CXCash (CXCASH): Privacy Stablecoin Guide

What Is CXCash?

CXCash (CXCASH) is a privacy-first stablecoin built on the Aztec Network — a zero-knowledge rollup on Ethereum. CXCASH transfers are shielded by default at the contract level: the sender, receiver, and amount are hidden on-chain using zero-knowledge proofs, though wallets, the platform and network metadata may still record information.

Key Features

• Shielded by default: Contract transfers use ZK proofs to hide on-chain transaction details
• World-basket peg: Pegged to a basket of 6 currencies (USD, EUR, JPY, GBP, CNY, CHF)
• Built on Aztec Network: Inherits Ethereum's security through ZK-rollup technology
• No contract-level blacklist or pause: The token contract itself has no blacklist, pause, or surveillance functions; the platform, wallets and networks may still record activity
