Jupiter Terminal

Jupiter Terminal is an open-sourced, lite version of Jupiter that provides end-to-end swap flow by linking it in your HTML.

Visit our Demo / Playground over at https://terminal.jup.ag

With several templates to get you started, and auto generated code snippets.

Breaking change v1 to v2

Fee token account updated to use Jupiter referral token account. Check out Fee supports section

main-v3.js bundle (~70Kb gzipped)
- app bundle (~1.1Mb gzipped) are loaded on-demand when init() is called
- alternatively, preload app bundle with data-preload attributes
Agnostic
- Work with any dApp, Integrated or as a standalone Widget, or Modal
- Any framework, React, Plain HTML, and other frameworks.
- Responsive on any screen size
Form customisation

Built-in Wallets

- Passthrough Wallet from your dApp
- Powered by Unified Wallet Kit
Lite, but powerful
- Jupiter v6 API with Metis (New✨)
- State sharing with syncProps() (New✨)

Getting started

1. Setup HTML

Terminal is designed to work anywhere the web runs, including React, Plain HTML/JS, and many other frameworks.

<!-- Attach the loading script in your <head /> -->
<script src="https://terminal.jup.ag/main-v3.js" />

<!-- Optionally, preload for better experience, or integrated mode -->
<script src="https://terminal.jup.ag/main-v3.js" data-preload />

2. Initialize Jupiter Terminal

Scenario 1: Terminal as part of your dApp (Passthrough Wallet)

Your dApp already has a <WalletProvider />.

window.Jupiter.init({ enableWalletPassthrough: true });

Then, syncronise wallet state between your dApp and Jupiter Terminal with syncProps()

import { useWallet } from '@solana/wallet-adapter-react'; // Or @jup-ag/wallet-adapter;

const passthroughWalletContextState = useWallet();
useEffect(() => {
  if (!window.Jupiter.syncProps) return;
  window.Jupiter.syncProps({ passthroughWalletContextState });
}, [passthroughWalletContextState.connected, props]);

Scenario 2: Standalone Terminal

Your dApp does not have a <WalletProvider />, or is a plain HTML/JS website.

window.Jupiter.init({});

3. Setup other props

window.Jupiter.init({
  /** Required
   * Solana RPC endpoint
   * We do not recommend using the public RPC endpoint for production dApp, you will get severely rate-limited
   */
  endpoint: 'https://api.mainnet-beta.solana.com',
  // ...other props
});

4. Finishing touches

Terminal are light, but full of features, such as customising form behaviour, fees, styling and much more.

Go to our Demo to explore all these features, with automagically generated integration code.

Or, check out our fully typed API reference for more details.

Additional API Reference

Typescript Support

Since Jupiter Terminal is not published on npm, and are only importable via CDN, to get proper typing, you can create a typing decalarion jupiter-terminal.d.ts file in your project, and copy the contents in src/types/index.d.ts

declare global {
  interface Window {
    Jupiter: JupiterTerminal;
  }
}
// ...
// ...
// ...

Fee supports

Similar to Jupiter, Jupiter Terminal supports fee for integrators.

There are no protocol fees on Jupiter, but integrators can introduce a platform fee on swaps. The platform fee is provided in basis points, e.g. 20 bps for 0.2% of the token output.

Refer to Adding your own fees docs for more details.

Note: You will need to create the Token fee accounts to collect the platform fee.

By referral key `referralAccount` (easiest)

const TEST_PLATFORM_FEE_AND_ACCOUNTS = {
  referralAccount: '2XEYFwLBkLUxkQx5ZpFAAMzWhQxS4A9QzjhcPhUwhfwy',
  feeBps: 100,
};

window.Jupiter.init({
  // ...
  platformFeeAndAccounts: TEST_PLATFORM_FEE_AND_ACCOUNTS,
});

By defined fee accounts

Alternatively, you can derive yourself the fee accounts via Set your fee token account and declare them like so:

const TEST_PLATFORM_FEE_AND_ACCOUNTS = {
  feeBps: 100,
  feeAccounts,
};

window.Jupiter.init({
  // ...
  platformFeeAndAccounts: TEST_PLATFORM_FEE_AND_ACCOUNTS,
});

Resuming / Closing activity

Everytime init() is called, it will create a new activity.
If you want to resume the previous activity, you can use resume().
close() function only hide the widget.

if (window.Jupiter._instance) {
  window.Jupiter.resume();
}

window.Jupiter.close();

Strict Token List

strictTokenList?: boolean;
Default: true

The Jupiter Token List API is an open, collaborative, and dynamic token list to make trading on Solana more transparent and safer for users and developers. It is true by default to ensure that only validated tokens are shown.

Learn more at: https://station.jup.ag/docs/token-list/token-list-api

Default Explorer

defaultExplorer?: 'Solana Explorer' | 'Solscan' | 'Solana Beach' | 'SolanaFM';
Default: Solana Explorer

The default explorer is set to Solana Explorer;

You can change the default explorer by passing in the explorer name to the defaultExplorer prop.

Terminal callbacks

Callbacks that may be useful for your dApp, from form updates, to swap success/error.

window.Jupiter.init({
  /** Callbacks */
  /** When an error has occured during swap */
  onSwapError ({ error, quoteResponseMeta }: { error TransactionError; quoteResponseMeta: QuoteResponseMeta | null }) {}
  /** When a swap has been successful */
  onSuccess ({ txid, swapResult, quoteResponseMeta }: { txid: string; swapResult: SwapResult; quoteResponseMeta: QuoteResponseMeta | null }) {}
  /** Callback when there's changes to the form */
  onFormUpdate (form: IForm) {}
  /** Callback when there's changes to the screen */
  onScreenUpdate (screen: IScreen) {}

  /** Advanced usage */
  /** onRequestIxCallback(), refer to dedicated section below */
});

Customising styles: CSSProperties

Any CSS-in-JS can be injected to the outer-most container via containerStyles api.

Examples:

Custom zIndex

window.Jupiter.init({
  // ...
  containerStyles: { zIndex: 100 },
});

Custom height

window.Jupiter.init({
  // ...
  containerStyles: { maxHeight: '90vh' },
});

Customising className: Tailwind className

Tailwind classes can be injected to the outer-most container via containerClassName api.

Example:

Custom breakpoints

window.Jupiter.init({
  // ...
  containerClassName: 'max-h-[90vh] lg:max-h-[600px]',
});

onRequestIxCallback

Request Terminal to return instructions instead of transaction, so you can compose using the instructions returned.

Be sure to return SwapResult back to Terminal, so Terminal can handle screen/state transitioning.

const onRequestIxCallback: IInit['onRequestIxCallback'] = async (ixAndCb) => {};

maxAccounts

Limit the number of accounts to be used by the Swap Instructions.

NPM support

"@solana/spl-token": "^0.1.8",
"@solana/web3.js": "^1.87.6",

As of [email protected], Terminal is now available as an NPM package, however, some peer dependencies are required to be installed.

import { init, syncProps } from '@jup-ag/terminal';
import '@jup-ag/terminal/css';

import { useWallet } from '@solana/wallet-adapter-react'; // Or @jup-ag/wallet-adapter;
const walletContextState = useWallet();
useEffect(() => {
  init({
    displayMode: 'integrated',
    integratedTargetId: 'integrated-terminal',
    endpoint: 'https://api.mainnet-beta.solana.com',
  });
}, []);

// Optional: To make sure passthrough wallet are synced
useEffect(() => {
  syncProps({ passthroughWalletContextState: walletContextState });
}, [walletContextState]);
