Methods
collectionKeys
▸ collectionKeys(): Promise<CollectionKey[]>
Retrieve the metadata that defines the NFT collection. Every issue call for this collection must provide a value for each element returned
Returns
Promise<CollectionKey[]>
Note
Each NFT must have an entry for each value, it should comply with the spec. In other words, the SDK only validates the presence of metadata keys, additional validation should be used when issuing

api/entities/Asset/NonFungible/NftCollection.ts:146
createdAt
▸ createdAt(): Promise<null | EventIdentifier>
Retrieve the identifier data (block number, date and event index) of the event that was emitted when the token was created
Returns
Promise<null | EventIdentifier>
Note
uses the middlewareV2
Note
there is a possibility that the data is not ready by the time it is requested. In that case, null is returned

details
▸ details(): Promise<AssetDetails>
Retrieve the NftCollection's data
Returns
Promise<AssetDetails>
Note
can be subscribed to
Overrides
Defined in
api/entities/Asset/NonFungible/NftCollection.ts:97
▸ details(callback): Promise<UnsubCallback>
Parameters
| Name | Type |

callback | SubCallback<AssetDetails> |
Returns
Promise<UnsubCallback>
Overrides

▸ exists(): Promise<boolean>
Determine whether this NftCollection exists on chain
Returns
Promise<boolean>
Overrides
BaseAsset.exists
Defined in
api/entities/Asset/NonFungible/NftCollection.ts:255
freeze
▸ freeze(opts?): Promise<GenericPolymeshTransaction<void, void>>
Freeze transfers of the Asset
Parameters
| Name | Type |
|---|---|
opts? | ProcedureOpts |
Returns
Promise<GenericPolymeshTransaction<void, void>>
Note
this method is of type NoArgsProcedureMethod, which means you can call freeze.checkAuthorization on it to see whether the signing Account and Identity have the required roles and permissions to run it

getCollectionId
▸ getCollectionId(): Promise<BigNumber>
Returns the collection's on chain numeric ID. Used primarily to access NFT specific storage values
Returns
Promise<BigNumber>
Defined in
api/entities/Asset/NonFungible/NftCollection.ts:268
getIdentifiers
▸ getIdentifiers(): Promise<SecurityIdentifier[]>
Retrieve the Asset's identifiers list
Returns
Promise<SecurityIdentifier[]>

getNft
▸ getNft(args): Promise<Nft>
Get an NFT belonging to this collection
Parameters
| Name | Type |
|---|---|
args | Object |
args.id | BigNumber |
Returns
Promise<Nft>

|---|---|
entity | Entity<unknown, unknown> |
Returns
boolean

issue
▸ issue(args, opts?): Promise<GenericPolymeshTransaction<Nft, Nft>>
Issues a new NFT for the collection
Parameters
| Name | Type |
|---|---|
args | IssueNftParams |
opts? | ProcedureOpts |
Returns
Promise<GenericPolymeshTransaction<Nft, Nft>>
Note
Each NFT requires metadata for each value returned by collectionKeys. The SDK and chain only validate the presence of these fields. Additional validation may be needed to ensure each value complies with the specification.
Note
this method is of type ProcedureMethod, which means you can call issue.checkAuthorization on it to see whether the signing Account and Identity have the required roles and permissions to run it
Defined in
api/entities/Asset/NonFungible/NftCollection.ts:59
toHuman
▸ toHuman(): string
Return the NftCollection's ticker
Returns
string

api/entities/Asset/Base/BaseAsset.ts:342
transferOwnership
▸ transferOwnership(args, opts?): Promise<GenericPolymeshTransaction<AuthorizationRequest, AuthorizationRequest>>
Transfer ownership of the Asset to another Identity. This generates an authorization request that must be accepted by the recipient
Parameters
| Name | Type |
|---|---|
args | TransferAssetOwnershipParams |
opts? | ProcedureOpts |
Returns
Promise<GenericPolymeshTransaction<AuthorizationRequest, AuthorizationRequest>>
Note
this will create Authorization Request which has to be accepted by the target Identity.
An Account or Identity can fetch its pending Authorization Requests by calling authorizations.getReceived.
Also, an Account or Identity can directly fetch the details of an Authorization Request by calling authorizations.getOne
Note
this method is of type ProcedureMethod, which means you can call transferOwnership.checkAuthorization on it to see whether the signing Account and Identity have the required roles and permissions to run it

unfreeze
▸ unfreeze(opts?): Promise<GenericPolymeshTransaction<void, void>>
Unfreeze transfers of the Asset
Parameters
| Name | Type |
|---|---|
opts? | ProcedureOpts |
Returns
Promise<GenericPolymeshTransaction<void, void>>
Note
this method is of type NoArgsProcedureMethod, which means you can call unfreeze.checkAuthorization on it to see whether the signing Account and Identity have the required roles and permissions to run it
