agentAddress: "0x...",
    agentName: "Agent",
    nonce: Date.now(),
} as const;

const signature = await signUserSignedAction({
    wallet: privateKey,
    action,
    types: userSignedActionEip712Types[action.type],
});

// Send the signed action to the Hyperliquid API
const response = await fetch("https://api.hyperliquid.xyz/exchange", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ action, signature, nonce: action.nonce }),
});
const body = await response.json();

FAQ

How to execute an L1 action via an external wallet (e.g. MetaMask)?

Hyperliquid requires chain 1337 for L1 actions (open order, change leverage, etc.). There are two ways to execute an L1 action through an external wallet:

• (recommended) Create an Agent Wallet and execute all L1 actions through it
• Change the user's chain to 1337, however, the user will sign unreadable data

How to create a market order?

Hyperliquid doesn't have traditional market orders, but you can achieve market-like execution by placing limit orders with tif: "Ioc" and prices that guarantee immediate execution:

• For buys: set limit price >= current best ask
• For sells: set limit price <= current best bid
