Sending Jettons

Its possible to send Jettons to any account using wallet contracts presented in TonSdk.Contracts.Wallet and JettonWallet abstractions presented in TonSdk.Contracts.Jetton.

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 jetton master contract and jetton wallet owner
Address jettonMasterContract = new Address("/* jetton contract address */");

// get the jetton wallet address using TonClient: TonSdk.Client
Address jettonWallet = await tonClient.Jetton.GetWalletAddress(jettonMasterContract, wallet.address);

// 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");

// define jetton amount to send
Coins amount = new Coins(100); // for ex 100 jettons

// create jetton transfer options
JettonTransferOptions options = new JettonTransferOptions()
{
    Amount = amount,
    Destination = receiver
};

// create a message body for the jetton transfer
Cell jettonTransfer = JettonWallet.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 = jettonWallet,
                Value = new Coins(0.1), // amount in TONs to send
            }),
            Body = jettonTransfer
        }),
        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);
