Svelte Sui Wallet Adapter

A Sui wallet adapter for SvelteKit and Svelte 5.

Zero setup: no Tailwind, no shadcn-svelte, no peer UI dependencies. Components ship with their own scoped styles and are themeable via CSS custom properties.

Getting started

pnpm install @builders-of-stuff/svelte-sui-wallet-adapter

Usage

<!-- +page.svelte -->
<script lang="ts">
  import {
    ConnectButton,
    walletAdapter
  } from '@builders-of-stuff/svelte-sui-wallet-adapter';
</script>

<ConnectButton {walletAdapter} />

Pre-configured adapters are exported for each network: walletAdapter (mainnet), testnetWalletAdapter, devnetWalletAdapter, and localnetWalletAdapter. Or create your own:

import { createWalletAdapter } from '@builders-of-stuff/svelte-sui-wallet-adapter';

const walletAdapter = createWalletAdapter({
  network: 'testnet' // 'mainnet' | 'testnet' | 'devnet' | 'localnet'
  // baseUrl: 'https://my-own-fullnode.example.com:443',
  // autoConnect: false,           // reconnect to the last wallet on load (default true)
  // storageKey: 'my-app:wallet',  // localStorage key for persistence
  // preferredWallets: ['Slush'],  // wallet names to order first in the modal
  // slushWallet: { name: 'My App' }, // register the Slush web wallet
  // enokiWallets: {               // register zkLogin social-login wallets
  //   apiKey: 'enoki_public_...',
  //   providers: { google: { clientId: '....apps.googleusercontent.com' } }
  // }
});

zkLogin (Enoki) wallets

Pass enokiWallets to register zkLogin social-login wallets ("Sign in with Google", Facebook, Twitch) backed by Enoki. They show up in the connect modal alongside extension wallets and support the same signing API. Requires an Enoki public API key and OAuth client IDs; available on mainnet, testnet, and devnet (not localnet).

Any zkLogin wallet that implements the wallet standard also works without configuration — the adapter picks up every registered Sui wallet automatically (the Slush web wallet, registered via slushWallet, uses zkLogin under the hood).

Helpers are re-exported for distinguishing zkLogin wallets in custom UI: isEnokiWallet, isGoogleWallet, isFacebookWallet, isTwitchWallet, getWalletMetadata, and getSession.

Reading state and signing

The adapter exposes reactive state (Svelte 5 runes) and actions:

<script lang="ts">
  import { Transaction } from '@mysten/sui/transactions';
  import {
    ConnectButton,
    walletAdapter
  } from '@builders-of-stuff/svelte-sui-wallet-adapter';

  $effect(() => {
    console.log(walletAdapter.currentAccount);
    console.log(walletAdapter.isConnected);
  });

  async function doSomething() {
    const tx = new Transaction();
    // ... build the transaction ...

    const result = await walletAdapter.signAndExecuteTransaction({
      transaction: tx
    });

    // result is a SuiClientTypes.TransactionResult tagged union:
    if (result.$kind === 'Transaction') {
      console.log('digest:', result.Transaction.digest);
    }

    // Need events/object types/balance changes? Wait for the transaction:
    const confirmed = await walletAdapter.waitForTransaction({
      digest: (result.Transaction ?? result.FailedTransaction).digest,
      include: { events: true, objectTypes: true, balanceChanges: true }
    });
  }

  async function query() {
    // walletAdapter.suiClient is a SuiGrpcClient from @mysten/sui/grpc
    const owned = await walletAdapter.suiClient.core.listOwnedObjects({
      owner: walletAdapter.currentAccount!.address,
      include: { json: true }
    });
  }
</script>

<ConnectButton {walletAdapter} />

Other actions: connectWallet, disconnectWallet, switchAccount, switchWallet, signTransaction, executeTransaction, signPersonalMessage.

GraphQL

The adapter's client is gRPC, but the library exports the public GraphQL endpoint URLs for use with SuiGraphQLClient:

import { SuiGraphQLClient } from '@mysten/sui/graphql';
import { getGraphqlUrl } from '@builders-of-stuff/svelte-sui-wallet-adapter';

const graphqlClient = new SuiGraphQLClient({
  url: getGraphqlUrl('testnet'),
  network: 'testnet'
});

Theming

Components use scoped styles with --sswa-* CSS custom property hooks and follow the OS color scheme automatically (via light-dark()). Override any token globally:

:root {
  --sswa-primary: #4da2ff;
  --sswa-primary-foreground: #ffffff;
  --sswa-background: #ffffff;
  --sswa-foreground: #18181b;
  --sswa-secondary: #f4f4f5;
  --sswa-secondary-foreground: #18181b;
  --sswa-muted: #f4f4f5;
  --sswa-muted-foreground: #71717a;
  --sswa-border: #e4e4e7;
  --sswa-ring: #4da2ff;
  --sswa-radius: 0.75rem;
  --sswa-font-sans: inherit;
  --sswa-overlay: rgb(24 24 27 / 0.4);
}

To force a scheme instead of following the OS, set color-scheme: light (or dark) on an ancestor element.

Migrating from v2

v3 is a major overhaul:

• No more UI peer dependencies. Tailwind, shadcn-svelte, bits-ui, and svelte-radix are no longer required. Remove the styles.css import — the ./styles.css export is gone.
• gRPC client. walletAdapter.suiClient is now a SuiGrpcClient (@mysten/sui v2). JSON-RPC methods like getOwnedObjects and executeTransactionBlock are replaced by the core API (suiClient.core.listOwnedObjects, suiClient.core.executeTransaction, ...).
• createWalletAdapter options changed. rpcUrl → network (+ optional baseUrl). New: storage, storageKey, preferredWallets.
• Persistence + autoConnect. Connections persist to localStorage and autoConnect now defaults to true.
• Results changed. signAndExecuteTransaction/executeTransaction return a SuiClientTypes.TransactionResult tagged union (no more objectChanges/rawEffects).
• Removed. reportTransactionEffects (feature removed from the wallet standard; wallets that execute transactions handle effects reporting themselves), the deprecated sui:signMessage fallback in signPersonalMessage, and the internal setWalletRegistered/setWalletUnregistered/updateWalletAccounts actions.
• New. switchWallet, waitForTransaction, isReconnecting, "copy address" / "switch wallet" in the account dropdown, install links and connecting/error states in the connect modal.
• Node >= 22 is required (inherited from @mysten/sui v2).

Current known issues

• Components and adapters server-render safely, but wallet detection and connection are browser-only (the wallet standard lives in the browser)

Developing

Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:

npm run dev

Everything inside src/lib is part of the library, everything inside src/routes can be used as a showcase or preview app.
