Zoniqx zPayRails

Privacy-Preserving Fiat-to-Stablecoin and Crypto Payment Infrastructure
Book a Demo

Zoniqx zPayRails bridges traditional finance and blockchain with cryptographic trust. Built on zkTLS (Zero-Knowledge Transport Layer Security) and Trusted Execution Environments (TEE), it enables secure, compliant, and verifiable fiat-to-crypto transactions, without ever exposing personal or payment data on-chain.

What is Zoniqx zPayRails?

Zoniqx zPayRails is a next-generation on/off-ramp infrastructure that allows users and institutions to move between fiat, stablecoins, and crypto assets with cryptographic privacy, verifiability, and regulatory compliance.

By integrating Bridge’s global fiat payment network with zkTLS proofs and modular smart contracts

Zoniqx zPayRails ensures:

Privacy: No sensitive data is revealed during transaction verification.

Verifiability: All payments are cryptographically attested and validated on-chain.

Compliance: Tiered KYC/AML and auditable transaction trails.

Speed: Instant settlement and minimal fees across chains.

The Zoniqx zPayRails Advantage

Privacy-Preserving Architecture

  • zkTLS verifies fiat transactions without exposing user details.


  • TEE environments guarantee proof integrity and resistance to side-channel attacks.


  • Future-ready for MPC (multi-party computation) validation via EigenLayer.

Seamless Fiat-to-Crypto Bridge

  • Direct integration with Bridge Elements and Checkout.


  • End-to-end process: user pays → proof generated → on-chain verification → crypto delivered.


  • Fully asynchronous pipeline with idempotent transaction queues.


Multi-Chain, Non-Custodial Settlement

  • Blockchain-agnostic: supports Ethereum, Solana, Bitcoin, and Layer-2s.


  • Tokens delivered directly to the user’s wallet, no custodial risk.


  • Universal Router integration for swaps and gas optimization.

Security by Design

  • Reentrancy protection and input validation in smart contracts.


  • Role-based access control and slippage limits.


  • External smart contract audits and TEE attestation.



Regulatory Alignment

  • Tiered KYC model for global compliance.


  • Integrated AML monitoring through Bridge and partner services.


  • zkTLS documentation supports regulators without exposing private data.


Core Components

Frontend

React + TypeScript app with embedded Bridge checkout and wallet connect.

Smart Contracts

  • PaymentBridge – Accepts proofs and orchestrates transfers.
  • Verifier – Validates zkTLS proofs and extracts payment data.

  • TokenSwap – Executes swaps through Universal Router.

Security

TEEs, encrypted memory, certificate pinning, formal verification.

zkTLS Layer

Wraps TLS communications in zero-knowledge proofs for private verification.
