Built for collectors, day one

A marketplace built for collectors who read the books.

Comics, Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Manga, Riftbound, Dragon Ball — bought, sold, and traded by collectors as equals. Trade is a verb, not a footnote.

Three-mode commerce, equal weightBuy, sell, or trade — same protections, same fairness, mode-appropriate dispute resolution.

The verticals

8 verticals. One marketplace. Equal weight.

Every category gets the same catalog data quality, the same grading services, the same trust signals, and the same buy / sell / trade tools. The platform doesn’t play favorites.

Three modes of commerce

Buy, sell, or trade. The platform treats them equally.

Most marketplaces treat trading as a feature bolted on. SlapSwap was designed around the trade primitive from the start — the same protections and fairness, with mode-appropriate dispute resolution across all three.

Mode 01

Buy

Browse listings, make an offer, or buy outright. Every order carries the same protections and dispute resolution as a trade.

  • Search and filter across every vertical
  • Watch items and get wantlist-match alerts
  • Seller handle, grade, and cert on every listing
  • Honest catalog data — name, set, era, key issue
Browse listings →

Mode 02

Sell

List individual items across every vertical. The listing form captures the data that matters — grading service, grade, cert number, format, and price.

  • List in minutes from any catalog item
  • Fixed price, or trade-eligible — your call
  • Manage every listing from one place
  • A public storefront shows your trust signals
List an item →

Mode 03

Trade

Propose item-for-item trades, hybrid trades with a cash adjustment, or pure swaps — cross-vertical included. Trade is a first-class action, not a footnote.

  • Offer your listings plus optional cash
  • Accept, decline, or counter any proposal
  • Cross-vertical trades (comic ↔ Pokémon ↔ Magic)
  • The same protections as buying or selling

The trust architecture

Listing Verified. Never Authenticated.

The platform verifies that items match seller representations. It does not certify authenticity — grading services and the original creators do that. The distinction is constitutional, not marketing.

01 · The facility

Dallas-based inspection

A partner-led inspection space in Dallas, with chain-of-custody photography on every routed item.

02 · The threshold

Tiered inspection routing

The model: required on every $2,500+ item, required on trades from $1,000+, optional below. Buyers can opt into inspection at any tier — full schedule on the fees page.

03 · The credibility

Senior hobby specialists

Editorial credibility through senior hobby specialists. Advisory relationships are in development. The editorial firewall is a constitutional commitment.

04 · The registry

A planned stolen-property registry

A planned 501(c)(3) registry. Items registered in a collection would carry provenance fingerprints across ownership transfers.

Spotting a Real LOB-001 1st Edition Blue-Eyes White Dragon

The English Blue-Eyes is a 2002 card, not 1999 — and the card-back rosette, not the front, is where most fakes die.

From the curators

Lists are identity. Curation is the algorithm.

SlapSwap separates curators from influencers. Authority comes from set-completion, annotation depth, and verified collections — not from follower counts.

◆

Curator profiles

Featured lists, set-completion authority, and annotation depth — surfaced through editorial selection, not engagement metrics.

Curator profiles and featured lists launch with the community phase.

How it works

Four steps. No hidden mechanics.

The flow is plain: make an account, build a wantlist, transact, and settle. Fees, the inspection model, and dispute resolution will be documented in plain language.

Step 01

Create your account

Account creation takes a minute. Choose the verticals you collect — you can add or change them anytime.

Step 02

Build your wantlist

Add items to your wantlist. Wantlist-match alerts surface new listings the moment they post — the deeper your wantlist, the better it works.

Step 03

Buy, list, or propose a trade

Browse and make offers, list your own items, or propose a trade — same-vertical or cross-vertical, with optional cash adjustments.

Step 04

Receive, inspect, settle

Higher-value items will route through the Dallas inspection facility on the way to you. Settlement happens on-platform.
