Your stack.In perspective.
Everything you own, what it’s worth right now, and every invoice from your dealers. One private vault, free.
Know what you own.
Every coin and bar, its metal weight, what you paid, and its grade. Type it in, scan a slab, or import your spreadsheet.
See what it’s worth.
Valued at the same live prices dealers work from. Your gain, and your exposure to each metal, at a glance.
Know your exit.
What a local shop would likely pay today, and a record of every sale you make. Yours to export anytime.
One vault. Every bullionOS dealer.
Stack is your side of the network that dealers, wholesalers and refiners already run on. When a dealer invites you, what you buy from them arrives in your vault on its own.

Your invoices, kept for you.
Every invoice from the dealers you choose, in one place. No paper, no per-shop logins, no PINs.
You pick the dealers.
Only dealers you accept can send to your vault, and you can disconnect one whenever you like.
Your stack stays yours.
A dealer sees their own invoices to you and nothing else: not your collection, not your other dealers.
