+
+To retrieve the Jetton wallet's account jetton amount, owner identification information, and other details related to a specific Jetton wallet contract,
+use the `get_wallet_data()` [get method](/guidebook/first-smart-contract#6-2-reading-contract-data-with-get-methods) within the Jetton wallet contract.
+
+This method returns the following data:
+
+| Name                    | Type             | Description                                    |
+| ----------------------- | ---------------- | ---------------------------------------------- |
+| `balance`               | `VarUInteger 16` | the amount of nano tokens on the Jetton wallet |
+| `owner`                 | `MsgAddress`     | the address of owner's regular wallet          |
+| `jetton_master_address` | `MsgAddress`     | the address of the Jetton master contract      |
+| `jetton_wallet_code`    | `Cell`           | a code of the Jetton wallet                    |
+
+You can call the `get_wallet_data()` method from your favorite IDE:
+
+```javascript
+import { Address, TonClient } from "@ton/ton";
+
+async function main() {
+  const client = new TonClient({
+    endpoint: "https://toncenter.com/api/v2/jsonRPC",
+  });
+
+  const JettonwalletAddress = Address.parse(
+    "EQDmVdCZ2SALvyfCDVlPLr0hoPhUxgjNFtTAxemz9V_C5wbN",
+  );
+
+  const data = await client.runMethod(JettonwalletAddress, "get_wallet_data");
+
+  const Stack = data.stack;
+
+    console.log("Balance in nano tokens: ", Stack.readNumber());
+
+    // wallet address
+    console.log("Owner: ", Stack.readAddress().toString({ bounceable: false })); 
+
+    console.log("Jetton Master address: ", Stack.readAddress().toString());
+    
+    // default boc encoding in viewers 
+    console.log("Jetton Wallet code: ", Stack.readCell().toBoc().toString('hex')); 
+}
+
+void main();
+```
+
+Or call it through a web service, such as [Tonviewer](https://tonviewer.com/EQDmVdCZ2SALvyfCDVlPLr0hoPhUxgjNFtTAxemz9V_C5wbN?section=method):
+
+<Image

+  darkSrc="/resources/images/tonviewer/get-wallet-data-dark.png"
+/>
+
+Finally, you can get this information using the [API](https://toncenter.com/api/v3/jetton/wallets).
