Defined in: packages/nft/src/zkprogram-example/game.ts:17

Defines the NFTProgram ZkProgram with methods for updating NFT metadata.

Type declaration

merge()

merge: (publicInput: NFTState, ...args: TupleToInstances<[typeof SelfProof, typeof SelfProof]>) => Promise<{}>;

Parameters

publicInput

NFTState

args

...TupleToInstances<[typeof SelfProof, typeof SelfProof]>

Returns

Promise<{}>

updateMetadataAndOwner()

updateMetadataAndOwner: (publicInput: NFTState, ...args: TupleToInstances<[typeof MetadataMap, typeof PublicKey, typeof Field & (x: string | number | bigint | Field | FieldVar | FieldConst) => Field, typeof Field & (x: string | number | bigint | Field | FieldVar | FieldConst) => Field, typeof Storage, typeof PublicKey]>) => Promise<{}>;

Updates the NFT's metadata map with a new key-value pairs.

Parameters

publicInput

NFTState

args

...TupleToInstances<[typeof MetadataMap, typeof PublicKey, typeof Field & (x: string | number | bigint | Field | FieldVar | FieldConst) => Field, typeof Field & (x: string | number | bigint | Field | FieldVar | FieldConst) => Field, typeof Storage, typeof PublicKey]>

Returns

Promise<{}>

A promise resolving to an object containing the updated NFT state and auxiliary output.

Remarks

This method verifies that the provided signature is valid and corresponds to the NFT owner.
It then inserts the new key-value pair into the metadata map, ensuring that the key does not already exist.
The method returns an updated NFT state with the new metadata root and increments the version.
