Guidance only — not legal, financial, or tax advice. Publishers are responsible for their own compliance (consumer disclosure, securities, EULA/transfer terms).
Getting Started
Sandbox Quickstart
Try everything with zero risk: list a game, sell an item, run a giveaway, and buy from yourself with a test card — in about 15 minutes, no integration required.
Getting Started with FlipKey.gg
Set up your publisher account, list your game licenses on FlipKey.gg, and earn more from every sale — at a fraction of traditional platform fees.
Your Account
Mint Credits
How promotional mints are priced: your first 1,000 are free, then $0.02 each, prepaid. What spends credits, what never does, and how campaign budgets are reserved.
Team & Roles
Owner, admin, and the specialist seats — a refunds role for support staff, a minting role for community managers. Who can spend money, who can manage the team.
Refunds
The two refund windows — automatic before redemption, your queue after — and how to work requests with a dedicated refunds seat.
Game Distribution
Beta & Press Access
Invite your beta list — and your press list — by email — access that can't be traded, shared, or resold, revocable per-person, with one API call to gate your build. Revoke a whole press wave in one click. First 1,000 promotional mints free.
Standard License Keys
Single-use game licenses the buyer owns and redeems once into their platform — non-transferable by design, and every redeemed key stays identity-traceable.
Freebies on License Sales
Attach a free bonus item to a sale — the “buy here, get this skin free” hook. Create it once, attach it to any campaign, swap it anytime. Soulbound to the buyer; usable in-game right away.
Integration
Choosing a Key Station
Hosted by GameLicense ($20/year founding price), your own $6/month droplet with one command, or the full kit on your own stack: what each one can do, and which droplet to pick.
SDKs & Downloads
Start here if you're building the publisher side: the starter kit, the Redeem SDK, the Watch-Drop SDK — what each one is for, the install commands, and the checksum to verify the kit against.
Redemption SDK & Link Test
The spec every listing depends on: your redemption page, the drop-in Redeem SDK widget, and the HMAC link-test handshake your backend must answer before a listing goes live.
Webhooks
The signed events FlipKey.gg sends your backend — item grants at redemption, the token mirror at every sale — with the signature scheme, retries, and idempotency rules.
API Reference
The full REST API, browsable — every endpoint your backend can call, with schemas and auth requirements.
Publisher Starter Guide
The starter kit's full manual — quickstart, configuration, the going-live checklist, the port-it-to-your-stack spec, and the twelve-item key-security checklist.
Publisher Starter Backend
A complete runnable redemption backend — key storage, the link-test handshake, the Redeem SDK page, CSV key import. SQLite by default; MySQL/Postgres drivers included. Unzip, fill in .env, run.
Creator Marketing
Watch-Drop Campaigns & Giveaways
Build one drop campaign that every streamer can run — reward viewers for watching with claimable items that onboard new players.
Twitch Watch-Drops: Setup & Integration
End-to-end: set up the Twitch campaign, configure tiers in FlipKey.gg, and wire the one signed webhook (with SDK) that hands each claim off to you to grant.
Attribution & Affiliates
Track which creator drove each sale via referral links; you run the affiliate payouts.
Economy & Revenue
Item trading on our marketplace is coming.
The Royalty Revenue Loop
How NFT royalties turn traditional money sinks into sustainable revenue.
In-Game Items & Gifting Advanced
Tradeable, giftable in-game items that generate royalty revenue on every sale.
Crafted Assets Advanced
Player-created items whose value comes from time and effort invested.
Monuments of Power Advanced
Time-limited NFTs that grant real gameplay power — then expire.
Proof of Ownership Advanced
On-chain verification of authorship, rights, and creation.
Player Engagement
GRID — Gamer Reputation ID
A verified player identity system that brings age-appropriate matchmaking, reputation scoring, and community trust to every game on the platform.
Achievement Badges
Soulbound proof of what a player accomplished — a memory on the blockchain.
Collectibles & Cosmetics
Cosmetic items — skins, dyes, emotes — tradeable and visual-only.
Captured Moments Advanced
Gameplay clips minted as NFTs — the actual moment, owned forever.
Access Passes
Hold-to-access NFTs for areas, features, tiers, or communities.
Living NFTs Advanced
NFTs whose on-chain data evolves over time — reputation, progression, stats.
Trust & Safety
Verified Credentials Advanced
Soulbound proof of demonstrated skill — the end of player-to-player scams.
Anti-Cheat Marks Advanced
Soulbound negative reputation NFTs — ecosystem-wide cheater accountability.
Articles marked Advanced require on-chain integration inside your game — a web3 library (ethers, viem, wagmi) talking directly to Base. These features — like minting in-game items, tracking achievements on-chain, or issuing credentials — need your game client or server to communicate with the blockchain directly. Basic features like selling game licenses and keys only require our marketplace and API.
All of these are ideas of what can be accomplished utilizing the blockchain. This space is evolving — expect new use cases and integrations to emerge over time as NFT experts and quality game designers push the boundaries of what's possible.
