Wexon Whitepaper
A deep dive into the technical architecture, security model, and privacy features that power Wexon's non-KYC crypto card infrastructure.
Version 1.0 • December 2025
1. Abstract
Wexon presents a novel approach to bridging decentralized cryptocurrency assets with traditional payment infrastructure. By leveraging zero-knowledge proofs and a non-custodial architecture, Wexon enables instant issuance of virtual payment cards without requiring identity verification (KYC). This whitepaper outlines the technical foundations, security mechanisms, and privacy guarantees that make Wexon a trustless solution for cryptocurrency spending.
2. Introduction
The cryptocurrency ecosystem has achieved remarkable success in enabling peer-to-peer value transfer. However, a significant gap remains between holding crypto assets and using them for everyday purchases. Traditional crypto card providers require extensive identity verification, custody of funds, and often impose lengthy processing times.
Wexon addresses these challenges by providing: instant card issuance (under 60 seconds), no identity verification requirements, non-custodial fund management, and global acceptance through the Mastercard network.
3. System Architecture
Wexon's architecture consists of three primary layers: the Blockchain Interface Layer, the Processing Engine, and the Card Issuance Gateway.
Blockchain Layer
Monitors Solana blockchain for payment transactions and validates fund transfers.
Processing Engine
Converts cryptocurrency to fiat and manages the card issuance workflow.
Card Gateway
Interfaces with Mastercard network for global payment acceptance.
4. Non-Custodial Design
Unlike traditional crypto card providers, Wexon never takes custody of user funds. The payment flow operates as follows:
- 1User initiates card creation and selects amount
- 2Smart contract generates a unique payment address
- 3User sends crypto directly to the payment address
- 4Transaction is verified on-chain within seconds
- 5Card is issued immediately upon confirmation
- 6Funds are converted to fiat only at the moment of purchase
5. Zero-Knowledge Proofs
Wexon implements zero-knowledge proofs to verify payment validity without exposing transaction details. Our ZK implementation enables:
Payment Verification
Prove payment was made without revealing wallet address
Amount Validation
Confirm sufficient funds without exposing exact balance
Origin Masking
Hide the source of funds while proving legitimacy
Identity Separation
Decouple card usage from crypto identity
6. Privacy Model
Privacy is fundamental to Wexon's design. We implement multiple layers of privacy protection:
- No identity verification required for card issuance
- Email used only for card delivery, never stored long-term
- One-time payment addresses prevent transaction linking
- No logs of user activity or spending patterns
- Encrypted communication throughout the entire flow
- GDPR and privacy regulation compliant by design
7. Settlement Layer
Wexon's settlement layer processes cryptocurrency-to-fiat conversion in real-time. Key metrics include:
8. Conclusion
Wexon represents a significant advancement in cryptocurrency utility, enabling holders to spend their assets globally without sacrificing privacy or control. Through our non-custodial architecture, zero-knowledge proofs, and instant settlement layer, we provide a trustless bridge between decentralized finance and traditional payment infrastructure. As the crypto ecosystem matures, Wexon stands ready to serve as the primary gateway for real-world cryptocurrency spending.
