# Swapping coin for coin

> Two collectors, two vaulted coins, one even trade. No price, no payment — title moves one for one the moment the other side says yes.

## 1. What a swap is here

Collectors have always traded coin for coin across the table. A swap brings that trade onto the record: you point at a piece you want, offer one of yours for it, and if the owner agrees, both certificates change hands together. No money moves in either direction — a swap is an even trade of title, not a sale. Both coins stay exactly where they are, on their shelves in the vault, each now insured in its new owner's name.

## 2. Proposing costs nothing and moves nothing

From the page of any piece you could trade for, choose one of your own vaulted pieces, add a short note if you like, and propose. That is a question, not a commitment: the other collector has seven days to accept or decline, and until they answer you can withdraw it from your account. While a proposal is open, both pieces are simply asked to hold still — a piece already listed for sale, reserved by a payment, or sitting in another open swap cannot be proposed.

## 3. Accepting settles it, permanently

Acceptance is the settlement. In that moment the record updates both ways — your piece to them, their piece to you — and each certificate follows to its new owner's wallet. Both movements are written into each coin's provenance as one even trade. Like handing coins across a table, an accepted swap cannot be recalled, which is why the accept step asks you to confirm, plainly, exactly what you give and what you receive.

## 4. What the record shows

Each coin's history gains one honest line: swapped, from one collector to the other, naming the piece it was traded for. No price appears, because there was none — sale histories and price charts are untouched. There is no fee and no royalty on a swap; royalties belong to sales, and this is not one. It is the oldest trade in collecting, with a paper trail that keeps itself.
