Create an NFT Collection

An NFT collection (token class) defines the shared metadata — name, symbol, max supply, and management keys — for all NFTs minted under it. Individual NFTs are created later via minting. The Administrator key controls updates to the collection, while the SupplyEndorsement key controls minting and burning.

Code

var receipt = await client.CreateNftAsync(new CreateNftParams
{
    Name = "Sample NFTs",
    Symbol = "SNFT",
    Ceiling = 100,                         // max 100 NFTs in this collection
    Treasury = treasury,
    Administrator = adminEndorsement,
    SupplyEndorsement = supplyEndorsement,
    Memo = "My NFT collection"
});
Console.WriteLine($"Collection ID: {receipt.Token}");
