Swap cards directly with other collectors. Build multi-card offers, add cash, and settle atomically.
The Trade Center lets you swap slabs directly with another collector instead of going through the open market. Build an offer with one or more of your cards on one side and the cards you want on the other, then send it for review.
Trades rarely line up perfectly, so you can add cash to either side of an offer to balance the values. Put money in to chase a grail, or ask for cash on top when you are giving up the stronger card.
When a trade is accepted, every card and any cash on both sides changes hands in a single atomic step — either the whole trade clears at once, or none of it does. There is no window where one side has sent and the other has not, so you are never left exposed mid-swap.
Counter and decline freely
An offer is just an offer until both sides agree. You can counter, decline, or walk away with nothing committed, and nothing moves out of your collection until a trade settles.
GradedTown is a demonstration build with synthetic data — nothing here is a real collectible and no money changes hands. For the full overview, see How it works.
