I’m building a lightweight cryptocurrency wallet and I want an experienced developer to take it from concept to a polished, secure release. The scope is intentionally lean—clean UI, fast load times, and zero-friction onboarding—but it still has to hit the core expectations users have of a modern wallet. At minimum, the wallet must let a user: • generate or import a seed phrase • send and receive payments • view real-time balances and transaction history Our initial target assets are Bitcoin and Ethereum, with the option to add Litecoin or other EVM-compatible tokens once the core is stable. I’m flexible on platform: if you specialize in native iOS (Swift), native Android (Kotlin), React Native, Flutter, or even a responsive web PWA, make your case and show past wallet work that proves you can ship safely audited code. Security is non-negotiable. You should understand key-management best practices, encrypted local storage, and how to integrate with hardware wallets or WalletConnect-style protocols. A quick audit report (your own checklist or a third-party reviewer) will be part of final acceptance. Deliverables I need from you: • Working wallet app that passes a basic smoke test on the agreed platform • Well-structured, documented source code in Git, plus CI/CD scripts for repeatable builds • Short read-me covering build steps, dependencies, and how to extend the asset list • A hand-off call or video walkthrough so my team can maintain the project confidently If you have shipped a wallet before, can explain your security approach in plain language, and have references or code samples to back it up, let’s talk timelines and milestones.
