Dock Apps

Pre-built applications that extend Stratos Vault with DeFi, tokenization, and compliance capabilities.

Overview

Dock Apps run as iframes within the Stratos Vault interface, with full access to multi-chain transaction signing, Canton smart contract operations, and user authentication via the Stratos Wallet SDK.

All dock apps share a common architecture:

React 19 + TypeScript + Vite frontend
Cloudflare Pages deployment with serverless API functions
@stratos/wallet-sdk for wallet integration
Daml smart contracts for Canton-based business logic
/api/package endpoint for DAR distribution

Building Custom Dock Apps

All dock apps follow the same integration pattern. See the Developer Introduction for building your own.

Common Pattern

typescript

import { getSDK } from '@stratos/wallet-sdk';

const sdk = getSDK();
const { user } = await sdk.connect();

// Canton operations
const contracts = await sdk.cantonQuery({
  templateId: 'packageId#Module:Template',
});

await sdk.cantonExercise({
  contractId: '...',
  templateId: 'packageId#Module:Template',
  choice: 'MyChoice',
  argument: { /* ... */ },
});

DAR Package Distribution

Each dock app exposes /api/package for automatic Daml package installation:

json

{
  "name": "App Name",
  "packageId": "abc123...",
  "darUrl": "/api/package/download",
  "templates": ["Module:Template1", "Module:Template2"]
}
