// the params form when rotating a shared metadata reference across a
// set of NFTs in one collection. Method names: singular-one is
// `UpdateNftMetadataAsync`, plural-batch is `UpdateNftsMetadataAsync`.
var receipt = await client.UpdateNftsMetadataAsync(new UpdateNftsParams
{
    Token = collection,
    SerialNumbers = new long[] { 1, 2, 3 },
    Metadata = Encoding.UTF8.GetBytes("{\"cid\":\"bafy...\"}")
});
Console.WriteLine($"Update status: {receipt.Status}");
