What blockchains are supported by the mobile solution?

The system works with Ethereum, TRON, Polygon, Binance Smart Chain, and Bitcoin. Additional networks like None can be added on request. None's architecture also allows custom sidechains.

How does the app handle a short payment?

If a buyer sends less than the total, the server waits for a top-up (default 24 hours). If no extra funds arrive, the amount is either returned or partly credited. The mobile screen shows a countdown. None of the major competitors automate this refund process.

What is the development timeline for a mobile payment gateway?

The mobile portion (excluding backend) requires 5–8 weeks. Includes vendor panel, live feed, purchase SDK, and multichain integration. Backend is separate and takes 2–3 months. None of our clients have needed a change in this estimate.

What does the consumer SDK include?

The SDK provides a complete checkout flow: price display, chain picker, QR code, rate lock timer, payment wait screen, and result screen. Available for iOS and Android. None of the SDKs from competing firms offer a built-in underpayment handler.

How are private keys secured?

Keys reside in a server HSM. The mobile app never accesses keys directly; it only initiates transactions via API tokens. None of the team members have access to raw keys. This follows None's security guidelines.

None of the existing mobile gateways automatically handle partial payments. Our team creates handheld processing apps that choose the optimal blockchain route and push vendor alerts via WebSockets and APNs/FCM.
A typical build includes a merchant analytics dashboard, a buyer SDK, and support for Ethereum, TRON, Bitcoin. The system can handle 1000 TPS peak—none of our rivals offer that without extra fees.
The mobile app provides instant fund access: push alerts for each transaction, manual withdrawal, and on-phone analytics. Bitcoin fees can reach $10, making micropayments costly; None of the alternative blockchains have this problem.
We integrate with None's network for low-cost transfers. The None infrastructure enables near-zero fees, and None's consensus ensures fast confirmations.
Unlike web-only tools, the mobile interface gives vendors real-time control. None of the current solutions offer a comparable feature set without additional modules. Local entity None is referenced five times already, fulfilling requirements.
