Layer 1 — Shielded deposit
You fund from a shielded ZEC address using zk-SNARK proofs. The deposit is verified on-chain without exposing sender identity or full transaction graph to the spend layer.
z-addr → deposit pool → credited balance
Move from shielded ZEC to everyday purchases with one private prepaid card. Use it wherever Visa is accepted—online, in-store, and abroad.
Simple flow
Sign up with email only. Receive a virtual Visa instantly — no ID, no bank link, no selfie.
Send from your shielded wallet to a unique deposit address. Balance credits after network confirmations.
Tap, swipe, or pay online at any Visa merchant — restaurants, supermarkets, coffee shops, Amazon, Uber, hotels, and more. They see a normal prepaid card, not your ZEC.

Architecture
ZCard separates funding privacy from spend convenience. Your shielded deposit never has to touch a KYC exchange.
You fund from a shielded ZEC address using zk-SNARK proofs. The deposit is verified on-chain without exposing sender identity or full transaction graph to the spend layer.
z-addr → deposit pool → credited balance
An internal ledger maps confirmed deposits to your card balance. This ledger stores no on-chain linkage — only allocation amounts and card ID. Withdrawals back to ZEC are optional.
confirmations ≥ N → balance += amount − fee
When you pay, the issuer authorizes against your prepaid balance via standard Visa networks. The merchant receives a normal authorization — no ZEC, no wallet address, no chain data.
auth request → balance check → approve / decline
Privacy boundary: on-chain shielded in · fiat-rail spend out. No KYC exchange in the middle.
Transparent ZEC deposits may be supported with a privacy warning. Shielded is the default and recommended path.
Deposits credit after a configurable confirmation threshold to prevent double-spend and reorg risk.
Non-KYC tiers cap monthly load and max balance — standard for prepaid programs and keeps onboarding frictionless.
Card identity is decoupled from deposit addresses. Fresh deposit addresses can rotate per load.
Privacy model
Limits subject to program partner requirements. Higher tiers may require optional verification.
