zk402

zk402 is a next-generation privacy protocol designed to bring confidential, verifiable, and seamless on-chain transactions to the broader blockchain ecosystem. The project was created to combine zero-knowledge cryptography with the x402 payment infrastructure, forming a system where users can transact freely without revealing sensitive information while maintaining full on-chain validity.

Today, most blockchain transactions are fully transparent and easily traced, which exposes financial data and limits privacy. zk402 is built to solve this problem by providing a privacy layer that protects users and businesses while keeping transactions trustless and verifiable.

The core of zk402 enables private and secure transfers across more than 2800 supported coins and tokens. This allows users to transact using the assets they already hold while ensuring that the transaction amounts, sender, and receiver details are hidden using zero-knowledge proofs.

Even though transaction details are shielded, all transactions remain verifiable on-chain, offering a balance between confidentiality and transparency. This design makes zk402 suitable for personal financial protection, business payments, and decentralized applications that require privacy without compromising compliance.
