​
new CulturaDigitalAssetClient()

new CulturaDigitalAssetClient(publicClient, walletClient, contractAddress): CulturaDigitalAssetClient

​
Parameters

publicClient
walletClient
contractAddress
`0x${string}`

​
Returns

​
Methods

​
mintDigitalAsset()

mintDigitalAsset(to, digitalAssetName, digitalAssetDescription, parentInfo, terms, tokenURI): Promise<bigint>
Mints a new digital asset token with specified metadata (React version using high-level contract interaction)

​
Parameters

to
`0x${string}` Address that will receive the minted token
digitalAssetName
string Name of the digital asset
digitalAssetDescription
string Description of the digital asset
parentInfo
readonly Readonly<{ rightsBoundAccount: `0x${string}`; royaltySplit: bigint; }>[] Array of parent digital asset information for derivative works
terms
Terms for the digital asset - can be a JSON object (to be uploaded to IPFS) or a string URI (pre-hosted) string | Record<string, any>
tokenURI
Token URI for the ERC-721 metadata - can be a JSON object (to be uploaded to IPFS) or a string URI (pre-hosted) string | Record<string, any>

​
Returns

Promise<bigint> The ID of the newly minted token

​
Remarks

This method mints a new digital asset token with licensing information. For derivative works, the parentInfo array should contain:
  • rightsBoundAccount: Address of parent digital asset collection (0x0 for original asset)
  • digitalAssetClass: Token ID of parent digital asset (0 for original asset)
  • royaltySplit: Percentage of royalties allocated to parent digital asset, expressed as a whole number (e.g., 10 for 10%).
Important: The sum of royaltySplit values across all parentInfo must equal exactly 75. (Note: This 75% value is currently hardcoded in the contract and may change in future versions).

​
