The NFI (Non-Fungible Intelligence) pallet allows for enabling NFI compatibility on new or existing collections. Once enabled, when an NFI-compatible NFT/SFT is minted, our trusted relayer will automatically generate the NFI data, storing the resulting NFIData on-chain.

Note: There may be an additional charge for NFTs minted with NFI enabled. See the MintFee section below. 0.5% of the mint fee is sent to the Vortex for redistribution to network participants.

​
Pallet Calls

​
Enable NFI

Enables NFI compatibility on a collection. Caller must be the collection owner

Namespace:

api.tx.nfi.enableNfi

Type:

function enableNfi(
  collection_id: u32,
  sub_type: SeedPrimitivesNfiNFISubType
)

​
Manual Data Request

Users can manually request NFI data if it does not already exist on a token. This can be used to manually request data for pre-existing tokens in a collection that has had NFI enabled Caller must be either the token owner or the collection owner Note. the mint fee will need to be paid for any manual request

Namespace:

api.tx.nfi.manualDataRequest

Type:

function manualDataRequest(
  token_id: (u32,u32),
  sub_type: SeedPrimitivesNfiNFISubType
)

​
Submit NFI Data

Submit NFI data to the chain. Caller must be the registered relayer. NFI must be enabled for the collection

Namespace:

api.tx.nfi.submitNfiData

function submitNfiData(
  token_id: (u32,u32),
  data_item: SeedPrimitivesNfiNFIDataType

function setRelayer(
  relayer: SeedPrimitivesSignatureAccountId20,
)

​
Set Fee To (Sudo Only)
