I need a seasoned mobile developer to deliver a production-ready iOS and Android app that runs on Binance Smart Chain. The core flow is simple: users sign up with multi-factor authentication, invite friends, and earn on-chain rewards in our own cryptocurrency token whenever their network engages with the app. Because every reward must settle transparently on BSC, the project requires both a well-structured smart contract and the mobile clients that interact with it. Referral codes have to be tamper-proof, balances must update in real time, and payouts must be visible on-chain so anyone can verify them through BscScan. On the mobile side I expect polished native performance—whether that’s achieved with Flutter, React Native, Kotlin/Swift, or true native code is up to you, as long as the final binaries pass App Store / Google Play review. Security is paramount: MFA at login, encrypted storage of any sensitive data, and clean separation between the wallet module and general profile data. Key deliverables • iOS app (App Store-ready IPA) • Android app (Google Play-ready AAB) • Binance Smart Chain smart contract for referral + reward logic • Backend or on-chain method that enforces MFA and handles user/transaction metadata • Brief but thorough technical documentation and hand-off support For acceptance I will run the following checks: the contract will be audited on testnet, both apps must compile from source, and end-to-end reward claims should settle in a single block without manual intervention. If your portfolio shows live apps that combine secure auth, blockchain interaction, and a referral engine, that’s exactly what I’m after—send me links and a concise outline of the stack you propose so we can lock the milestones and move quickly.

What stood out to me is that this isn’t a “crypto app with a wallet bolted on” — it’s a referral-driven on-chain rewards system where correctness, transparency, and app-store readiness all matter equally. That’s the right bar. I’d approach this as a chain-anchored system with mobile clients as first-class citizens, not wrappers. Proposed stack * Mobile: Flutter (single codebase, near-native performance, App Store / Play-ready) or native Swift + Kotlin if you prefer strict native * Blockchain: Binance Smart Chain (Solidity), purpose-built referral + reward contract * Backend: Minimal Node.js service for MFA, user metadata, and orchestration (no custody of funds) * Auth & security: MFA at login, device-bound sessions, encrypted local storage, strict wallet isolation On-chain design * Referral codes generated and validated deterministically (tamper-proof) * Smart contract enforces reward rules and emits events for every payout * Rewards settle automatically in a single transaction and are verifiable on BscScan * No off-chain balance manipulation — mobile apps read directly from chain + indexed events Timeline * MVP: ~8–10 weeks end-to-end I’ve delivered production systems combining secure auth, referral engines, and blockchain settlement where “almost correct” wasn’t acceptable. Happy to walk through the contract flow and mobile security model before locking milestones. Best regards, Jenifer

Hello, I will deliver a production-ready iOS and Android app on Binance Smart Chain with MFA, a referral engine, and transparent on-chain rewards in your token. My approach is to build a secure, modular stack where the wallet module is isolated from profile data, implement a tamper-resistant referral system, and deploy a BSC smart contract that handles referral logic and one-block payouts verifiable on BscScan. The mobile front end will aim for native-like performance using your chosen path (React Native, Flutter, or true native), verified for App Store and Google Play submission, with encrypted storage and strong MFA at login. The backend or on-chain method will manage user/transaction metadata and enforce MFA, ensuring real-time balance updates and auditable payouts. I’ll provide concise technical documentation and thorough hand-off support. Do you have the tokenomics defined and deployed on BSC, or should I design and deploy the token as part of this project? MFA methods: which authentication factors should be supported (TOTP, WebAuthn, biometric) and how will fallback be handled? Wallet integration: will the app include a self-contained wallet module or integrate with an external wallet; how will seed/key management be handled? Real-time updates: preferred mechanism for balance updates and on-chain payout finality (1 block) and how to reflect them in the UI? App store compliance: any policy constraints for crypto apps and any required security/compliance standards to

A SECURE, ON CHAIN REFERRAL APP THAT STORES TRUST ON BSC NOT PROMISES You’re building more than a mobile app you’re shipping a verifiable reward system where every referral and payout must hold up on-chain, pass audits, and survive app store scrutiny. That requires tight coordination between smart contracts, mobile clients, and backend logic. At Plan D Studios, we’ve spent 12+ years delivering production mobile apps, secure backend systems, and transaction heavy platforms fully in house, no outsourcing. How we’d approach this MVP: • Cross-platform mobile app (Flutter or native Swift/Kotlin) for App Store & Google Play compliance • Secure authentication flow with MFA and encrypted local storage • Clear separation between wallet logic and user profile data • Binance Smart Chain smart contract handling referral validation and reward distribution • Real time balance updates sourced directly from on chain data (BscScan verifiable) • Backend layer for MFA enforcement, metadata, and non custodial coordination You’ll receive store ready binaries, a tested BSC contract, and concise technical documentation for audit and handover. Would you prefer the reward logic to be fully on chain, or partially orchestrated with backend validation for flexibility? Let’s align and move fast. Regards, Haider

Hello There!!! ⚜⭐⭐⭐⭐⚜(( BSC Powered Mobile App with Secure Referrals and On Chain Rewards ))⚜⭐⭐⭐⭐⚜ What stands out here is your focus on verifiable on chain rewards paired with real mobile app quality. You are not just launching a token feature, you are building a production ready ecosystem that must pass store reviews and blockchain scrutiny at the same time. You are looking for a mobile and blockchain solution where iOS and Android apps interact cleanly with a Binance Smart Chain contract, handle secure sign up with multi factor authentication, and distribute referral rewards transparently in a single block. I have delivered mobile apps that integrate blockchain transactions, secure authentication flows, and real time balance updates, along with smart contracts designed for traceability and audit readiness. My approach would be to design the smart contract first around referral integrity and reward finality, then connect it to a secure mobile layer with clear separation between wallet logic and user data. Three most important features of this project: 1. Tamper proof referral and reward smart contract on Binance Smart Chain 2. iOS and Android apps with secure MFA and encrypted local storage 3. Real time on chain reward visibility with seamless BscScan verification If you would like, we can review your preferred stack and define clean milestones before moving forward.

Hello, I have reviewed the details of your project. i will deliver a cross platform mobile app using flutter with native performance for ios and android. user sign up will use email phone and multifactor verification handled by a secure backend service. sensitive data stays encrypted on device and wallet data stays isolated from profile data. onchain logic will live in a binance smart chain smart contract written in solidity that manages referral codes reward distribution and balances. referral links will hash into the contract so they cannot be altered. every reward claim will settle directly on bsc and remain visible through bscscan. the mobile app will connect to the contract through a web3 provider and update balances in realtime after each confirmed block. the backend will only manage auth metadata and invite tracking without touching funds. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you.
