PRXVT
Open-source privacy SDK that adds unlinkable, zero-knowledge payments on top of the x402 agent payment standard.
Overview
PRXVT builds privacy-preserving infrastructure for AI-agent commerce, starting with px402, a privacy wrapper around the x402 payment standard where an agent obtains blinded credentials so payment patterns stay confidential. Its open-source Privacy SDK uses Groth16 zero-knowledge proofs and encrypted note storage, and the team is building related tools such as HushKit for private agent-to-agent communication. PRXVT integrates with ERC-8183 agentic-commerce hooks and has a $PRXVT token; the token is speculative and the cryptography has not been independently audited.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 49 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
