Overview
Seeker Eats is a mobile food delivery application that lets users order food and pay with USDC stablecoins on Solana. Built for the Solana Mobile ecosystem, it bridges the gap between crypto payments and real-world food delivery services.

The Problem
Spending crypto in the real world is still difficult. Most food delivery apps only accept traditional payment methods, forcing crypto users to off-ramp their assets before making everyday purchases.
Seeker Eats solves this by:
- Enabling direct USDC payments for food orders on Solana
- Settling merchants in USD through a crypto-to-fiat bridge
- Connecting to a global logistics network through DoorDash Drive
How It Works
Authentication
Users log in and get a wallet via Privy — no seed phrases to manage, still self-custodial.
Browse & Order
Users browse local restaurants, customize their orders, and checkout—all within a familiar mobile app experience.
Payments
Users pay with USDC on Solana. The app uses a crypto credit card integration (e.g., Kast) to pay merchants upfront in USD, so it works with existing restaurant systems without merchants touching crypto.
Logistics
Orders are fulfilled by the DoorDash Drive network, providing reliable delivery infrastructure and real-time tracking.
Communication
Twilio VoIP APIs facilitate communication between the platform and restaurants for order confirmation and status updates.
