Getting started

Integrating the widget

In your document, link and embed main-v1.js.

<script src="https://marinade-widget-delta.vercel.app/main-v1.js" data-preload />

Preloading Terminal

Assign the attribute data-preload to the script tag, the full application will be preloaded on your browser's (document.readyState === "complete") event.

<script src="https://marinade-widget-delta.vercel.app/main-v1.js" data-preload />

Then,

document.addEventListener('readystatechange', (e) => {
  if (document.readyState === 'complete') {
    window.Marinade.init({ endpoint: 'https://api.mainnet-beta.solana.com' });
  }
});

Built-in wallets, or passthrough wallets from your dApp

Mode 1: Wallet passthrough

If your user have connected their wallet via your dApp, you may passthrough the wallet instance via the init({ passThroughWallet: wallet }).

const App = () => {
  const { wallet } = useWallet();

  const initMarinade = () => {
    if (wallet) {
      window.Marinade.init({
        endpoint,
        passThroughWallet: wallet,
      });
    }
  };
};

Mode 2: Built-in wallet

If your user is not connected, Marinade Terminal have several built-in wallets that user can connect and perform swap directly.

---

Modal, Integrated, or Widget mode.

Modal

By default, Marinade renders as a modal and take up the whole screen.

window.Marinade.init({ displayMode: 'modal' });

Integrated

Integrated mode renders Marinade Terminal as a part of your dApp.

window.Marinade.init({ displayMode: 'integrated' });

Widget

Widget mode renders Marinade Terminal as a widget that can be placed at different position.

```tsx
window.Marinade.init({
  displayMode: 'widget',
  widgetStyle: {
        position: 'bottom-right', // 'bottom-left', 'top-left', 'top-right'
        size: 'default', // 'sm'
      },
});

---

Mode (Deprecated in v1)

Integrators on mode props needs to migrate to formProps, which offers more flexibility in customising interactions, and more capabilities.

Example on how to migrate from mode to formProps:

• default: Default mode, user can swap between any token pair. No action required.

• outputOnly: Output only mode, user can only swap to destination pair.

  // Can be mapped to:
  window.Marinade.init({
    endpoint: 'https://api.mainnet-beta.solana.com',
    formProps: {
      fixedInputMint: undefined,
      swapModeExactOut: undefined,
      fixedAmount: undefined,
      initialOutputMint: 'So11111111111111111111111111111111111111112',
      fixedOutputMint: true,
    },
  });

---

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.Marinade._instance) {
  window.Marinade.resume();
}

window.Marinade.close();

---

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.

---

onSuccess/onStakeError callback

onSuccess() reference can be provided, and will be called when swap is successful.

While onStakeError() will be called when an error has occurred.

window.Marinade.init({
  onSuccess: ({ txid }) => {
    console.log({ txid });
  },
  onStakeError: ({ error }) => {
    console.log('onStakeError', error);
  },
});

Customising styles: CSSProperties

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

Examples:

• Custom zIndex

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

• Custom height

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

Typescript Support

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

declare global {
  interface Window {
    Marinade: MarinadeTerminal;
  }
}
// ...
// ...
// ...
