Key API Patterns

​
1. Wallet Creation

const wallet = await tonClient.createWalletAccount({
  thresholdSignatureScheme: ThresholdSignatureScheme.TWO_OF_TWO,
  onError: (error: Error) => {
    console.error("Wallet creation error:", error);
  },
  backUpToClientShareService: true,
});

​
2. Message Signing

const signature = await tonClient.signMessage({
  message: "Hello, TON!",
  accountAddress: wallet.accountAddress,
});
// Returns base64-encoded Ed25519 signature

​
3. Transaction Signing

import { beginCell, toNano } from "@ton/ton";

// Serialize your cell to base64 before signing
const transferBody = beginCell()
  .storeUint(0, 32)
  .storeStringTail("Hello!")
  .endCell();

const signature = await tonClient.signTransaction({
  senderAddress: wallet.accountAddress,
  transaction: transferBody.toBoc().toString("base64"),
});
// Returns base64-encoded Ed25519 signature

​
4. Derive TON Address

// Synchronous — no await needed
const address = tonClient.deriveTonAddress({
  publicKeyHex: wallet.rawPublicKey,
  workchain: 0,
});

​
5. Wallet Retrieval

const walletDetails = await tonClient.getWallet({
  accountAddress: wallet.accountAddress,
});

​
6. Getting All Wallets

const allWallets = await tonClient.getTonWallets();

​
Available Functions

The TON SDK provides the following main functions:
  • createWalletAccount() - Create new TON wallet
  • importPrivateKey() - Import existing private key
  • getWallet() - Get specific wallet details
  • getTonWallets() - Get all TON wallets
  • deriveTonAddress() - Derive TON address from a public key hex
  • signMessage() - Sign messages (Ed25519, base64 output)
  • signTransaction() - Sign TON transactions (returns signed BOC)
  • exportKey() - Export wallet key data
  • offlineExportPrivateKey() - Export private key from key shares offline

​
Error Handling

Always implement proper error handling: 
try {
  const result = await tonClient.someFunction(params);
  console.log("Operation successful:", result);
} catch (error) {
  console.error("Operation failed:", error instanceof Error ? error.message : String(error));
}

​
Environment Setup

Make sure you have these environment variables: 
DYNAMIC_AUTH_TOKEN=your_auth_token_here
DYNAMIC_ENVIRONMENT_ID=your_environment_id_here

​
Dependencies

Install required packages: 
bun add @dynamic-labs-wallet/node-ton @ton/ton @ton/crypto @dynamic-labs-wallet/node
