Unique Gift - Happy Birthday
Published on September 2, 2026
What do you give the person who has everything? You give them something no one else can even see.
A Gift Given in Private
A “Happy Birthday Zcash 10” Shielded Asset isn’t just a digital image; it’s a postcard issued in the Zcash Ironwood pool, closed on chain and registered.
In an era where every transaction is tracked, every purchase profiled, and every digital move monitored, giving a gift that stays private is the modern luxury.
The Deep Water Advantage
An asset moves the way any shielded payment moves: wallet to wallet, with no custodian in between. The carrier note travels straight to a Unified Address, its proof constructed and verified by the sender’s own machine.
Nobody holds it on your behalf, and no marketplace stands between the giver and the receiver.
100% Sovereign Delivery
There are no intermediaries. There are no transparent ledgers. The asset’s ZMAP fingerprint — the Zcash Memo Asset Protocol — is inscribed directly into a transaction that routes through the shielded pool, arriving silently at your Zecboat wallet’s Unified Address.
What the Chain Actually Shows
The whole collection was minted in a single transaction at block 3,501,212, and anyone can look it up:
60fe6827be83f60e15d1e7071ef61ac5af71516793b96b01c9d52495926d35d1
What they will find is eleven Ironwood actions and nothing else: no transparent inputs, no transparent outputs, not one Orchard action.
Eleven blocks later, at block 3,501,223, the collection was closed: the issuer’s signed list of the ten, etched on chain, so no eleventh can ever be added. At block 3,501,228 it was registered in the Zecboat Registry, where any wallet can find it and check it for itself.
Eleven Actions, Ten Assets
The eleventh is change. A shielded note cannot be spent in part, only whole — so the mint was funded with a single note larger than needed, and the remainder came straight back. Exactly like handing over a twenty and receiving the difference.
On the chain, that change output is indistinguishable from the ten assets. Same pool, same bundle, nothing marking one as art and another as change. It did not even land at the end — it sat at index three, in the middle, because outputs are shuffled as the transaction is built.
Who Can See What
The issuer published this collection’s viewing key, so anyone can check the mint: ten postcards, one change note. After that, every transfer is private. Only the holder sees where a postcard goes next.
A private, peer-to-peer gift. When they open their wallet, the postcard is there, and only the mint is public.
