EUR → USDC Widget

A Scriptable widget for iOS that displays real-time EUR to USDC conversion rates across multiple blockchain networks.

Features

• Multi-chain support: Shows conversion rates for Mainnet, Gnosis, Polygon, Arbitrum, and Linea
• Real-time prices: Fetches current prices from Llama.fi API
• Chain icons: Displays blockchain icons with automatic fallback
• Customizable amount: Easily configure the EUR amount to convert (default: €100)
• Dark theme: Beautiful dark gradient background optimized for iOS widgets
• Update timestamp: Shows when the widget was last updated

Installation

1. Install Scriptable from the App Store
2. Open Scriptable and tap the + button to create a new script
3. Copy the contents of eur-usdc-widget.js into the script editor
4. Name your script (e.g., "EUR → USDC Widget")
5. Save the script

Adding to Home Screen

1. Long press on your home screen to enter edit mode
2. Tap the + button in the top-left corner
3. Search for "Scriptable" and select it
4. Choose a widget size (Small, Medium, or Large)
5. Tap "Add Widget"
6. Long press the widget and select "Edit Widget"
7. Choose your script from the list

Configuration

Edit the EUROS_TO_SHOW constant at the top of the script to change the EUR amount:

const EUROS_TO_SHOW = 100; // change if you like

Supported Chains

• Mainnet (Ethereum)
• Gnosis (xDai)
• Polygon
• Arbitrum
• Linea

Each chain displays how much USDC you would receive for the configured EUR amount based on current market prices.

How It Works

1. Fetches current prices for EURe and USDC tokens from Llama.fi API
2. Calculates the conversion rate: (EUR amount × EURe price) / USDC price
3. Displays the result for each supported blockchain network
4. Shows chain icons (cached locally for performance)
5. Displays update timestamp

Requirements

• iOS 14.0 or later
• Scriptable app installed
• Internet connection for price data
