Project description:
"I want to launch an iOS and Android application that revolves around one specific cryptocurrency. The build combines three core modules: a secure wallet for sending, receiving and storing the coin, a simple exchange screen so users can buy or sell that same coin against fiat or stable-pairs, and a portfolio tracker that shows real-time balance, price and performance history.

Security and trust sit at the centre of the project, so please integrate standard mobile-grade encryption for private keys, biometric login options and seamless QR code scanning. The app should connect directly to the coin’s mainnet or an official light-node API for on-chain transactions, then pull market data from a reliable price feed for the tracker and exchange section. I will supply the coin’s RPC details, branding assets and any required compliance text.

Deliverables
• Fully functional native iOS (Swift or SwiftUI) and Android (Kotlin) apps
• Clean, commented source code and build instructions
• End-to-end test build on TestFlight and Google Play internal track
• Basic admin endpoint or config file to adjust fees, spreads and API keys
• Post-launch bug-fix support window agreed in advance

Acceptance criteria: wallet create/import works flawlessly, transactions confirm on-chain, exchange orders execute at the quoted rate, and portfolio values update without noticeable lag.

If you have previous mobile crypto work, feel free to reference it when you respond so I can compare approaches and timelines." (client-provided description)
