Sending NFTs

Its possible to send Nft items to any account using wallet contracts presented in TonSdk.Contracts.Wallet and NftItem abstractions presented in TonSdk.Contracts.nft.

For example, we will use WalletV4. You can find more examples for different contracts here.

// create http parameters for ton client 
HttpParameters tonClientParams = new HttpParameters 
{
    Endpoint = "https://toncenter.com/api/v2/jsonRPC",
    ApiKey = "xxx" 
};

// create ton client to fetch data and send boc
TonClient tonClient = new TonClient(TonClientType.HTTP_TONCENTERAPIV2, tonClientParams);

// create new mnemonic or use existing
Mnemonic mnemonic = new Mnemonic();

// create wallet options
WalletV4Options options = new WalletV4Options()
{
    PublicKey = mnemonic.Keys.PublicKey,
};

// create wallet instance
WalletV4 wallet = new WalletV4(optionsV4, 2); 

// define the address of the nft collection
Address collection = new Address("/* nft collection address */");

// define index of the nft what will send
uint index = 10;

// get the nft items address using TonClient: TonSdk.Client
Address nftItemAddress = await tonclient.Nft.GetItemAddress(collection, index);

// define receiver address or get receiver address from ton domain name system
// Address receiver = new Address("/* destination address */");
Address receiver = await tonClient.Dns.GetWalletAddress("continuation.ton");

// create transfer options
NftTransferOptions options = new NftTransferOptions()
{
    NewOwner = receiver
};

// create a message body for the nft transfer
Cell nftTransfer = NftItem.CreateTransferRequest(options);

// getting seqno using tonClient
uint? seqno = await tonClient.Wallet.GetSeqno(wallet.Address);

// create transfer message
ExternalInMessage message = wallet.CreateTransferMessage(new[]
{
    new WalletTransfer
    {
        Message = new InternalMessage(new InternalMessageOptions
        {
            Info = new IntMsgInfo(new IntMsgInfoOptions
            {
                Dest = nftItemAddress,
                Value = new Coins(0.1), // amount in TONs to send
            }),
            Body = nftTransfer
        }),
        Mode = 1 // message mode
    }
}, seqno ?? 0); // if seqno is null we pass 0, wallet will auto deploy on message send

// sign transfer message
message.Sign(mnemonic.Keys.PrivateKey);

// get message cell
Cell cell = message.Cell;

// send this message via TonClient
await tonClient.SendBoc(cell);
