An IGO (initial game offering) launchpad sells a blockchain game's tokens, in-game NFTs such as characters, land or items, or both, before the game is fully launched. Technically it combines a token-sale launchpad with an NFT mint platform. Its real difficulty is judging games, because many funded games never ship or see their economies collapse.
For a background explainer on the IGO trend itself, see the blog post on initial game offerings in NFT gaming. This page is about building and running the platform.
What an IGO sells
| Asset | Standard | Sale mechanics | Key risk |
|---|---|---|---|
| Governance or utility token | ERC-20 / BEP-20 or chain equivalent | Tiered or overflow sale, vesting, DEX listing | Securities treatment; unlock-driven sell pressure |
| Unique items (characters, land) | ERC-721 | Fixed-price or Dutch-auction mint, allow-lists | Value depends on a game that may not ship |
| Fungible or semi-fungible items | ERC-1155 | Batch mints of item types with fixed supplies | Oversupply if the game later mints more |
| Mystery boxes | ERC-721 or ERC-1155 with delayed reveal | Buy box, reveal randomized contents later | Loot-box and gambling regulation |
Platform components
- Project onboarding. Game details, playable build links, token and NFT plans, team identity and audit reports.
- Token sale module. The same staking tiers, allow-lists, sale and vesting contracts as any token launchpad.
- NFT sale module. Mint contracts with supply caps per item type, allow-list phases, and per-wallet limits.
- Fair reveal. For randomized items, commit to a provenance hash before the sale and use verifiable randomness, such as Chainlink VRF, to assign traits after minting so neither the team nor buyers can game the outcome.
- Royalties and metadata. EIP-2981 royalty info, permanent metadata storage (for example IPFS with pinning, or on-chain), and clear terms about what the NFT actually grants in the game.
- Distribution into the game. Item NFTs must be recognized by the game's servers or contracts; agree the integration format before the sale.
NFT mint mechanics in general are covered in the NFT launchpad guide.
Vetting games is the hard part
A pre-launch game is a promise. The 2021 to 2022 play-to-earn boom showed how quickly game economies can unravel: Axie Infinity's reward token lost most of its value as new-player inflows slowed, and its Ronin bridge lost hundreds of millions of dollars in a 2022 hack. Many other funded games were quietly abandoned. A responsible IGO launchpad checks:
- Is there a playable build, and is the game fun without the token?
- Economy design. Where tokens and items are created (faucets) and destroyed (sinks), and whether the economy depends on a constant stream of new buyers.
- Funding runway. Whether the raise covers development to launch, and what happens if it does not.
- Team. Verified identities and a game-development track record, not only crypto experience.
- Contracts. Independent audits of token, NFT and in-game contracts, and limits on future minting.
- Vesting. Team and investor unlocks that do not land on players right after launch.
Legal points specific to games
Paid mystery boxes with randomized contents can be treated as gambling in some jurisdictions; Belgium's gambling regulator, for example, has treated paid loot boxes as illegal gambling since 2018. Marketing NFTs or tokens with promises of earnings or returns increases the chance they are treated as investment products. Keep sale materials focused on in-game use, avoid earnings claims, and get advice on each asset type.
Cost and timeline drivers
As a reasoned estimate, adding an NFT sale module with fair reveal and game integration to an existing token launchpad takes two to three months for two or three engineers plus audits. Building both from scratch, with multichain support and a vetting pipeline, is roughly four to six months. The game itself is a separate and much larger undertaking; see Web3 game development.
Frequently asked questions
How is an IGO different from an IDO?
An IDO sells a project's fungible token. An IGO is game-focused and often sells in-game NFTs alongside or instead of a token, which adds minting, reveal and game-integration work.
Should a game sell NFTs before launch?
Only if the team can deliver the game and honor what the NFTs promise. Early NFT sales create obligations and, if the game slips, angry holders.
Are mystery boxes allowed?
Not everywhere. Some countries treat paid randomized items as gambling. Fixed-content sales or free reveals are safer, and geo-restriction may be needed.
