Welcome to FlipKey.gg

FlipKey.gg is a marketplace utility for game studios, built on Base. List your game licenses and keys and reach players directly — there’s no blockchain to build or integrate on your end. Players pay by card — more payment options are coming.

How It Works

1. Set Up — Create your publisher account and connect your payout details. No blockchain knowledge required.
2. List a Game — Add your game and the platforms you sell keys for (Steam, Epic, PSN, and more). Set price and quantity per platform, and point each one at your redemption link.
3. Sell — List on our marketplace and link directly from your website. Players buy with a card; you get paid — no middleman taking a massive cut.
4. Deliver — Each sale mints a use-bound license the buyer owns. They redeem it into their platform, and your key is handed over only after FlipKey.gg verifies the purchase on-chain.

Key Concepts

• Listings & Drops — Each game you sell is a listing with its own per-platform inventory. Set price and supply for Steam, Epic, PSN, and more — all under one listing.
• Licenses — Every key you sell is a use-bound license: an NFT the buyer owns, redeemable once into the platform it's for. The license is non-transferable — it can't be traded or resold; redemption or refund are the only paths.
• Redemption — Buyers redeem a license into their platform through your redemption link. FlipKey.gg verifies ownership on-chain before delivering the key — no platform integration needed on your side beyond the link.
• Simple API — Your game or store calls our API to verify licenses, receive activation webhooks, and manage players. No blockchain knowledge needed.

Our Business Model

Think of it like Amazon. Amazon's profit comes from logistics — not from taxing sellers into the ground. FlipKey.gg works the same way: we profit on transactions, not on your success. Our marketplace exists to help you sell more, not to make you pay more.

FlipKey.gg charges a small transaction fee, because our incentive is aligned with yours: the more you sell, the more we both earn.

Take Control of Your Game Keys

Right now, millions of dollars in game keys are resold on grey-market sites. Publishers see none of that money — and stolen keys, chargebacks, and fraud cost the industry billions.

FlipKey.gg changes that. A license is use-bound — it can't be transferred, resold, or flipped, so there's no grey-market window. And the chain is identity-attached end to end: the license is minted to the buyer's wallet against their card payment, and at redemption the holder proves both wallet control and their platform identity (e.g. a Steam sign-in) before any key is released — the key value never touches FlipKey.gg. So if a key surfaces where it shouldn't, the redemption traces back to a verified person — wallet, platform account, and the original purchase — and you act on that identity with your own platform tools (ban, revoke, reissue). Far better than vending blind through distributors.

What this catches — and what it doesn't

A resold or leaked key traces back to the redeemer — the wallet, platform account, and card recorded at redemption. That's the identity you act on. What FlipKey.gg can't see on its own is the eventual activator when a raw key is resold and entered on a different account — that happens on the platform's side. Matching redeemer-to-activator needs a platform key-status lookup (e.g. Steam's querycdkey), a publisher-side step. And tracing is forensic, not prevention: a determined fraudster can redeem behind a throwaway account — but unlike an anonymous grey-market key, you're left with a correlatable, bannable cluster (account ↔ wallet ↔ card) you can revoke and freeze on-chain, instead of eating a blind chargeback.

Beyond keys: bundles & a tradable secondary market

Selling keys is just the start. With FlipKey.gg you can bundle a license with a tradable in-game item — a cosmetic or reward granted through your SDK — that adds value at full price instead of discounting the key. Those items are designed to list on our marketplace where fans resell them, turning resale into marketing reach and a royalty you set on every trade — FlipKey.gg takes only its standard marketplace fee.
