Claim this listing →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.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

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. 38 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. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-23, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
