I’m building a mobile wallet that runs smoothly on both Android and iOS. The scope is intentionally focused: the user must be able to create or import a wallet, send and receive cryptocurrency, and review every past transfer in a clear, paginated transaction history. I care about a clean, modern interface and rock-solid key storage, but beyond that I’m flexible on the tech stack—React Native, Flutter, native Kotlin/Swift, or any other approach that you can defend from a security and performance standpoint all work for me. I have not locked in the specific chains yet, so the code should be architected in a way that lets me plug in Bitcoin, Ethereum, Ripple, or additional networks later without rewriting the whole stack. Suggested SDKs, APIs, or node services are welcome in your proposal. Deliverables • Full source code with clear build instructions • Test builds via TestFlight and Google Play’s internal track • Basic onboarding guide (create/import wallet, backup phrase) • Send/receive flow with QR scanning and copy-able addresses • Real-time transaction list pulled directly from the blockchain or a reliable indexer • Final documentation covering environment setup, dependencies, and how to swap or add chains Acceptance criteria: A fresh user can install the app, generate a wallet, back up their seed phrase, send a test transaction, and see that transaction appear in the history on both platforms without manual refresh. I’m ready to start as soon as I find someone who can meet these requirements and communicate progress clearly.
