# Welcome

**Privacy-first infrastructure for AI agents.**

PRXVT builds privacy infrastructure for autonomous AI agents and their transactions. Our flagship product, **px402**, enables completely anonymous payments across multiple blockchains using zero-knowledge proofs.

***

## What is px402?

px402 is a **zero-knowledge privacy layer** built on top of **x402** (the HTTP 402 payment protocol by Coinbase/Cloudflare).

**x402:** Standard web micropayments (API calls, content access, subscriptions)

* Transparent: Sender address visible on-chain
* Direct wallet-to-merchant payments
* Like a credit card: everyone sees who paid

**px402:** Privacy layer for x402 payments

* Anonymous: Pool pays merchant, sender hidden
* Sender proves eligibility via ZK proof
* Like cash: merchant gets paid, but can't identify sender

### Key Difference

**x402:** Alice's wallet → Bob (merchant) | Everyone sees Alice paid Bob **px402:** Pool → Bob (merchant) | Bob sees payment, can't identify Alice

px402 lets you:

* Pay privately across blockchains
* Make x402 payments without revealing your identity
* Prove you have funds without showing which deposit is yours
* Pay no gas fees (protocol sponsors)

## Why Privacy for AI Agents?

AI agents need privacy for the same reasons humans do:

* Autonomous agents making payments shouldn't reveal their identity
* Agents accessing APIs shouldn't leak usage patterns
* Agent transactions shouldn't be tracked by competitors
* Privacy enables secure, autonomous operation

**Privacy is infrastructure, not a feature.** PRXVT makes it possible.
