Walk the floor
A card show, without the folding tables.
Cairn begins with the interface collectors already understand: a binder, a display case, other people's tables, and a pile you settle when the deal feels right.
Set your table
Lead with a display case, keep the rest in your binder, and mark exactly what is for sale or trade.
Display · sell · tradeMake a deal
Pay the posted ask directly, or change the terms and make an offer. The difference is always obvious.
Money stays visible

Meet Anko
The whole floor, in plain English.
Anko can put the right cards at the top, find copies across every table, explain a trade, and ask for better evidence. His intelligence is an asset—not a hidden authority.
Anko can recommend and prepare actions. He cannot spend, accept, or hand off your cards unless you give that authority explicitly.
The cards are the interface
Let the collection do the talking.
Search a character, a set, or a deck. See the cards first; open the evidence, price, and seller only when you need them.
Trust, without theater
Clear about what Cairn knows.
A scan can add clarity. It cannot prove a physical card is authentic. Cairn keeps those boundaries visible instead of collapsing every kind of trust into one badge.
Terms & state
The agreed cards, money, permissions, and transaction state can be recorded and enforced by the chosen settlement path.
Evidence & claims
Photos, scans, requests, and seller statements stay attached to the copy they describe and remain available for review.
Authenticity & condition
People, agents, or arbiters still interpret off-chain physical facts. Cairn does not turn an image into certainty.
Cairn shows what it can protect—and what it cannot.
Settle with intent
Checkout when it's a buy. A conversation when it isn't.
Paying a seller's posted ask should feel like checkout. Changing price, cards, or evidence turns it into an offer. Cairn keeps that handoff unmistakable.
