CipherPay | Update #3
A lot shipped since the last update.
UIVK Migration: Principle of Least Privilege
Shoutout to @nuttycom for pointing this out. CipherPay was storing the full viewing key (UFVK) when it only needs the incoming viewing key (UIVK) for address derivation and payment detection.
Fixed. Merchants can still register with either a UFVK or UIVK, if a UFVK is provided, we derive the UIVK server-side and discard the full key. Only the UIVK is stored (encrypted). CipherPay can detect incoming payments but never sees outgoing transactions from your wallet.
Less data stored = less risk.
Events & Ticketing
CipherPay now supports event ticketing natively. Merchants can create events with tiers, capacity limits, and sell tickets via shielded ZEC payments.
Agentic Payments - MPP
The @cipherpay/x402 package now supports MPP (Micropayment Protocol) alongside x402, two protocols, same shielded payment infrastructure.
zipher-cli | A Headless Zcash Wallet for AI Agents
This one isn’t part of CipherPay directly, but it completes the picture on the agent side.
@cipherpay/zipher-cli is a headless Zcash light wallet built for AI agents. It runs locally, manages keys, syncs with the network, and can pay for APIs autonomously, handling x402, MPP, and CipherPay sessions out of the box.
Think of it as the client-side counterpart to @cipherpay/x402. The middleware protects the API. zipher-cli lets agents pay for it. Fully shielded, both sides.
Early beta: npm install -g @cipherpay/zipher-cli
Dashboard & Website
Full responsive redesign of the merchant dashboard, mobile sidebar, tab layouts, agentic payments section with session tracking. Landing page modernized. FAQ rebuilt with accordion UX. Checkout UI polished for WCAG contrast compliance.
I won’t be able to make it to EthCC this time around, but if you’re there and find a merchant or product that should be accepting ZECm point them our way. Every merchant accepting Zcash makes the network more useful as actual money. The more places you can spend it, the stronger the case that shielded payments work at scale.
Still building.
