Class MintNftExtensions

public static Task<NftMintReceipt> MintNftAsync(this ConsensusClient client, EntityId token, ReadOnlyMemory<byte> metadata, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the mint.
EntityId	token	The identifier of the token type of NFTs to mint.
ReadOnlyMemory<byte>	metadata	The Metadata associated with the newly created NFT.
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<NftMintReceipt>	A mint transaction receipt indicating a successful operation.

Examples

// Mint a single NFT with UTF-8-encoded JSON metadata (CID-style strings
// are the typical choice — the network does not interpret the bytes).
// The supply key must sign. The receipt's SerialNumbers array holds
// the newly issued serial number.
var metadata = Encoding.UTF8.GetBytes("{\"name\":\"Artifact #1\"}");
var receipt = await client.MintNftAsync(nftCollection, metadata);
Console.WriteLine($"Minted serial: {receipt.SerialNumbers[0]}");

Exceptions

Type	Condition
ArgumentOutOfRangeException	If required arguments are missing.
InvalidOperationException	If required context configuration is missing.
PrecheckException	If the gateway node rejected the request upon submission, for example, if the token is already deleted.
ConsensusException	If the network was unable to come to consensus before the duration of the transaction expired.
TransactionException	If the network rejected the create request as invalid or had missing data.

MintNftsAsync(ConsensusClient, MintNftParams, Action<IConsensusContext>?)

Creates (Mints) new Non-Fungible Tokens (NFTs) under the specified token definition.

Declaration

public static Task<NftMintReceipt> MintNftsAsync(this ConsensusClient client, MintNftParams mintParams, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the mint.
MintNftParams	mintParams	The Parameters for minting the NFTs, including the metadata to be associated with each minted NFT.
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<NftMintReceipt>	A mint transaction receipt indicating a successful operation.

Examples

var mintReceipt = await client.MintNftsAsync(new MintNftParams
{
    Token = createReceipt.Token,

    {
        (ReadOnlyMemory<byte>)Encoding.UTF8.GetBytes("{\"name\":\"NFT #1\"}"),
        (ReadOnlyMemory<byte>)Encoding.UTF8.GetBytes("{\"name\":\"NFT #2\"}"),
        (ReadOnlyMemory<byte>)Encoding.UTF8.GetBytes("{\"name\":\"NFT #3\"}")
    }
});
Console.WriteLine($"Minted serial numbers: {string.Join(", ", mintReceipt.SerialNumbers)}");

Exceptions
