How to transfer Gram, Jettons, and NFTs using WalletKit on the Android platform
All methods require an existing wallet instance. Create or retrieve a wallet before accessing data.
Create transactions to send Gram, Jettons, and NFTs, or generate previews for users.
Creating a transaction
Before sending any transaction to the blockchain, initialize it for the appropriate asset: Gram, Jetton, or NFT.
Gram
val message = TONTransferParams(
// TON wallet address
toAddress = "<TON_WALLET_ADDRESS>",
// 1 Gram in nanograms format
amount = "1000000000"
)
val transaction = wallet.createTransferTonTransaction(message)Jettons
val parameters = TONJettonTransferParams(
// TON wallet address
toAddress = "<TON_WALLET_ADDRESS>",
// Address of a Jetton minter contract
// E.g., EQCxE6mUtQJKFnGfaROTKOt1lZbDiiX1kCixRv7Nw2Id_sDs for USDT
jettonAddress = "<JETTON_ADDRESS>",
// 1 token in Jetton units
amount = "1000000"
)
val transaction = wallet.createTransferJettonTransaction(parameters)NFTs
val parameters = TONNFTTransferParamsHuman(
// TON wallet address
toAddress = "<TON_WALLET_ADDRESS>",
// Address of an NFT item contract
// E.g., EQDkT3BSIU3CTwnZG9ZIdyWYmcnuaAEwGr_dsS1RFYqBTanY
nftAddress = "<NFT_ADDRESS>",
)
val transaction = wallet.createTransferNFTTransaction(parameters)Transaction Preview
Once a transaction object is created, present a preview to the user before sending it.
val preview = wallet.getTransactionPreview(transaction)Sending a transaction
wallet.sendTransaction(transaction)
