Swap trading post

Bulk team/year/set trading for base-card collectors — without per-card inventory.

Swap preview

Trade team lots by year and set — without cataloging every card.

Swap is a dedicated bulk-trading surface for base-card collectors who want to post Haves, track Wants, and move into offers fast.

Stack account wiring will connect here later. For now, these screens show the route shape and where signed-in trade actions will land.

Route skeleton

A clean launchpad for the pages shipping in this chunk.

Overview

See the new bulk-trading surface taking shape.

Post a listing

Create a Have or Want around team, year, set, and approximate count.

Posting will require a Stack-linked sign-in once account wiring is in place.

Matches

Review Haves that overlap with your active Wants — without card-by-card cataloging.

Personalized matching will appear here after auth bridging lands.

Inbox

Keep offers, counters, and shipping coordination in one place.

Inbox access will use the existing account system later.

Post a Have

Describe the team/year/set you are offering, add an approximate count, and attach photos.

Track matching Wants

Surface overlap at the bulk-listing level instead of forcing every card into a checklist.

Finish in thread

Accept an offer, coordinate shipping in chat, and stop there — no payments or escrow layer.

Sample listings keep the route grounded without implying inventory-level detail yet.

Bulk-only trading

This product is for team/year/set lots and base-card swaps, not graded chase cards or per-card inventory.

Have-first discovery

Public browse centers on Haves, while Wants power matching and trade proposals behind the scenes.

Local red accent only

Swap gets its own red-600 identity without changing the rest of cardboard.rip.
