Hi, Approach: I’ll build this using Flutter (iOS + Android) + Node.js backend + Firebase, ensuring a secure, real-time escrow system with smooth performance. I can develop a production-ready escrow app with a strong focus on secure payment flow, OTP verification, and reliable transaction handling. Core implementation: • OTP-based authentication (phone/email via Firebase) • Buyer → Paystack payment → status “Held” via secure webhooks • Seller delivery confirmation + buyer OTP verification • Automated fund release using Paystack transfer APIs • Dispute handling with admin override (hold/refund/release) Admin panel: • View all transactions • Pause, release, or refund funds • Monitor disputes and user activity I’ve worked on payment-driven systems and understand the importance of accuracy, trust, and fail-proof flows in escrow logic. We can communicate more on this matter. Kindly accept the offer so we can discuss further. Thank you Jennifer

Interesting project, I will build your escrow MVP — React Native app with Paystack checkout, fund-hold logic, OTP-verified release, and a web-based admin panel for dispute resolution and refunds. For the escrow core, I will implement a state machine tracking each transaction through defined stages — initiated, payment_held, delivered, confirmed, released, disputed. Every Paystack webhook updates the state atomically, so funds never release without a verified OTP confirmation. This prevents race conditions where a buyer and seller act simultaneously and keeps your audit trail clean for compliance. Questions: 1) For seller payouts, will you use Paystack Transfer or Paystack Split — do sellers already have Paystack subaccounts? Looking forward to potentially working together. Thanks, Kamran

Hi there, I have gone through your escrow workflow carefully, and I can build a secure mobile escrow system where payments are held via Paystack, verified through OTP, and released automatically after delivery confirmation, with full admin control for disputes and refunds. My approach will be to design a clean Flutter-based mobile app with a Node.js/Firebase backend, where Paystack webhooks handle payment states, and the escrow logic runs in an event-driven flow to ensure every transaction is tracked, secure, and consistent in real time. Then I will implement the core user flow — from transaction creation to payment hold, delivery confirmation, OTP verification, and final payout to the seller — along with push notifications and proper failure handling for edge cases. Once this is stable, I will build the admin panel to monitor all transactions, manage disputes, and allow manual intervention without breaking the escrow cycle. Thanks, Rahul A.

@corpmember29

Hello, I have reviewed your escrow MVP requirements and understand the complete workflow, including buyer-seller transactions, Paystack payment holding, OTP-based confirmation, and admin dispute handling. With 10+ years of experience in mobile and fintech application development, I have worked on similar secure payment flows and real-time systems. I propose using Flutter (or React Native) for cross-platform apps, Node.js backend with secure Paystack integration (webhooks, transfers), and Firebase for OTP, push notifications, and real-time updates. The admin panel will be web-based with full control over transactions, disputes, and refunds. Development will follow a structured agile approach: UI/UX → core escrow logic → payment integration → testing → deployment. Estimated timeline is 4–6 weeks for a production-ready MVP. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE. WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. I am available to start immediately and will ensure secure, scalable, and clean implementation aligned with your requirements. I eagerly await your positive response. Thanks.

As a skilled Full-stack Developer and Computer Scientist, I have a proven track record delivering fully scalable, robust, cross-platform mobile applications. Additionally, my expertise in using technologies such as React Native, Flutter and RESTful APIs makes me the ideal candidate for your project. In past engagements, I've successfully built native iOS and Android apps with similar functionalities to your Escrow MVP App for Buyers and Sellers. Apart from mobile development prowess, my proficiency in Firebase or similar tools ensures the implementation of real-time notifications and secure OTP dispatching - crucial aspects of this project. My experience integrating different payment gateways including Paystack prepares me well to deliver the kind of secure hooks you require for the secure transfer of funds between buyers and sellers. Moreover, your requirement for a user-friendly yet minimal UI falls within my realm of accomplishments as I prioritize user-experience when designing applications. I also understand that after deploying your app there might be a need for critical bug fixing hence I offer post-launch support during the first 30 days to ensure you have a smooth transition after project completion. Therefore, by choosing me you can expect an impeccable end-to-end digital solution implemented within your specified timeline. Let's work together to create an app that customers can trust and enjoy using!

Hi there, I have read your project requirement. You need a production-ready mobile escrow platform (iOS & Android) with OTP-based authentication, Paystack payment holding and release flow, real-time notifications, and an admin panel for dispute management and transaction control. We will build a secure cross-platform app (Flutter/React Native) with a robust backend (Node/Firebase) handling escrow logic, Paystack integration (webhooks, transfers, split payments), OTP verification, and real-time status updates. The system will include a clean, trust-focused UI, automated fund holding/release, dispute handling via admin panel, and complete deployment support (TestFlight + Play Store). Code will be modular, secure, and production-ready. Questions: ========= Do you want OTP via SMS provider (Twilio/Africa’s Talking) or Firebase Auth only? Should disputes include chat/evidence upload or simple admin resolution? Any regional compliance/KYC requirements for users and payouts? Do you have an existing Paystack business account configured for transfers? Best Regards, Srashtasoft Team

Your Paystack split-payment setup will fail under load if you're relying on synchronous transfer calls during the release flow. When 50 buyers confirm delivery simultaneously, those API requests will timeout and leave funds stuck in limbo. You need an asynchronous queue with retry logic and idempotency keys to guarantee every seller gets paid even if Paystack's API hiccups. Before I map out the architecture, I need clarity on two things. First - what's your dispute resolution SLA? If a buyer flags an issue, are you manually reviewing within 24 hours or do you need automated hold periods? Second - does Paystack's subaccount structure fit your business model, or are you planning to collect fees separately and batch-transfer to sellers? The answer changes how I design the webhook handlers. Here's the architectural approach: - REACT NATIVE + TYPESCRIPT: Build a component library with biometric auth fallback and offline transaction caching so users can review deals without network dependency. - PAYSTACK WEBHOOKS + REDIS QUEUE: Implement event-driven fund releases using Bull queues - if a webhook delivery fails, the system retries every 30 seconds for 72 hours before escalating to admin. - FIREBASE CLOUD MESSAGING + TWILIO: Dual-channel notifications (push + SMS) with delivery receipts stored in Firestore to prove compliance if disputes escalate legally. - OTP VALIDATION: Generate time-based codes with 5-minute expiry and rate-limit requests to 3 attempts per transaction to block brute-force attacks. - PHP ADMIN PANEL: Laravel backend with role-based access control, transaction logs exported to CSV for accounting, and one-click refund triggers that reverse Paystack charges within the 180-day window. I've built 3 fintech apps with Paystack integration, including a peer-to-peer lending platform that processed ₦40M in its first quarter without a single failed payout. The escrow logic you're describing has edge cases most developers miss - what happens if the buyer's OTP expires during confirmation? I'll architect fallback flows for every failure scenario. Let's schedule a 20-minute call to walk through the state machine and webhook security before I commit to a timeline. I don't start projects where the money flow isn't bulletproof.

@kareemmaize

Hi, The core of this project is not the mobile UI. It is the escrow state machine behind it. Success means every transaction moves cleanly from initiated to funded, held, delivered, confirmed, released, or disputed without ambiguity or duplicate money actions. The main failure point in escrow apps is weak handling around webhooks, OTP confirmation, and admin intervention. That is where duplicate releases, stuck funds, or invalid state transitions usually happen. I’d structure this around a backend-controlled transaction workflow with idempotent Paystack event handling, explicit status transitions, auditable admin actions, and a separate confirmation layer for buyer receipt before payout is triggered. The app should stay simple and trustworthy on the surface, while the backend enforces the real rules. I’d start by locking the escrow state model before building screens.

Hello! As per your project post, you’re looking to build an Escrow mobile application for buyers and sellers on iOS and Android, where payments are securely held, transactions are verified through OTP based confirmation, and funds are released only after successful delivery validation. The goal is to create a trusted peer to peer escrow system that reduces fraud, ensures transparency, and gives you full administrative control over disputes and transaction flow. My focus will be on delivering a secure escrow transaction platform, featuring: OTP based authentication using phone and email for both buyers and sellers, a transaction initiation system where buyers can create escrow deals by entering seller details and amount, Paystack integration for secure payment capture and hold state management, real time status tracking with notifications for every stage of the transaction, OTP based buyer confirmation before fund release, seller payout automation. I specialize in building fintech and marketplace applications using Flutter or React Native for mobile apps, with backend systems in Node.js or Firebase, combined with secure payment integrations like Paystack, Stripe, and webhook driven transaction workflows. Let’s connect to clarify your dispute handling rules, payout timing preferences, and whether you want identity verification (KYC) included in the MVP so we can structure the safest possible escrow flow. Best regards, Nikita Gupta.

@Jiboara

Hi! This escrow flow is very clear, and I can build it exactly as described using Laravel for the backend and React Native for the mobile apps on iOS and Android. Laravel will securely handle Paystack webhooks, transfers, disputes, OTP verification, and transaction logic, while React Native delivers a clean, trustworthy mobile experience for buyers and sellers. Firebase will handle real-time notifications and OTP delivery. The app will support OTP sign-in, Paystack checkout with “Payment Held” status, seller delivery confirmation, buyer OTP confirmation, and automatic fund release, with a web-based admin panel where you can pause, resolve, or refund transactions at any point. You’ll receive well-documented source code, TestFlight and Play Console builds, admin deployment steps, and 30 days of post-launch support. This can be production-ready in about 4–6 weeks. Would you like the admin panel to show a full timeline of each escrow transaction from start to finish for easier dispute handling?
