The basic configuration earlier is enough to outline necessary wallet information and initialize the WalletKit, but it isn’t enough for deeper interactions with the blockchain. For that, you need to set up at least one TON wallet contract.

​
Initialization

  1. First, obtain the signer. It can be instantiated from a mnemonic, from a private key, or be made custom.
  2. Then, select a wallet adapter — it is an implementation of the WalletInterface type for a particular TON wallet contract. Currently, WalletKit provides two: WalletV5R1Adapter (recommended) and WalletV4R2Adapter. Adapter takes in a signer from the previous step and a number of options, namely:
    • network — TON Blockchain network: Network.mainnet(), Network.testnet(), or Network.custom(chainId).
    • client — API client to communicate with TON Blockchain. Use kit.getApiClient(network) to get the client for the specified network from the networks configuration passed during WalletKit initialization.
    • walletId — identifier of the new wallet, which is used to make its smart contract address unique.
    • workchain — either 0 for the basechain (default), or -1 for the masterchain.
    TypeScript
    import {
  // Network object
  Network,
  // Latest wallet version (recommended)
  WalletV5R1Adapter,
  defaultWalletIdV5R1,
  // Legacy wallet version
  WalletV4R2Adapter,
  defaultWalletIdV4R2,
} from '@ton/walletkit';

const walletAdapter = await WalletV5R1Adapter.create(signer, {
  network: Network.mainnet(),
  client: kit.getApiClient(Network.mainnet()),

  // Either 0 for the basechain (default),
  // or -1 for the masterchain
  workchain: 0,

  // Specify an ID for this wallet when you plan
  // on adding more than one wallet to the kit
  // under the same mnemonic or private key.
  //
  // In such cases, ID is used to make wallet addresses unique,
  // because the same ID for the same mnemonic results in wallets
  // with the same address, i.e., the same smart contract.
  walletId: defaultWalletIdV5R1, // 2147483409
});
  3. Finally, pass the adapter to the addWallet() method of the kit to complete the wallet initialization process:
    TypeScript
     // Notice that addWallet() method returns an initialized TON wallet,
 // which can be used on its own elsewhere.
 const wallet = await kit.addWallet(walletAdapter);
 console.log('Wallet address:', wallet.getAddress());

Private key

Custom signer

​
From mnemonic

To initialize a TON wallet from an existing BIP-39 or TON-specific mnemonic seed phrase, the signer should be instantiated with the fromMnemonic() method of the utility Signer class of the WalletKit.
TypeScript
import {
  // Handles cryptographic signing
  Signer,
  // Latest wallet version (recommended)
  WalletV5R1Adapter,
  // Network object
  Network,
} from '@ton/walletkit';

// 1.
const signer = await Signer.fromMnemonic(
  // (REQUIRED)
  // A 12 or 24-word seed phrase obtained with general BIP-39 or TON-specific derivation.
  // The following value assumes a corresponding MNEMONIC localStorage entry
  // that contains 24 space-separated seed phrase words as a single string:
  localStorage.getItem('MNEMONIC')!.split(' '), // list of 24 strings
  {
    // Type of derivation used to produce a mnemonic.
    // If you've used a pure BIP-39 derivation, specify 'bip-39'.
    // Otherwise, specify 'ton'.
    // Defaults to: 'ton'
    type: 'ton',
  },
);

// 2.
const walletAdapter = await WalletV5R1Adapter.create(signer, {
  network: Network.mainnet(),
  client: kit.getApiClient(Network.mainnet()),
});

// 3.
const wallet = await kit.addWallet(walletAdapter);

​
From private key

To initialize a TON wallet from an existing private key, the signer should be instantiated with the fromPrivateKey() method of the utility Signer class of the WalletKit. If there is a mnemonic, one can convert it to an Ed25519 key pair with public and private key by using the MnemonicToKeyPair() function.
TypeScript
import {
  // Handles cryptographic signing
  Signer,
  // Latest wallet version (recommended)
  WalletV5R1Adapter,
  // Conversion function
  MnemonicToKeyPair,
  // Network object
  Network,
} from '@ton/walletkit';

// 1.
const signer = await Signer.fromPrivateKey(
  // Private key as a hex-encoded string or Uint8Array of bytes.
  // The following value assumes a corresponding PRIVATE_KEY localStorage entry
  // that contains the private key as a hex-encoded string:
  localStorage.getItem('PRIVATE_KEY')!,
);

// 2.
const walletAdapter = await WalletV5R1Adapter.create(signer, {
  network: Network.mainnet(),
  client: kit.getApiClient(Network.mainnet()),
});

// 3.
const wallet = await kit.addWallet(walletAdapter);

​
From custom signer

To provide a custom signing mechanism as an alternative to using a mnemonic phrase or a private key, create an object of type WalletSigner and then pass it to the target wallet adapter’s create() method. The signer object has to have two fields:
  • Signing function of type ISigner, which takes an iterable bytes object, such as array, Uint8Array, or Buffer, and asynchronously produces an Ed25519-encoded signature of the input as Hex. The Hex type is a string containing a hexadecimal value that starts with an explicit 0x prefix.
    TypeScript
    type ISigner = (bytes: Iterable<number>) => Promise<Hex>;
  • Relevant Ed25519 public key of type Hex.
    TypeScript
    type Hex = `0x${string}`;
A custom signer is useful to maintain complete control over the signing process, such as when using a hardware wallet or signing data on the backend.
TypeScript
import {
  // Network object
  Network,
  // Latest wallet version (recommended)
  WalletV5R1Adapter,
  // Conversion function
  MnemonicToKeyPair,
  // Utility function to convert an array of bytes into a string of type Hex
  Uint8ArrayToHex,
  // Utilify function to obtain an Ed25519 signature
  DefaultSignature,
  // Handles cryptographic signing
  type WalletSigner,
  // String with a hexadecimal value, which starts with the `0x` prefix
  type Hex,
} from '@ton/walletkit';

// A Ed25519 key pair from a mnemonic
const keyPair = await MnemonicToKeyPair(
  // The following value assumes a corresponding MNEMONIC localStorage entry
  // that contains 24 space-separated seed phrase words as a single string:
  localStorage.getItem('MNEMONIC')!.split(' '),
  'ton',
);

// 1.
const signer: WalletSigner = {
  // The following is a simple demo of a signing function.
  // Make sure to replace it with a production-ready one!
  sign: async (bytes: Iterable<number>): Promise<Hex> => {
    return DefaultSignature(Uint8Array.from(bytes), keyPair.secretKey);
  },

  // Public key as a Hex
  publicKey: Uint8ArrayToHex(keyPair.publicKey) as Hex,
};

// 2.
const walletAdapter = await WalletV5R1Adapter.create(signer, {
  network: Network.mainnet(),
  client: kit.getApiClient(Network.mainnet()),
});

// 3.
const wallet = await kit.addWallet(walletAdapter);

​
Multiple wallets

You can add multiple TON wallets to WalletKit and switch between them as needed.
TypeScript
const wallet1 = await kit.addWallet(walletAdapter1);
const wallet2 = await kit.addWallet(walletAdapter2);
// ...
const walletN = await kit.addWallet(walletAdapterN);
Providing the same wallet adapter to the kit multiple times will return the wallet that was already added in the first attempt.

​
Methods

​
Get a single wallet

The getWallet() method expects a wallet identifier string. Note that the same wallet on different chains must have different identifiers. Compose it via the createWalletId() helper function:
TypeScript
import { createWalletId, Network, type Wallet } from '@ton/walletkit';

// Using the helper function to create a wallet identifier.
const walletId = createWalletId(
  Network.mainnet(),
  walletAdapter.getAddress(),
);
const wallet: Wallet | undefined = kit.getWallet(walletId);

if (wallet) {
  console.log('Wallet address: ', wallet.getAddress());
}

​
Get all wallets

To obtain all added wallets, use the getWallets() method of the initialized kit.
TypeScript
const wallets: Wallet[] = kit.getWallets();
wallets.forEach(w => console.log('TON wallet address:', w.getAddress()));

​
Remove a single wallet

The kit.removeWallet() method accepts either a walletId or the adapter instance itself. Compose the identifier via the createWalletId() helper function or pass the adapter used when adding the wallet:
TypeScript
import { createWalletId, Network } from '@ton/walletkit';

// Using the helper function to create a wallet identifier.
const walletId = createWalletId(
  Network.mainnet(),
  walletAdapter.getAddress(),
);
await kit.removeWallet(walletId);

// Alternatively, pass the adapter directly.
await kit.removeWallet(walletAdapter);

​
Clear all wallets

To remove all previously added wallets from the kit, use the clearWallets() method of the initialized kit.
TypeScript
await kit.clearWallets();
