UI Components
Dev Wallet ships Lit Web Components for wallet management UI. These work in any framework — React, Vue, vanilla JS, or anything that renders HTML.
Quick Start: mountDevWallet
The simplest way to add the wallet UI:
import { mountDevWallet } from '@mysten/dev-wallet/ui';
// Mount the floating panel (default: appends to document.body)
const unmount = mountDevWallet(wallet);
// Mount into a specific container
const unmount = mountDevWallet(wallet, {
container: document.getElementById('wallet-root'),
});
// Clean up
unmount();The Wallet Panel
The <dev-wallet-panel> element renders a floating action button (FAB) in the bottom-right corner.
Clicking it opens a slide-out sidebar with tabs:
- Assets — account balances for each coin type
- Objects — owned NFTs and objects
- Settings — network switching, wallet configuration
The panel also shows the signing modal when a request is pending.
Settings Tab
The Settings tab lets you manage networks and accounts:

Using Components Directly
All components accept a wallet property:
<dev-wallet-panel></dev-wallet-panel>
<script type="module">
import { DevWallet } from '@mysten/dev-wallet';
import '@mysten/dev-wallet/ui';
const panel = document.querySelector('dev-wallet-panel');
panel.wallet = wallet;
</script>Styling
Components use Shadow DOM and CSS custom properties prefixed with --dev-wallet-*. They render in a
self-contained dark theme that doesn't interfere with your app's styles.
