Crossmint + Soroswap + Defindex Integration POC

A proof of concept demonstrating the integration of Soroswap and Defindex with Crossmint wallets on the Stellar network.

Overview

This POC showcases how to:

• Authenticate users using Crossmint's embedded wallet solution
• Swap tokens (XLM to USDC) via Soroswap's DEX on Stellar Testnet
• Deposit assets into Defindex vaults for DeFi strategies

Tech Stack

• React 19 + TypeScript + Vite
• Crossmint SDK - Wallet authentication and transaction signing
• Stellar SDK - Blockchain interactions
• CSS Modules - Scoped styling with glassmorphism UI

Prerequisites

• Node.js 18+
• pnpm (recommended) or npm
• A Crossmint API key (get one here)

Setup

1. Clone the repository

   git clone <repository-url>
   cd crossmint-front-poc

2. Install dependencies

   pnpm install
   # or
   npm install

3. Configure environment variables

   Copy the example environment file and add your Crossmint API key:

   cp .env.example .env

   Edit .env and set your API key:

   VITE_CROSSMINT_API_KEY=your_crossmint_api_key_here
   

4. Run the development server

   pnpm dev
   # or
   npm run dev

5. Open in browser

   Navigate to http://localhost:5173

Usage

1. Click "Connect Wallet" to authenticate via Crossmint
2. View your XLM and USDC balances on the dashboard
3. Use "Swap XLM to USDC" to exchange tokens via Soroswap
4. Use "Deposit to Defindex" to invest in DeFi strategies
