Gaming NFTs on Mythos

Mythos extends Substrate’s pallet_nfts to enable zero-deposit minting, serial issuance, and cross-game metadata locks tailored for Mythical titles.

Core Capabilities

• Free-to-Mint Collections: Collection and item deposits are set to zero, letting studios airdrop assets without reserve capital.
• Serial & Pre-Signed Minting: mint_pre_signed enables controlled releases (e.g., playoff passes) while MintSettings enforce windows and ownership prerequisites.
• Attribute Governance: Attribute namespaces (CollectionOwner, ItemOwner, Pallet, Account) let designers lock rarity traits while still enabling player-driven upgrades.

Example: Minting a Nitro Nation Crate

A production mint executed in block 2,611,955 shows Mythos’ NFT pipeline in action:

{
  "extrinsic_hash": "0x6f26cdb2c3398f2cabaa0bf51d3c8ec3f3cbe75ffb8b9b8853718055517b2497",
  "call": "nfts.mint",
  "collection": "0xfa",
  "item": "0x02",
  "owner": "0x6f88…b0d5"
}

Mint Workflow

1. Create Collection – Call pallet_nfts.create with mint settings (start/end block, whitelist) and any metadata URI.
2. Configure Attributes – Use set_attribute or force_set_attribute for cosmetics, team names, or rarity. Lock values for seasonal archives.
3. Distribute Items – Choose between mint, force_mint, or mint_pre_signed depending on automation, KYC, or sponsor involvement.
4. Lifecycle Management – Approve transfers, set prices, or initiate swaps via pallet_marketplace and pallet_dmarket.

Tips for Game Studios

• Batch NFT drops with pallet_multibatching to keep UX smooth even during primetime events.
• Combine Beamable inventory sync with Mythos NFTs so Unity/Unreal builds reflect ownership instantly.
• Align DAO governance proposals with upcoming drops to secure MYTH staking incentives.
