Technology designed for real-world payments
X-Cash combines blockchain infrastructure with practical tools to enable simple, accessible, and reliable digital payments — even in low-connectivity environments.
Architecture
X-Cash is built as a hybrid architecture combining scalable EVM infrastructure with a privacy-focused blockchain layer. This allows the system to support real-world payments, flexible privacy, and future ecosystem expansion.
Base (EVM)
Scalability, liquidity, and ecosystem access. The fast layer for everyday transactions and DeFi connectivity.
X-Cash L1
Privacy-focused blockchain layer for private transactions and user control. Monero-grade cryptography.
Bridge
Bridge layer for moving assets between Base and L1. Currently in development.
X-Wallet
A browser-first privacy wallet designed for real-world use.
Local Key Management
Private keys never leave the user's device. All transaction signing happens locally.
Flexible Privacy Controls
Choose between private and transparent transactions depending on your needs.
Dual Network Access
Direct interaction with both L1 and Base from a single wallet interface.
Built for Payments
Optimized for fast payment flows, privacy controls, and everyday transaction management.
X-Cash App (Next Step)
X-Cash evolves into a mobile-first application designed for everyday payments, discovery, and interaction.
NFC Contactless Payments
Tap-to-pay for fast, familiar checkout at any merchant.
QR-Based Payments
Universal access — works on any smartphone with a camera.
Unified Experience
One app for users and merchants — pay, accept, track, and discover.
Identity and Activity
Designed to support identity, reputation, and activity tracking as the product grows.
Hybrid Transactions
X-Cash combines blockchain security with real-world usability by supporting different transaction modes depending on context.
On-Chain Transactions
Secure and verifiable. Full blockchain settlement for transactions that need it.
Fast Local Confirmations
Low-value payments can use local exchange flows for faster user experience, with later network settlement.
Phone-to-Phone
Direct interaction between devices for the fastest possible payment experience.
Payments without Internet
X-Cash is designed to work even in environments with limited or no internet access.
How it works
Local Transaction Signing
Transactions are signed locally on the device — no server connection needed to authorize a payment.
USSD Fallback
Signed transaction payloads can be transmitted via USSD protocol — a lightweight operator-level channel that works on any mobile phone, even without internet or a smartphone.
Network Relays
Signed transactions can be forwarded to the network when connectivity becomes available.
Why it matters
Works in Poor Infrastructure
Enables payments in regions where internet coverage is unreliable or expensive.
Beyond Internet-First Markets
Designed for regions where reliable connectivity is not always available.
Everyday Transactions Anywhere
Small, everyday payments should work everywhere — not just in cities with 5G.
Direct Phone-to-Phone Payments
For fast, low-value transactions, X-Cash supports direct communication between devices without waiting for full network confirmation.
NFC Tap Payments
Tap phones together to pay — instant, familiar, and reliable.
QR Interaction
Scan to exchange payment data directly between devices.
Offline Exchange
Local transaction exchange between devices with reduced dependency on live connectivity.
Security and Privacy by Design
X-Cash separates transaction privacy from usability, allowing users and businesses to choose the level of transparency they need.
Local Key Management
Keys are generated and stored on your device. Nothing is transmitted to any server.
Non-Custodial Architecture
No one else can access, freeze, or control your funds. You hold your own keys.
Flexible Privacy Model
Private when you need it, transparent when it helps — the choice is always yours.
Transparent for Business
Businesses can use transparent transaction flows where compliance, reporting, or customer trust require it.
